Coo-Var Dampshield

Surface Preparation

Concrete surfaces must be prepared by scarifying, vacuum shot-blasting, planing or other suitable method. All traces of concrete hardeners or other contaminants must be removed. The surface must be thoroughly vacuumed to remove concrete dust and then protect against further contamination by suitable means. Surfaces must be free from liquid, water, and the atmosphere must not be condensing.

Mixing Instructions

Mix the contents of the hardener component with the base thoroughly using a slow speed power stirrer.

Application Conditions

As dictated by normal good painting practice. Do not apply if the temperature is likely to drop below 10 °C during application or during the drying process.

Remarks

The system is selected on the basis of hygrometer readings in accordance with BS 8203. The number of coats to be applied is chosen in accordance with the following table. Relative Coating thickness Humidity Reading % 75 – 85 1 coat @ 230 mic 85 – 92 2 coats @ 230 mic / coat 92 – 97 3 coats @ 230 mic / coat When laid onto a concrete surface where there is no damp-proof membrane (DPM) or where damage may have rendered the DPM ineffective, due consideration must be given to the possible presence of hydrostatic pressure, and the consequences of creating a barrier layer resulting in the pressure / water flow being directed elsewhere.
