Does White Spirit Remove Paint from Concrete?

If there’s been an accidental paint spill on your concrete drive or the concrete patio in your backyard has an unsightly paint stain, one of the best ways that you can choose to remove it is by using White Spirit.

This cleaning agent consists of petroleum distillate and is primarily used as a paint thinner and solvent, although many have found that it works pretty great at lifting dried paint from a variety of surfaces, too.

To do this, ensure that you are dressed in protective clothing as, though White Spirit has a moderately low acute toxicity by inhalation, there is still a chance that it could cause irritation.

Once you have done this, pour the White spirit directly into the stain and leave to soak for a few minutes, as this will allow the solvent to delve deep into the porous surface and begin lifting the paint.

Then, with a scrubbing brush, scrub the paint in circular motions until the paint has been lifted. If there are any stubborn spots, you may need to repeat the process.

Keep in mind, as White Spirit is a mild solvent, it means that it may not be the best at removing paint from surfaces that are very porous and absorbent, such as concrete and wood.

For this reason, if you find that you are struggling to remove dried paint with White spirit (particularly oil-based paint), you may need a stronger solvent for the job.

Does muriatic acid remove paint from concrete?

Muriatic acid is very good at lifting dried paint from all types of surfaces (not just concrete) but runs the risk of damaging the surface of the concrete if it is left to sit for too long.

A slight variant to hydrochloric acid, muriatic acid is essentially a diluted solution of hydrochloric acid and can contain impurities within the mixture such as iron.

Just like hydrochloric acid, muriatic acid can be purchased at many home improvement or hardware stores and used to remove stains and dirt, hydrochloric acid.

Read on to learn how to remove paint from concrete with this type of acid:

  1. Prepare: Before you get to work, the first thing you’ll want to do is prepare both yourself and the area of concrete that you are going to be applying the muriatic acid. Prior to stain removal, many people like to clean the concrete surface as much as possible in order to optimize the efficacy of the muriatic acid by power washing, although you could just as easily take a sponge and some warm water. After preparing the concrete, you should then get changed into your protective clothing and gear, as muriatic acid is powerful enough to damage both clothing and skin.
  2. Ventilate: This step will be especially important if the concrete is in an interior space, such as the basement. Muriatic acid can release powerful fumes that can cause long and short-term health conditions, so you should make sure that, besides your protective gear, you have a steady airflow traveling through the area.
  3. Mix the solution: After you have done this, mix a solution of 9 parts water and 1 part of muriatic acid into a water bucket. To avoid getting the acid anywhere it shouldn’t be, pour the water in first, and then gently pour in the muriatic acid.
  4. Pour the solution: Once you have safely created your mixture, carefully pour the solution directly over the dried paint stain on your concrete surface.
  5. Scrub: Keeping in mind that the acid can cause damage to the surface if left for too long, immediately begin to scrub the paint stain. You should notice that the paint begins to lift after a few moments – though this could take several scrubs before you begin to notice anything happening!
  6. Rinse: After around 5 minutes (or your own judgment) rinse the area you have poured the muriatic acid thoroughly in order to remove the area of any acid.
  7. Repeat: After you have done all of the above steps, your paint stain should have been all removed.. However, if you have some stubborn areas that didn’t lift the first time, you may need to repeat the process all over again.

Will acrylic paint come off concrete?

Yes, acrylic paint will come off of concrete.

The great thing about acrylic paint is that it is water-based, which means it will be much easier to remove than oil-based paint, while the great thing about concrete is that it is very durable and can withstand rigorous cleaning.

However, when it comes to lifting paint from the surface of concrete, the main key is to focus on “pulling” the paint from the surface, which is full to the brim with pores and holes.

Follow the steps below to get rid of the acrylic paint:

  1. Remove excess paint: Scrape as much excess paint from the surface as possible with a paint scraper, knife, or even razor.
  2. Soak in acetone: Saturate the dried acrylic paint with acetone, and allow to soak for 5-10 minutes.
  3. Scrub: After giving the paint time to soak in the acetone, then begin scrubbing it with a bristly brush.
  4. Apply paint stripper: If there are some stubborn spots that won’t lift, saturate them in the paint stripper.
  5. Clean: When all the paint has been cleaned off of the concrete, wash it down with water and soap.

Will paint thinner remove wood stain from concrete?

Yes, paint thinner can be used to remove a wood stain from concrete, as it is a powerful chemical solvent that has the power to seep deep into porous surfaces such as concrete.

For the best results, we recommend combining paint thinner with baby powder (or even kitty litter if you don’t have baby powder).

The reason for this is because both products have the ability to “draw” out deeper layers of the stain, which makes both an ideal first step prior to applying the paint thinner.

After doing this, you can then proceed to further saturate the wood stain with paint primer, and then use a bristle brush to scrub the area until the wood stain has been lifted.
