Made for repairs and sealing both indoors and outdoors

This silicone sealant is the reliable choice for sealing windows, doors, skylights, pipes, joints, and cracks in walls, floors, and facades. The flexible formula works especially well in areas where movement or temperature changes occur — such as exterior facades, bathrooms, kitchens, and heating systems.

Suitable for DIY enthusiasts and professionals who want a clean, durable seam without specialized tools. The sealant can be applied directly from the tube using a standard caulking gun. More and more people are choosing a flexible silicone sealant over acrylic sealant for outdoor applications due to its higher weather resistance. Limited availability in this version.
