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

Product Information

Wind-Driven Rains – Seals against rainwater intrusion due to “sideways rain” forced by strong winds. Use for sealing the porous masonry and at the top of the chimney crown. Once the structural integrity of your walls are up to scratch, you can use a waterproof façade cream to create an invisible barrier between the elements and the exterior of your home. This protects your home against driving rain, potential frost damage, and pollutants. Read more about damp proofing outside walls. Treat your internal walls with anti-mould cleaner and salt neutraliser before redecorating to prevent the reappearance of salt deposits and mould 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. Wear appropriate safety wear at all times. Technical data sheets and additional technical informationis available upon request.

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. As Colour Flex Waterproof Paint cures in direct UV light, it is only suitable for use in outdoor areas. How to apply Colour Flex? The damp patches can also be ‘cold spots’ on your wall, as damp patches lose heat 3 times faster than the surrounding wall. 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. Road Salts – Salt tolerant. Hardens surfaces to protect against corrosion due to road salts and deicing chemicals.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!

We follow a detailed, rigorous process to create content that is helpful, factually correct and meets the highest standard of integrity. 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. We have adjusted the formula of this impregnating sealing product to improve application and sealing performance. 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.Damp proof paint isn’t designed for external use – it’s best used internally to protect against damp. 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.

Chemical Spills – Sheds surface water. Resists stains from surface spills, motor oil, grease, and chemical spills. Improves cleaning maintenance. Alternatively, it can be that some areas of your wall are more exposed or more susceptible to letting water in, despite being sound and this can also cause damp patches or a uniformly damp area to form.

Store sealed in a cool place away from direct sunlight.Once opened, use entire contents as soon as possible. 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. 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. 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.
