Sealing limestone question

[ecarter94]

Hi all,

We had an outdoor limestone patio laid at the start of June (finished circa 07/06/24). We are yet to grout it. I'd like to seal it before doing so and I have bought Lithofin Stain stop. I have read a lot regarding its application however I have received conflicting information about when it is best to do so. I have been told that waiting to seal it doesn't matter/ we need to wait 13 weeks/ we need to wait a year to let it effloresce etc.

What is the general consensus regarding this?

Additionally, how long does it need to be completely dry before sealing it? Again I have read that 3 days is necessary but that's impossible at the moment with all of this rain!!

Thanks in advance

Where did you get all that info?
Where did you get the limestone from and what are their recommendations?
Usually, the seller tells you the steps to follow.
Since it is a natural stone, it is good to apply sealer on it prior to grouting. You follow the manufacturer's instructions, usually you must wait 24h to 72h then you can reapply sealer everywhere

Lithofin will have their own instructions on the tin to help you, for outside I tend to use water based sealers, like LTP H20 mattstone because it can be applied when tiles are damp, it's very helpful if the job is time sensitive within reason.
