The Dry Guy Waterproofing proprietary formula has been developed with the utmost care to provide an effective waterproof treatment without utilizing traditional chemicals which can be harmful not only to the environment, but which also could contribute to personal health and safety issues for you and your family. Dry Guy works in close cooperation with leading chemicals manufacturers, keeping in mind our key selection criteria which includes environmental sustainability, biodegradability and the use of renewable raw materials. Water is the sole dilutant in our waterproofing products, thus avoiding the use of harmful solvents or alcohols which can lead to not only environmental damage, but also personal exposure complications to humans and animals as well as potential fire and explosion hazards. There are no PFOA, PFOS, nonylphenol-ethoxylates, glycol ethers or hazardous air pollutant substances (HAPS) used in the formulation. The ingredients which we incorporate meets the goals of the US EPA Stewardship Program.


The Dry Guy Waterproofing proprietary formula is the most effective technique for imparting hydrophobicity (water-repellency) to a porous surface (fabric) to alter the surface (fabric) tension properties. If the solid fabric surface has been impregnated with a material which interacts with the surface matrix so as to lower its surface energy, when liquid water comes in contact with such a fabric surface, it has a tendency to pull itself into water droplets (since the water molecules are more attracted to themselves than to the molecules which make up the treated surface). Once these water droplets form, they tend to simply run off the treated fabric surface rather than wet into the surface. One significant advantage of this proprietary formula is that water vapour can easily migrate through the pore structure of the treated fabric surface, essentially unimpeded.
