Conventional systems and methods for masking surfaces such as wall, glass, brick, or the like typically involve use of a masking tape, which is typically one to two inches wide but can be bought in wider sizes, for example, five to six inches wide. Typically, the user of masking tape must carefully unroll the tape while pressing it against a surface to be painted (or stained or otherwise have a chemical or other substance applied) in order to protect an adjacent surface. Much of what can be a time consuming effort can be spent attempting to achieve a straight edge between the surface to be painted and the surface being masked because the tape doesn't have sufficient rigidity to maintain a desired masking edge. Similar to masking tape, masking paper comes in a roll and therefore requires unrolling the paper and having to carefully hold the paper so that it doesn't coil while pressing it against the wall. Generally, masking tape and masking paper are very similar in that the nature of their packaging (being rolled) results in their having considerable flexibility that requires the user to use two hands to pull it sufficiently taunt to create a straight masking edge.
In a typical scenario, a user of a roll of masking tape unrolls and presses the tape to a wall surface immediately adjacent to a piece of molding, for example, door or window molding, crown molding, baseboard, chair rail, etc., so as to prevent paint being applied to the molding from getting onto the wall while also achieving a straight masking edge. Moreover, to protect a wider portion of the wall surface, a newspaper (or another protective material such as plastic, etc.) is often placed over the masking tape such that there is room to then add additional tape to hold it in place, perhaps using additional tape to hold an outer edge of the newspaper to the wall. Considerable time is usually required to apply (or install) the masking materials (tape, newspaper, etc.) and, after paint has been applied and dried, the masking materials are for the most part not usable for protection of another surface. As such, to paint a large number of rooms involving lots of moldings, a large amount of protective materials will typically be discarded.
In another typical scenario, considerable time is often spent placing masking tape around each window pane in a window before painting or staining the window. Again, often newspaper is placed over the portion of the panes not having masking tape and additional tape applied so as to fully cover the window panes. As with the previous scenario, considerable time and effort is required to install the masking materials, the installed masking materials are typically unusable for protecting additional surfaces, and a large quantity of masking materials are required to protect surfaces.
Therefore, there exists a need for an improved system and method for surface masking.
Briefly, the present invention is a masking panel designed to cover a protected first surface, such as a wall surface, floor surface, ceiling surface, door surface, door frame, fire place surface, window, window frame, window pane, decorative molding, chair rail or baseboard, while paint, stain, sealant or other chemicals is applied to an adjacent second surface. The masking panel includes a reusable protective material to be placed over at least a portion of the protected first surface. The reusable protective material includes at least one masking edge to create a masking boundary between the protected first surface and the adjacent second surface, where the at least one masking edge has a masking edge shape that is pre-fabricated to substantially match the masking boundary.
The making panel also includes one or more holding edges. The masking panel additionally includes an adhesive fixed on the reusable protective material in the direction of the protected first surface along the at least one masking edge to secure the reusable protective material to the protected first surface.
The masking panels in an embodiment can be used to protect any surface, such as a wall, a brick surface, a ceiling, a floor, or the like, from paints, stains, sealants, or any other substance that can be applied to a surface. Moreover, the masking panels can be used to protect any desired surface, for example, a surface of a building, a surface of a boat, a surface of an airplane, a surface of a vehicle, or any other desired surface.
In an embodiment, the masking panels are made out of a protective material such as paper, plastic, or similar material sufficient for masking, and are pre-fabricated to have a desired masking area shape and a masking edge having a desired shape for installation against a corresponding surface having an edge shape corresponding to a masking boundary that is complementary to the desired masking edge shape. A desired masking edge shape can be a straight edge, a curved edge, or any other desired shape corresponding to the boundary between a surface to be masked (or protected) and a (non-protected) surface intended to have a substance, for example paint, applied to it. A desired masking edge shape may correspond to a measured masking edge shape, for example, a shape of a molding measured using a measurement tool such as a shaping template or contour gauge. Multiple protective materials can also be combined to produce a masking panel. The masking panels of the embodiment have a thickness that provides rigidity sufficient to maintain a desired masking edge shape during installation.
In another embodiment, the masking panel of the invention has a reusable pressure sensitive adhesive associated with the masking edge intended to bond (or adhere) the protective material to a surface being masked. As such, the adhesive is located between the protective material and the surface being masked. In an embodiment of the invention, the adhesive associated with the masking edge is located along the masking edge so as to prevent any leakage of paint onto the surface being masked. Adhesive may be located at one or more other locations on a masking panel, such as other edges, corners, locations within the inner portions of the panel, or any other desired location that might be appropriate to hold the masking panel in place after installation.
