Latex paint low biocide & VOC levels another top choice. Latex paint is safer for the environment than oil-based paint, but it needs to be used with great care due to the strong terpenes. Acceptable paints, although they contain biocides include latex, acrylic, and recycled latex paints, assuming they don’t contain mercury or lead. Avoid oil- and solvent based paint products. No matter which interior paint you use, it is best to keep room well ventilated. Never use old paint that may contain lead. Lead-based paints are extremely toxic, especially to pets or children who could eat dry paint chips. If you suspect that your home contains lead-based paint, call a certified professional to inspect and if needed, remove the paint.
