Product Information

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. Ultra-Low VOCs – Complies with California VOC regulations. No noxious odor. Safe for applicators and indoor use. 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.

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. 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. 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. Wear appropriate safety wear at all times.

Protecting your Walls and Solving Common Problems Caused by Damp and Moisture in the Home

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. 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. We have adjusted the formula of this impregnating sealing product to improve application and sealing performance. In this case, once you have fixed the issue, you can apply waterproofer as a preventative measure against future damage. Chemical Spills – Sheds surface water. Resists stains from surface spills, motor oil, grease, and chemical spills. Improves cleaning maintenance.

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. 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. 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.Dryseal waterproofer is both an effective and breathable formulation, and so we can recommend it for waterproofing your outside walls. Damp proof paint isn’t designed for external use – it’s best used internally to protect against damp. Ensure the substrate is clean and dry before application. Unwanted old coatings as well as algae and moss must be removed. 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.

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.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. Dryseal waterproofer is one of the best ways to keep your masonry waterproof The Consequences of External Damp
