From 350 to 700 g for each square metre, based on the intervention carried out on the support (bush-hammering, shot peening, etc.), the porosity of the support itself and the incorporation or not of quartz sand in the particle size and quantity proportionate to the intervention to be implemented.

Use fields

Adhesion promoter for epoxy, polyurethane and polureic coatings, adhesion promoter for porous and deteriorated substrates, consolidating agent for cement and concrete.

Preparation of supports

The surface of the support needs to be dry, well cleaned, free of any debris and without crumbly or detached parts. Any support must have a humidity content not exceeding 5%.
Where necessary, depending on the support, we recommend the following interventions:
Bush hammering
Shot peening
Pressure washing
Any contamination (water, dirt, dust, etc.) must be carefully removed before recoating.

Use method

Carefully mix component A to allow the correct homogenization of the fillers present; then combine it with component B in a suitable and large container. Then mix the compound with a mechanical stirrer at low speed until a homogeneous mixture is obtained.
When the support is ready, apply SYNTECH POLIUREA PRIMER - EPOXY using rollers, brushes or spatulas trying to obtain a dry film.
