Use fields

Horizontal sealing of joints in industrial flooring, even in the presence of chemical attacks and stresses from average-heavy traffic. Vertical sealing of joints in concrete works and products.

Preparation of supports

The application and containment surfaces (joint walls) should be clean, dry, conveniently prepared and adequately resistant: free from dust, grease, soiling, crumbling and/or non-adhering parts and dry. The application surfaces must also be preliminarily treated with PROTECH FLEX PRIMER.

Use method

Add component B to component A taking care to pick up all the material contained in the packs, mix thoroughly with a mixer at a low number of revolutions, until a perfectly homogeneous mix is obtained; add the required load amount (component C) continue to mix until a perfectly homogeneous mixture is obtained, indicated by the uniform colour of the mixture. Apply the product mixed by trowelling or with extrusion guns.
Do not apply with temperatures below + 5°C or higher than + 35°C and in the presence of surface stagnant water.
