How to seal marble countertops
Q. I have been told by my contractor (retirement home) that I can use marble tile for the counter tops in my kitchen. And, that it is up to me to 'seal' the tile & grout. Can you give me any information as to what to do & what to use??? I've done several web searches & have come up with conflicting information. Any type of info would be GREATLY appreciated. Thanks, JLBudd
A. First, I would recommend that you not use marble. Granite would be a much better choice for kitchen counters. Marble will become etched when acidic liquids get on it. Sealing the marble will help inhibit stains from being absorbed into the stone but it will do nothing to prevent etching. Granite, on the other hand is not generally acid sensitive.
You will want to have the stone and grout sealed. Use a high quality water-based sealer.
After everything is installed, let it cure for a couple of days, then seal the grout and the tile. Be sure to follow the instructions on the label.
