Hi Partners,
I am going to be cleaning and sealing a half covered outside porch made with light colored travertine tiles.  I have a ton of SCC color enhancing sealer and because this is an outside project (not worried about the odor) I would love to use some of my stash up.  I am worried about the stone sucking up the sealer in an irregular way and looking blotchy later.  I am concerned about the sunny side of the porch fading more than the shady side.  I can test a small are to see how much darker it will make the stone. 
Also, would anyone recommend the SCC water-based sealer.  I have a few gallons of that too!
Thanks,
Barry
