Smartseal Premium Concrete Sealer - Internal & External Use - Breathable & Impregnating. Highly Protective Concrete Floor Sealer and Concrete Sealer for Walls (2 x 5 Litre)

You need several applications for this job even with hair line cracks not visible to naked eye

The sealant was easy to apply and the sample was sufficient for my needs. It was effective in sealing the area, but the problem was deeper and needs more than a quick fix

I did not really need a full bottle so bought this tester and it was brilliant. I only needed to cover a 1.5 m square and it was more than enough for that.

Had to cement over an air brick, I used this solution to seal the cement, I give it a good soaking. Went to put a 2nd coat on the following day and it just rolled off, so the first coat had done its job.

Wanted this to seal a concrete step outside my back door which was very dusty and tracking dust into the house. Guess what? After two coats nothing has changed. Thankfully I only bought the sample bottle but £4.95 for 100 of water is rather pricey. Someone is laughing all the way to the bank……..

Just watered down PVA, save your money!

Did the job, recommend, not much else you can say about this product

Bought to seal a concrete bird bath it worked great
