Hi all - found this forum while trying to find a solution to my problem, and it looks like I hopefully found the right place - hoping you'll be able to help!
We're currently renovating a bathroom, and putting in a slate tile floor. Now, what we'd like to do is run a small (~6" wide), winding 'river' of river rock/pebbles down the middle of the floor. That part isn't a problem.
The issue is, we'd like to cover/coat it with some kind of clear polyurethane or something to a) seal it, and b) bring it up to the level of the surrounding tile. Basically, my wife wants the look, without having to worry about cleaning up dirt, etc stuck between the rocks, or someone tripping on the uneven part of the floor
(and yes, we realize that the slate itself won't be perfectly level, but it's pretty close).
Now, we've seen this done in a showhome once a few years ago, and it looked really nice - but I have no idea what product they used over the rock. Can I just pick up some generic clear polyurethane or something from my local home store to seal/cover it with, or should I go with something else? My concerns are basically:
1) Needs to be waterproof (it is a bathroom floor)
2) Worried about it yellowing/discolouring with age
3) Durability/resistance to scratching, etc.
Any suggestions would be appreciated! I've tried searching, and found lots of posts about people using river rock in showers, etc, but nothing quite like what we're doing.
