A gallon of paint is heavier than a gallon of water. Mostly anything that mixes a solid into the water will be heavier than water. Most homes have a can of Spackle , which is a common liquid for patching drywall and it is almost twice as heavy as water. Of course,mercury is the heaviest liquid, but isn't common around the house anymore.
