Extreme Climate ONE COAT water seal stops penetrating damp using the latest fluorocarbon technology to create simply the best performing (100% breathable) brick and stone sealer available today. With a lifespan of up to 10 years and no surface darkening, this formula halts rainwater absorption offering truly exceptional hydrophobic or bead up water repellency. Kingfisher Approved contractors can offer a 10 year re-pointing guarantee, incorporating Extreme Climate, Kingfisher pointing mortar and pointing solution.

Extreme Climate water seal prevents damaging moisture ingress which causes masonry to spall in the freeze / thaw cycle and inhibits moss growth by robbing it of water and nutrients drawn from damp mortar. Using Extreme Climate to dry out a damp wall can also reduce thermal loss by up to 30% because a wet wall is a cold wall and "bleeds" heat to the atmosphere at an accelerated rate.

Drying out with Extreme Climate also reduces the problem of condensation and black mould, which develop on the indoor side of exterior walls when rain saturation cools the wall temperature such that warm moist indoor air condenses on the cold surface. On a related issue, if you have problems with efflorescence or salting which is the unsightly, white staining we see on so many new build walls then Extreme Climate water seal can help by limiting the moisture absorption / evaporation cycle which leaves mineral salts deposited on the surface. Please call us for detailed advice on treating efflorescence.

Extreme Climate water seal also helps to keep buildings clean by forming an effective barrier against airborne dirt and other contaminants, which would otherwise be dissolved by rainwater and leech into the substrate where they inevitably stain the surface.

Finally, if you have previously applied cheaper alternatives which may have worked for a year or less (or not at all!) then this product is for you. Save hundreds or even thousands of pounds on remedial re-pointing, re-plastering and re-decoration by treating your external walls, facades and gables with Extreme Climate, the ultimate water seal for your masonry in extreme weather.

I used extreme climate on a property built of granite. We suffered damp patches internally I have to say the results are amazing and plan to use it again on other parts of the building.

I purchased a sample of the Extreme Climate to test on my 1907 sandstone built house. The sandstone is prous and I'm getting water penetration around the chimney where the cavity is rubble-filled. On a lower part of the house, the solution seems to work well and so I'm intending to buy sufficient to treat both chimney stacks. I can't vouch for the longevity, of course, as yet. Ask me in 10 years time.