One or more different adhesives can be used with the invention, where the one or more different adhesives may vary in the extent to which they cause a masking panel, or portion of a masking panel, to bond to a surface, or a portion of a surface, being protected. For example, an adhesive(s) used with a masking panel intended to protect a sheet rock wall surface might be different from an adhesive(s) used to adhere a masking panel to a brick surface. Generally, the bonding characteristics of a given adhesive used in accordance with the present invention can be tailored to meet specific requirements of the surface being masked.
In another embodiment, a magnetic strip can be used in place of a reusable pressure sensitive adhesive to adhere a masking panel to a metal surface.
In a further embodiment, the masking panels of the present invention consist of rectangular sheets of heavy duty paper, each having at least one masking edge and having sufficient rigidity to maintain the masking edge during installation. Under one embodiment, such panels have a relatively strong adhesive along a side providing a sufficiently rigid straight masking edge and weaker adhesive on sides other than the side providing the masking edge.
In an embodiment, the panels are packaged in a stack such that the adhesives are also used to attach masking panels to each other in addition to adhering to masked surfaces.
With one approach, the panels are packaged in a stack whereby adhesive is on alternating edges of each successive panel such that successive panels have masking edges oriented 180° relative to each other. With this approach, the thickness of the stack remains substantially unbiased from one side to the other. With another approach, the panels are packaged in a stack whereby masking edges and corresponding adhesive layers are stacked on top of each other.
In another embodiment, one or more portions of adhesives have a removable strip that must be removed to expose the adhesive prior to installation.
In a further embodiment, a long masking panel has perforations thereby allowing individual paint panels of desired lengths to be produced by separating perforations. In a similar arrangement, long masking panels have folds enabling their length to be reduced while packaged. These two approaches can be combined such that panel portions can be folded at perforation lines allowing individual portions to be used separately, or allowing two or more panel portions to be unfolded and used together without tearing the perforation lines between the panel portions. Alternatively, a long masking panel can be folded and then later unfolded and torn or cut to achieve a desired length.
In an embodiment, masking panels are designed such that a portion of a panel along the masking edge has a lesser thickness than the remainder of the panel providing a region for a strip covering an adhesive such that the thickness of that portion, the adhesive, and the covering strip have a total thickness that substantially equals the remainder of the panel. This arrangement enables packaging where the stack of panels is not biased towards one side. Moreover, the thicker portion of the panel not having the covered adhesive provides additional control to the user due to its additional rigidness. Under a similar arrangement, a masking tape can be attached along an edge of a more rigid protective material such that a portion of the tape is able to be used for achieving a masking seal.
In an embodiment, a masking panel has adhesive on at least one side of its top surface and adhesive on at least one opposing side its bottom surface. The adhesive on the bottom surface is used to provide a masking edge along a surface to be painted. The adhesive on the top surface is used to provide an attachment edge for attaching the masking panel to additional protective material in order to extend masking area coverage. After the masking panel has been installed alongside a surface to be painted, a second masking material, such as plastic sheeting, can then be attached to the adhesive on the top surface of the masking panel so as to extend the masking surface area, for example to protect an entire floor.
In a further embodiment, the masking panel can optionally include an anti-wetting coating applied to a masking edge. Under one arrangement an anti-wetting coating comprises a Teflon coating. Under another arrangement an anti-wetting coating comprises a wax coating.
The present invention is described with reference to the accompanying drawings. In the drawings, like reference numbers indicate identical or functionally similar elements.
Additionally, the left-most digit(s) of a reference number identifies the drawing in which the reference number first appears.
The present invention will now be described more fully in detail with reference to the accompanying drawings, in which the preferred embodiments of the invention are shown. This invention should not, however, be construed as limited to the embodiments set forth herein; rather, they are provided so that this disclosure will be thorough and complete and will fully convey the scope of the invention to those skilled in the art. Like numbers refer to like elements throughout.
The present invention provides an improved system and method for surface masking involving a masking panel having at least one masking edge pre-fabricated to have a masking shape that substantially matches a desired masking boundary between a non-protected surface intended to have a substance (e.g., paint) applied to it and an adjacent protected surface intended to be masked so the substance will not be applied to it. The masking panel has sufficient rigidity to maintain the masking edge shape during installation along the making boundary. The panels have a pressure sensitive adhesive enabling them to be easily attached to a protected surface and also to be easily removed and reinstalled against a similar surface. The masking panels of the present invention can be used to protect any surface associated with a building, such as a wall, fire place bricks, window glass, a ceiling, a floor, or the like, from paint, stains, sealants, or any other substance that one might want to apply to a surface. Moreover, the masking panels of the present invention can be used to protect other desired surfaces, for example, a surface on a boat, a surface on an airplane, a surface on a vehicle, or any other desired surface where a masking panel having a desired masking edge shape meeting masking requirements, for example a straight masking edge, a curved masking edge, or a masking edge having a masking edge of any other desired shape can be used. A masking edge shape may correspond to a measured masking edge shape such as the shape of a molding measured with a measurement tool such as a contour gauge or shaping template. Masking panels can also have multiple masking edges.
