DUSEAL PS 250 is designed for use as a protection sheet over waterproofing membranes (e.g. DUSEAL FP ) where traditional protection boards prove difficult to install, such as
- Manholes, pipes and the like
- Tunnels, trenches and ducts
- Any structure where shape conformity is important.
METHOD OF APPLICATION
The substrate to be waterproofed / protected should be dry, smooth, and free from dust, dirt, oil, protrusions and cavities. The concrete or metal surface should be primed thoroughly with DUPRIME -Duproof Primer and allow to dry. The drying time depends on the porosity of the substrate and the environmental conditions (approx. 0.5 – 3 hrs.)Install DUSEAL PS 250 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. Allow end lap of 150 mm and side laps of 100 mm or as per code of practice and ensure complete sealing.DUSEAL PS 250 in general can be adhered to various types of substrate (concrete, concrete blocks, bricks, foam concrete, fiber cement board, wood boards and metal substrates) by removing the silicon-based foil from the bottom side. When applied over DUSEAL CXL or DUSEAL FP or DUWRAP tapes ensure the adhering surface is free of dust, grease, oily nature or water to achieve good bonding.
