## Overview

Stormdry Masonry Waterproofing Cream is a premium, colourless exterior sealant that penetrates deeply into brick, stone, mortar, and concrete to form a breathable, invisible water repellent barrier.

Easy to apply and scientifically validated, it preserves the natural appearance of masonry and ensures long-lasting durability.

## Description

Product Description Stormdry Masonry Protection Cream Stormdry Masonry Protection Cream is a transparent waterproof brick sealant compatible with masonry, brickwork, mortar and concrete. When used on the exterior walls of the home, Stormdry Cream water sealer delivers energy-saving benefits by waterproofing and sealing substrates to reduce heat loss. It penetrates up to 12 mm on Fletton brick, preventing penetrating damp to protect the internal fabric of houses. The invisible waterproof silicone cream can be applied by brush, roller or airless spray. Stormdry Cream cures to a natural finish. Approved by the British Board of Agrément to last 25 years after one single coat. In independent tests carried out by a leading energy saving assessor (Alan Pither Ltd), a solid wall semi-detached house with Stormdry Cream application was found to save 8-10% on central heating costs when compared to an unprotected house. When independently tested by world-leading processes testing laboratory Lucideon, Stormdry Cream was found to enhance the thermal performance of brick walls to create a kind of waterproof insulation. Lucideon proved that Stormdry brick sealer shields brick walls from frost and heat damage. Stormdry Cream also protects against light spalling and cracks when compared to unprotected brick walls and can work as a concrete sealer. Stormdry Cream lines the inner pores of brickwork instead of blocking them, maintaining their natural vapour permeability. Following their tests, Lucideon confirmed that Stormdry Cream transmits water vapour while protecting against liquid water. Stormdry Cream is suitable for application to buildings with cavity wall and internal wall insulation as a clear exterior masonry paint. In both cases, Stormdry Cream protects insulation from dampness to enhance its thermal performance. In homes already afflicted with penetrating damp, Stormdry Cream stops further moisture ingress as a wall sealer. This allows damp buildings to dry out and prevents penetrating damp in future.

Review: Easy to apply. - 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.
Review: Brilliant 🤩 - 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.

## Questions & Answers

**Q: How much does 5 litre cover?**
A: I have covered about 18sq metres and have about a litre left.Coverage can be affected by surface preparation and porosity of bricks - you must give brick work a really vigorous brushing before application.

**Q: I have moss growth on my roof tiles. Will Stormdry prevent or reduce moss growth if applied to roof tiles after moss is removed?**
A: Yes I used it on my rebuilt chimney stack and roof tiles I have a spare roof tile in my garden that I treated with Stormdry in July 2015 when I spray it with the garden hose the water just runs off it it never gets wet be sure to follow the instructions when application I have been in and out of the building trade for the past 30 years in my opinion this is the best product on the market for protection of masonry its expensive but worth every penny  be careful when removing the moss from you're roof tiles if you use a high pressure hose always spray on the downwards slope  the way rain runs off if you spray upwards with high pressure water will go inside the roof space hope this helps Bryan Bailey

**Q: Does it work on K-rend**
A: Yes, it does

**Q: Can this be applied to MDF wood bath panels?**
A: This product is for hard materials like concrete, brick etc. However there is another product very similar for wood which I have used on a shed and a fence. It's called Roxil and has exactly the same appearance as Stormdry. When you brush it on it reacts to the brushing action in exactly the same way too. Once applied water will not penetrate the wood and just beads on the surface. Definitely recommend it.

### ⭐⭐⭐⭐ Very good product and also very durable
*by J***N on 28 November 2022*

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
