Layman asks for advice Is waterproof paint latex paint Where is it used Is it a bathroom and kitchen

Used in the kitchen or bathroom, not latex paint, is used for waterproofing, brush on the wall and ground after the waterproof test, (water accumulation for 3 days to see if there will be water leakage), waterproof paint to professional workers to brush, otherwise it is easy to be poisoned Oh do a good job of prevention to lay bricks
