With tenacious adhesion and great elastomeric properties, Kleer Structural Sealant serves many purposes, especially filling expansion gaps and nail holes. The non-slump formula can be applied vertically and overhead, and won't run if rained upon. It skins over in 30 minutes to reduce dirt pickup, and can be painted in 1-2 hours, with any acrylic house paint. Provides a full work time of roughly one week.
