Paint stripping chemicals will dissolve skin the same way it dissolves paint, always wear protective gloves and eyewear, and do not come in direct contact with the solution.
Caustic alkali solution is a chemical paint removal gel that can be applied thickly by brush and allowed to sit on the surface for 2-24 hours, depending on the condition of the paint to be removed. Follow the chemical manufacturer’s instructions.
In order to keep the gel actively caustic, it must remain wet. An occasional fine misting of water will help. If the paint is stubborn or very thick, it will be necessary to leave the solution overnight. In this case, cover it with plastic to retain the moisture and maximise the caustic effect.
After the paint has been dissolved in the solution, it will be soft enough to easily strip off using a scraper.
