polyurethane


So- The latex on the ceramic might already have an adhesion problem unless it was primed right, and you want to put a clear ? poly over it?
Why?

I would not do it. If you really have to put a clear coat on, use a water-based polyurethane.

I agree, Gym. Oil-based polyurethanes have ab amber cast and continue to yellow, discoloring what you are trying to protect. Zar or Varathane (And others) offer water-based polyurethanes that will perform better for this purpose.

polyurethane


Where is this ceramic tile and have you put down the latex paint yet?

If these are pukey pink 50's shower tiles, don't even go there. It wont last. It will peel and look worse that what you have.

Really good point, Blondsense. Nothing looks worse than painted tiles, especially when they start to peel, chip, etc.

So we can better assess the situation, please tell us if the ceramic tile is already painted or if you plan on painting it.
