Hi, I need to seal polished sandstone paving slabs and was wondering what the cheapest but effective option ?
Would Thompsons Waterseal do the job ?
Many Thanks

"Cheap" and "effective" tend to be mutually exclusive adjectives when it comes to sealants.
You spend a lot of money on polished sandstone and then want to daub it with summat "cheap"? Why would you do that?

Was just askin the question if it would be suitable ???
I noticedv they now do a Thompsons Sandstone sealer, at £20 for 6m2...bearing in mind the area is 50m2, I'm not sure if spendin £300 just for the sealer is exactly "cheap"
Does that sound reasonable ?

if you have cheap sandstone that you will have to change if and when the cheap offers go wrong then thats fine but we do know whats good and whats not and the german gear is the bees knees search about you will get it cheaper buy in 5litre can :;): ???

I have a very low opinion of Thompson's stuff. Their Patio Ruiner makes me extremely distrustful of their sealants in general and what I've seen of the sandstone jollop makes me wonder what's the difference.
The point I was trying to make is that when you've spent a lot of money on a processed flagstone, it doesn't make much sense to risk devastation by daubing it with a cheap sealant. There are proven sealants available, and while they aren't cheap, as long as they are correctly applied, they will augment your paving as well as protecting it.
If you were talking about plain grey 2x2s, I wouldn't worry too much, but what you have is a bit too valuable to risk with anything even slightly iffy.

i would have thought that 4 litres of lithofin MN stainstop would do your 50M2
roughly £100 and a couple of hours to apply on a nice dry day
