How do you remove paint from concrete? If you want to remove paint from concrete, use a specialist paint remover. In our product range, you will find a product called BETOFF-REMPAI. This is an innovative agent that you soak in and then remove the paint after waiting, usually 15 minutes (the waiting time depends on the age of the paint and its thickness).
Removing paint from a concrete surface can happen for a variety of reasons.
Do you have a concrete surface needing work, such as a patio or garage floor? Or have you inadvertently knocked over a paint can on a concrete floor? Perhaps painted concrete just doesn’t appeal to you. The organic look of concrete may appeal to some homeowners.
Removing the old paint will ensure better adhesion and a more durable finish if you add a new coating such as paint or sealer. Particularly in high-traffic areas, peeling or chipping paint can be a tripping hazard. Removing the paint can increase safety.
Whatever your motivation, below you can find a thorough guide on how to effectively remove paint from concrete. Although removing paint from concrete can be a difficult operation, it is completely doable with the right methods and equipment.
We also discuss all the equipment and materials required to remove paint from concrete floors, including protective equipment, several types of brushes, and more. While some homeowners choose to hire professionals to remove the paint, many choose to do it themselves. If you’re still unsure, this guide to removing paint from concrete will provide you with enough knowledge about the procedure to make an informed choice!
How do you remove paint from concrete? Assessing the surface and the paint
Before proceeding with paint removal, it is essential to assess the type of paint and the condition of the concrete surface:
Determine the type of paint: Check whether the paint is oil-based or water-based. In general, water-based paints are easier to remove. Although oil-based paints are more traditional and durable, their application can be risky. Due to their ease of application, fast drying time, and low levels of volatile organic compounds (VOCs), water-based paints have gained popularity in recent decades.
Examine the surface of the concrete: Check the surface for any damage, such as spalling or cracks. Also, consider any unique sealers or coatings that may affect the removal procedure. Visually inspect the concrete surface for a glossy sheen, as this often indicates a sealer. Also, if water does not soak in but instead collects on the surface, this means that the surface is probably waterproofed.
It is worth carrying out a water test. Add a few drops of water to the surface. The concrete is likely sealed if the water does not absorb immediately and instead collects on the surface. The concrete may not be sealed or the sealer may have worn off if the water is absorbed quickly.
How do you remove paint from concrete? Setting up the space
Clean the area before starting work. Anything that has been on the concrete surface, such as plants or furniture, should be removed. The surface should then be swept or vacuumed to get rid of any loose dirt or debris.
In addition, all equipment and materials should be collected. There are standard tools for removing paint from concrete surfaces, including sandblasting, pressure washers, and chemical paint removers. A brush, scraper, knife, and goggles for eye protection are also required. Details will be discussed below.
Paint removal. Gentle cleaning techniques
BETOFF-REMPAI liquid: Apply the liquid to the paint you intend to remove. Use a brush with strong bristles to scrub the affected area. For minor soiling, this approach may be sufficient. After washing the concrete surface, you can use a paint scraper to remove the dissolved paint from the concrete. Alternatively, you can use a pressure washer after you have soaked the paint with BETOFF-REMPAI liquid.
Choosing the right product
Choose a paint remover designed specifically for concrete surfaces. We recommend using BETOFF-REMPAI liquid. The use of paint thinner or acetone is not recommended. Pay particular attention to the manufacturer’s instructions. The type of paint, the condition of the concrete, and individual preference are some of the variables that determine which chemical paint stripper is best for concrete. BETOFF-REMPAI removes paint without damaging the concrete.
How do you remove paint from concrete? How to use
Using a paintbrush or roller, apply BETOFF-REMPAI evenly to the painted area. Always wear protective equipment such as gloves, safety goggles, and a respirator when working with chemical paint strippers. In addition, to prevent the inhalation of fumes, work in an area with adequate ventilation. However, in the case of BETOFF-REMPAI liquid, precautions can be reduced as it is not corrosive, does not vaporize, does not suffocate during application, and does not scald the skin. What’s more, BETOFF-REMPAI is 100% biodegradable!
How do you remove paint from concrete? Time to dissolve paint on concrete
To remove the paint from the surface of the concrete, wait the suggested time. As we wrote above, it is usually 15 minutes, but a lot depends on the type of paint and its thickness. 15 minutes is the minimum; you may have to wait as long as 2 hours. Most chemical paint removers need between thirty minutes and two hours to completely remove paint from concrete surfaces. The manufacturer’s instructions will have specific recommendations for the product to be used; these must be followed carefully.
Once the paint has dissolved, rinse the concrete floor completely with water from a high-pressure garden hose. If you do not have access to pressurised water, you can also simply pour a large amount of water from a bucket or plastic bottle.
State-of-the-art techniques for removing paint from concrete with pressurized water
Paint can be successfully removed from larger external surfaces using a pressure washer. Pressure washers clean surfaces by applying water under high pressure. Concrete, terraces, siding, and other surfaces can benefit greatly from the removal of dirt, grime, and mold. Care must be taken to prevent damage to concrete surfaces. Although power washers and pressure washers are sometimes used similarly, power washing can damage concrete surfaces and not just remove paint, as it uses hot water and high pressure.
Grinding or sandblasting
For deep-rooted or old paint, sandblasting, blasting, or even grinding may be necessary. Use appropriate tools and wear protective equipment such as a respirator. Although sandblasting can remove paint quickly and effectively, if done incorrectly it can also damage the surface of the concrete. The concrete may be weakened or have an uneven, rough surface due to excessive pressure or the use of the wrong abrasive disc.
It is recommended that you speak to a qualified contractor who is experienced in sandblasting concrete. He or she can assess the specific requirements of a project and ensure that it is completed safely and successfully.
