Before You Start – The most effective way to remove paint off inside brick is to apply a non-caustic paint remover, scrape, and then brush. Removing brick off the outside of a full home or structure is a laborious, time-consuming physical task, which is why it is much simpler to say than to perform; nevertheless, an excellent paint stripper can make the process considerably less laborious.
Pressure washing and sandblasting can harm the interior of your home. Either procedure can irreparably pit or chip the brick. No paint remover will do everything for you, but some will do it more effectively (and safely) than others. Make certain that your paint remover does not include any hazardous substances, such as methylene chloride (commonly known as dichloromethane or DCM) or N-methylpyrrolidone (NMP).
For vertical surfaces such as walls and fireplaces, choose a paint remover that is gel-based. Gel strippers adhere to vertical surfaces more effectively and are applied in heavy coatings.
How can you remove paint that has dried on brick?
Trisodium Phosphate – In many instances, paint may be removed quickly and inexpensively by using a trisodium phosphate solution and washing. To produce the solution, combine 1 gallon of water with 12 cup of trisodium phosphate. Then, using a scrub brush immersed in the solution, clean the brick to remove the paint splatters.
- When scrubbing brick, avoid using a particularly abrasive wire brush, since this might harm the brick and mortar.
- Choose a firm brush with nylon or brass bristles instead.
- Protect the surrounding area of the brick with drop cloths.
- Combine this trisodium phosphate with one gallon of warm water.
- Trisodium phosphate is dissolved by stirring the liquid.
With this brush, apply the trisodium phosphate solution to the paint splatters and scrape. Wear eye and hand protection when working with trisodium phosphate.

When dealing with trisodium phosphate, be cautious to use safety gloves and goggles. Additionally, drop cloths should be used to protect the ground and other surfaces in your working area.
Put on safety goggles, a face mask, and work gloves to prevent exposure to the stripper’s chemicals and fumes. Brush the paint remover for masonry liberally over the brick wall, beginning at one corner and moving outward and downward. Reposition the ladder to cover the whole top of the wall with stripper before moving on to the next area.
- Repeat until every brick has been coated.
- Wait the manufacturer-specified period of time.
- Then, beginning at the top of the wall once more, remove the masonry paint remover with a brush with firm bristles.
- Paint will flake and peel off in clumps; continue to wear protective gear.
- Using the brush, scrub the entire wall to remove as much paint as possible.
To remove paint and the stripping compound from the brick wall, wash it with cloths and warm water. Permit it to air dry. To remove stubborn paint, reapply paint stripper to the stonework. Allow the substance to rest on the brick and scrape again. This process may need to be repeated many times to remove the majority of paint from the brick wall.
Repeat the procedure of rinsing to eliminate the stripper. Spray white vinegar on the brick wall and scrape away any leftover paint residue using a clean brush. Rinse the object with water. The use of high-pressure washing should be avoided since it can rapidly degrade the surface of bricks. Certain caustic chemical solutions can cause surface failures and alter the color of aged bricks.
The consequent rapid degradation is likely to necessitate extensive repairs.

How can paint be removed off brick without using chemicals?
Prepare Trisodium Phosphate Solution – In a clean bucket, combine one gallon of warm water and one-half cup of trisodium phosphate in a 2:1 ratio (TSP). Mix the solution with a long stir stick until all of the TSP has dissolved. Apply and scrape the TSP solution onto the brick with the stiff brush. 
Turpentine: Derived from tree resin, this organic solvent is often used by artists to thin and remove paint. It can be used to remove oil-based paint, acrylics, varnishes, tar and tree sap. It can be used as a thinner for oil-based paint, but shouldn’t be used to thin water-based paint, latex paint, lacquer or shellac.
Does acetone destroy paint?
Chemical Solutions – The majority of us dislike chemicals and their odors. In recent years, however, one of the most effective methods for removing paint from metal surfaces has been the use of chemicals. Ammonia and acetone are the two most common solvents used worldwide to remove paint off metal surfaces.
