Product Description

Seal up any joint that needs work with the Evo-Stik Intucrylic Intumescent Acrylic Sealant White C20, a strong, high quality sealant made from top-quality acrylic. The sealant won't slump in the joints, even if they are as large as 30 millimetres in size. It is airtight and therefore prevents the transmission of flames or smoke from getting through its tight seal. This product's packaging is designed to make dispensing and using it an accurate and easy experience, thanks to its thin nozzle design. When the sealant dries,it is an unassuming white colour to blend in easily with the rest of the material.
