Cultured marble is a synthetic material made from marble dust and resins, coated with a glossy gel. It can be molded into shower surrounds, benches, and vanity tops, adding affordable elegance to a bathroom. If the cultured marble gets chipped or drilled holes need to be patched, the same gel coat can be used to fill the holes. Gel coat repair kits are available in most cultured marble colors, allowing you to fix the problem at home.

Step 1

Sand the edges of the chip or hole to smooth it out, ensuring there are no rough edges. The area should be clean, dry, and ready for patching.

Step 2

Prepare the gel coat patch by pouring a small amount into a bowl and adding the catalyst and pigments. Thoroughly mix the ingredients with a craft stick until they are well blended.

Step 3

Take some of the patch mixture with the craft stick and apply it to the chip or hole. Overfill the area slightly, as the patch will shrink as it dries. Use the stick to feather the patch onto the edges of the surrounding cultured marble. Smooth the top of the patch as much as possible with the edge of the stick. Allow the patch to dry overnight.

Step 4

Inspect the patch for any shrinking or cracks. If the patch has shrunk too much and exposed a crack, apply additional patch to fill it.

Step 5

Moisten the finished patch and sand the area with fine-grit sandpaper until the patch is smooth and blends in seamlessly with the surrounding area.

Step 6

Apply a clear coat of gel onto the patch and the surrounding area to restore the shine and ensure the patch blends in with the rest of the surface.
