High-strength non-shrink grout material cause rough surface?

High-strength non-shrink grout material cause rough surface? 1. Rough surface template or adhesive slag cement and other sundry not clean, open mould grouting material surface is destroyed; 2. Template was not enough water moist or wet, component surface high-strength non-shrinkage grouting material moisture is sucked, grouting material excessive water loss occur pits; 3. Template flat-fell seam is lax, local slurry leakage; 4. Coating uneven template isolation agent, or local brush or leakage failure, grouting material surface and template binding pits; 5. High-strength non-shrink grout material vibrating untrue, bubbles not discharge, parked in the template form pitting surface phenomenon.
