How to Reglaze a Bath Tub

by HomeRepairExpert.com
There will come a time when your bath tub will lose its glaze after years of exposure to hot and cold water. Before you buy a new bath tub, consider reglazing the old one. It is cheaper and easier than installing a new bath tub. Reglazing your bath tub wouldn't require you to remove bathroom tiles or tinker with the plumbing. In fact, the whole process may take only three to four hours.

  • Industrial cleaner
  • Scraper
  • Sander or sandpaper
  • Electric dyer
  • Waterproof body filler
  • Masking tape
  • Gloves
  • Goggles
  • Spray gun
  • Waterproof epoxy primer
  • Aliphatic acrylic urethane
Make certain that your bathroom is properly ventilated to prevent the accumulation of fumes from the chemicals to be used in the reglazing process.

Use an industrial cleaner to remove stains and dirt from the surface of the bath tub.

Use a scraper to scrape off any remaining glaze residues on the surface of the bath tub and wash it down with cold water.

Sand down the bath tub with a sander or sandpaper while it is still moist. Wash down the bath tub again and let it dry. You an also use an electric dryer to speed up the drying process.

Apply a waterproof body filler to areas that may be excessively damaged. This will ensure that the bath tub has a uniform, smooth surface.

Use masking tape to cover areas around the tub that you want to protect from chemical sprays.

Wear gloves and goggles to protect yourself from chemical fumes. Use a spray gun to apply three layers of a waterproof epoxy primer. Wait 15 minutes before applying each new layer.

Let the primer dry for at least 15 minutes before applying three to four layers of an aliphatic acrylic urethane. Let the coat of glaze dry and cure for at least 48 hours.

Tips and Warnings

  • Avoid using epoxy primers that require the use of an acid solution (such as hydrofluoric acid) for etching. This method can cause long-term damage to the bath tub.
  • Steer clear of wipe-on primers for bath tub reglazing; they are meant for use on glass only. They may be cheaper than spray-on primers, but they break down within a couple of years.
