I now have another dilemma. I went to the tile store this weekend to get the sealer, and they asked me if I wanted a water based or solvent based sealer. I have no clue what it is and neither does the previous owner, as he had it professionally done. But he did leave behind a small tupperware container full of maybe a quart of what ever sealer the professionals used.
Any way of determining whether I have a water based or solvent based sealer? Water still beads on the surface but I'd like to do it again.
What does the sealer in the container look like? Is it clear like water or does it look like milk? Does it have an odor, if so how strong, what type of odor?
Use a little in an unconspicuous location and observe what happens. Does it coat thoroughly when spread? Does it soak in right away? Does it shed and bead and fish-eye?
It looks like olive oil, it's not milky or opaque at all. I'll try to get over there to take a "wiff" of the stuff tomorrow and put a small sample in the laundry room next to the washer and dryer, to see what that does. Then I will get back to you.
