Thanks guys. I will probably do a small area outside just so I can check the results in a few weeks. Don’t want any efflorescence in the grout lines. The interior pool house I will probably use water-based impregnator. I have a 5 gallon pail that I’ve been trying to use for a while.

I’m of the opinion that if you impregnate the limestone it will be easier to maintain. Of course since it is subject to the environment you will have to make sure it is clean and totally dry before application.
Solvent based products are generally  through the to penetrate better which would help with both life and foreign contaminant resistance. However, because the limestone is probably fairly porous, a good quality water-based should work well too.
Just remember, in that environment, it will probably have to be deep cleaned and re-impregnated every 12-18 months for the best protection.

Im not a fan of sealing exterior stone. Ive seen too many problems, especially limestone. Your better to just give them a maintenance plan.

Hello partners,

I am looking for some advice on cleaning and sealing the textured limestone floor. Part of it is inside of a pool house and also around the pool. There is some staining going on that I will try removing first and then give it a good cleaning with my floor machine and extractor.
I keep hearing stories about whether or not to seal limestone that is outside. I was thinking of a solvent-based impregnator.
Any thoughts?
