Deck rejuvenation system and method

Abstract

A deck resurfacing material is made of a kiln-dried, southern yellow pine wood board. The board has had treatment with a non-metallic preservative and stabilizer system. The board has a top, a length, two ends and two sides with side edges. A grooved pattern on top includes flat areas at each side, two sets of grooves interiorly of the flat areas and another flat area interiorly between the two sets of grooves. The board has a transition from the top to each side edge that is radiused and the side edges are not tongue-and grooved. The two ends have end matching in the form of a tongue at one end of the board and a groove at the other end of the board so the board can be installed with end matching to a like board, and a transition from the top to each end that is a radiused.

Description

BACKGROUND OF THE INVENTION

Wooden decks that have aged or that need a new look have historically been expensive and time consuming to restore. The existing wooden decking material has typically been mounted on joists such as 2×6 joists and the wooden decking material must be ripped up and replaced on the joists to renew the top surface of the deck. This is a labor intensive effort, including the need to dispose of the existing wooden decking material.

Wooden decks are often subject to checking. Wood shrinks as it dries, but if it dries unevenly, the faster-shrinking areas pull apart from the slower-drying ones, creating cracks and splits called “checking.” Exposure to the elements can accelerate the checking process, so that decks are often subject to checking issues within about three years after initial installation.

SUMMARY OF THE INVENTION

The present invention fulfills one or more of these needs in the art by providing a kit of materials to use to rejuvenate or resurface a deck including a plurality of boards with a combined surface area to cover at least 10 square feet, sufficient glue to bond the 10 square feet of boards to an existing deck surface, and brads to help hold the boards down on the existing deck surface during curing of the glue.

Preferably, the boards of the kit of materials have a grooved pattern on a top. The grooved pattern for a board that has a length and two sides includes flat areas at each side, two sets of grooves interiorly of the flat areas and another flat area interiorly between the two sets of grooves.

Preferably, each board has a length and two sides and side edges and the side edges are not tongue-and grooved. Each board may have a transition from the top to each side edge that is radiused.

Each board preferably has end matching in the form of a tongue at one end of each board and a groove at the other end of each board so the boards can be installed with end matching. Preferably, each board has a transition from the top to each end that is radiused.

Preferably, each board has been continuous kiln dried, patterned, reverse grooved, and end matched. A preferred board species is Southern yellow pine. Preferably the boards have had “EcoLife” treatment with a non-metallic preservative and stabilizer system.

The invention can also be considered as a method of rejuvenating an existing deck surface including removing dirt and debris from the existing deck surface. Then boards are installed on top of the existing deck surface by applying glue to undersides of new boards and gluing them onto the existing deck surface. Each new board that is applied interior of an edge of the existing deck surface is end matched with boards adjacent its end and not being joined with tongue and groove to boards adjacent its sides. The glued boards are held in place with brads while the glue sets.

DETAILED DESCRIPTION OF EXAMPLES OF THE INVENTION

The “Deck Rejuvenation System” addresses the problem of rejuvenating a wood deck, as well as freshening decks made of other materials. The first step is to measure the existing deck O (See FIG. 1) to be rejuvenated. If it has any rotten boards, they need to be replaced. Otherwise, it is not necessary to remove the existing decking boards from the sub-structure, which is the deck construction that is located below, and supports the deck boards and railing system. Sub-structure components may include joists and hangers, ledgers, rim joists, beams, posts, anchors and footers.

The kit materials can be made available in either Patio 1 or Patio 2 grade. For a 10′×10′ deck area to be rejuvenated, ten kits that each covers 10 square feet are needed to cover the 100 square feet of the deck. The boards of the new deck surface can be applied unstained or stained. Kits can be made to cover different square footage areas.

The boards of the new deck are solid wood and preferably continuous kiln dried, patterned, reverse-grooved, and end matched. Preferably they have been EcoLife™ treated and dried after treatment. The preferred boards are one half inch thick and 5½ inches wide. Board lengths of two feet are preferred, but other lengths can be substituted. As seen in FIG. 7, with the dimensions just noted, ten boards or pieces 42 will come packaged as a kit 40 to cover 10 square feet of deck. The kit 40 will also include sufficient glue 44 and a set 46 of small 18 gauge brads to help hold the pieces down during the short curing time of the glue. Installation instructions 48 may also be included in the kit. The preferred glue is “Liquid Nails Heavy Duty,” available from Akzo Nobel Paints LLC, 15885 West Sprague Rd., Strongsville, OH 44136 www.liquidnails.com. Other waterproof glues may be used.

