When to choose this product
For pinholes, small voids and surface imperfections exposed during concrete grinding. Mixes with grinding dust to fill defects and create a more uniform surface for polishing.
Product advantages
- Automatically fills gaps, voids and pop outs during grinding operations.
- Quickly cures to concrete hardness.
- Treated surfaces polish faster and easier.
More advantages
- Applied with a pump sprayer; can be diluted as specified for demanding site conditions. Filled pores help later colorants and protective treatments spread more evenly and reduce dirt traps.
Fills pinholes, small voids and microcracks during grinding. The TDS gives no maximum crack width; assess larger or moving cracks separately.

Preparation and working conditions
Surface and air temperature10 ≤ T < 32 °C
Work at 10–32°C, during the later metal-bond or first resin-bond grinding stage, before densifying and polishing. Stir well. Use as supplied; up to 50% water may be added if diamonds gum up or conditions are hot and dry.
Equipment
Use a low-pressure sprayer. Distribute evenly without puddles; avoid forming a fine mist.
Practical advice
Test a representative area with the equipment and preparation planned for the job. Let it dry before assessing the result and coverage.
Allow 2–12 hours to dry before continuing the grinding process. Reconnect dust extraction for subsequent dry work. Clean tools with soap and water before the product dries.
