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.

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.

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. Road Salts – Salt tolerant. Hardens surfaces to protect against corrosion due to road salts and deicing chemicals.

Stormdry only requires one coat, and we found that it was touch-dry after a few hours and water repellent after two days and largely water resistant after 28 days. In this case, once you have fixed the issue, you can apply waterproofer as a preventative measure against future damage. 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. 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 one of the best ways to keep your masonry waterproof The Consequences of External DampOnce 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. The damp patches can also be ‘cold spots’ on your wall, as damp patches lose heat 3 times faster than the surrounding wall. Chemical Spills – Sheds surface water. Resists stains from surface spills, motor oil, grease, and chemical spills. Improves cleaning maintenance. 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. 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!
