How to Stain Cultured Marble

The finish is pristine and the material is durable, which makes cultured marble a popular choice when redecorating or designing countertops and flooring. If the color of the cultured marble countertop, bathtub, sink or floor has fallen out of favor, it is possible that it can be stained to change the style or bring the shade to a more modern hue. You can resurface a cultured marble vanity top or small kitchen expanse of countertop in a few easy steps and have an entirely new space in an afternoon.

Benefits of Cultured Marble

Cultured marble is known for its flawless finish that can withstand high traffic. It is also low maintenance and durable. It is easy to clean and comes in a wide variety of color and design options. Cultured marble is made from a porous blend of resin with natural pigments and mineral fibers. The mix is put into open molds and sprayed with a clear gel coat to make it durable. The gel coat creates a shiny and perfectly smooth surface that is stain resistant to a point. This procedure makes it possible to create patterns, mottled matte finishes or super high-gloss finishes. The cultured marble is relatively easy to install.

Cultured Marble Countertops

Cultured marble countertops are stain resistant, easy to install and inexpensive. However, they can get marred from everyday use over a long period of time. Before refinishing, the countertops should be cleaned and any chips, cracks or scratches need to be repaired. When cultured marble gets a mark, it is a fairly simple process to return the surface to its pristine sheen. Sink repair for a cultured marble fixture can require more work. If the surface of the cultured marble sink is cracked or has a deep gouge, sanding down the edges of the divot to blend in with the rest of the sink can solve the problem. A gel coat patch can hide the damaged area.

Shade Shifts for Cultured Marble

Bathroom vanities and kitchen countertops that are made of cultured marble can easily be changed. If the cultured marble is a wide plain of boring white, a swirl of stain or paint can be applied to add depth and texture to an otherwise bland surface. If the cultured marble is mottled with color or specked with black against a light background, a coat of stain may shift the shade from light to dark to create a more pleasing look. If the pattern on the cultured marble is entirely too busy to change with a stain, a layer of paint can create an expanse of even-toned color.

How to Stain Cultured Marble

After thoroughly cleaning the surface and allowing it to dry, gently sand the entire piece of cultured marble countertop to expose the material. This will remove the sealant and allow the new stain to be quickly and uniformly absorbed into the countertop. Tape off areas that can be damaged by the stain you plan to use or where you want a crisp line of stain, such as along the walls or mirrors. Stain can be brushed onto the cultured marble surface. However, a small paint-spray gun will give a more even shade to the surface. Practice on a piece of plywood or other absorbent material outside before tackling the main project. Apply the stain in thin, even coats. Once the stain has dried completely, apply a coat of clear sealant. Let that dry thoroughly before using the area.
