Pro-Kleen PatioSeal Matt Patio Sealer/Sealant (10 Litres) for Indian Sandstone, Concrete, Paths, Patios, Slate, Brick, Indoor/Outdoor Hard Floor - Lasts up to 10 Years (2 x 5 Litres)

I poured sufficient content of the sealer into a sprayer, pumped the sprayer to create pressure and pressed the button. Easy. It covered the slabs well, with some pooling (as I had noticed on other reviews) but this was not a problem as it all soaked in. I guess it would depend on the type of slabs that are to be sealed but guidance is provided as to which ones are suitable. Mine are of Indian Sandstone. Very pleased with the result. It remains to be seen as to how long the seal continues to protect the slabs............

This product needs to promote itself more as finally after 2 years searching through matt and gloss "clear" treatments this one actually leaves no trace. The natural stone patio with slabs of various types, shapes and sizes had to be treated carefully and individually with a FINE spray to ensure each is saturated (looks wet) but NOT flooded. Some types take more than one pass with the sprayer which MUST be kept moving constantly. Mop up any drips/splashes when the pressure of the sprayer runs out. Don't empty the sprayer completely as this also leads to splashes and an uneven coverage. Practice with water first to get the technique right if you're not sure but wait until completely dry before application.

I sprayed this on monobloc after it had been pressure washed to clean it. This is the first time I have used a patio sealant on it and I found it very easy to use. I thought 10 litres would have been enough to do the area I have, but had to order more to finish the job. Two months later my paths are just as clean and they seem to dry quicker after any rain than they did before. I'm impressed with this sealant so far.

Good quality product that is easy to use. Succesfully applied to front drive (concrete crazy paving) and two rear patios (sandstone). Delivered when they said it would be.
