Indian Sandstone Sealant

Anonymous user 13/08/2025 - 2.31 PM

Hi, I've just sealed my newly laid Indian Sandstone patio yesterday evening and I've noticed today that any water on it isn't drying up. The patio itself doesn't get any sun on it, but I thought with the heat itself today it would be dry by now. It's just sitting in puddles?

Are you a tradesperson and able to answer this question?

It’s because they have been laid level and not with a slight fall on so all it will do it collect in puddles.

Hi there, yes with Indian stone been a natural product the surface of each individual piece is often uneven therefore small amounts of water may collect in small quantities of certain pavers. Or simply the patio when layed has not been given quite enough fall.

Hi, this is a common problem after sealing slabs, your answer is diluted washing up liquid!! This will reduce water tension on the slabs and allow water to flow.

Maybe due to using an excess of sealant and so is not drying out. Mop up the excess and it should dry. Sealant is not like water and does not necessarily dry in the same fashion.

Hi there, This is completely normal after sealing - don't worry! The sealer is working correctly. Fresh sealer creates a water-repellent barrier while curing - Without direct sun, evaporation is much slower - Water pooling shows the sealer is protecting the stone - Full cure takes 24-48 hours - Water should start beading and running off once fully cured - Give it another 24 hours and you should see improvement Quick tip: You can gently squeegee standing water if needed, but avoid heavy foot traffic until fully cured. If still pooling after 48 hours, the sealer may have been applied too thick or in unsuitable conditions. The water sitting on top (rather than soaking in) actually shows your sealer is doing its job protecting your patio! **TOBRANS Construction**

Hi there indian sand stone paving not a great fan. They often are not the same thickness and taper in the corners when laid they will be uneven and dip. This causes pooling. Hopefully there laid with a fall if you seal sandstone and you have used epoxy grout which allows water through the joint you may have sealed the joints.Hope this helps.

Well can you relay the stones with a slope ? A run off , and maybe a small pond to collect the water will help fix it. To get the sandstone porous again, abrasion with a stiff bristled brush would make a difference after time - but so would sun shine as it would degrade the chemicals - its a shame you don't get any sunshine on it. If you turn the stones the other way up they might be absorb water still. Hop ethat helps.

It's been layed with no run off so the water has no where to go

I would of recommended to seal the patio after a few months to allow the material to settle and the pooling I assume would be due to an inadequate fall of the surface I hope this helps

If the slabs are sealed it stops water penetrating So it will sit on top of the slabs 1 in 6 fall is needed to disperse the water Slabs are a porous product