Liquid Nails Heavy Duty is a mixture with the product name LN-903 Heavy Duty AHE90312TN0. According to MSDS for Liquid Nails Heavy Duty, it is made of:

Ingredient Name     %
Limestone           ≥25-<50
Kaolin              ≥5-<10
Propane-1,2-diol    ≥1-<3
Crystalline silica, ≥0.3-<1
respirable powder (<10 microns)

As seen in FIG. 5, boards 10 have a grooved pattern on the top that greatly resists checking and helps resist bow and twist. It is believed that the wood in the boards of the preferred embodiment will resist checking for at least eight years, much longer than the conventional three years. The pattern includes a central flat area 12, first and second sets 14 and 16 of grooves and outer flat areas 18 and 20. As can be seen in FIG. 5, a preferred embodiment has seven grooves 50 in each set, but other numbers of grooves can be used, as seen in FIGS. 8-11. Also as seen in FIG. 5, each groove 50 is adjacent a rounded land 52. Flat areas 12, 14, and 18 at the edges and middle of each board are comfortable underfoot. FIG. 5 also shows the sides 13 and 15 of the board as straight and free of tongue and groove features. The transitions from the top of the board to the sides 13 and 15 are radiused, as shown at 56. The radius edge aids draining and prevents splintering. FIG. 5 also shows the grooves 43 on the underside of the board that extend longitudinally along the length of the board and can be used to hold the glue at installation-time. The grooves 43 also help prevent the wood from cupping. The preferred wood for the boards is Southern Yellow Pine. The wood is preferably dried, kiln dried, and then dried again.

When added to the top of an old, existing deck that built with commonly used 5/4×6 decking material, the boards 10 give the deck a new, stronger thickness equivalent to having built the deck out of 2″ by 6″ boards. The ½ “thickness allows the boards of the rejuvenation kit to be used on top of almost any deck without causing issues at door thresholds.

As noted, preferably, the boards have had EcoLife” treatment, which provides an environmentally friendly protection that is expected to prevent rot for over 30 years. EcoLife treatment is available from Viance LLC of Charlotte, North Carolina and is a non-metallic preservative and stabilizer system, offering the natural beauty of real wood combined with advances in weathering protection and fastener performance.

The end-match system on the products as seen in FIG. 6 adds stability to the existing deck and provides the “solid-under-foot” feel of a high quality deck. End match is the result of each board having a tongue 26 at one end and a groove 28 at its other end. At installation, the tongue of one board is inserted into the groove an end-wise adjacent board. The radius edge 27 added above those elements of the end match system gives the joints better drainage and adds a high end look.

As seen in FIG. 7, the product can be marketed in a kit form 40, with ten boards 42 to cover 10 square feet, sufficient glue 44 to bond the 10 square feet of boards to an existing deck surface, brads 46 to help hold the pieces down during curing, and installation instructions 48.

Any exterior deck (or concrete patio) in need of a new great look can be rejuvenated to look brand new and vibrant. This can be easily accomplished with very little time, expense and effort. The expense and time saved over replacing the deck is substantial.

The boards of the “Deck rejuvenation System” can be laid out on a deck any way desired, as seen in FIGS. 1-4. The boards can run in the direction of existing decking pieces as shown in FIG. 1, perpendicular to the original boards of the deck, or at angles in any direction. The boards can be laid in a combination of patterns. The tools needed to install the materials of the kit are a saw, a small hammer or brad gun, safety goggles, and gloves.

To install the new deck surface, first make sure the existing deck is clean and free from dirt and debris and that all rotten boards in the existing deck have been replaced. If a stain color is to be added, it is suggested that the boards be stained at least a day before installation over the existing deck surface and dry in a cool, clean area.

Next the boards 10 are cut to size. The cutting needed may include cuts at other than right angles to accommodate edge configurations, as seen in FIG. 1, where the installation is at a diagonal, so the board ends are cut at 45 degree angles. Other angles may be preferred for other installations. Then the installer applies glue 44 (which is preferably provided in the kit 40) onto the back sides of the boards. Each board has underside grooves 43 which can be loaded with glue, and the glue is preferably applied in a pattern over the bottom of the board 10. The board is then placed on the existing deck surface, with tongues on board ends inserted into grooves on the ends of boards that have been added previously (or the reverse process: a board so its groove receives the tongue of a previously-installed board end). Once the board is in a desired position, the process includes applying the brads 46 by hammering through the board into the existing deck surface to help hold the pieces firmly in place while the glue cures. The installer can drive the small brads all the way in, planning to leave them, or drive them in only partially and leave the top of the brad exposed for easy removal after the glue cures. Once the glue has cured, the brads can be removed if desired. Otherwise, the rejuvenated, beautiful deck is ready for use.

FIGS. 8-11 show the profiles of the ends of other embodiments.
