Sikaflex Self-Leveling Sealant
Polyurethane concrete crack filler
A flexible, paintable latex caulk engineered to seal the perimeter gap between window casings and drywall — the wall cavity bypass that standard weatherstripping cannot reach. Remains flexible through seasonal expansion and contraction without cracking, and accepts standard interior paint for a completely invisible finish on all interior trim surfaces.
