Content: The salt crystals absorb moisture very quickly and turn the paint into a solid, rubbery substance. The solid cannot "re-wet," so the paint will not return to its liquid form even if it comes into contact with liquid at the landfill. Sodium polyacrylate needs water to produce this chemical reaction, so paint hardener cannot be used with oil-based paints. Oil-based paints must be taken to a hazardous waste disposal or recycling center. Safety Precautionsu001a
Paint hardener may cause slight to moderate eye irritation if particles come in contact with your eyes. The dust from the main ingredient, sodium polyacrylate, may also cause lung inflammation if inhaled. Most people will not be affected by the dust, but people with asthma or other respiratory conditions may want to take precautions by wearing a dust mask while pouring the paint hardener into paint cans. Those with sensitive eyes may want to wear protective eyewear while working with paint hardener. Make sure that your bare skin is safe and does not come in prolonged contact with the paint hardener, since it can cause irritation and redness. Advertisement
