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. 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. Wear appropriate safety wear at all times. Technical data sheets and additional technical informationis available upon request. Treat your internal walls with anti-mould cleaner and salt neutraliser before redecorating to prevent the reappearance of salt deposits and mould 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.

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? 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. 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.We have adjusted the formula of this impregnating sealing product to improve application and sealing performance.

As Colour Flex Waterproof Paint cures in direct UV light, it is only suitable for use in outdoor areas. How to apply Colour Flex? 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. Dryseal waterproofer is both an effective and breathable formulation, and so we can recommend it for waterproofing your outside walls. 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. A waterproofer is usually only used as a solution for sound external walls that are exposed to enough rainfall that they just become damp.Standard delivery is always free except to the Scottish Highlands & Islands, Northern Ireland & other UK offshore Islands. 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.

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. 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.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. 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. 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. 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.
