BRICK WATERPROOFING

Masonry Waterproofing Is Paramount

In short, bricks and mortar aren’t 100% waterproof. Even modern homes that are built with cavity walls and largely impermeable materials can still be affected by penetrating damp (water coming in from the outside). Damp and excess moisture within brick and stonework can lead to internal damage and the dreaded black mold.

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.

Whether you’ve already seen evidence of penetrating damp or are looking to reduce the risk, it’s important to use a trusted product when waterproofing brickwork. The key to protecting your home against penetrating damp is don’t ignore the root cause. Building faults, cracks, and faulty mortar will need to be repaired before you can go ahead with any brick waterproofing. Find out how to repair cracks in walls.

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.

Please check with a pro like us if you are unsure whether the water repellent is suitable for your type of stone or masonry. Some substrates will not fully absorb the active ingredients if they are water impermeable themselves. It is always advisable to apply a small amount to an inconspicuous area to test compatibility.

Masonry waterproofing creams are ideal for older buildings. Rain is blocked but water vapor is able to pass through allowing the building to breathe as intended during construction.

This ensures that the interior is protected from severe weather and penetrating damp, but any residual moisture or water vapor is still able to escape.

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. Damp proof paint isn’t designed for external use – it’s best used internally to protect against damp. Damp proof paint isn’t transparent – it’s either white, black or grey whereas waterproof masonry creams dry transparent. Damp proof paint isn’t permeable so doesn’t allow for walls to breathe.
