5 Proven Methods For Removing Paint From Concrete Floors

The concrete surface is one of the hardiest options for inexpensive flooring, as it doesn’t require much upkeep but can be a tricky surface or rust stains to maintain.

The naturally porous, cleaned concrete surface tends to absorb paint stain, and liquids splatter over time. It can be difficult, but not impossible, to keep your concrete surface looking clean. 

Read on for our guide on removing chipped paint from your basement, garage, or workshop's concrete flooring below!

Removing Paint From Concrete Floors
  • Chemical Paint Strippers Method
    Mineral spirits and denatured alcohol are popular chemical paint removers for interior or exterior concrete surfaces, but such chemicals can be dangerous without proper ventilation.
  • Soy-based gel cleaners are less flammable and low in volatile organic compounds, making them easier to use and more environmentally-friendly. Simply apply the gel to paint, let sit, and wipe away, paint and all.
  • DIY Paint Strippers Method
    DIY paint stripping solutions are a cost-effective paint removal solution, but some home remedies aren’t quite as effective as store-bought strippers.
  • Methods include warm vinegar on a rag, hydrogen peroxide diluted with warm water, and baking soda mixed with boiling water. Latex and acrylic paints are the easiest to remove with home remedies, but we recommend more power for oil or epoxy paint.
  • Soda Blasting Method
    Similar to sandblasters, a soda blaster is a rapid paint removal mechanism that will be familiar to most home paint sprayers.
  • Just as sodium bicarbonate is a popular at-home paint remover, using a blaster with a baking soda mix is an effective way of removing paint or even removing oil stains off concrete floor. We recommend keeping the nozzles close to the ground for the best results.
  • Power Washing Method
    Power washing is one of the most effective ways to remove carpet and paint concrete surface stains. No chemicals or solvents required: Just intense water pressure is all you need with this method, making it fairly environmentally friendly.
  • Unfortunately, this method doesn’t work for hardier paints or very old stains. Power washing works best on new acrylic or latex stains.
  • Absorbent Paint Stripper Method
    If you’re looking for the best way to remove old paint stains from concrete surface rooms, this super-absorbent paint stripper works best on old floors. Simply mix equal parts of finely ground clay with a paint stripper into a thick paste, apply to the flaking paint, and let sit for a few hours. Scrub away with a scrub brush and repeat until clean.

Supplies Needed for The Job

Whether you have a concrete surface in your basement, garage, workshop, or outdoor patio, a little bit of paint can always improve its gray appearance if you choose the right color

However, concrete’s porousness and roughshod workspaces can often damage paint jobs. If you’re wondering how do you remove stubborn paint residue from your indoor and outdoor concrete floor, you’ll need the following:

  • Paint scraper or wire brush
  • Gloves
  • Goggles
  • Respirator mask
  • Oil or water-based paint stripper
  • Old paintbrush

How to Remove Paint from Concrete

  1. 1
    Scrape away loose paint - Start by using a metal paint scraper or wire scrub brush to scrape any peeling or chipping loosened paint.
  2. 2
    Remove loose debris - To get a clean finish, you’ll need a clean surface. Sweep or vacuum any particulates. For stubborn dirt, use a garden hose or power washer to clean the floor: Let dry completely before the next step.
  3. 3
    Put on protective gear - Set yourself up for success with gloves and protective eye-gear. If you’ll be using harsher chemicals, consider a respiratory mask and coveralls as well.
  4. 4
    Apply a paint stripper - Oil-based paint stripper works best for oil-based paints, and we recommend it if you’re uncertain which is on your floor. For latex or acrylic paint, use a water-based stripper. Apply with an old paintbrush and let sit, according to instructions.
  5. 5
    Scrape away the paint - Once you’ve allowed the stripper to sit for several hours until bubbling, use a wire scrub brush or wire brush to remove the resulting sludge in sections. Keep a trash bag or old newspapers on hand to contain the mess.
  6. 6
    Rinse the concrete - Using the hose or pressure washer once again, give your floor a generous spray. If stains persist, let the floor dry and repeat from Step 3 until satisfied.

Removing Paints Without Using Chemicals

If you’re wondering how to remove paint from concrete floor without chemicals, never fear. There are quite a few methods that don’t require harsh chemicals, just a little elbow grease.

A sharp paint scraping blade usually works well on smooth concrete floors, but its porous nature can retain stains even post-removal.

Sanding can also work, and even remove the top thick layer of stained concrete. But if you pursue sanding, be mindful of ventilation and always wear a respirator mask against inhaling concrete dust.

How to Remove Dried Splatters on Concrete

For dried paint splatters, start by clearing the surrounding area of debris or dirt and attempting to remove old paint with a scraper.

Remove any resulting flakes. If the splatter persists, use an old paintbrush to spread oil or water-based paint stripper on the stained areas.

Let sit according to instructions, and use a scraper or metal brush on the newly-softened splatters.

Rinse the area clean. Alternatively, combine the last two steps by spraying the splatters with a pressure power washer.

Also, remember to wear protective clothing during this task.

How to Remove Wet Splatter on Concrete

Speed is of the essence: Grab a rag immediately and, starting at the edges of the splatter, wipe towards the center and try "scooping" the paint into the rag to prevent spreading the stain further.

Next, mix one tbsp dishwashing liquid with 1-gallon of warm water. Dip a wire or scrub brush into the solution, and scrub at the stain until fully removed.

If the stain has slightly dried before you could remove it: Soak a rag in commercial paint thinner and place over the splatter for at least 30 minutes.

Next, use a paint scraper or wire brush to scrub the softened paint away, and clean the area with cold water.

How to Figure Out What Type of Paint is on the Concrete

Not all the paints are created equal, and some paint formulas can be more easily removed from concrete than others.

Learning how to remove acrylic paints from concrete floors, for instance, can be rather different than learning how to remove water based latex paint from concrete floors.

Latex, oil, epoxy, and acrylic all the paints are some of the most commonly found paints on concrete floors and they all have different drying times.

To determine which kind of paint spills is on yours, we recommend the touch test. Oil paints are smooth, while latex and acrylic paint often feel rubbery.

If you are removing paint from a concrete floor, try applying a small amount of paint de-glosser. Latex paint will either be removed or become tacky to the touch, while oil paints will do neither.
