POLYFLEX® N is a two part acrylic modified cementitious coating for protecting concrete structures against water, vapor, ingress of chloride ions, attacks of acidic gases and alkalis. It cures to form a tough flexible coating having excellent waterproofing properties. Polyflex is a blend of cement, selected fillers, polymers and graded silica sand which is in the powder form. The liquid contains acrylic copolymers and wetting agent
The surface must be structurally sound and free of oil, grease, dust and other contaminants which will affect the bonding.
Polyflex N is supplied in two pre-measured parts which just requires on site mixing. Do not mix more material than that can be used within the pot life. Part mixing can be carried out by mixing 3 parts of powder with 1 part of liquid.Pour the liquid into a suitable container and slowly add the powder to the liquid. Mix the contents
It is recommended to apply Polyflex N in two coats to provide a minimum thickness of 2mm. Each coat shall be applied @1.85 kg/m2 which will give a dry film thickness of 1mm. The coating can be applied with a stiff brush or by an airless spray of nozzle size of 3-4mm and a pressure of 6-7 bar. After the application of the first coat and whilst the coating is still wet, embed a glass fibre mesh at all corners and other joints for added reinforcement.
