One thing that most homeowners will need to do from time to time is to reglaze a bathtub, sink, or toilet. DIY reglazing is much less costly than hiring a professional and the results can be just as pleasing.
Reglazing a bathtub is one of the more common uses for this skill, and DIY reglazing will save a bathtub from needing to be replaced, which can be extremely costly. Reglazing a tub to cover any stains or chips can also add value to a home.
Before starting a DIY reglazing project, it is a good idea to remove any loose articles from the bathroom that could be damaged, stowing them in cabinets or out of the room. This includes items on the walls, towels, and any decorative items.
It is also very important to be sure that the bathroom has adequate ventilation. If there is no window in the bathroom, or it can not be opened, a ventilation system can be rented and set up prior to beginning the project.
If you are starting a DIY reglazing project on a bathtub, any trim plumbing located near the bathtub will also need to be removed. These will include the spout, showerhead and the overflow cap. The caulking and grout that borders the bathtub will also have to be removed. Make sure to remove any mess from the removed items to make sure that they will not settle into the new glaze.
Use an industrial-strength cleaner to clean out the tub, then rinse and use a 120 grit sand to remove anything that may be stuck to it. Dry the tub thoroughly, then wash the bathtub out with hydrofluoric acid, letting it stand for about 10 minutes. Then rinse with cold water, wash with the industrial cleaner again, then dry. There should be no moisture left anywhere.
Reglazing the Bathtub
The bottom and ledges of the tub should be filled carefully with a body filler. This may need to be repeated several times, depending on the condition of the bathtub. After the DIY project is over, any access body filler would be difficult to remove, so be sure to apply it correctly.
Before going any further with your DIY reglazing projects, mask the floor and all of the bathtub borders with a wide masking tape. Anything else in the room, including sinks, the vanity, etc., will need to be covered with plastic sheeting. When everything in the room is securely covered, sand the body filler.
Once it is smooth, clean everything with a shop vac and then tack cloth the entire bathtub. An epoxy product should then be used to prime the bathtub. This should then be left to dry for as long as the label suggests.
Tack cloth the bathtub again. When this is done, it is time for the DIY reglazing. The glaze will have to be applied with a spray gun according to the manufacturers suggestions. When it has been applied, clean out the spray gun and leave the new glazing to dry overnight.
The next day, the fixtures can be replaced, and the masking tape can be removed. The borders of the bathtub will need to be re-caulked and re-grouted. Before using the bathtub, be sure that the glaze is dry, which can take as long as 48 hours.
