SIKADUR庐-20 CRACK SEAL | LOW VISCOSITY SEMI-ELASTIC EPOXY CRACK SEALER | 2-COMPONENT CONCRETE CRACK REPAIR & LEAKAGE SEALING EPOXY RESIN

Sikadur®-20 Crack Seal is a premium solvent-free, two-component low viscosity semi-elastic epoxy resin specially formulated for sealing non-structural cracks, cavities, and joints in concrete. Its excellent penetration ability allows it to flow deeply into fine cracks, creating a durable and watertight seal that helps prevent further water ingress before waterproofing works. It is suitable for both dry and damp concrete surfaces, making it a reliable solution for repair and maintenance projects.

Designed for contractors and professional applicators, Sikadur®-20 Crack Seal offers high adhesive strength with no shrinkage after curing, ensuring long-lasting crack sealing performance. The semi-elastic epoxy formulation accommodates minor movement while maintaining a strong bond to concrete substrates. It is commonly used for repairing cracks in concrete roofs, balconies, wet areas, swimming pools, concrete decks, and floor tile joints affected by leakage.

Easy to mix with a simple 1:1 ratio, Sikadur®-20 Crack Seal is ideal for sealing cracks up to 10 mm wide before applying waterproofing systems or carrying out finishing works. It is widely trusted in residential, commercial, and industrial construction projects throughout Malaysia.
