Three Cheap Ways to Remove Paint from Your Concrete Wall Three Cheap Ways to Remove Paint from Your Concrete Wall
You may think that once you paint a concrete wall, the paint can never be removed again. Fortunately, this is not the case, since there are several cheap ways of removing paint from concrete walls. This allows room for renovation, since you may decide to change the color of a particular room, or to simply remove the paint and leave the room as it is. A number of cheap techniques can be resorted to if you want to leave your concrete walls looking as though they never had a trace of paint on them.
1. Scrape it Off
The most common way to remove paint is by scraping it off, and the same is true for concrete walls. Before starting, lay a cloth on the floor beneath the area you will be working on, so that the flaking paint can be easily removed later on. Then wipe the wall with a soft cloth to remove any loose paint or dirt before starting. When ready, place the blade of your scraper against the wall and start to push it under any cracked paint. The scraper’s blade will cut through any loose chips, making them fall from the wall. Keep running the blade over the cracked area in all directions.
Once you are happy with the result, fill a bucket with warm water and wall-washing compound. Using a soft cloth, wipe the wall until all the dirt, grease, dust and loose paint chips are removed. Finally, dry the wall with a separate soft cloth and your concrete wall should look as good as new
2. Paint Stripping Agents
Certain chemicals are perfectly suited for removing paint. There are two main categories of these sort of chemicals – solvent-based strippers (SBS) and caustic-based strippers (CBS). The proper use of chemicals is the easiest and quickest way to remove paint, since the stripper first softens the painted surface, which can then be easily scraped off or washed away with water.
Liquid strippers dry very fast and are thus best suited for walls with one or two paint layers only, as well as for irregular surfaces. On the other hand, thick, paste-like strippers can be used for walls with multiple layers of paint. There are also paint-removal agents which come in sprays, and which are therefore meant for easy application. Similarly, aerosols are formulated for convenience and speed. Like sprays, they produce a foamy layer over the wall which serves to remove the paint.
3. Heat Application
Heat is also a widely used method for paint removal. As in the first method, make sure you cover the floor before starting the process. In this case, wipe the wall with clean water to ensure a chemically free surface to work on. Then prepare your heat gun, giving it time to heat up in a safe place. Once it heats up, point it at the wall, keeping it around 5 inches away from the surface. Heat the wall’s surface until the paint begins to bubble. Naturally, you will need to scrape away the paint when it starts bubbling. The cloth on the floor will ensure an easy cleanup.
A concrete wall’s paint is not forever – these three cheap methods will help you remove the paint whenever you want.
