APPLICATION <br />Read “Preparation” and the Safety Data Sheet <br />before use. <br />ALWAYS TEST a small area of each surface to <br />confirm suitability, coverage rates and desired <br />results before starting overall application. Include <br />in the test area any previous repairs and patches, <br />including aesthetic cementitious finishes. <br />Different surface compositions may result in <br />absorption and/or appearance differences. Test <br />with the same equipment, recommended surface <br />preparation and application procedures planned <br />for general application. <br />Dilution & Mixing <br />Apply as packaged. Do not dilute or alter. <br />Vertical Application Instructions <br />For best results, apply “wet-on-wet” to a visibly dry <br />and absorbent surface. <br />Sprayer: Saturate from the bottom up, creating <br />a 4–8 inch (15–20 cm) rundown below the spray <br />contact point. Let the first application penetrate for <br />5–10 minutes. Re-saturate. Less will be needed for <br />the second application. <br />Brush or Roller <br />Recommended for small scale application or <br />when spray application is not appropriate. <br />Contact PROSOCO for more information. Saturate <br />uniformly. Let penetrate for 5–10 minutes. Brush <br />out heavy runs and drips that don’t penetrate. <br />Horizontal Application Instructions <br />Saturate in a single application. Use enough to keep <br />the surface wet for 2–3 minutes before penetration. <br />Broom out puddles until they soak in. <br />Dense Surface Application Instructions <br />Apply a single coat. Use enough to completely wet <br />the surface without creating drips, puddles or <br />rundown. Do not over apply. Test for application rate. <br />Drying Time <br />Treated surfaces dry to touch in 1 hour. Protect <br />surfaces from rainfall for 6 hours following <br />treatment. Protect from foot and vehicle traffic until <br />visibly dry. Siloxane PD gains its water-repellency <br />properties in 72 hours. <br />Cleanup <br />Clean tools, equipment, and over spray with soap <br />and warm water. <br />Paint Adhesion <br />Always test to make sure paint sticks to treated <br />surfaces. Improve adhesion before painting by <br />pressure water-rinsing the treated surface, then <br />letting it dry. <br />Some cementitious coatings, plaster, stucco, etc. may <br />not adhere well to treated surfaces. Install them first <br />and let them thoroughly cure before application. <br />Always test to verify compatibility between Siloxane <br />PD and other proposed surface treatments. <br />WARRANTY <br />The information and recommendations made are <br />based on our own research and the research of <br />others, and are believed to be accurate.
