Applied to the bottom 1/2 metre of our bungalow as every few years a stream that runs through the garden overflows and we are surrounded by about 10 cm of water. The bricks are very absorbent and we were getting some mould growth in wardrobes. Since applying the sealer we no longer have a problem. Great product.

No more leaks in flat-roofed utility room after applying Smartseal to brickwork above it.

By David Moseley

Used on an internal kitchen wall. After 2 coats was unable to apply any further coats due to absorption and waterproofness. Looks great and repels water instantly.

By Stuart From Hertfordshire

Excellent odourless product. Applied to brick slips on kitchen wall, has made them resistant to water and food splashes and stopped the dust falling too, just the job!

By Lyn P From Dover

I have just this weekend treated some brick walls with your brick sealer. Having "Tested" it with a blast from the hose, I can see already what a brilliant job it has done. However, good though it obviously is, it will not last forever and so I just wondered how long you think it may last before another treatment was required. I realise that you cannot be specific but have you got a recommended period of time before re-treatment?

By Pete Thompson From St Albans

The product arrived promptly and I have treated 2 or 3 walls just this weekend. The Brick Sealer was odourless and pleasant to apply. It even seems to have enhanced the colour of the brickwork. After 24 hours, I gave 1 wall a quick splash with a hose for a "test". The water just formed globules and bounced off. Brilliant product, perhaps a little expensive, but well worth the price. Thank you Smartseal !!!!

First class service & delivery.

By Creag Fenwick From Gloucestershire

I have absolutely no idea how this product work...it's the consistency of water and is virtually odourless, but I slapped it on my brickwork in a cellar I'm converting and it's done the job" Highly recommended, thanks to the salespeople I spoke to as well, very helpful.
