To paint ceramic tiles, clean and sand the tiles, then apply primer before painting. You need trisodium phosphate, rubber gloves, a clean rag, sandpaper, a sponge, a cleaning pad, primer, painter's tape, newspapers, a low-nap roller, a paint brush, denatured alcohol and water to complete this task.Continue Reading
Mix 1/2 cup of trisodium phosphate in a gallon of water. Put on rubber gloves, and apply the solution to the ceramic tiles from the bottom upwards using sponge. Let the solution loosen dirt on the tiles for two minutes, and use a cleaning pad to scrub the tiles. Rinse the tiles, and let them dry. Using a clean rag, wipe the tiles with denatured alcohol to remove dirt remnants.
Sand the tiles to remove the gloss for the new paint to stick. Avoid pressing too hard so you don't scratch the tiles. Wipe off the dust generated from sanding with a damp rag.
Mask and protect the surrounding walls from paint using tape and newspapers. Use the low-nap short roller to apply a thin coat of primer. Let the first primer coat dry, and roll on the second coat. Let the second primer coat dry.
Using a paint brush, apply the first coat of finish paint, and apply a thin coat of finish paint with the roller. Let the paint dry, and apply another coat of finish paint.
