Tile Over Cultured Marble

Cultured marble and other cultured stone panels can have some shade variation and veining which makes them more decorative than acrylic or fiberglass.

Tile over cultured marble.

Tiling over cultured marble in shower. I sanded the cultured marble ledge applied tec double heavy duty ceramic tile adhesive sometimes referred to as mastic and applied a few test tiles. Cultured marble is an acrylic composite and so it will require an epoxy setting material after the surface has been roughed up with either a grinder or sandpaper. Live with it replace it or hire a company to come in and professionally refinish it.

Cultured marble is made of an acrylic resin into which marble dust has been mixed. If the wallboard is loose or crumbly you ll have to replace it before tile can be installed. Sir i doubt that any body has ever done that in fact i would go as far to say any contractor that was asked to do that would decline now you may find some one to do it but as i say i do not know of a contractor who would think this is a good idea or this will work. The first option is pretty self explanatory do nothing and live with the countertop you ve already got.

Epoxy is expensive but there aren t any other settings materials that will give you a reliable bond over this plastic surface. There are flexible thin set mortars that are recommended for bonding tile over tile too. Covering the cultured marble walls is not a good idea. Best of luck shaughnn.

Use the belt sander to scratch the entire area of the cultured marble where you will be installing the tile. After 72 hours however i decided to remove the test tiles to see if the rest of the mastic had also cured. Not the most glamours option but it s certainly the cheapest. In fact when it comes to making over cultured marble you really have only three options.

The mastic around the edges of the test tiles hardened and cured fine. Colors and sizes are more limited than with tile but the result is a clean and uniform surface. You should use a polymer modified thin set mortar adhesive that meets ansi a118 4 or better yet ansi a118 15 to bond the porcelain tile to the prepared marble surface. Use the vacuum to completely clean all of the dust and particles from the cultured marble surface where you will.
