Care & Cleaning for Cultured Marble

MPL Company is very proud of its craftsmanship and especially proud that our fine products are “Made in the U.S.A.” We guarantee that all craftsmen involved in the manufacture of our products have done their very best to ensure your satisfaction.


Normal Cleaning

Surfaces are semi-porous which means they are sealed so they can be easily wiped clean. Any Non-Ammonia-based and Non-Abrasive Based cleaner such as Scrubbing Bubbles or Clorox Spray will work well for routine cleaning. If you have stubborn stains or cigarette burns, you may want to use Acetone or Magic Eraser. To keep your finish looking like new, occasionally rub your matte finished product with a Scotch-Brite pad alone.

Remove any tape residue (from labeling) by using Acetone or Goof Off.



Minor surface scratches can be buffed out using polishing compound and Scotch-Brite Pad. Deep scratches or burns require light sanding, using a wet 400 grit sandpaper. Sand lightly with a circular motion in as small an area as possible. Wet the area amply while sanding. Remove the minor scratches which result from sanding by buffing with polishing compound. Clean thoroughly with soap and water when finished.

If the surface does become damaged repair kits are available. Please call Mike Mong @ 800-466-7465 ext. 233


Stain Removal

Many stains can be avoided by paying attention to the instructions for proper care of your MPL marble products. Please use the following steps to solve unusual cleaning problems.

Grease stains and oil residues can be removed with Acetone, mineral spirits or butyl-cellosolve (available from paint outlets).

Please read completely before you begin. The material in the patch kit can be extremely hazardous if not used properly. Keep away from children! If the catalyst comes in contact with your skin wash with soap and water immediately. As with all hazardous material please dispose of properly. Refer to the material data safety sheets for additional information.



How to Patch Cultured Marble

Is Patching Necessary?

Before you begin, try to determine how deep the chip or scratch is. If it is not deep, patching may not be necessary. You may be able to simply follow the sanding and finishing procedure below.


Surface Preparation

Make sure that the area to repair is completely clean and dry. Use a strong cleaning agent to remove any soap film or scale build-up.
Use 400 grit sandpaper or pocket knife to rough up the areas to be patched. Blow away the dust. You can also use a solvent such as paint thinner or fingernail polish remover for a final cleaning. (CAUTION: do NOT leave solvent soaked rags laying on the surface for extended periods of time as surface coat softening may result).


Mixing and Applying the Patch

Determine the depth of the repair. If it is not through the gel coat but yet too deep to simply sand and feather out, then simply use white gel.
Draw off approximately 1 oz of the gel coat into a small cup with a popsicle stick. Add approximately 5 drops of catalyst to the gel and mix in completely. Apply gel to the prepared area and cover with a piece of masking tape. Be sure not to press too hard on the tape; you don’t want the patch to be under-filled.

Allow the patch to cure overnight. If you are in a hurry, you can use a hair blow dryer to speed up the curing time. Run the hair dryer for about 30 minutes, remove the tape and let the patch cool for an additional 30 minutes.


Sanding and Finishing

Make sure the patch is completely hard. If your sand paper starts to gum up then wait a little longer.
We recommend that you mask off the area around the patch before you begin sanding. On flat surfaces always use a wood sanding block under the sandpaper. Always keep the surface and paper wet while sanding.
Start with 400 grit sandpaper and use a circular motion to sand the patch down. When the patch is level with the surface, switch to 600 grit to remove some of the scratches.

If you are sanding out a deep scratch or pit, you should use your finger to feather it out in a circular motion.
Remove the masking tape from the surrounding area. After the final sanding with 600 grit sandpaper, rub the surface with the maroon Scotch-Brite pad provided.
