Product Reviews
By Mark StratfordFROM Devizs

I have a new build house with a single skin garage it was fine in the summer, but the walls were quite damp in the winter resulting in a somewhat wet garage. I spent some time looking at various products before I went with Smartseal, but I'm really pleased with the results of the brick and masonry sealer. Despite driving rain my garage is dry, the product was really easy to spray on and it only took a few hours. I would definitely recommend Smartseal it has saved the contents of my poorly built garage!

This brick sealer is very easy to use I used a spray gun with small overspray to reduce product going onto windows. Needed the 2 coats as soaked into bricks very quickly. Finish is great the original brick colour showed through. Will use again and recommend.

Product FAQs

Q: Hi there My question, can you use this product to seal a brick wall that has been rendered and painted?


A: The brick sealer can be used, but the paint and render will inhibit the penetration of the sealer. At best, the benefits would be greatly reduced. You can always try a sample 1st and gauge the results.

Response from Nigel

Q: I have a property with lime mortar, where a panel of bricks are exposed and displayed internally.. I want to seal the bricks to preserve the appearance whilst still letting the wall breathe.. what is the best product

Mark Chapman

A: You can use either or Brick Sealer or Masonry Cream products. They are both breathable/invisible sealers that will not change the appearance. The Masonry Cream is the superior product that can last up till 25 years. The Brick Sealer can still last up to 10-15 years. We have samples available for both products.

Response from Christie

Q: Will applying this on the outside brick help with mould, humidity and (lack of) thermal efficiency on the inside of the room? I have a room with three outside walls and it has high humidity and prone to mould..


A: Yes, as the brick sealer would act as a barrier, it would prevent damp ingress not allowing the mould to thrive in moisture. This in term will help with the thermal efficiency within the property.
