Stormdry Masonry Waterproofing Cream (1 Litre) 25 Year BBA Approved Exterior Brick Sealer. Breathable, Colourless Brick, Concrete, Stone, Mortar, Sandstone & Granite Waterproofer

This is amazing stuff. I painted the whole of the lower half of my house with it (the upper half is tiled). I applied this in October 2024 and it was easy to apply with a masonry brush. At the time I thought it was expensive stuff but a few months down the line I can really appreciate the benefits. When I'm outside and I'm watering plants or it's raining, I can see the water just beading off the brickwork. It has provided a thorough water resistant barrier. During the winter in my kitchen, the walls despite having cavity insulation, are usually very cold and condensation would appear on the actual walls when I am cooking. This year the walls remained completely dry because of this product, I'm absolutely certain of this. The house did feel warmer too. I'm delighted with this product and would recommend it to anyone. Update: over a year on and it really works! I live in a terraced house and after the rain I can see a complete difference between my neighbours brickwork and mine. Mine sparkles from rainwater droplets remaining on it, the neighbours is dull and Matt where the bricks have absorbed the droplets. Incredible difference to the warmth of the house inside too.

I'm trying this as I have solid brick walls and an internal wall which is very cold in winter, some small amounts of black mould appearing and blown plaster as well. Inside I have also used the anti-mould paint but decided there may be an underlying cause, namely water ingress via the bricks. It's very easy to apply and brushes clean out in soapy water. The 1 litre tin covered about 3.5m square but I have bricks with grooves on them so they need more paint. I've used a water pistol on the dry surface and it's clearly got some water resistance compared to where I have not applied the waterproofing. As my wall is about 100 years old perhaps it needs a second coat? Gave 4 stars as very expensive.

Easy to apply, clear coat so it matches the rest of the brick work. Unsure if its working or not, but water appears to bead off. I was getting moss growth on bricks that dont get much sunlight, time will tell if it works.

Really does work, not cheap but quality never is.

We had damp ground floor (a tide mark 1 metre high on old masonry) - had builders in who totally gutted house internally and they used this on the outside of the house to help solve our damp issue. To be honest I thought this was just a gimmick initially. Awhile later a damp patch was noticeable on the 1st floor landing when all wallpaper taken off and walls replastered (this issue was probably there all along but had been dwarfed by the ground floor issues). I bought a small tin (1litre) and thought - well -just give it a go. And WOW WOW WOW - this actually works. I am a 53yr old woman and climbed the ladders myself on a dry sunny October day to paint this onto the wall. So pleased I gave this a go, it is definitely the same product my builders used - goes on brickwork with a brush very easily and is white on application so I could see exactly where I had covered. The cream then turns transparent and ultimately disappears completely. I monitored damp patch on internal wall and was amazed, almost immediately it began to fade and now is completely gone. We are going to invest in some more of this in Spring and completely paint the 1st floor masonry. It is just amazing

Just O.K.

Easy to apply with a brush. Too early to say it’s effectiveness on water sealing.

This works very effectively, especially on older masonary and brick.

Dekt goed

Increíble producto,heche éste producto en una segunda vivienda en el campo en la cual tenía algunas humedades,heche el producto por el esterior he interior donde tenía las humedades y después de haber pasado un Año,no han vuelto a salir las humedades.estoy muy contento con el producto.

J'avais des infiltrations a travers un mur de façade et ce produit a stoppé toute rentrée d'eau! Une seule application et je n'ai plus jamais eu de problème! (Depuis novembre 2024). Très satisfait du résultat et aucune différence de teinte sur ma façade.

Prodotto ottimo, funziona benissimo, molto facile da stendere sia a pennello che a rullo e soprattutto non puzza come la maggior parte dei prodotti simili.

Excelente impermeabilizante. Resolví mi problema de filtración. Un 10 para este producto.
