How to Choose the Right Paint Stripper
There are three categories at which paint strippers fall into namely, solvent, caustic, and biochemical
Caustic paint strippers
Caustic paint strippers, which are water-based, have a pH of 13 to 14. These contain lye as an active ingredient, which could be caustic potash (potassium hydroxide) or caustic soda (sodium hydroxide). The paint coat is loosened from the surface as the lye reacts with the oil component of the paint, turning it into soap. This type of stripper can cause lung irritation as well as skin burns.
Solvent strippers work on removing paint by either softening or dissolving the bond existing between the substrate and the paint film. This leads the paint coat to bubble up. Methylene chloride is a prevalent solvent used as a paint stripper but there are others used such as toluene, acetone, and ketone. Methylene chloride strippers are effective but the health hazards they pose are more extreme than caustic strippers are.
Biochemical strippers contain plant-derived solvents. These may contain terpenes, which are derived from pine or citrus; dimethylsulfoxide derived from wood pulp; lactic acid derived from corn sugar; soy oil; and citric acid. Some of these solvents have the capacity to induce skin irritation.
Aside from chemical paint strippers, there are other options for you to remove the current coat on the surface that you will be painting
Heat can also be used to remove paint. You can use a torch, heat gun, or a low-intensity infrared heating system. The use of open flame such as with a torch is hazardous, which means that this stripper should be avoided. Using a heat gun, on the other hand, also has its risks. The fumes that it produces is toxic and it can also cause a fire. The safest option among these is the low-intensity infrared heater since it produces low heat only. When planning to use heat as a means to strip paint, consider the EPA standards since certain paint formulas, when heated, give off toxic fumes.
Sanding is also another option for paint stripping. This can be done by hand or with a power sander. This technique quickly removes the old coating through grinding the surface and its finish. When working with wood, sanding can remove some of it such as its intricate carved designs. For some surfaces, especially those with engraved details, sanding can be done as a preliminary method of removing paint, which is completed using paint strippers.
Power washing is another option for removing paint, especially for the exteriors of a building. Spraying at high-pressure rates is effective in stripping paint from stone, wood, bricks, and concrete. However, for those who are not familiar with the strength of using a power washer, damage to the surface being stripped, most commonly wood, comes as a result.
Tips in Stripping Paint
- When using ready-made paint strippers, the first thing to do is read the label. The label will contain all the vital information such as the precautions you should take, preparation requirements such as shaking or stirring the stripper before use, length of time to let the stripper on the surface and many others.
- Whichever stripper you plan to use, it is important to safeguard your health by wearing protective wear. Cover your skin, wear respirators that will shield you from solvent fumes, wear safety glasses, and gloves.
- It is also important to keep the area well-ventilated so that the fumes from the process can escape. If you will be stripping removable accessories such as cabinet doors, it is best to take them outside from stripping. If the stripping cannot be brought outside, comply with the OSHA standard exposure limit. The air in the room must change from 7 up to 10 times every hour by using a fan that will carry the vapors outside the window.
- The application of strippers can be done with the use of a brush, spray bottle, roller, or sprayer. The appropriate applicator will depend on the stripper’s consistency and the size of the surface to be stripped.
- Leave enough time for the paint stripper to do its work. The length of time that you have to let is stay is indicated in the label. Once the time is up, start scraping the goo into a container. You can use a drywall knife to do this. Toothpicks can be used to remove those in areas that cannot be scraped by a knife.
- The last step is to neutralize and wash the surface after all the old paint coat is removed. Follow the manufacturer’s instructions for this procedure. After which, give sufficient time for the surface to air and heat dry prior to executing further surface preparations and painting a new coat.
