Aquashield PU

Ready-to-use, quick drying, flexible liquid membrane for internal and external waterproofing applications

Product Description

Aquashield PU is a totally solvent-free, ready-to-use, ultra-quick drying, one-component white, synthetic resin based paste in water dispersion. Aquashield PU is easy to apply using a long-haired roller, brush or trowel on horizontal, sloping and vertical surfaces. Aquashield PU dries very quickly to form a flexible membrane without a sticky surface. It is resistant to light pedestrian traffic after just 3 hours and forms an excellent grip with all types of adhesive for laying ceramic, stone material and mosaic of all kinds. The flexible nature of Aquashield PU helps it withstand normal movements caused by expansion and shrinkage of the substrate due to temperature variations and vibration.

Field of Application

To form waterproofing layers without applying ceramic, stone and mosaic coatings in:

· balconies and terraces;

Application Procedure

Preparing the substrate

The substrate to be treated must be mechanically robust and clean. Remove all cement laitance, traces of powder, flaky parts, grease, oil, and form release agents by sandblasting or washing down with a high-pressure water pump. If the substrate to be waterproofed and protected with Aquashield PU is in poor condition, remove the damaged parts manually or mechanical abrasion by using a hydro-demolition system or a hydro-scarified. The last technique, which uses high-pressure water, is recommended because the reinforcement rods are not damaged. The structures that are not subject to vibration could cause small cracks in adjacent concrete. Once the rust has been entirely removed by sandblasting, repair with a pre-blended repairing mortar. Absorbent surfaces to be treated with Aquashield PU must be primed with Seal Primer. Existing floors, which are covered in tiles, must be well bonded to the substrate, and the surface of tiles must be free of substances that could compromise the adhesion of Aquashield PU, such as oil, grease, paint, wax, etc. In order to remove material that could affect the adhesion of Aquashield PU, clean the floor with detergents and water. After this, the surface must be treated with DCI Grip Primer.

Ready to be used.

Applying the product

Aquashield PU must be applied in two layers with a brush or a long-haired roller. Before applying the second layer, wait until the first coat is dry, making sure the product becomes darker with a matt finish. The second layer is applied diagonally to the first one. The final thickness of the two layers of Aquashield PU must be at least 0.8 mm to create a solid, flexible, and continuous film. Ensure there are no interruptions in the film caused by imperfections in the substrate.
