What is the benefit of additives used in the sealer mix?
Since Hills Blacktop, Inc. uses a sand load of 5-7 pounds per gallon in the sealer mix, it is necessary to use Top Tuff. It helps keep the sand in suspension while in the mixing tank. It also improves surface toughness, anchors the sand in for extended wear, reduces power steering marks, provides a blacker dried film, and enhances the resistance to oils, fuels, and grease. You should know that by using additives, it will thicken the sealer, and many contractors are known to use additives in order to cut the sealer with more water, since sealer is a water base product. This actually gives you an inferior product, as there is too low of a solid content in the mix. This will not allow the sealer to wear as well as it should, therefore, shortening the lifetime.
