How to Prep a Pool for Painting

What You'll Need
Heated pressure washer
Floor squeegie
Safety goggles

Inground pools are usually made of cement with a safety layer of sand mixed with paint. Sometimes this layer starts to peel and fall apart, so you may have to get the old paint off to ready it for the new pool paint.

It could just be that you just built an inground pool, and you need to get it ready. It works the same way. Since most inground pools have drains in them, you can get away with using water to ready the pool’s walls for painting.

Step 1 – Sandblast

The first thing you must do to get your pool ready for painting is to sandblast the interior cement. You have to take off the paint that’s there and it’s best if you don’t use chemicals because you don’t want anyone to end up with those same chemicals on (or in) their skin when they go swimming in your pool.

So start up your sandblaster and begin at the sides, standing up at ground level and pointing down. Spray the walls and work your way down to the floor, taking off the paint with the force and grit of the sandblaster.
Once this is finished, you should have no paint left in your pool. Now it’s time to use the pressure washer.

Step 2 – Pressure Wash Pool

Use the hottest water you can with your pressure washer and thoroughly rinse the walls down. Practice the same wall-down technique as you did with your sandblaster, and you should rinse any little bits that might have been left down into the bottom of the pool. Do the same thing to the floor as you did with the sandblaster, kicking up everything you can from the floor of the pool.

Make sure there’s a little bit of standing water in the bottom of the pool, and get ready to use your floor squeegie to get the pool ready for its next paint job.

Step 3 – Squeegie and Clean

Now use your floor squeegie to pull all of the paint chips into a pile away from the drain. This will allow you to scoop up all of the gunk that’s sitting there without it clogging the drain system. You may need a shovel or big dust pan to get the paint chips out of the pool, but whatever you do, don’t let them go in the drain.

You’re all finished! Your pool should be ready to dry and thereafter receive a brand new coat of paint with sand mixed in for the slip-proof texture. You can now go inside and relax—it’s no fun watching cement dry.
