This will ensure that no residue is left behind. The paint remover will simply have an easier time activating and saturating the surface as a result of this.Īfter the area has been sanded and cleaned, start the removal procedure by applying a heavy layer of the stripper with a paintbrush. To begin, sand the surface very lightly to agitate any topcoat that may be there. We used it to remove decades’ worth of paint layers from wooden siding, as well as to assist in the removal of paint layers that were already bubbling and flaking. Products in this category cover the gamut from “natural and safe” to alternative, with varying levels of volatile organic compounds (VOCs). Paint remover liquids and gels are, in general, an efficient method for removing thick coats of paint from wood surfaces. In the workplace, the Health and Safety Executive allows for very low levels of sodium hydroxide exposure. Paint strippers that contain caustic should never be used on hardwoods because this will cause the wood to become permanently discolored. To give one more example, caustic alkalis are destructive to the cellulose fibers found in wood, which results in irreparable damage. When handling caustic paint remover, extreme caution is required because, for instance, the substance can cause burns to the skin.īecause caustic-based paint strippers are known to draw moisture, dampness can also be a problem, as was mentioned above. The sodium hydroxide is the one that reacts with the oily components of the paint and begins the process of breaking down the paint. They have a pH that is extremely high, and the active element that they typically contain is sodium hydroxide. Paint removers that contain caustic compounds have a slightly distinct mode of operation since these components work toward decomposing the chemicals that are contained in the paint. Despite this, one should exercise extreme caution while working with paint strippers of any kind, including those that are water-based. These new compounds pose an additional risk. The extremely flammable nature of methylene chloride necessitated the substitution of alternative active components in several solvent-based paint strippers currently on the market. When you find an old can of paint remover, you should be cautious about what you do with it. Paint strippers sold to consumers in the European Union were not allowed to contain this chemical compound after the European Union decided in 2010 that the chemical posed too many potential health concerns.Īs of recently, the use of goods containing methylene chloride has been limited to only workshops hence, documentation of this restriction will be required prior to the purchase of any paint strippers containing methylene chloride. Methylene chloride was a component that was traditionally found in paint strippers that were based on solvents. The majority of them will also have trace levels of solvent present in their chemical composition, albeit nothing close to the goods that are based entirely on solvents. The components perform their function by increasing the thickness of the paint and reducing the paint’s ability to adhere to the surface.īecause water serves as the “solvent” in these goods, the category that includes paint strippers that are based on solvents also includes water-based technologies. ![]() ![]() Paint removers that are based on solvents function by severing the bond that holds the surface and the paint together.
