Your acrylic kitchen sink takes a lot of abuse with daily use. Through time, it may start to show wear and tear. Instead of replacing it, which can be costly, you can resurface it yourself with some elbow grease and the right tools.
Step 1 - Cleaning
It is important to clean the sink thoroughly so the paint adheres to all of the surface. Use a degreaser to clean the sink. Use your cleaning brush to scrub around the edges to be sure any greasy debris is removed. Rinse well to remove all of the degreaser and dry thoroughly. You'll want to protect the areas around the sink next to avoid getting any primer or paint on it.
Step 2 - Sanding
You will need to sand all of the existing finish off of your acrylic sink. That's why an electric sander will work best for this project. Your sink will have a coarse feel to it when you're finished. This is necessary for the primer to adhere well. When your surface is completely sanded, you need to protect surfaces that you don't want to get paint on.
Step 3 - Cover Surfaces
Using heavy paper, trace a pattern to go around your sink, cut it out and tape it around the edges, leaving your sink surface exposed. You can tape additional paper to that piece to protect the wall behind the sink and the counter tops. Use the paper and tape to cover your kitchen sink fixtures as well. After you have everything covered, you will be ready to apply primer to the sink.
Step 4 - Apply Primer
Because your sink needs to be durable, you will apply epoxy primer. This will also fill in any scratches or dings on the surface, giving you a smooth surface when the paint is applied later. Load the paint sprayer paint chamber with the primer and put on the ventilator mask. Spray the primer side to side to get an even coat. You can add a second coat to be sure you have all of the surface thoroughly covered. Allow the primer to dry approximately 30 minutes before applying the paint. While it's drying, clean the paint chamber for the next step.
Step 5 - Paint
Again, you will need to wear your ventilator mask. Fill the paint sprayer chamber with the epoxy paint. Use the same side to side application method as you used for applying the primer. It's recommended that you apply two coats of epoxy paint in this step for added durability. Clean the chamber of the paint sprayer again, while allowing the paint to dry for 30 minutes. Your next step will be to finish with acrylic top coat.
Step 6 - Top Coat
The top coat adds a shine to your sink and gives it a new, professional appearance. Load the paint sprayer once again with acrylic top coat. Apply as you did for the primer and paint. After it dries, you will want to let it cure, or harden. Do not use the sink for 24 hours to allow this process to take place. Go out to dinner and enjoy your new sink tomorrow and for years to come!
