The surface to be waterproofed should be dry, smooth, free from dust, dirt, protrusions and cavities.
The surface should be primed thoroughly with Nuraflux Primer and allow to dry. The drying time depends on the porosity of the substrate and the environmental conditions (approx. 0.5 - 3 hrs.)
Apply gussets to high stress areas such as internal and external corners.
Install Nuraseal by removing the release foil and unrolling the membrane along with it. The membrane especially at the overlaps should be firmly pressed down from the center to the sides, to ensure a good seal and to remove entrapped air.
Top edges overflashed or secured to ensure there are no loose or uncovered edges above or below ground level.
Install drainage and protection boards prior to backfilling.
