Black limestone indoors

Ye it was just mentioned that it would help ingress as well but having not tried it , then I can't comment on that side of it 100%.

let us know your thoughts if you test it out.

my advice.... allow all stone tiles to be in the property 2-3 days minimum before installation, to check viable shade / compatibility, wash stone before sealing liberally, taking the joint gaps into consideration, until the pourosity is greatly reduced after installation, just be careful when you install the stone, with sponge and bucket.. allow grout to fully cure before washing, and drying before sealing again, do it all with care and pride.
