Can You Seal Marble With Polyurethane

I m sorry there isn t a cheap easy fix for your problem but i not only answered your question i told you what it would take to fix it.

Can you seal marble with polyurethane. Oil based polyurethane for countertops. When a drop of water soaks into the marble and doesn t bead up it s time to seal. The installer says i can t apply a sealer because it wont penetrate in the stone because of the polyurethane clear coat that has on it but the previous estimater that came to me house says that they will goin to seal the marble i call floor and decor where i bought the. Use a sealer made to seal marble.

So in my opinion i would not use polyurethane on your marble top. Although it is possible that your table has a polyurethane or varnish finish it s much more likely that the marble was polished to a high gloss that has become scratched and dull. If residual sealer is not completely removed from the surface of stone it may cause problems including a haze on the stone s surface that may develop. Ok this is my question i bought marble tiles that has this polyurethane clear coat over that makes it look really shiny.

I also told you the only viable fix for your problem. Polyurethane varnish is one of the best finishes for a countertop it s durable and when applied properly can be just as subtle as lacquer. Also keep in mind that the sealer is intended to fill the pores and coat the exposed minerals in the stone not to coat the surface. If not you take the chance of sealing in dirt and debris.

The shine most likely will not last and and when it begins to break down it will look very bad.
