SuperTectum
PU Primer
Universal, quick-hardening polyurethane-substrated primer with low viscosity
One-component, quick-hardening polyurethane primer, ideal for any substrate. It can be used on both porous and non-porous surfaces.

SuperTectum PU Primer is very similar for viscosity and ability to damp to SuperTectum Macro Primer, but the first one has much more increased curing rate, being used more successfully in cold climates (in autumn-spring period) and during the rain, it is not very predictable. This is the preferred option in cases of extreme porosity of the concrete surfaces.

The material has low viscosity and excellent impregnation properties, ideal for wet or dry concrete.
Application area

• Primer for polyurethane coatings
• Monolithic or precast concrete
• Metal structures
Features and benefits
One component
Fast drying
Low viscosity
Easy application
Excellent wetting, impregnation and short time for subsequent coating
Application procedure
1
Before applying, clean thoroughly the surface from dust, dirt, rust, oil products, cement mortar, plaster layer, paint and other materials that prevent adhesion. Bulk particles, loose and easily peeling layers and other foreign materials should also be removed.
2
Apply with a brush or a roller. Drying time from 2 to 4 hours, depending on air temperature. After solidification, a subsequent coating SUPERTECUM can be applied.
3
The total flow rate is 100-500 ml/m2, depending on the porosity of the surface.
