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

Easy to apply, doesn’t smell awful. Seems to be working, not cheap but does come with a guarantee

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.

I needed to cover an outside wall that appeared to be letting damp in and then leaking into my garage the other side. The quality of this appears to good and there is noticeable less damp, so the leak prevention appears to be working. I wish it was cheaper, but it could be a lot worse. I recommend trying it if you have damp issues for outside walls.

WOW BRILLIANT PRODUCT 5STAR. WATER PROOF FOR ANY EXTERIOR SURFACE, BRICK WORK IN PARTICULAR, needs a day to properly, easy application and goes a long way.

I've read a few reviews on this item through google and u tube and decided to get some its very easy to use and its been on my house for almost a year now and its durable the coverage is good i also managed to spill some on my paving stones and when its wet i can see exactly where it was so yes it works

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.

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.

Expensive but exceptional - this was applied to Tyrone Rustic Brick on an exposed chimney stack on a bungalow. When applying, recommended a dry chimney stack, and allow at least 8 hours after for no rain, but preferably 24 hours is best. Despite the rain from Storm Amy Over two days, no rainwater penetrated the brickwork indoors. From the spec. It suggests that even greater weather protection occurs as the product soaks in and cures. At the time I thought expensive, but given the repair that it has saved me having to do it was well worth the £124. That said I am left with half a bucket of product. You are advised Not to apply twice as it ruins the breathability of the product. The longevity of 25 years yet to be tested but if it lasts for 10 I will be happy. It is so easy to brush on. Thick and creamy consistency, paints on white and in about 10 mins turns clear and runny. Within about an hour it’s barely visible. I would suggest wire brushing the chimney first as recommended to remove any debris or lichen. If you have any dampness this is the cure. Cannot recommend product highly enough.

Dekt goed

Product werd verwerkt met borstel Silverline 15 cm. Product laat geen vlekken na op de gevel . De regendruppels dringen niet meer in de baksteen. Product is vrij prijzig maar doet wat het belooft.

Tolles Material (wie Puddig 😄). Lässt sich super verarbeiten. Habe es in einen Rolleneimer umgefüllt, ist einfach ohne Rückstände im Origenaleimer in den Rolleneimer herübergeplumps. Wurde von der Fassadenfarbrollle gut aufgenommen und ließ sich super auf die Wand aufbringen. Jetzt warten wir auf den nächsten Starkregen, ob dann die Wand keine Feuchtigkeit mehr aufnimmt und das tröpfeln über dem Fenster aus dem Fenstersturz aufhört. 🍀 UPDATE: Die Creme hält was sei verspricht, es hat mehrfach teils stark geregnet und dass Wasser perlt einfach ab. Es dringt keine Feuchtigkeit mehr ein und das Tröpfeln aus dem Fensresturz hat auch aufgehört. Super Produkt, sehr zu empfehlen! UPDATE2: Jetzt ist der Ansrich 1 Jahr auf der Wand und alles ist weiterhin dicht, und auch Starkregen perlt weiterhin ab. 👍🏻

Ottimo prodotto impermeabilizzante Recensione: Prodotto molto valido, facile da applicare. Non cambia il colore della superficie e respinge perfettamente l’acqua.

Es genial, lo apliqué en la pared de la terraza, que está forrada de piedra. Es muy viscosa, pero se aplica bien. Una vez seca la piedra quedó del mismo color.
