Polyurethane 600ml gray liquid Mapeflex PU 50 SL MAPEI

Mapeflex PU 50 SL is a high-quality polyurethane liquid sealant with a low modulus of elasticity, specially designed for sealing horizontal and vertical joints with movements of up to ±25%. The product provides a permanently elastic and waterproof bond that can be painted after hardening. Thanks to its liquid consistency, Mapeflex PU 50 SL is easy to apply and self-leveling in depth, ensuring an aesthetic and clean finish to the joints. It is suitable for internal and external applications and provides excellent adhesion to a wide range of building materials, including concrete, bricks, ceramics, metals, glass, plaster, wood, MDF, PVC and other plastics.

Mapeflex PU 50 SL is characterized by excellent resistance to aging, UV rays, weathering and temperature fluctuations from -40°C to +70°C. The product is chemically neutral, solvent-free and odorless, making it safe for professional use in residential and industrial premises. Curing is controlled and allows movement of the joint up to 25% of its width, while ensuring high strength and elasticity, without the risk of cracking.
