About this deal

Ultra-Low VOCs – Complies with California VOC regulations. No noxious odor. Safe for applicators and indoor use. Dryseal waterproofer is one of the best ways to keep your masonry waterproof The Consequences of External Damp

The rule of thumb is, as long as the substrate is porous you can use LastiSeal. You can even use it for sealing fibrous wood! Road Salts – Salt tolerant. Hardens surfaces to protect against corrosion due to road salts and deicing chemicals. 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 have adjusted the formula of this impregnating sealing product to improve application and sealing performance.

Recommended

Ensure the substrate is clean and dry before application. Unwanted old coatings as well as algae and moss must be removed. 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.

Our couriers do not deliver on a Saturday or Sunday (or bank holidays) other than by special additional arrangement. A waterproofer is usually only used as a solution for sound external walls that are exposed to enough rainfall that they just become damp. In this case, once you have fixed the issue, you can apply waterproofer as a preventative measure against future damage. 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.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. Safe for use indoors and outdoors. Long term, the pollutants in the atmosphere and in driving rain, and storms can affect your home in a number of more serious ways: corrosion, growth of algae and lichen on the walls, loss of structural integrity and damage to timber elements. These are all major concerns, which require immediate attention. There are a few reasons why your masonry may have faults and each of these causes will have its own solution, which we will discuss here.
