Fred,
 
What about sealing slate in a screened porch that is exposed to snow and rain. Would you also recommend not sealing as an outdoor slate patio?
 
Thanks,
 
Roger Konarski

I am never a big fan of using sealers outside. first the stone must be dry and in a outside environment that can be difficult. Second, any moisture that is below the stone will need to escape and sealing it could reduce the evaporation rate and could result in the stone spalling. I have seen it many times. Now, I am not saying dont seal it  but it is very risky

Why would you not seal this outside slate?

I agree..but test first for color bleeding.   Do not seal the outside slate as well.

Looks like bluestone to me. We clean with alkaline and or an acid.
Mason guys use muriatic we don't like to.

I'm not an outdoor slate person, so I need help on this one. Please see attached picture. The picture is the outdoor slate but they also have the same stone in a screened in porch. What product should I use to clean with, using my floor machine? 2nd question what should I seal it with? 
 
Thanks,
RK
