Miracle Sealants 511 Seal & Enhance 946ml (US OT) One-Step Sealer & Enhancer

Brilliant! Does actually what is needed. The dull grey slate looks stunning and all the colours and textures can be seen in all their glory. Very easy to apply, but I didn't need the large bottle. I have barely used anything on 12sqm. Highly recommended!

Nearly had a fit when I saw size of the bottle. Thought it would never cover the patio I had bought it for. Not quite finished yet but I think I will jphave enough for another coat. We had a patio put in last year and within weeks the slate had gone to look pale and dirty. Now, it looks superb. Expensive, yes, but well worth it for the look alone. I will see what it looks like in a years time and comment back. But for now, it's done exactly what it says it does.

It works well on our newly laid porcelain tiles outside our summer house. Very happy with the result.

Expensive but worth every penny,treated 35 m2 of limestone flags using about a third of the contents.

It works perfectly

Thanks.