In accordance with the present invention, masking panels having a desired masking area shape are made out of paper, plastic, or similar material sufficient for masking and have at least one masking edge pre-fabricated to have a desired masking shape for installation against a corresponding surface to create a masking boundary having shape characteristics complementary to (i.e., substantially matching) the desired masking edge shape. For example, many surfaces that are painted in a home, for example a window frame, have a straight edge next to a surface to be masked, for example a wall surface, where a masking panel that provides a straight masking edge is desirable since it can be easily placed alongside the straight edge of the window frame and adhered to the wall surface for masking purposes. Other shapes for masking panels can be used in accordance with the invention as appropriate to provide other desired masking edge shapes, for example, a masking edge with a desired curvature. The masking panels of the invention are also referred to herein as paint panels, protective panels, or panels. They are also referred to by the inventors as Mask-it™ panels.
The masking panel of the invention has a thickness that provides rigidity sufficient to provide and maintain a desired masking edge shape during installation. In other words, the rigidity of the panel itself provides and maintains the masking edge without requiring any force to be applied to the panel to create the masking edge, such as having to use two hands to pull masking tape or paper taunt so as to create a straight masking edge. Such sufficient rigidity can be understood by comparing the rigidity of a piece of poster board to the rigidity of a piece of notebook paper. With a piece of poster board oriented vertically such as would be typically required to mask a vertical wall, one can hold the bottom corner of the right side of the poster board and the edge of the left side will remain substantially straight such that one could easily place the left side of the poster board alongside the straight edge of a window frame. However, should one similarly hold the right bottom corner of a piece of notebook paper oriented vertically, its lack of sufficient rigidity will cause it to fold over or coil about the holding point such that it cannot be easily placed alongside the straight edge of a window frame. This same sufficient rigidity test can be used with a piece of masking tape or masking paper, which will tend to coil due to the thinness and lack of rigidity of the tape or paper. The thickness and therefore rigidity of masking tape and masking paper, in contrast to the masking panel of the present invention, are specifically selected to enable the tape or paper to be packaged and dispensed in rolls. The masking panels of the present invention have thickness and rigidity making them unsuitable for being packaged and dispensed in a roll but instead more suited to being stacked or folded on top of one another. For both cost and aesthetic reasons, it is generally desirable to achieve such sufficient rigidity with as thin a protective material as possible while also ensuring the material is able to prevent leakage through it.
The masking panel of the invention has a reusable pressure sensitive adhesive, for example an adhesive comparable to that adhesive used with masking tape, associated with the masking edge. In a preferred embodiment of the invention, the adhesive associated with the masking edge is located along the masking edge so as to provide a masking seal that prevents leakage of any paint beneath the installed masking panel onto the surface being masked. Masking panels may also include additional adhesive at one or more other locations, such as other edges, corners, locations within the inner portions of the panels, or any other desired location that might be appropriate to hold the masking materials in place after being installed. Adhesive locations, as with the shape of the masking panel, may be tailored based on the specific characteristics of the surfaces being painted and masked, which is referred to herein as the masking scenario. In a manner similar to determining the appropriate thickness to achieve sufficient rigidity and ability to protect a surface, the bonding ability of the adhesive would typically be a tradeoff between the characteristics of an adhesive required to achieve a bond that will hold the masking panel in place and achieve a seal along the masking edge sufficient to prevent leakage, while at the same time being easy to remove and not damaging the masked surface, such as removing paint from the protected surface. Moreover it is desirable that all adhesive remain on the panel when it is removed from a surface. As referred to herein, a relatively strong adhesive, such as is used with common masking tapes and masking papers, provides a seal sufficient to prevent leakage and a bond that will hold the masking panel in place while a relatively weaker adhesive, such as is used with Post-it® notes, provides a bond that will hold the masking panel but may or may not provide a sufficient seal to prevent leakage.
Typically, a user of a masking panel would hold the panel by a holding edge opposite the masking edge when installing it alongside the edge of the surface being painted and then use the other hand to press the panel against the surface being masked so as to bond the adhesive to that surface and achieve a seal along the masking edge to prevent leakage of paint (or some other substance) onto the masked surface. One or more different adhesives can be used with the invention, where the one or more different adhesives may vary in the extent to which they cause a protective panel, or portion of a protective panel, to adhere to a surface, or a portion of a surface, being protected. For example, an adhesive(s) used with a masking panel intended to protect a sheet rock wall surface might be different from an adhesive(s) used to adhere a paint panel to a brick surface.
Generally, the extent to which a given adhesive bonds to a given surface can be designed to meet bonding requirements of a surface to be masked, as appropriate. Moreover, a magnetic strip can be used in place of an adhesive to enable a masking panel to adhere to a metal surface.
