Question 3

What are Styrene-butadiene coatings and how are they commonly used?

Answer 3

​ These water-based coatings are formulated using styrene and butadiene, producing a rubber-like film. They resist alkali well and are permeable to water vapor. Styrene-butadiene coatings are used as exterior fillers over porous concrete surfaces. Some formulations are used on interior masonry, plaster, and gypsum wallboard, producing a washable film that resists abrasion. They generally are not used on wood.
