A variety of interior applied masonry paints are available. Some of these have been tested by the AEERL laboratory at the U.S. EPA. Results of these tests are given in a paper presented at a Symposium on Radon Reduction Technology.39... 

In addition to the use of dry acrylic powders in cement mortars, other typical uses for these modifiers are in cement toppings, ceramic tile adhesives, ceramic tile grouts, white masonry paints and cement block fillers. It is obvious that these compounds are more convenient to use with the simple addition of water, than those compounds requiring the addition of a latex emulsion. As improvements are made in these dry powders, there will be more emphasis on this type of compound. At the present time, the dry powder acrylics are more costly than the latex emulsions on a dry solids basis.

By incorporation of infrared (IR)-reflective metallic pigments into masonry paints, the heat emission from buildings can be efficiently reduced [1]. As a result the wall will cool down less at night, which prevents the formation of dew on the surface. Thus, corrosion by humidity is minimized as well as soiling due to humidity-induced growth of microorganisms. 

Masonry paint n. An alkali-resistant coating, usually a latex paint, used for masonry substrates. 

Using various model dispersions, acrylic/styrene and pure acrylic copolymer dispersion binders for masonry paints were investigated by studying the way in which chemically different monomers affected the film properties and those of formulated paints. The test methods used were for water resistance, water vapour transmission, tensile properties, colour variation, UV transmittance, UV stability, artificial weathering and weathering-induced chalking. 12 refs. 

The choice of binder which permits the formulation of a solventless and odourless paint is discussed, with respect to performance requirements. These requirements can be achieved by reducing the minimum film forming temperature of the binder and neutralising with an odourless base. A description is given of comparative tests made on masonry paints based on acrylic emulsions having different minimum film forming temperatures and neutralisation. Differences and similarities between such acrylic emulsions are discussed. Typical commercialised products of similar particle size were used from the acrylic/styrenes and pure acrylics. The hard monomers of the binders used were methyl methacrylate or styrene, and the soft monomer in the binders was butyl acrylate. Experiments were made with mat masonry paints in the PVC range of 40-60%. 6 refs. 

Acrylic based polymers used in masonry paints can be broken down into two general classes ... 

The main requirements of masonry paints are good water resistance, exterior durability, yellowing, dirt pick-up resistance and good adhesion to a variety of substrates.
