Stormdry Masonry Waterproofing Cream (5 Litre) 25 Year BBA Approved Exterior Brick Sealer. Breathable, Colourless Brick, Concrete, Stone, Mortar, Sandstone & Granite Waterproofer

I recently applied Stormdry Masonry Waterproofing Cream to my home’s exterior sand stone walls, and the results have been outstanding. The cream’s thick consistency made application straightforward, adhering well without dripping. After curing, water beads off the surface, indicating effective water repellency. One of the standout features is its breathability; it prevents water ingress while allowing moisture within the walls to escape, reducing the risk of damp-related issues. Additionally, the product is BBA-approved, offering peace of mind regarding its durability and performance. A slight darkening of the brick was noticeable immediately after application, but this faded over time, returning the bricks to their original appearance. It’s worth noting that proper surface preparation is crucial; cleaning the masonry beforehand ensures optimal absorption and effectiveness. Overall, Stormdry has exceeded my expectations, providing a reliable and long-term solution to protect my home from penetrating damp.

Brilliant 🤩 Goes on like a cream then dries translucent and waterproof, I have tried throwing water at it after and it rolls off. Expensive but definitely worth it to protect bricks, while remaining breathable.

Again my parents wanted to colour and protect their wall in the garden, but because of their ages they wanted something that was easy to apply and durable.So I recommended this product due to the amount of paint you get and also the durability of it, My parents haven't got a huge garden but they did have a wall that ran half the length of the garden which this section was around 18-20 meters and the wall was breeze blocks. Now when they used the paint they did say that it wasn't too thick or too thin and because of this didn't cause a lot of mess.The paint did go on easy and dried in a good amount of time and even though the wall originally wasn't painted they only needed to do 1 coat and it did cover the whole wall without a problem once dried it didn't look patchy at all and did leave a good finish.So this is a great product to use and at a great price

Great product at a good price

Very impressed so far. Only time will tell long-term.Had a new gable end wall built for my loft conversion. Brand new expensive bricks to match the originals on my 80 year-old house. Then 6 months later we have the wettest winter for 200 years with winds from the south constantly soaking the wall. With no time for the bricks to dry out between the rainy days, they eventually absorbed the water all the way through and with no cavity wall for the water to drain into, the rain appeared on the inside of my house and dripped from the lintel above the window. The new bricks look nice but are clearly not a match for the 80 year-old originals when it comes to waterproofing. (How can brick companies sell bricks that are this absorbent?)Anyway, having done plenty of investigation on-line, I opted for Stormdry as the solution to the problem. I hoped the old maxim that you "get what you pay for" was true in this case as it is not the cheapest product around but we wanted an effective and long-lasting solution as I don't want to be having to put scaffolding up every few years to reapply a waterproofer.It went on very easily. We did it by brush to get into the nooks and crannies. You can certainly see where you have been and true to the instruction leaflet, the Stormdry was absorbed into the wall and the bricks returned to their original appearance after a day or so.About three weeks after applying, we hadn't had much rain so we soaked the wall by hose before the scaffolding came down, just to see how the wall would react. The water beaded and ran off the surface of the bricks. A couple of hours later the wall was dry to the touch which certainly would not have been the case before. It looks very impressive and l am hopeful that this will solve the problem long-term. Hosing the wall for half an hour is not exactly the same as the constant drenching the wall got during December 2013 but it gave us an idea of the effectiveness.Based on the quoted figures for coverage of the product, I bought too much rather than too little. Our bricks were so absorbent that they took twice as much as the stated amount (and I am convinced they would have taken even more if we had had more to apply). So I am hoping that the depth of effective waterproofing in my bricks is therefore also twice as much as it would have been.I recommend this product.

We had water coming into a downstairs room via the ventilation vents in the very wet and windy conditions we had over the winter. We initially thought it was the double glazing failing, but our normal firm said they were fine, despite the windows being over 25 years old. They suggested that it could be that our brickwork was porous and the rain so excessive (we face Southwest) that the normal weep vents in the brick couldn't cope and became overwhelmed. After some research I went for Stormdry Masonry Protection Cream, despite the cost, as it had good reviews. I found it easy to apply to the affected wall, in one morning (I am 67 but OK up ladders) and it dried invisibly. We have since had more heavy rain and SW winds but no more water ingress, so I am cautiously optimistic that it has worked. The inside wall has dried out and Stormdry's claim that it lets the brickwork breathe seems to be valid. After rain you can see the rainwater beading up on the brickwork and overall I am very pleased with it. Coverage is good too and I still have some left, just in case! I can easily recommend Stormdry Masonry Protection Cream, if you think you may have porous brickwork.

Awesome gear. Coated the external walls of our extension in this due to the fact that 'Wild Bill Crappy Builder' - who constructed the extension failed to install and adequate drip line into the coping stones on the roof. This stuff works a treat and the water just beads off the brickwork.
