What is the best way to paint over brown wall tiles
Wash your tiles first - then use BIN primer (it will adhere to your tiles). Then paint with the paint of your choice. BIN is a primer.
After thousands of sq. ft. of tile, and thousands of gallons of paint, (not together) and with all due respect to you and others; this is kind of like a CAN I? question. Tile is essentially glass. Certainly you CAN probably paint over, but may never truly be satisfied with the result, especially over any long term. Also with no offense at all, and not needling you over a misspelling, I had to chuckle at Pinting. I've probably done a lot of that too, and in fact probably while on or over tiles. Steven Wolf