Under one arrangement, the masking panels of the present invention consist of rectangular sheets of paper having at least one masking edge and having sufficient rigidity to enable a user to hold the panel so as to place a straight edge up against a surface to be painted, for example molding around a door, and press the panel where adhesive is present to adhere the panel to a surface being masked, such as a wall surface surrounding the door molding. Under one arrangement, such panels have one relatively light (easily removed) adhesive on sides of the panel not providing a masking edge, and relatively heavier adhesive along a side providing a masking edge.
Under another arrangement, an anti-wetting coating is applied to a masking edge to shed paint. An anti-wetting coating may comprise a Teflon coating or a wax coating.
Throughout this specification, and particularly in the drawings, areas of masking panels having adhesives are represented by a darkened pattern. One skilled in the art will recognize that when the masking panels are used that the adhesive would be between the protective material and the masked surface (e.g., a wall) and as such the adhesive may not be visible when looking at the masking panel from the side not having the adhesive. As such, in accordance with one embodiment of the invention, markings can be placed on the side of the protective material opposite the side having an adhesive in such a manner as to indicate where adhesive is present on the other side. Different colors or markings may also indicate adhesives intended for a masking edge versus other adhesives intended for bonding purposes only. Where drawings depict usage of masking panels having darkened patterns, those darkened panel should be interpreted as indicating locations of adhesive between the protective material and the masked surface and indicating optional markings indicating adhesive locations. Anti-wetting coatings would coincide with the outermost edge of the darkened patterns corresponding to masking edges.

Generally, one or more protective materials can be used to produce a masking panel and any such protective material(s) can have one or more thicknesses as desired for a given application. For example, a masking tape can be attached along an edge of a more rigid protective material such that a portion of the tape is able to be used for achieving a masking seal while the protective material has sufficient rigidity to maintain a masking edge during installation. However, with this approach, it is best that the masking tape have sufficient rigidity so as to not bend during installation.
Referring to
One skilled in the art will recognize that various techniques can be used to provide rigidity to a masking edge in accordance with the present invention to include providing a reinforcing material, for example a metal wire or metal strip, within the protective material making up the masking panel. The thickness of a masking panel may vary from one side to another, for example in a shape somewhat resembling a wedge. Adhesives can be applied to masking panels during manufacturing or prior to use. For example, a two-sided masking tape could be applied alongside an edge of a protective material to produce a masking edge and could similarly be applied to the other side of a masking panel to attach additional protective material.
Based on the forgoing, a masking panel is fully described that has at least one masking edge that are pre-fabricated to have a masking shape that substantially matches a masking boundary between a protected surface and a non-protected surface where a substance, such as paint, stain, sealant or oil, is to be applied on the non-protected surface. As such, the masking panel creates the desired masking boundary when installed on a surface to be protected that is adjacent to the surface on which the substance is applied. The masking boundary can be a straight line or a curved line or some combination. The masking boundary can also comprise two straight lines that are perpendicular to each other. A protective material has at least one masking edge having a masking edge shape that is pre-fabricated to substantially match a masking boundary. The protective material, such as paper, cardboard, plastic or rubber, has sufficient rigidity to maintain the masking edge shape between a protected surface and an unprotected surface adjacent to the protected surface during installation of the masking panel. The protected surface can be a wall surface, a brick surface, a ceiling surface, a floor surface, a surface of a building, a glass surface, a surface of a boat, a surface of an airplane, or a surface of a vehicle. The protective material can be sized to fit a window pane or around a molding. An adhesive layer is positioned on one side of the protective material in sufficient quantity at an orientation that holds the masking edge against the protected surface at a desired position relative to the unprotected surface so as to prevent the substance that is being applied to the unprotected surface from being applied to the protected surface. The adhesive layer can have opposing adhesive sides and a removable strip can also be place on the adhesive layer.
According to some of the more detailed of the present invention, the adhesive layer comprises a pressure sensitive adhesive being adhered to the protected surface by pressure applied during the installation of the masking panel by a first hand while a second hand holds a non-adhesive holding edge. A masking edge can be a straight edge, an outside corner edge, an inside corner edge, a curved edge, or a measured edge or a plurality of masking edges that are perpendicular to each other.
According to other more detailed of the present invention, the making panel can include at least one fold or performation. Another adhesive layer may be positioned on an opposing side of the one side of the protective material in sufficient quantity at an orientation to attach an extension protective material to the protective material. A removable strip covering the other adhesive layer enables the extension protective material to be attached to the masking panel. The protective material can be different form the extension protective material, for example, a non-rigid material.
While particular embodiments of the invention have been described, it will be understood, however, that the invention is not limited thereto, since modifications may be made by those skilled in the art, particularly in light of the foregoing teachings.
