Directions for use
Before you begin
- Perform the splash test. Sprinkle water on the surface to be treated. If water absorbs and darkens color of the surface, the surface is considered ready to be treated. If water beads up or otherwise sits on top of the surface, the surface does not need protection at this time.
- We strongly recommend a trial patch before you start. Formula may impart a slightly darker color on lighter fabrics.
- Apply only to colorfast materials. Test for colorfastness in an inconspicuous place before treating the entire surface. Spray surface until wet. Wipe with white absorbent cloth. If color comes off, do not treat the surface.
- Before applying to furniture, check the furniture manufacturer’s care and warranty information.
- Protect surrounding areas from overspray.
- Use in a well-ventilated area, away from heat and flame. Do not use while smoking.
Surface preparation
- Surface must be clean and thoroughly dry.
Application
- Hold can in upright position 6 to 8 inches from surface.
- Spray liberally and evenly over entire surface. Do not saturate.
- If applying to upholstery, avoid heavy saturation into cushioning.
- Two coats are recommended. Allow a drying time of 4 hours between coats.
- To maintain waterproofing, reapply after every cleaning. Reapply annually.
Drying
