Top Tips for How to Paint Over Ceramic Tile in a Bathroom

It seems a shame to tear out perfectly good tile from a bathroom just because you don't like the colour, doesn't it? So, what's the alternative? Can you paint over ceramic tile?

Painting Over Ceramic Tile

You can paint over ceramic tile walls in a bathroom, but you will lose some of the interesting characteristics of tile since the grout lines will be the same colour as the tile.

First, let's talk about what you can and cannot paint. I would not recommend that you paint any tile surface that gets wet repeatedly.

If you try to paint your shower surround or even your tub itself, you will be cleaning paint chips out of the bottom of your tub within a matter of weeks. It just won't stick.

There are professional services available that will paint your ceramic appliances and fixtures. Things like your antique claw foot tub, your toilet, and shower stall can be painted with a highly specialized product that requires a good deal of skill to use.

But in this post, what we're talking about is painting wall tile or countertops that see everyday use but don't get drenched all the time.

Preparation is Key

As with most painting projects, preparation is an essential 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 buildups from the tile and make it nice and clean, but the abrasives will begin to break down the shiny surface.

Preparing the Ceramic Tile for Paint

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 fix 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 the tile. The best way to do this is with a handheld orbital sander. Use a 220 grit sandpaper. This is 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 could 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, ensure 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 Ceramic Tile

Now you have a freshly sanded surface that is dry and free of dust. This means you have the perfect foundation for a good paint job.

Using high-quality and high adhesion primer, continue to build the base that you will apply your paint 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 for this to stick to the tile. Use an oil-based product, as you will be using 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 be sure you don't leave any lines due to 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 very light passes over the primed surface. Don't forget; you aren't 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.

Top Coat

Some people suggest that you can use latex paint for your topcoat. But oil is usually a better choice. While it is messier and takes longer to apply and longer to dry, it provides a very durable finish when it dries. Latex paint often dries with a reasonably soft, rubbery feel. If you were to hit it with something hard, the chances that it could peel right off are pretty good.

Use an oil-based semi-gloss or high gloss alkyd for your topcoats. Apply multiple 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.

Make sure you have paint thinner on hand 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.
