TL;DR
Elastomeric coating is a high-build acrylic or silicone paint that cures into a thick rubber-like membrane — commonly 10 to 20 dry mils, several times thicker than house paint — able to stretch across hairline cracks and bridge them as the substrate moves. Painters apply it to stucco, masonry, and concrete walls; roofers use related formulations as reflective flat-roof coatings.
What it means
Elastomeric coating is a high-build acrylic or silicone paint that cures into a thick rubber-like membrane — commonly 10 to 20 dry mils, several times thicker than house paint — able to stretch across hairline cracks and bridge them as the substrate moves. Painters apply it to stucco, masonry, and concrete walls; roofers use related formulations as reflective flat-roof coatings. It needs sound, dry substrate and two heavy coats; over damp masonry it can trap moisture and blister.
