All surfaces must be sound, clean, dry and free of any material which may impair adhesion. Do not apply to shiny surfaces. Scaffolding must be independently tied to allow for uninterrupted application. Any faults in the structure, particularly those which may lead to moisture penetration, must be rectified. Mask around the areas where material is to be applied. Masking tape must be removed before the material has dried out. Beads and expansion joints should be included as required by the substrate and BS standards and carried through all applied materials.
Ecorend W2 Waterproofing Bonding Coat is a two-part system and Part A (powder) should be mixed with Part B (liquid) in the supplied bucket. Mixing fully to a smooth consistency using a paddle mixer. Mix for 2 minutes, allow to stand for 2 minutes then re-mix. This process allows the additives to dissolve and activate. Do not add additional water to the system.
Dampen down any previously completed repairs by misting with clean water immediately before applying ecorend W2 Waterproofing Bonding Coat. Apply by using a trowel and hawk or by brush. The first coat is applied at approx. 1mm to 2mm and allowed to dry but not cure. The second coat of 1mm to 2mm is then applied directly to the first coat ensuring a full barrier is created. Ensure all the surface area is covered completely by W2 Waterproofing Bonding Coat. In some circumstances, a third coat may be required. Minimum thickness of 2mm of ecorend W2 Waterproof Bonding Coat is required. The surface should be left keyed with a brush or stippled to receive the required base coat.
