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

Product Information

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. Store sealed in a cool place away from direct sunlight.Once opened, use entire contents as soon as possible. Our couriers do not deliver on a Saturday or Sunday (or bank holidays) other than by special additional arrangement. 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. The damp patches can also be ‘cold spots’ on your wall, as damp patches lose heat 3 times faster than the surrounding wall.

Microshield Masonry Water Repellent is a single coat liquid water repellent. It is designed primarily for application over large areas by sprayer to impart high quality water repellence to a substrate which will last for 10-15 years. However where waterproofing creams like Microshield Ultraand PermaSEAL Facade Creampenetrate deeper into the surface due to their cream consistency they can give a surface 20-30 years of water resistance in just a single coat. 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. Ultra-Low VOCs – Complies with California VOC regulations. No noxious odor. Safe for applicators and indoor use.Another important factor is that the appearance is not changed by applying the treatment. This is particularly important in older natural stone buildings. The cream leaves no visible or textural change to the surface. What is the difference between damp proof paint and masonry waterproof paint?

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. As Colour Flex Waterproof Paint cures in direct UV light, it is only suitable for use in outdoor areas. How to apply Colour Flex? 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. Road Salts – Salt tolerant. Hardens surfaces to protect against corrosion due to road salts and deicing chemicals. In this case, once you have fixed the issue, you can apply waterproofer as a preventative measure against future damage.Treat your internal walls with anti-mould cleaner and salt neutraliser before redecorating to prevent the reappearance of salt deposits and mould 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. 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! 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.

We follow a detailed, rigorous process to create content that is helpful, factually correct and meets the highest standard of integrity.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. Wear appropriate safety wear at all times. Technical data sheets and additional technical informationis available upon request. Ensure the substrate is clean and dry before application. Unwanted old coatings as well as algae and moss must be removed. If you want to be sure that your salts and mould won’t return, you can apply a waterproof render or fit a mesh membrane to your wall before replastering.
