Modern porcelain toilets are ill-suited for adhesion and require tedious abrasion techniques to condition them for painted finishes. If you need to paint a wood toilet, you're in luck, as wood surfaces are much more suited for paint. Prepare the toilet in the appropriate manner, or the wood will reject its new finish. Apply a particular paint, formulated to remain durable under duress. Use the proper paintbrush, or your new finish may dry marred with unwanted brushstrokes.
Wash the wood toilet with a water-based cleanser, using a coarse sponge. Rinse the toilet with wet rags. Wait 24 hours for the toilet to dry.
Sand varnished toilets until the finish appears dull. Sand with the toilet wood grain, or splintering will result. Wipe the toilet down with tack cloths. Skip this step if the toilet is unvarnished.
Protect surfaces adjacent to the wood toilet by covering each with painter's tape, dust sheets and/or masking paper.
Apply acrylic latex primer to the wood toilet, using a synthetic polyester paintbrush. Brush along with the toilet wood grain. Apply gentle pressure. Watch closely for flaws and smooth them as they become apparent. Allow three hours of dry time.
Wash acrylic latex primer from the polyester brush, using fresh tap water.
Apply acrylic enamel to the primed wood toilet, using the clean brush. Brush along with the toilet wood grain. Apply gentle pressure. Watch closely for flaws and smooth them as they become apparent. Allow three hours of dry time.
Use an oil-based primer on stained wood toilets. Be sure to use an oil primer, specifically engineered for use with acrylic paint.
Never paint an unprimed wood toilet, or the finish will peel. Don't use latex paint on a toilet, as it will ultimately chip and fade. Don't use a nylon brush to paint a wood toilet, or your new finish may dry marred with unwanted brushstrokes.
