StormdryMasonry Waterproofing Cream (1 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.

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

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.

Well impressed

Stormdry is a revelation albeit expensive. Royal Mail delivery should be avoided- a 12 hour timeslot for delivery is totally unacceptable for Amazon Prime and necessitated me keeping and paying for workmen as expecting delivery from 07.00am as advised by Royal Mail.Further update - my house is 323 years old and has solid brick walls. Although well made and solid bricks, over time they have become porous with small damp patches showing indoors after recent strong storms with driving rain. Since treating with Stormdry and repairing the pointing with Stormdry Mortar, the damp patches have disappeared and the rain visibly runs off them. What is particularly pleasing is that the house, since application, is noticeably warmer. I looked this up on their website and YouTube and it would appear that damp walls conduct heat more than dry ones. I am extremely pleased with this product and highly recommend it.

Arrived on time. Does what it says.

Bought a 5 litre tub to paint my small extension. Disappointed with the fill level. I just bought a smaller tub and that was filled to the top. Anyway, one wall on my extension is north facing and gets battered by wind and rain in a storm. I painted the walls with this using a masonry brush but it didn’t look as white when I was doing it like other pictures however time will tell on how waterproof it is. Had to buy another tub for the front of my house as it doesn’t go very far.
