I did quite an extensive search when I went looking for a brick sealer. I,m pleased I decided on Smartseal. Very fast delivery with no hassle. After reading the directions I decided on the use of a spray gun. By far the best way to apply this product. Very fast and direct making it easy to get into all the brick blemishes. I has to wait a few days before it rained and I was able to see the performance. I couldnt fault it at all. It did exactly what it said it would do. Highly recommend this product

By Steve Knight

The brick sealer is really easy product to use. Used a spray gun and it was effortless no odour or staining

By Patricia Bateman

Great product from a great company. The brick sealer did exactly what it was meant to do quickly and efficiently. Delivery was also first class.


Purchased this product but not used as yet. However, having used various Smartseal products recently I know and expect that this will be no different to others in producing excellent results. If you want a product that WORKS, dont waste your time and money on cheaper alternatives!

By Brian Maw From Sheffield

Awesome love it 25 L interior brick looks beautiful cant wait to use more

By The Scary Guy

The brick sealer is easy to use, coverage good and has done the job, as after it has rained water lays on top until it dries.


Well eventually got round to applying the Brick Sealer yesterday. Good communication and delivery from the supplier, the product was easy to apply and good value for money at the reduced sales price. Only time will tell how it performs against the weather, however in saying that their masonry cream proved to be an excellent product hence my purchase of the brick sealer for my garage wall.

By Jim Kennard

Hello, Does this Brick Sealer stops moss if I apply on my walls on Driveway both sides and how long this Bric Sealer lasts?

By Bachu Patel From NORTHOLT

Large puddles now sitting ON TOP of my wall after recent downpour says it all. Slap it on !! this brick sealer really works PT

By Peter Thomson

Very satisfied with quality of the brick sealer. Easy application. Very good final results.

By Anna Oram

So far so good. Easy to put on, water comes off treated bricks like off a ducks back. Hopefully remains effective in the longer term.

By Penny Ralph From Yorkshire

Esay to apply by brush. Water beads on the top surface of a brick wall a couple of weeks after application. Supposed to be good for at least 9 years. Time will tell.

By Alex Donald

Sample received quickly and easy to apply. Will have to wait until the next heavy rainstorm to see if it helps.

By Angela Shaw

The brickwork on our house is very porous and every so often we get flood water around us up to 30 cm high so every few years we go round and waterproof up to 50 cm high . This is the second time we have used the Smartseal product. The sealer is easy to apply and protects the walls adequately for several years.

By Joan Danvers

easy to apply with a sprayer, does not discolour the brickwork, I hope it does it's job

By Christopher Fallon

Applied the brick sealer with a brush. Easy. Delivery 5* Seems good product, but in this case will not know until mid winter. It is then that I can opine on the effectiveness. contact me then.

By John Baker

By Kevin Lewis

This is an excellent product It was so easy to apply with a sprayer The following day I tested by throwing water on it and it literally repelled it > Would definitely recommend

By Sue Pigott

Thank you Smartseal, for a great prompt service. Mandy was exceptional in both her professional knowledge, efficiency and very good humour. I felt I was dealing with a family company who took time and patience with silver surfers like me. Alex Giannotti was also a nice person processing my order as requested. AD Allis

By Tony Allis From Kenilworth

great delivery, easy to apply, solved my problem

By James O'Keeffe

The product arrived very quickly and was well packed. It was very easy to apply ( so easy that I thought I couldn't have done it properly). It dried and sealed the reclaimed bricks on my new fireplace and so far it has kept the dust down effectively. It also did a brilliant job of slightly enhancing the colour of the bricks. I only used about one fifth of it so have plenty left for a recoat should it need it in a year or so. Smashing product.


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.

By Joan Danvers From North Yorkshire

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 !!!!

By Pete T. From St Albans

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.
