Aqua Sil Advance

Waterproofing, sound reducing and anti-fracture membrane

Product Description

Aquaseal Advanced is a one-part, trowel applied, elastomeric waterproofing, crack and sound isolation membrane and setting adhesive. Use Aquaseal Advanced as a waterproofing, crack, and sound isolation membrane over properly prepared concrete; structurally-sound, exterior grade plywood, cementitious backer board, and existing well-bonded vinyl or ceramic tile prior to the installation of ceramic or stone tile. Aquaseal Advanced may be used with gypsum based underlayments in dry, above grade installations with minimum compressive strengths of 25 MPa.

Field of Application

For waterproofing and protecting:

· flat roofs;

· paving slabs;

· cupolas and curved roofs.

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 Aquaseal Advanced 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 Aquaseal Advanced 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 Aquaseal Advanced, such as oil, grease, paint, wax, etc. In order to remove material that could affect the adhesion of Aquaseal Advanced, 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

Aquaseal Advanced 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 Aquaseal Advanced 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.
