How to Reglaze a Bathtub For Cleaning and Durability

Prepare the room and remove all portable items. Cover up the floors and other surfaces you wish to protect with canvas tarps and hang plastic sheeting over each wall with painter's tape. Ventilate the bathroom as much as you can; open any windows and doors in the room and use a circulating fan.

Cover the opening of the bathtub faucet with overlapping strips of masking tape. Fold a double-layer of newspaper around the faucet so that it is entirely covered and wrap the whole thing in masking tape. Cover the faucet handles and any other metal hardware in the same manner.

Transfer the etching liquid to a painting pan, being careful not to spill any. Use a paintbrush to coat the entire tub in a thin, even layer of the etching liquid. Let it sit for 20 minutes.

Wipe down the edges of the tub well with a damp rag. Dump buckets of water into the body of the tub to rinse the inside thoroughly. Rub the entire tub in circular motions with a soft towel to dry it off.

Fill the paint sprayer with the liquid primer. Select a slow and steady speed and paint the tub with an even layer of primer from end to end. Let the primer set up for half an hour and apply a second layer.

Allow the primer to dry while you wash and dry the container of the paint sprayer. Fill the container with the glaze component. Paint two coats of glaze onto the tub in the same manner that you painted on the primer.

Repeat Step 6 with the topcoat component. Apply five layers of topcoat, letting each coat sit 30 minutes before adding the next. Wait three days and unwrap the tub hardware.
