Unlike most masonry water repellents, Stormseal is the emergency water seal you CAN apply in wet weather. No more waiting for ideal dry conditions. This high-quality brick waterproof sealer is perfect for exterior porous surfaces.

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. Therefore, no risk of the white staining which afflicts solvent-based products.

Water Seal Paint for Brick, Stonework & Concrete

If your external wall has cracks or pointing is letting water in, it is possible that this water can travel to your internal walls. Water ingress can also be a problem for very old walls or walls in poor condition. This means that it can be difficult for homeowners to keep their eternal walls dry and free of penetrating dampness. We have developed this product to make waterproofing exterior brick walls quick and easy.

In the British climate, external walls are constantly being exposed to water from things like rainfall. Stormseal is fully breathable, forming an invisible but impenetrable barrier to moisture. It allows walls to breathe and has an expected lifespan of 3 to 5 years. Stormseal is a multi-substrate brick waterproof sealer compatible with:

  • Most Brick Types
  • Sandstone
  • Limestone
  • Granite
  • Slate
  • Lime Mortar
  • Cement Mortar Joints

Water ingress is very common in most types of brickwork. This is because external surfaces contain a large amount of very small porous voids that draw in moisture. Our brick sealer will ensure your walls are dry at all times. Once applied and dry, water will bead or bounce off the sealed brickwork instead of being absorbed into the external surface.

If you are seeing patches of damp or signs of water penetration, we can help. The Stormseal brick waterproof sealer is very easily applied, by either using a brush or roller. We have a wealth of experience providing damp proofing products to combat rising damp. For more information on waterproofing exterior brick walls, don’t hesitate to contact us.

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.
