Accepted Answer

Yes. The membrane is designed for internal and external use, and its UV resistance helps it hold up when exposed to sunlight. Proper surface preparation and adhesion are important for best results in either environment.

Question 9

How do I install Polyshield HD step by step?

Accepted Answer

Basic installation steps: (1) Ensure the surface is clean, dry, and free of loose material. (2) Cut the membrane to the required size. (3) Peel back a portion of the backing and apply the membrane to the substrate, pressing firmly to activate the adhesive. (4) Smooth out air pockets with a roller to ensure full adhesion. (5) Seal seams with compatible tape or by overlapping and pressing firmly. (6) For external use, protect exposed edges and joints from abrasion. Always follow surface-specific preparation and seam-adhesion guidance for best performance.

Question 10

What are common use cases or scenarios for Polyshield HD?

Accepted Answer

Use Polyshield HD in basements, cellars, and bathrooms to prevent dampness and water ingress. It can also be applied to external walls or areas where moisture control is critical, such as under slabs or other damp-prone surfaces, to create a reliable moisture barrier.
