TECHNICAL DATA SHEET 1 component adhesion and moisture primer based on polyurethane Strengthens powdery and brittle, absorbent subfloors Improves the adhesion of parquet adhesive to the subfloor Allows to quickly continue working: parquet flooring can already be laid after 1 hour Ready to use Solvent-free Does not contain VOCs Not flammable Suitable as an adhesion primer on cementitious subfloors (screed) that are powdery and brittle. Suitable as an adhesion primer on dry anhydrite subfloors (<0.5% residual moisture). Suitbale as an adhesion primer for ceramic tiles. Suitable as an adhesion primer for underfloor heating, if the subfloor is dry. Suitable as a moisture barrier for cementitious subfloors with a residual moisture of up to 4% (measured with carbide meter). Suitable as an adhesion primer and moisture barrier for leveling mortar. It is recommended to sand in the primer. Can be used as a synthetic repair mortar for small cracks and cracks (≤ 5 mm) in the screed when mixed with fine, dry sand. TECHNICAL CHARACTERISTICS* Aspect Curing system Cures by moisture in air and substrate Viscosity (Brookfield) Processing temperature Consumption as an adhesion primer Consumption as a moisture barrier Floor laying Completely cured Shelf life, in original closed packing in a dry, cool place free of frost with temperatures above 10°C PACKING Canister of 10 liters - 50 canisters / pallet METHOD OF USE Substrate • The surface to be treated (absorbent and insensitive to moisture) must be clean and free from any substance that can come loose or tear. • If the latter is the case, the necessary repairs can be carried out with synthetic mortar prepared with Primer PU Turbo and dried fine sand (0.3 - 0.5 mm). • Fine cracks in the substrate (max. 5 mm) can be repaired with synthetic mortar, by mixing Primer PU Turbo and dried fine sand (primer/sand ratio 1:6). To improve the adhesion of the mortar on powdery surfaces, a layer of pure Primer PU This technical data sheet replaces all previous editions.

Application (when used as an adhesion primer) • Apply 1 uniform layer of Primer PU Turbo to the subfloor with a roller or a brush. The subfloor must be sufficiently saturated. • In case of particularly porous and absorbent surfaces, a second coat of Primer PU Turbo may be required, with an interval of at least 1 hour (within max. 24 hours). • When applied correctly, a uniform film forms, improving the adhesion of the parquet adhesive to the surface of the subfloor. • Avoid mirroring by over-applying the primer. This is detrimental to the adhesion. • Close the canister tightly after use. Do not...
