Application Procedure

Preparation of the substrate

• Remove all deteriorated and loose concrete to form a solid, rough and strong substrate. Any areas previously repaired and which are not perfectly bonded must also be removed.
• Remove all dust, rust, cement laitance, grease, oil and paint from the concrete and reinforcement rods by sandblasting or hydro-sandblasting.
• Saturate the substrate with water.
• Before carrying out repairs, wait until excess water has evaporated.

Preparing the product

Pour approximately 7.5 liters of clean water into a container and slowly add a 25 kg bag of Microtech while mixing. Carefully mix the blend for several minutes then remove any powder which has stuck to the sides and bottom of the container. Add more water to obtain the consistency required without exceeding the recommended amount, approximately 6-6.5 liters. Mix again for several minutes to form a well-blended, plastic consistency, lump-free mixture. Microtech remains workable for around 60 minutes at +10°C to +25°C.

Applying the product

Apply a layer of mortar from 3 to 40 m thick with a trowel or putty knife; no formwork is required. As soon as the mortar starts to set, tamp the surface with a sponge float. The waiting time required before carrying out this operation depends on surrounding weather conditions. To paint and protect the surface, apply a coat of an elastomeric product or an acrylic product.
