Ideally, you can apply paint to your plastic kitchen sink to restore it to its glory. Apply paint to the surface of your bathroom or kitchen sink to refinish it and make it seem new again.

What Paint Can You Use On A Plastic Sink?

The best paints to use on your plastic kitchen sink are Kyron Fusion for Plastic, Rust-Oleum Paint for Plastic, and EP-Acrylic paint.

Most hard plastics are compatible with EP-Acrylic paint, Krylon Fusion for Plastic, and Rust-Oleum Paint for Plastic, so they should work whether your sink is acrylic, polypropylene, fiberglass composite, or any of the other plastics that are commonly found in laundry sinks these days.

Because Krylon and Rust-plastic Oleum's paints are only available in spray cans, dealing with overspray is crucial.

Other than the sink, you'd need to completely cover all surfaces where paint droplets could land. Remove the paint from the walls, the floor, the cabinets, and even the drain trim and faucet. Wear goggles and a mask.

Rust-Oleum Specialty Plastic Primer and EP-Acrylic paint, brush-on paints that adhere to plastic and allow you to use regular paint as a topcoat, are both less messy options.

Factors to consider when selecting your Plastic Kitchen Sink’s Paint

  1. To properly adhere to the surface, the ideal paint should have a high adhesive capacity. Your paint is more prone to chip if you don't have this talent, which means you'll have to make more frequent repairs.
  1. Use a paint that only takes a few minutes to dry and cure. It will take fifteen to thirty minutes for the normal ones to completely dry. To avoid being caught off guard, consider how long it will take for the paint to cure once you've applied it.
  1. Versatility is an important feature to seek in any paint. The correct paint should be able to be applied to any surface with ease. It should also be resistant to corrosion and water.

How To Paint A Plastic Kitchen Sink

Step #1 – Clean the Sink Thoroughly

Thoroughly clean the sink. Use a powerful cleanser designed to remove oil, soap scum, and mildew. Clean every inch of the sink to ensure that nothing gets in the way of the paintwork. Rinse and dry the sink thoroughly.

Step #2 – Smoothen the Plastic Sink

Using a palm sander and sandpaper, rough up the surface of the sink. The palm sander vibrates gently, which aids in roughening up the plastic without leaving deep scratches on its surface. Remove any loose debris from the sink and thoroughly dry it.

Step #3 – Tape out the Necessary Parts

To protect the sink's drain, edge, and any faucets that come into touch with its surface from the paint, tape them off.

Step #4 – Paint the Sink

Using a paintbrush, apply EP-Acrylic paint on the sink. This unique paint will bind with the sink's original plastic to create a smooth, glossy surface. Apply at least two coats, allowing the paint to dry completely in between. Allow 24 to 48 hours for the paint to set before utilizing your new sink.

Sealing the Paint After Painting

A clear acrylic sealer adds an extra layer of protection to your freshly painted plastic surface.

You don't have to use the sealer, but it can help the results last longer, especially if you're painting something that will be exposed to the elements. To make the job easier, you can use a spray sealer.

Before applying the sealant, let the paint dry completely. Spray it on with the same consistency, smoothness, and overlapping sprays that you used for the paint.

One coat of sealer is normally sufficient, but if the object is subjected to extreme circumstances, you may need to apply more. Allow each layer to thoroughly dry before applying the next.

How Do You Remove Paint From A Plastic Sink?

  • Begin by sprinkling WD-40 on the paint splash.
  • Allow a few moments for the WD-40 to take effect.
  • When the paint begins to melt, try to remove the splatter using a plastic ice scraper.
  • If the paint is flush with the surface and won't come off with a scraper, liberally use WD-40.

Additional Advice and Suggestions

  • Older paintings may take a bit longer to remove, but the procedure above will work for them as well.
  • Because WD-40 does not dry out, you can apply a thick coat and leave it to soak overnight for extremely persistent paint splatter. This should soften the paint, allowing it to be removed more easily.
  • If WD-40 fails to remove the paint, you may need to use a paint remover. Examine the labels carefully, or ask a hardware shop employee for assistance in locating one that will safely clean the plastic surface.
  • Other cleaning agents that have been useful in removing stains and marks from plastic kitchen sinks include soft scrub and Bar Keeper's Friend. They're minimally abrasive and suitable for a wide range of surfaces.
  • Consider it a sign of character and usage if the paint won't budge. Kitchen sinks are designed to handle all of the filthy stuff that we wouldn't let touch any other house surfaces.
  • Rub the area with a cotton ball or soft cloth dampened with rubbing alcohol if it's latex paint. It will sever the paint and make it possible to remove it.
