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.).
Nuraply 3PT is adhered to the substrate by heat fusing the base of the sheet as it is rolled up the substrate.
All lap joints are welded as a separate process. As this step is vital, a three pass method is used so that the quality of the weld is checked during the process.
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.
