Application Instruction
Surface Preparation
Ensure substrate is clean, free from contaminants. Roughen smooth surfaces mechanically. Grit blast reinforcing steel to SA 2 ½ profile before priming. Saw cut repair edges to 5mm, remove loose dust with dry, oil-free compressed air.
Priming
Apply galvanized/epoxy primer on reinforcing steel to prevent corrosion. Soak concrete surfaces & apply Estobond AR bonding agent, drying in about an hour. Applywhile Estobond AR is still tacky. Reapply if it dries over 8 hours at 20°C.
Mixing
Thoroughly mix before use. Use a slow drill (500 rpm) with a loop paddle for one bag or more. Aim for a standard consistency of 4.0 – 4.5 liters (16.0% - 18.0% w/p). Drier mixes aid in achieving higher build and reducing drying shrinkage risks.
Application
Apply using a wood float for good contact with the primed substrate, initially tamp/compact. Finish with wood float, steel trowel/sponge. Minimum layer thickness 10mm, building 40mm on vertical surfaces.
Curing
Estopatch MP is a cementitious repair mortar. It must be cured immediately after finishing in accordance with good concrete practice. Estocure P curing agent is recommended for this usage.
Cleaning
Estopatch MP should be removed from tools with clean water immediately after use. Cured material can only removed mechanically.
Precaution
Estopatch MP contains cement powder, which might be harmful to sensitive skin. In case of contacted with eyes, rinse with water immediately and seek medical advice.
