FAQs (Frequently Asked Questions):

Q: Can it stop damp from returning?
A: No. It seals and masks existing damp stains but does not fix the cause of the damp. Always identify and repair the source of the moisture before application.

Q: Can I use it on freshly plastered or wet surfaces?
A: No. Surfaces must be dry to the touch and free from loose plaster, flaking paint, or mould before application.

Q: Is this suitable for exterior use?
A: No. Polycell Damp Seal is designed for indoor use only. For external applications, use a suitable weatherproof treatment.

Q: Do I need to paint over it?
A: While it provides a white finish, it is intended as a base coat. For a uniform decorative look, it should be painted over once dry.

Q: How do I clean up after use?
A: Being an aerosol, there’s minimal cleanup. Any overspray should be wiped immediately with a damp cloth. Always spray in a well-ventilated area and protect surrounding surfaces.
