The Way to Refinish Cultured Marble Vanities

Cultured marble countertops are easy to clean and offer the appearance of more expensive stone. If you use abrasive cleaners, however, it is possible to scratch the shiny gel coat surface of the cultured marble countertop. As long as the scratch isn’t too deep, you can refinish the countertop with the assistance of automotive finishing compound and a buffer. When the gel coat is eliminated, the countertop will be dull no matter what you’re doing. Though it seems counterintuitive, you have to first roughen the surface with sandpaper before it is possible to restore the shine.


Turn off the water supply valves into the sink. Run water out of the two taps to drain the line. Disconnect the water distribution lines in the sink using a adjustable wrench. Use a basin wrench to loosen and remove the nuts holding the tap on the sink.

Turn the nut holding the P-trap set up counterclockwise to loosen it. Use an adjustable wrench to loosen and remove the nut holding the drain’s tailpipe set up. Disconnect the pop up waste assembly from the tailpipe. Pull the drain assembly out of the sink basin.

Clean out the countertop nicely with a marble countertop cleaner. You have to eliminate all symptoms of oil, lime scale and rust.

Cover anything in the area you don’t want coated with marble dust with vinyl sheeting held in position with tape.


Rub automotive finishing compound on the surface of the countertop with a wool pad. Let it haze over. Dampen the surface slightly. Sand off the finishing compound with 1,000-grit sandpaper. Sand by hand with a multipurpose tool. Maintain the surface damp. Be careful not to sand too intensely or you’ll remove all of the gel-coat from the countertop. Maintain the sanding level so the surface doesn’t develop any drops.

Rinse the whole counter and pouch with clear water. Dry it completely.

Apply another coat of automotive completing compound with a wool pad. Let it haze over. This time enthusiast the completing compound away with a buffing pad attached to a buffer.

Clean out the countertop with clear water.

Fixing the Faucet

Add the tap back into its holes. Secure it with all the nuts. Tighten the nuts , then flip one-quarter turn with all the basin wrench. Fasten the distribution lines back on the supply valves, making certain you connect the hot water lines into the hot water valve and the cold lines into the cold valve.

Put a bead of plumber’s putty around the drain hole in the sink. Insert the drain in to the drain hole. Tighten its nut from beneath. Attach the drainpipe into the drain collar, aligning it with the P-trap as you do this. Pull the nut onto the P-trap across the bottom end of the drainpipe to secure it. Reattach the pop-up assembly.

Turn the water back to the sink and then confirm that there aren’t any leaks. If there are, flip the leaky fitting no more than one-quarter turn and simmer for leaks.
