PENOSIL Gaps & Cracks

PENOSIL Gaps & Cracks is acrylic sealant for clean and smooth joints before painting.


Penosil Gaps & Cracks acrylic sealant is the easy way to achieve professional-looking results when filling gaps and cracks around trim prior to painting. Even surfaces with moderate movement can be brush-painted 2 hours after applicatio. You will be saving time by finishing the job faster. Gaps & Cracks acrylic is compatible with most surfaces but due to the large number of paints and varnishes available, we strongly suggest a compatibility test before use.


Gaps & Cracks acrylic is a plasto-elastic, single component, water-based mastic based on acrylic dispersions. Developed for flexibility and crack-proof performance. Gaps & Cracks acrylic will withstand expansion and contraction without cracking or deterioration of its seal.


Gaps & Cracks acrylic provides a long-lasting, durable seal and forms a joint, which will withstand movement by up to 12,5% without cracking or loss of adhesion.
