Best Practices for Dow Z-6689 Water Repellant

*See Terms of Use Below
1. Surface Preparation
  
  Surfaces should be free of standing water, surface dirt, dust, oils and other contaminants.
2. Application
  
  Methods of application include airless sprayer, roller and brush. When a brush or roller is used, repeated applications should be made until the surface remains moist for a few minutes. If an airless sprayer is used, application should continue until the substrate is thoroughly saturated. On vertical applications, material should be applied from the bottom up and achieve a 6- to 8-inch rundown. Sprayers should be fitted with solvent resistant hoses and gaskets. To ensure compatibility and the desired water repellent result, a test application is necessary on each surface to be treated. Surfaces should be free of standing water, surface dirt, dust, oils and other contaminants. Formulated Dow Corning Z-6689 Water Repellent may be applied to damp or wet surfaces, although dry surfaces are preferred to achieve maximum penetration into the substrate. As with most repellents, plants or shrubs should be protected from exposure to the treatment. Windows and any other material that should not be treated must be protected or cleaning with solvents may be necessary to remove the treatment. Likewise, if applied as spray, control overspray and drift to prevent contamination of nearby substrates, especially windows, vehicles, etc.
