Test Area
Always test Pre-Grind on a small area of the surface to be treated before overall application to determine suitability and results. Any non-reaction of the product indicates the presence of a sealer. Use a test location that is out of the way and not in the main area of the project.
Application
Apply by use of a high volume, low-pressure plastic sprayer. DO NOT USE metal sprayers. Do NOT atomize under high-pressure sprayers. After spraying, etching should take place immediately and will generate a foam or fizzing reaction with the concrete surface. Allow to remain on the concrete for about 10 to 15 minutes, and then add water using a plastic pump-up sprayer. Grind the first cut slightly wet, ensuring to turn off the dust control system. While grinding, a “mud” buildup will appear, and further grinding will quickly evaporate the water, and dusting will start. Once that stage is reached, turn on the dust control system, and continue grinding until the desired surface tension and finish is achieved. Continue to your next grinding step after the surface dries.
Spill Cleanup
Use soap and warm water promptly after the spill.
- Dilution & Coverage
ECOGUARD Pre-Grind may be diluted up to 1:3 parts water by volume with clean, potable water, depending on the surface condition. Use a more concentrated solution for heavily contaminated surfaces or to increase the etching process on hard concrete surfaces. Coverage is approximately 200 square feet per gallon and is dependent on concrete porosity. Coverage is typical for hard, mechanically troweled finished concrete.
- Limitations
If the surface reaction is not noticeable after applying the ECOGUARD Pre-Grind, the concrete may have a sealer or coating barrier that is preventing cleaner absorption.
In this case, to grind off the coating, we recommend the use of ECOGUARD BEAR CLAW or RIPPER tools for such removal. If heavy grease or soaked-in oil are present, pre-clean with Concrete Earth C-25 Citrus Solve degreaser before applying the ECOGUARD Pre-Grind.
