Raincheck Water Seal 5 Litre - Breathable, Colourless Waterproofer for Brick, Stone, Mortar & Concrete

Product Information

Damp proof paint isn’t designed for external use – it’s best used internally to protect against damp. When your external walls are exposed to a water source such as rain, this water can enter your masonry, in some cases travelling laterally from your external walls to your internal walls. Dryseal waterproofer is one of the best ways to keep your masonry waterproof The Consequences of External Damp

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. Ensure the substrate is clean and dry before application. Unwanted old coatings as well as algae and moss must be removed. Do not allow any sealer to simply dry on the surface, it should all have been absorbed into the treated surface or be removed (where present) after 20-30 minutes. 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.A waterproofer is usually only used as a solution for sound external walls that are exposed to enough rainfall that they just become damp. Dryseal waterproofer is both an effective and breathable formulation, and so we can recommend it for waterproofing your outside walls.

Standard delivery is always free except to the Scottish Highlands & Islands, Northern Ireland & other UK offshore Islands. 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.Paintable – Suitable as a primer before the use of adhesive, epoxy, and acrylic concrete paints. It does much more than the common primers by waterproofing the substrate and reducing water vapor transmission, helping to extend the life of paints and clear coatings. 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. When applied to a sufficiently porous surface, the sealer does not change surface aesthetics or surface friction. It is not intended to bead surface water, but characteristically sheds surface water greatly improving drying time. We have adjusted the formula of this impregnating sealing product to improve application and sealing performance.
