Use

Pre-treatment

For best result, the temperature in the work area should be between 10–25 °C. Store the dry mortar and other materials so that they will remain over 10 °C before use. At temperatures lower than 5 °C, the strength development will cease. If the product is used in temperatures below 5 °C, then winter measures should be implemented. The substrate should be clean and free from dust, cement skin, grease or other impurities that can prevent adhesion. Smooth or glossy surfaces may need to be primed for maximum adhesion. Dry and highly absorbent substrates may be pre-watered.

Mixing

remove_circle

The dry powder is mixed with approx. 1.5–2.0 litres of water (15-20%) per 10 kg bag. The mixing is done with a drill and a whisk for approx. 3–4 minutes. The filler is mixed into a homogeneous mass.

Application

remove_circle

The filler is applied with a trowel or a putty knife. Work the filler thoroughly into the surfaces to be repaired. The surface can then be filled or brushed to create the desired structure. The repair can be edge cut with a trowel or a knife after approx. 1 hour. Filler which has begun to cure may not be mixed with more water and must be discarded.

Post-treatment and curing
add_circle
remove_circle

Protect newly-cast surfaces from direct sunshine, rain and high wind. The strength will increase with post-watering of the cured material. Post-watering should always be done for at least three days in dry and warm weather, as well as in the case of strong winds. Use a water hose with a fine spray nozzle. Then cover the post-watered surface with plastic.
