Bathtubs see a lot of wear and tear due to frequent use, so you may occasionally need to do bathtub resurfacing. Read on for information about how to do this project yourself.
Step 1: Learn About Your Tub
Determine what type of tub you have installed, as this will help you in choosing the products you need for resurfacing. Older-style bathtubs are usually made of porcelain on steel, enamel or cast iron. Contemporary bathtubs and showers are generally made of acrylic, plastic or fiberglass.
When you know what makes up your tub, purchase a kit with all the material you will need for resurfacing. If you like, pick up individual products like paint, thinner, epoxy and sandpaper.
Step 2: Prepare the Area
You will be working with strong chemicals that can be harmful to you. It is important to work in a well-ventilated area, wearing protective clothing, goggles and strong rubber gloves.
Step 3: Clean the Bathtub
Use 500-600 grit wet to dry sandpaper to remove any loose caulking from the sides. If you have a DIY kit, it will include some chemical solutions that will remove any excess oil and soap buildup on the surface. Let it soak for a few minutes, and then thoroughly rinse. Scrub again, rinse and wipe the surface to let dry.
Step 4: Apply the Prime Reducer
Apply the prime reducer to prepare the surface for the actual primer. If there are any scrapes or other damages to the surface of the tub, they will show up now. Repair and fill the spots with putt, as well as the area around the drainage hole.
Let the putty dry and set for at least an hour. Sand the damaged areas and add another layer of prime reducer. Let this stand for a few minutes, and then pat it dry with the old towels.
Step 5: Add Primer
For this stage, use a mask or respirator and make sure the bathroom is well-ventilated. Fumes arising from the primer spray can be very harmful for you.
Mix the chemicals for the primer together in the proportions specified by the manufacturer. Use a spray gun to evenly apply the first coat of primer. Don’t fuss too much about any runs, as they will be covered over by subsequent coats.
Let the first coat dry for at least 3 to 4 hours. With steady, even strokes, apply the second coat—and if necessary, a third. After the top coat has been applied, you need to wait at least 48 hours for the primer to harden, to give it a glossy new re-finish.
