Masonry Water Seals

Why coat the exterior walls of our house with Kingfisher water seal products?

Extreme Climate - masonry water repellent

Applying water seal treatments to your exterior masonry and stonework will benefit your home in a number of ways. The most important among these include:

Protection against structural damage to your brickwork

Over time natural weathering gradually degrades the face of most bricks, stone and mortar joints. Once the surface is wet and holding water, it becomes vulnerable to the freeze/thaw cycle and cracks often form in bricks and pointing leading to further moisture penetration and more retained moisture in the wall. Such "porous" walls readily soak in water which eventually penetrates right through to the interior walls where it typically shows up as damp patches on your plaster after heavy rain. By applying a kingfisher water seal you will protect your building from weathering and the destructive effects of this "lateral" penetrating damp.

Reduce the effects of moulds, mosses, weathering and efflorescence on your masonry

These treatments not only benefit your building structurally but they can also greatly improve your homes aesthetic appeal by inhibiting the growth of mosses & green mould, which deprived of moisture grow much less aggressively.

In addition, our products have been used to successfully treat the unsightly efflorescent white salts or "white fur" staining which often appears on brick-built properties. (Salts are naturally present in sand, cement, and the clay used in brick manufacture). Brick Efflorescence occurs as water soaks into the bricks and mortar joints and then evaporates out carrying salt and other minerals to the surface, leaving the unsightly white residue or "fur". Water seal treatments such as Extreme Climate and Superseal prevent this by stopping the water from penetrating the surface of the bricks in the first place. If Efflorescence has already occurred use our Eco-Brick Cleaner to remove them before using a water seal.

reduce home and house heat loss with masonry water seal

Protect your home from heat loss through your walls

Kingfisher's Next Generation Waterseal treatment, "Extreme Climate" can also reduce heat loss in some walls by up to 30%. Thermal heat loss due to water penetration arises because a wet wall is a cold wall - (think of standing on a windy hillside in soaking wet clothing compared to being in a dry, waterproof jacket!). Your home is exactly the same - energy from your heating is effectively being drawn or sapped into the cold, damp wall and wasted in energy transfer as your heating works to evaporate this moisture. By reducing the moisture levels within the walls of your property, water seal treatment reduces this home heat loss and as a result can significantly reduce both your energy costs and your carbon foot print.
