This ensures that the interior is protected from severe weather and penetrating damp, but any residual moisture or water vapour is still able to escape. We follow a detailed, rigorous process to create content that is helpful, factually correct and meets the highest standard of integrity.

Water repellent façade creams will last between 20-30 years depending on weathering. As a result, you can expect to wait at least 20 years before having to reapply a waterproof coating. ECO-FRIENDLY – Environment-friendly, non-toxic, non-flammable, non-corrosive, and non-hazardous. Ultra-low VOCs with no noxious odors or fumes. Not harmful to plants, grass, or aquatic life.

This is a problem because they can act as a bridge for damp that has accumulated in an external wall to travel across the cavity to the internal wall, again creating a damp or cold patch.Ensure the substrate is clean and dry before application. Unwanted old coatings as well as algae and moss must be removed. Damp proof paint isn’t designed for external use – it’s best used internally to protect against damp. Once you give those cleaners some time to set in, you have to rinse the surface and rinse it well. This step is where a power washer is helpful. It will blast the remaining cleaner and contaminants right off, cleaning the surface and clearing the way. Afterward, you may want to apply a sealer.

Treat your internal walls with anti-mould cleaner and salt neutraliser before redecorating to prevent the reappearance of salt deposits and mould Standard delivery is always free except to the Scottish Highlands & Islands, Northern Ireland & other UK offshore Islands.

If your plaster is sound, once the walls have dried out you should be able to treat them with a salt neutraliser or an anti-mould cleaner to get rid of any salt deposits or mould spots before redecorating.
