Waterproofing coatings have been around for more than 50 years and offer a value solution for damp or leaking basements and other masonry surfaces. The first ready-mix waterproofers were oil-based formulas. Oil-based waterproofers have good resistance to water pressure. However, the oil-based formulations produce an objectionable odour and promote film yellowing, which are major obstacles to consumer acceptance. Ready-to-use latex waterproofers were introduced in the US in the early '80s and offered a viable alternative to oil-based formulations. Water-based products have far less odour than their oil-based counterparts, making them less objectionable for the use by consumers. Recently, Zinsser in Somerset, New Jersey (USA), has developed Watertite with an oil-based formula that uses state-of-the-art waterproofing resins. Because it was developed as an oil-based product, instead of water-based product, the Zinsser chemists found they could incorporate Portland cement into the formulation without sacrificing shelf stability and could eliminate sand completely without sacrificing efficacy. Tests have demonstated that the new waterproofer stopped 10 psi of water pressure - twice the water pressure of other oil-based or water-based waterproofers on the market. Watertite proved ideal for application to wet walls, giving consumers the ability to take care of water problems immediately instead of waiting until walls are dry, as is the case with other waterproofing products. The new product gives a nearly odourless and a smooth finish and it prevents the growth of mould and mildew on the paint film for five years.
