Mapei Eco Prim PU 1K Turbo (10kg)

One component, solventfree, moisture curing polyurethane primer with very low emission of volatile organic compounds (VOC) for consolidanting and waterproofing cementitious screeds.

WHERE TO USE

• Surface consolidation of cementitious, anhydrite and heating substrates.

• Waterproofing cementitious screeds with a residual humidity content higher than the level recommended for laying parquet

Some application examples

• Consolidating cementitious screeds which are mechanically weak.

• Waterproofing treatment before laying wooden flooring, to prevent moisture damage due to excessive residual humidity in the cementitious screed.

• Anti-dust treatment for cementitious and dry anhydrite screeds with a crumbly surface.

TECHNICAL CHARACTERISTICS Eco Prim PU 1K is a one-component polyurethane primer which hardens with the moisture present in the surrounding air and in the screed. It is low viscosity and, therefore, has a high capacity for penetrating into the porosity of the screeds. Eco Prim PU 1K does not contain solvents and, therefore, is odourless and is not flammable. Eco Prim PU 1K has a very low emission level of volatile organic compounds (EMICODE EC1 R). Because of the total absence of solvents, Eco Prim PU 1K may also be used on sites which are located close to inhabited areas (such as flats, schools, offices, etc.). After application and cure of the resin, the substrate treated with Eco Prim PU 1K becomes more consistent, harder and is resistant to abrasion.

RECOMMENDATIONS

• Do not dilute Eco Prim PU 1K with water or solvents.

• Do not apply Eco Prim PU 1K on wet surfaces or in the presence of rising damp.

• If a cementitious smoothing and levelling compound has to be applied, or if the parquet is to be laid after more than 72 hours (three days), apply Eco Prim PU 1K so that a thin layer remains on the surface. Completely blind this layer with Quartz 1.2 while the primer is still fresh.

• The product is suitable for consolidating heated screeds and anhydrite substrates which cannot be waterproofed. Make sure that these kinds of substrate are dry before applying the primer. • The laying of wooden flooring on substrates treated with Eco Prim PU 1K must be carried out using reactive polyurethane adhesives (such as Ultrabond P990 1K or Ultrabond Eco 955 1K),
