This is a excellent topic look forward to seeing what you find out 👍

Love the vids by the way mate 👌

I’ve just finished laying the exact same slabs, they look great with the buff sweep in compound(silka) my customer insisted it wasn’t sealed as the wanted the most natural look possible, hope your well John 👍

That needs to be your Moto "Belt & Brace" 😂🤣👍🏾

Research that's what it's all about,that's why people watch your channel Jonny boy, because you are good at what you do,stay safe my friend 😎😷

Hi Johnny, hope your coping well in the current situation!

Really appreciate you giving some clarity on sealing. I had a dark grey sawn, honed sandstone patio and steps laid and then sealed with the sealant recommended by the contractor’s stone merchant (a water-based, impregnating sealant). Within a month the sealant had failed, with some areas peeling off and other areas with milky blotches as well staining pulled through from the pointing. The contractor used a hot pressure washer and a lot of it came off, and then I tried a chemical cleaner recommended by a stone specialist. That was 2 years ago and the paving, which was Around £70-80 a square metre, still looks terrible and I haven’t been able to re-seal it so it’s not protected from other stains or pot marks etc. To be honest, I think it’s wrecked for good. But I have a fair bit of the sandstone left over (which I am going to try and superficially re-hone as it’s a bit battered from being shifted around the garden) and am planning to lay it in another area but have been struggling to get the right information about how to pre-seal and with what and you get different advice from every person you talk to. So it’s been great to find your channel, thanks very much!

I would make the client aware of the pros and cons to seal or not to seal. Thats their choice John, if they want something to stay looking new, they have the option to use those alternative products that are available 🤷🏻‍♂️ Personally if I have to lay sandstone, I would always like to seal it once laid to a matt satin finish

Thanks for the info. I'm about to DIY a sandstone patio and trying to decide if/when/what with to seal. Any suggestions welcome!

Blooming John boy , had it in paving many times after sealing , be careful, we have stopped doing it now , wonder if pre seal would stop this ?

Try storm dry masonry paint it's not cheap but water beads off

Hi Johnny, ive just subscribed, you are a wealth of knowledge and a bit of a Guru to all with your sound advice. ive watched lots of your vids and i am about to attempt a 60+mtr square sandstone patio, Thinking on Kandle grey or the Raj, wanting smooth not riven, 600x 900. So, my first question of maybe many :) did you ever sort out the best sealer and is it wise to seal before you lay? (i have searched for appropriate vid amongst your many uploads) Thanks in advance for any updates, keep safe and keep up the tutorials, best regards LI.

hi Johny ! What did the expert you were meeting has said about what and when to use the sealing ? Did you make any video regarding this after meeting the expert ?

Hi bud, just about to lay a limestone patio at my house, laid a lot of sandstone in the past on various jobs but never limestone, just wondered if there was any difference in sealing it after and also as it’s now winter is it best to leave it a while before sealing? Or when is usually best? Thanks

Hi Johnny I’m laying Kota black limestone soon for myself, I’m looking at azpects slate and limestone sealer, is sealing a must with limestone before grouting? I was going to just seal the top after laying, What’s your thoughts? Thanks. keep up the good work!

Hi Johnny currently laying kandla grey sawn/honed Indian sandstone my question is if we seal it will we loose the natural look you get when it gets wet? As I like how you get two different looks when wet and dry. Thanks atb Andy

I’ve always been told to wait for the salts to expel before sealing otherwise you seal the salts in as well. This is often months down the line.

Any update on the sealants johnny, we have not yet used any and we just had to replace a patio for a customer who put a sealant down on there paving as the water would just sit on it and was very slippery. But i do think a sealer that works would be good as customers do always ask us about them and upto now we avoid them as nervous if we have any issues with it. Appreciate your input. Thanks Sean

so which sealer would you use on sawn/honed kandla grey?

I had a patio just made with grey sandstone. It was not sealed and not told anything about that...I just found out myself after seeing the patio looking really dirty in a short time. A sandstone patio that has already been stained, mainly by bird droppings, can be recovered and sealed? Or is it too late? The patio was laid about 4 weeks ago

Whats the best product for a path block paving sandstone etc

Can you recommend a product to clean green mould from grey indian sandstone, thanks

How much is the paving per square meter?

How long after laying a patio can you seal it??? I was told 6 weeks after laying is a minimum???

Always insist on sealing especially if trees and bird droppings are inevitable , bird shit acid bites into the stone and is very difficult to remove. And it promotes maintenance, so often we do lovely jobs for people that don’t look after it and a sealer at least prolongs the lack of maintenance !!
