Two component, polyurethane-based, solvent-free liquid waterproofing material for especially potable water tanks.
Preparation of Substrate
The application surface must be durable, dry, clean and clean off materials which prevent bonding, such as dust, oil, rust and remove loose pieces. POLIXA 2 results foaming when applied to wet surfaces. For this reason, EPOX PR 300 should be used on concrete surfaces as a primer.
Application temperature should be beetwen+ 5°C to + 30°C. Component B, hardener, is slowly poured into Component A, main component, under the low speed drill and continue mixing until obtaining a homogenous mixture without any agglomerate (approximately 3-4 minutes). The mixture must be consumed within 30 - 45 minutes; later it cannot be applied due to jelling. Mixture should be applied with a brush or roller as 2 or 3 layers. Brush application direction in each layer must be perpendicular to each other. Each coat must be applied 6 hours later than the preceding coat. If this interval exceeds 24 hours, the first coat must be sandpapered prior to the application of the second coat. After the application the surface must be protected from water, rain for at least 6 - 8 hours. Dry sand should be added on POLIXA 2 while floor coating.
Minimum 0,600 kg/m² for each coat. Recommended at least 2 layers application.
A component: 5 kg resin + B component: 1 kg hardener = 6 kg set in metal pail.
