depends if you want a matt or shiny finish really
lithofin MN stainstop is the bench mark for matt finishes,but i believe steve from london stone paving (in your neck of the woods) has a new British product that works just as good for less money
I use a mister but some use a brush

Hi Jon

Not all natural stone needs to be sealed and there is no need too rush into doing it.

1. What type of stone is your patio?

2. Is your garden damp?

3. What sort of usage will the garden be getting?

We've been testing the new product dry treat out and the results have been outstanding. We have tested it out on our beige sawn sandstone (this is a stone which needs to be sealed) and it is really effective at repelling dirt. So much to the point that stains can literally be wiped off with a sponge.

You must mean this stuff

How much is it?

[London Stone Paving]

Thats the stuff Bob. Nice Research there .

Its £39 + VAT per litre. Its £12 more that we sell lithofin for but it contains more than twice the chemical content. The result is that it does not need to be re-applied (got to be a good thing) and it repels dirt to the point where any stains can be wiped off with a sponge.

As soons as we tell our clients it does not need to be re-applied the conversation is over.

We just want to be able to give our clients the best solution and the most cost effective solution.

When you say re-applied do you mean that when it's first applied it only needs one coat.
Or do you mean intially it may need 1 or 2 coats but it won't need reapplying a year or two down the line?

[London Stone Paving]

It needs 2 coats when initially applied but never needs to be re-applied in the future.

I'm an approved installer for drytreat and concur completely. Just watch it carefully on Black Limestone though

Good to see you back on the radar. You back to work now?

What is the issue with the black limestone?

Cheers

Thanks, I'm on light duties so to speak. That closeboarded fence I did today was an ideal example ??? ???


My inaugural drytreat job was on 260m2 of black lime we laid. I was trained at the site by them. He used one of their cleansers, made a right mess all over the flags. Also we seemed to get lots of white blooming which is still there. He's since said to just use one coat on black lime due to its low porosity.

Do you deal with Gary T ?

[London Stone Paving]

Yeh, he was down at our place today.

Thanks for the advice on the black. I was all set to seal the black limestone at our display on Monday with 2 coats of dry treat. Think I will just stick with one coat.
