The present disclosure generally relates to formulations for coating and sculpting applications. More specifically, the present disclosure provides latex-based formulations suitable to provide coatings, sculptable forms, castings, and fillers.
In many coating applications, it is desirable for coatings to exhibit high levels of adhesion to surfaces that do not include adhesive properties, such as metal surfaces. A combination of high adhesive properties and low density enables coatings with substantial thicknesses to adhere to different surfaces, including inclined surfaces and vertical surfaces. However, when the thickness of a coating exceeds approximately 0.25 inches, the coating often will not adhere to surfaces. For example, as latex coatings must completely dry on surfaces, multiple layers of latex coatings can be required to successfully adhere to and be cured on surfaces. Additionally, some coatings cause surfaces to crack. To solve the problem of surface cracking, in the past, polymer microparticles have been added to cement coatings to improve the resilience and resistance of surfaces. However, cement coatings including polymer microparticles can be relatively brittle and can still create cracks under mechanical stress.
Embodiments of the present disclosure may provide a method of forming and applying a latex-based formulation to a surface. The latex-based formulation may include a wet mixture and a dry mixture to form the formulation. The method may provide the step of blending the wet mixture and the dry mixture. The wet mixture may include a plurality of latex polymer microparticles, and the dry mixture may include at least one absorbent material. The method may further provide the step of applying at least one layer of the latex-based formulation to the surface. The method may provide the step of curing the surface where the latex-based formulation has been applied, thereby reducing cracking and shrinkage of the surface.

The surface may be coated with water prior to or after blending the wet mixture and the dry mixture. Further, the at least one absorbent material may include an inorganic material that may be selected from the group that may include cellulose, Kaolin clay, vermiculite, corn cob, talc, volcanic ash, peat, and sawdust. The at least one absorbent material may be an expanded volcanic mineral treated with a surfactant. The latex-based formulation may fill gaps in the surface.
