Unlike most masonry water repellents, Stormseal is the emergency water seal you CAN apply in wet weather. No more waiting for ideal dry conditions, Stormseal's innovative formula quickly seals damp walls when you need it most, during prolonged wet and stormy weather. Stormseal is water-based so there is no reaction with damp masonry and therefore no risk of the white staining which afflicts solvent-based products.

Stormseal is fully breathable, forming an invisible but impenetrable barrier to moisture, with expected lifespan of 3 to 5 years. Stormseal is a multi-substrate water repellent compatible with; most brick types, sandstone, limestone, granite, slate, lime mortar and cement mortar joints.

Wish I'd found this earlier!

With the extreme weather we had in the early part of this year and December of last, I had a high number of customers who were suffering from water ingress. A few of these were down to penetrating damp along. As the walls were saturated we couldnt use solvent based repellents. With Storm Seals wet on wet application we were able to apply the treatment with quick results. On two properties we revisited within 48 hours, Water was beading on the surface. Wish Id found this product earlier! With regards to deliveries, My last order was extremely quick, same day.

Stopped Damp in its tracks

Due to the terrible weather we have had in cumbria, some houses were subjected to flooding and for those on higher ground like myself, it was driving penetrating damp that was the issue. After two coats of stormseal on my gable wall, applied during rain spells, the water began to bead on the surface and after a couple days, dampness stopped coming through the wall. Incredible product, does exactly what it says it would do.
