- The first thing when refinishing a bathtub is to gather all the materials and equipment necessary to perform the task. You will need to decide what color you would like to refinish your tub. What chemicals or paint do you need and is it safe for your family to be around. You can go to your local hardware store and speak with a salesman about the many options you have to refinish. There are kits available with all the supplies but keep in mind tthat some paints may not adhere to the tub causing it to peel. You will want to be sure to thoroughly clean the tub and degrease it to be sure the tub is correctly prepared to receive the paint. To do this you can use an soft wire scrubber and a limeaway product. Next the tub will need to be sanded to remove any rough edges and rust. Besure the sandpaper is wet so that the sand grit and grime easily washes away as you are working. When finished, rinse, and completely dry. Next you will want to caulk around the tub with clean fresh caulking. Allow this to completely dry. Read caulking label to determine the amount of time necessary. Next you will want to use blue painters tape to tape the edges around the tub and fixtures so not to get any paint onto the tile or the walls of the tub area. Stir paint completely and smoothly. Mix paint with epoxy to be sure paint will adhere to the tub. Apply the mixutre to the tub in long thin coats to be sure there are no bubbles or residue left behind. If there are some small bubbles, these will disappear as the mixture dries. Be sure to paint in one direction being careful to not leave lines in the paint. Allow the first coat of mixture to dry for a hour then apply the second coat. Repeat as necessary until all areas of the tub are covered and refinished to your expectations. Clean your work area and allow to dry completely. Preferrable over night.
