Glazing a bathtub or sink can make it look like new again and the cost is a fraction of what it would be to replace bathroom fixtures. Glazes come in a variety of colors. You can also choose finishing textures such as speckle, stone, gloss, satin or matte. It is also possible to have your glaze custom matched to the color of your existing bathtub or sink. When there is only a small area that needs to be repaired, glaze can be blended into the original surface.
Things You'll Need
- Spray-on glaze
- Industrial strength cleanser
- Drop cloth
- Masking tape
- Hydrochloric acid
- Porcelain filler
- Epoxy primer
- HVLP turbine sprayer
Address any plumbing issues such as leaky taps or pipes before glazing. Have a plumber repair or replace any plumbing parts as needed. Remove shower doors or any tracks that are connected to the sink or bathtub as well as any items hung on the wall. Cover everything that is not being glazed with plastic or a drop cloth and tape it securely using masking tape. Ensure the bathroom is well ventilated to prevent breathing in unwanted fumes.
Remove the existing caulking around the bathtub. Clean your bathtub or sink with industrial strength cleansing solution. Soak the bathtub and sink with a wash of hydrofluoric acid. Let the acid sit for a couple of minutes and then rinse completely using cold water. Sand the bathtub while it is still damp. Vacuum any remaining dust.
Put waterproof body filler into any chips or cracks and allow it to dry. Sand the filled areas until smooth. Remove any dust with a cloth. Apply one coat of epoxy primer and allow it to dry completely. You can spray it on a using HVLP turbine sprayer. Spray on another coat of epoxy primer and allow it to dry. A third coat of epoxy primer is optional, but ensure the bathtub or sink is completely dry before each coat.
Spray on one coat of glaze evenly over the surface of the bathtub and sink using the spray gun. Allow it to dry completely. Spray on up to three more coats of glaze.
Allow the glaze to dry for 48 hours or longer. Caulk the edges around the bathtub to seal them. Allow the caulking to cure before using the bathtub.
Tips & Warnings
- Safety goggles and gloves will protect your eyes and skin.
- Glaze coatings may be hazardous to breathe, so ensure the bathroom is well ventilated. People who have asthma or respiratory conditions should avoid being in the house or on that level of the house when the re-glazing is being done.
