Using this formulation, a process was then developed to produce lightweight wallboard. The surfaces of the foamed board were compressed or densified to produce relatively high smoothness. Paper sheets normally used to cover wallboard were applied to both sides simultaneously with the compression action. The excellent adhesive character of the sulfur produced tight bonding, and no special treatment of the paper was required. 

Quite frequently, copolymerization is used to optimize the properties of polyacrylates. For example, copolymers of ethyl acrylate with methyl acrylate provide the required hardness and strength, while small amounts of comonomers with hydroxyl, carboxyl, amine, and amide functionalities are used to produce high-quality latex paints for wood, wallboard, and masonry in homes. These functionalities provide the adhesion and thermosetting capabilities required in these applications. Monomers with the desired functional groups most often used in copolymerization with acrylates are shown in Table 15.8. 

With regards to the connection of wallboards to masonries, a number of studies have experimentally shown that, besides the adhesion by resin, a further mechanical anchoring is recommended, which can be obtained with composite or metal material.

Coatings and construction products - Gelling-grade clays are used as thickeners/stabilizers in paints, asphaltic coatings, adhesives, mastics, mortars, and cements. There is also limited use as a partial asbestos replacement in wallboard and certain cements, where long-needle products are preferred. 

Bathrooms - Polyvinyl acetate sealants, acrylie emulsion sealants and silieone rubber sealants are all used as bath-tub caulks and for wall tile and wallboard joints. Polyvinyl acetate and acrylic emulsion sealants are easier to apply and clean up, and are lower cost than silicone sealants. The silieone sealants form stronger adhesive bonds and have better long term durability.
