Elastomeric Coating provides a long-lastingWaterproof Coating

Exterior masonry walls—particularly ones that are weathered—have long represented one of the most difficult maintenance challenges for the contractor, the painter, and the waterproofer alike.

Most typical exterior surfaces can be successfully protected and maintained by the regular applications of high quality conventional acrylic latex paints. But even the best paints often tend to split and fail when they have been applied over the surface cracks that develop as masonry ages

A Better Alternative: Elastomeric Wall Coatings 

The construction chemical industry has known about the limitations of traditional paints on masonry. For almost that long, the industry has been searching for better alternatives. Early attempts to solve the cracking problem, involved formulating coatings with polymers not generally used in conventional paints. Many of these experimental systems provided acceptable service as dirt-resistant coatings.

Unfortunately, virtually all of the polymers tested formed hard films that were too rigid to accommodate the temperature-related fluctuation in the dimensions of the cracks. Inevitably, coatings based on these hard polymers fractured, exposing the masonry to the elements once again.

Recognizing that hard binders were not the answer, the industry turned to "softer'' polymers with much lower glass transition temperatures. Many of the products investigated were already seeing use as binders for caulks and sealants. Because they had low glass transition temperatures, they furnished excellent elasticity and flexibility over a wide range of temperatures.

ADVANTAGES:

Instead of depending on a separate, external component to impart flexibility to the film, 100% acrylic elastomeric polymers derive elasticity from a unique combination of special composition, molecular weight, and crosslinking. As a result, they retain flexibility over periods of time. Moreover, formulations based on the 100% acrylic elastomeric polymers exhibit their elastomeric properties over a broad range of temperatures. Thus, the performance of waterborne coatings based on the acrylic elastomerics remains consistently outstanding under all conditions.

In comparing the different types of binders in other areas of performance, the 100% acrylic binders have a significant edge over styrenated products in the area of ultraviolet stabiiity, over viny! acetate products in the area of hydrolysis resistance, and over both chemistries in the area of dirt pick-up resistance. As a result, on extended exposure, waterborne acrylic coatings are more resistant to chalking and do not yellow as do styrenated products. They are not as vulnerable to damage from ambient moisture as acetate-based systems, and they remain cleaner than both types of non-acrylic systems.
