Concrete adhesion (direct traction)
- Canister 1 kg
Approximately 0.02 kg of PROTECH FLEX PRIMER for every linear metre of joint to be treated.
Preliminary reinforcing impregnation of concrete surfaces, forming walls of flooring and roofing joints, prior to sealing it with polyurethane and epoxy-polyurethane sealants.
The application surfaces should be clean, free of incrustations, crumbling and non-adhering parts, dust etc.
Apply PROTECH FLEX PRIMER, using a brush with short bristles, on the walls of the joint to be sealed.
It is appropriate to provide for the insertion in the joint, whatever its nature and the specific foamed polyethylene kerb FILTENE FONDOGIUNTO, of the appropriate size for the joint to be sealed.
- Nitro thinner
- Cement-based or lime-based mortars
- Floor screed
- Metal surfaces
- Prefabricated concrete
Warning: it is a highly flammable material.
PROTECH BALCONY is a ready to use concentrated single-component solution, made out of silicone-based resins and organic polymers catalysed in solvent. The solution viscosity is lower than that of water, so as to penetrate any cracks liable for water
Integrated system to build industrial concrete floors with innovative and particular properties that differentiate it from those defined as being "traditional" due to drastic reduction or definitive elimination.
