StoneTech BPSS4-1G BulletProof Stone Sealer, 1-Gallon Container

I bought this product and use it on my blue stone and full range flag stone a month ago, the result turn out very good. It is a little bit expensive, but it is well worth it. It was not too difficult to apply, I used two coats on my stone, on the first coat, the stone absorbed well deep into the stone, then the second coat 30 minutes after that would take less sealer than the first coat. It was paid-off after the first rain that we have, the water ran off from the walkway (depend on your slope) and standing water on the surface could not penetrated into the stone. It was like water standing on the glass surface. My wife have tested this product along with many other competitor on our spare stone, and this is the best that we selected. After apply different sealer on the same kind of stone, she tried to stain them with many different kind of stains, including oil. Many sealers do what it suppose to do, but "BulletProof" stand-out from its peers. The best feature of this product that we really like, is it did not change the look of the stone, and it did not make the stone shiny. Again, like any sealer manufacture recommend, always test them on your left-over stone before apply them to your walkway and follow the instruction.

Great product but came frozen. Apparently it happens in winter, be careful ordering in negative temperatures. I used it anyway to seal marble mosaics. It worked.

Very happy with the redults.

excelente

Top quality for a sealer at a normal price
