How to Clean Garage Floors Before Painting

Putting in the time to repaint your garage floor is a big home project. You want to make sure you properly prepare it so your time and efforts do not go to waste. This means putting in the work beforehand to ensure that the space is ready for coats of paint. You’ll need to clear out areas that will be painted, cover any low electrical outlets, and, most importantly, do a deep clean of your garage floor.

Our garages deal with a variety of wear and tear over the years from grease spills to leftover sawdust to cracked surfaces. You will want to address each of these problems before painting. Doing so will make sure your paint goes on smoothly.

Equipment for Garage Cleaning

Our garage floors are really good at building up dirt, oil, and grime over the years especially if it is not regularly cleaned. To begin tackling these issues, you’ll need to have the right equipment. The basics you will need include something for scrubbing like a deck brush or push broom, degreaser solution or laundry detergent, and a garden hose.

Those who are dealing with tough stains or cracks can also use epoxy paste, sawdust or cat litter, and vinegar or trisodium phosphate (TSP). A pressure washer can also be a helpful tool to help push out any dirt. These are usually available for rent from a local hardware store.

Initial Cleaning

The first thing you’ll have to do is scrub the floor as clean as possible. Mix your cleaning agent into a bucket of warm water, pour it over areas in your garage, and start scrubbing. If your floors are extra dirty, you can let the solution soak for 10 minutes before starting.

Make sure you rinse everything out while the floor is still wet. Doing so after the floor has dried does not help with removing the dirt and contaminants in the concrete.

Removing Stains

After your first round of cleaning, you can move on to any visible stains on your garage floor. Removing these will help the paint go on easier and last longer.

Oil and Grease

Oil and grease can be removed by using degreaser on the oil spot. You can also cover the stain with sawdust or cat litter which will help absorb the excess oil and grease before using degreaser. Scrub and then rinse.

Rust

Small spots of rust can be removed using vinegar. Just let it sit on the spot for a few minutes and scrub. Trisodium phosphate and boiling water work well for larger areas of rust. Just let the solution sit and then scrub it off.

 

Fill in Cracks

Use epoxy paste to fill in any cracks you see on your floor. This will help prevent it from looking dented once your coat of paint is applied. Scrap off any extra paste and sand it off once it is completely dry.
