If you live in an area which experiences significant exposure to driving rain, your home could be at risk of moisture damage. In fact, moisture is the most natural agent responsible for the deterioration of a building’s exterior, with the amount of water deposited on outside walls by driving rain generally larger than any other source, including condensation. However, with just a few simple steps you can ensure that your brick walls are protected against the elements, using Thompson’s Water Seal. Read on to find out more…

Driving rain, defined as rain propelled by driving wind, over time can result in damage being done to your home, including staining, leakage, dimensional change, freeze-thaw damage and much more. As such, it’s important to protect your brickwork with an effective sealant, such as our Thompson’s Water seal – a unique emulsion which stops water penetration in brick, concrete and stone. So, how do you apply it? 

To begin the application process, you first have to clear the surface of dirt and contaminants. If this stage is skipped there is a risk of the Water Seal not adhering properly to the surface – which can cause it to shift and crack. 

To avoid this, we recommend using a stiff wire brush to remove loose debris like dust, moss and cement. Or, for larger surfaces, use a jet washer. The next step involves using our Advanced Brick and Mortar Cleaner to remove any remaining dirt, grime or efflorescence and limescale from the surface, this is again vital to ensure adhesion to the surface. After 15 minutes rinse the cleaner off and let the surface dry.

It is critical that the surface is completely dry before using the Water Seal, as once the product is applied it will seal in any moisture, which could stimulate mould or damp growth. Additionally, by applying to a dry surface you can avoid any cracking or flaking and ensure a good quality and long- lasting finish. 

To apply the seal, simply use a brush, roller or sprayer and apply it to the desired surface in long, smooth strokes – remember, always allow the first coat to dry completely before adding a second. 

By following these simple steps, you will have sealed your brickwork, keeping it protected from rain damage and the issues associated with it.
