Painting Ceramic Tile

[Moonshine]

I recently purchased a new home that has tile in the master bath. Floors, tub surrounding, vanity backsplash and shower. I really like the majority of the tile, however every third tile in certain locations has a really odd looking decorative symbol in it. They are the first thing you notice when you enter the bath. I was wondering if I can paint over the decorative tiles or if I have to knock out each tile and replace individually. Obviously painting would be less time consuming, however I am not sure if it will work. Only the tiles in the shower would be in contact with moisture, so replacing those may be the best anyway. If anyone has experience painting tile I would sure enjoy hearing their comments.

Thanks!

I did an internet search, and came up with these instructions for you. The author explains it much better than I could.

Preparing the Tile for Paint

As with most painting projects, preparation is the most important part. The goal is to create a surface that the paint will stick to. Since we have already established that most paints will not stick directly to the slippery tile surface, we need to get rid of that shine. The first step is to clean the tile vigorously with a commercial tile cleaner. Make sure you use one with a mild abrasive. Not only will this remove all of the buildup from the tile and make it nice and clean, but the abrasives will begin to break down the shiny surface.

At this time, also make sure that anything that might deteriorate underneath your paint job is addressed. Crumbling grout, mildew stains, and cracked tiles should all be taken care of now. You can't go back and address them after you paint unless you want to repaint the entire thing.

Once you are confident that the surface is clean, you need to get a little more aggressive about taking that slippery shine off of the tile. The best way to do this is with a hand held orbital sander. Use a 220 grit sandpaper. This will be course enough to remove the gloss, but still fine enough to prevent you from leaving any marks that may show later through your paint. If you don't have an orbital sander, you can do it by hand - it will just take a little longer.

After every surface that is going to be painted has been sanded, including the corners, make sure that all of the dust is thoroughly removed. I know sanding is tedious and is generally not very much fun, but I can't overemphasize how important this step is. If you skip the sanding or only do it half-heartedly, the paint simply will not stick.

Prime and Paint

Now that you have a freshly sanded surface that is dry and free of dust, you have the perfect foundation for a good paint job. By using a high quality and high adhesion primer, continue to build the base that your paint will be applied over. This is not the project where you want to skimp on paint costs. Don't buy the cheap primer - you need a strong bond in order for this to stick to the tile. Use an oil based product, as you will be using an oil based paint for the finished coats.

Apply the primer using a brush to cut in the corners and then a short napped roller (1/8") to apply the primer to the flat surface. Go slowly and make sure you don't leave any lines caused by paint squeezing out of the edge of the roller cover. These will show through later when you apply your finish coats. Allow the first coat of primer to dry for the amount of time recommended on the can, and then apply a second coat.

Once the primer is dry, take a fresh sheet of 220 sandpaper and make a very light pass over the primed surface. You are not trying to remove the primer, you simply want to remove any small burrs that may have risen out of your roller cover and make sure that the surface is perfectly prepared to receive paint.

Some people suggest that you can use latex paint for your top coat. I, however, would recommend that you use oil. It is messier, takes longer to apply and longer to dry, but when it dries it provides a very durable finish. Latex paint often dries with a fairly soft, rubbery feel. If you were to bump it with something hard, the chances that it could peel right off are pretty high.

Use an oil based semi-gloss or high gloss alkyd for your top coats. Apply several thin coats instead of trying to do one thick one. You want to build up the strength of the paint adhesion by adding multiple lightweight layers, not one heavy one.

You will need to have paint thinner on hand in order to clean up the oil based primer and paint, as well as a pretty good sized supply of rags. Though it may be a little extra work, using the oil based product on your tiles will give you a much higher quality finish and in the long run, you will be glad that you did.

Whatever you chose to do I would suggest that you go to a real paint store and a real tile store to get your advice and materials. The folks at the big box stores just aren't likely to have the experience. Abbott and the Tile Shop would be on my list.
