Recommended Usage Instructions

1. Prepare the Grout
   • Mix MACt Grout: Combine the grout powder with water and desired pigment.
   • Achieve Toothpaste-Like Consistency: Ensure thorough blending for optimal texture and minimal lumps.
2. Dampen the Substrate
   • Pre-Wet the Surface: Lightly moisten the concrete or GFRC to help the grout retain moisture and reduce cracking.
3. Apply the Grout
   • Wear Gloves: Press grout firmly into voids, microcracks, and corners, using your hands for maximum control.
   • Address Large & Small Imperfections: Ensure even coverage without air pockets.
4. Remove Excess Material
   • Clean While Workable: Wipe away surplus grout before it fully sets, preventing difficult sanding later.
5. Curing & Sanding
   • Allow Several Hours: Let the grout cure (longer in cooler conditions).
   • Sand the Surface: Use 180–240 grit sandpaper for an even finish; handle corners manually to preserve edges.
6. Repeat if Needed
   • Check for Imperfections: Reapply and sand again if any holes remain after the initial curing period.
7. Final Finishing
   • Sand Entire Surface: Achieve a smooth, consistent texture with a final pass of 180–240 grit paper.
   • Clean & Seal: Remove dust with a damp cloth, then apply a suitable sealer for ongoing protection.

Helpful Tips

• Colour Adjustment: If the cured grout appears lighter, add about 1.1–1.2 times the usual pigment to achieve desired depth.
• Whole-Surface Grouting: Grout the entire area to avoid patchiness or discolouration from spot repairs.
• Sealing Pinholes: MACt sealers won’t fill pinholes, so ensure they’re thoroughly grouted first.
• Prompt Clean-Up: Remove excess grout quickly to prevent excessive sanding work later on.
