Expanding Foam Filler - White

While it can be used to fill gaps around UPVC, always test in a small, inconspicuous area first, as some plastics may react with the foam's components. Ensure proper ventilation.

Curing time varies depending on temperature, humidity, and the depth of the application. Typically, it is tack-free within 10-20 minutes and can be cut or sanded after 4-8 hours, but full curing may take up to 24 hours.

Yes, once fully cured, the foam can be sanded smooth and painted with most standard interior or exterior paints. Ensure the surface is clean and dry before painting.

The cured foam itself is water-resistant, but it is not fully waterproof. For applications requiring complete water submersion or constant exposure, additional protective coatings may be necessary.

If there is remaining product, carefully clean the nozzle according to the manufacturer's instructions and reattach the plastic cap. Store the can upright in a cool, dry place, away from heat sources and direct sunlight. It's best to use the entire can in one application if possible.

The foam is a standard white color and is designed to be paintable. While it provides a neutral base, slight color variations may occur when painted over depending on the paint used. A test patch is recommended.

Ensure the can was shaken vigorously before use and is at the recommended temperature (check product label). Lightly moisten the substrate for better adhesion and expansion.

Fill gaps only to about one-third of their depth. Ensure proper temperature conditions during application and curing. Avoid over-shaking the can.

Apply masking tape around the edges of the area to be filled before application. Clean uncured foam immediately with a suitable solvent cleaner.

Use a sharp, long-bladed knife for cutting. Ensure the foam has fully cured before attempting to sand. For very hard cured foam, a rasp or coarse sandpaper might be necessary.
