Elastomeric Coating
A high-build flexible coating with substantial elongation, able to stretch and bridge hairline cracks as a substrate moves.
On an actual building
On facades with live hairline cracking it is the only coating type that keeps working. Its crack-bridging depends entirely on achieving the specified film thickness.
What we most often have to correct
That it bridges cracks at any thickness. Spread thin to cover more area it bridges nothing, and the premium is wasted.
