Which coating is described as covering and hiding surface cracks?

• A. Elastomeric coating
• B. Acrylic coating
• C. Latex paint
• D. Oil-based finish

Answer: (A)

Elastomeric coatings are formulated to be highly flexible and capable of bridging small surface irregularities. Their thick, rubbery film can stretch and contract as the substrate moves with temperature changes and structural settling, allowing the coating to span hairline cracks without cracking itself. This elasticity makes the coating effectively cover and hide cracks, improving appearance and protecting the surface, especially on exterior masonry or stucco where movement and moisture are common. In contrast, acrylic and latex paints are less extensible and tend to show cracks or fail to hide them as well, while oil-based finishes are more brittle and do not bridge cracks effectively. So, for covering and hiding surface cracks, elastomeric coating is the best choice.
