Kalmatron-Adgeziv — anti-corrosion and bonding compound for rebar

Rebar protection and bonding primers

Kalmatron-Adgeziv is a dry mix based on Portland cement with adhesion and anti-corrosion admixtures that performs two tasks in repair. Cleaned rebar is coated with it using a soft brush in two passes, while on damp concrete it is applied with a stiff brush as a bonding primer, onto which high-strength cementitious repair mortars are placed. Bond to metal is at least 2.5 MPa, to concrete 1.5 MPa, contact zone frost resistance Fkz 50; packaging — 25 kg bags and 3 kg buckets.

Application methodanti-corrosion treatment of rebar before applying repair mortars and bonding primer before high-strength cementitious repair mortars; clean rebar and concrete of corrosion by sandblasting or with steel-bristle brushes (steel cleaning degree 2½), treat dense and smooth substrates and weak layers with sandblasting or water-jetting equipment, moisten the substrate without puddles; water 180–200 ml per 1 kg, mixing with a mixer for 2–5 min; do not add cement, aggregates or water; bonding layer — with a stiff brush on a damp substrate, place the repair mortar on the slightly set bonding coat, do not allow it to dry out (if it dries — a second layer)
Application temperature+5…+35 °C (substrate and environment during the work and for 12 h afterwards)
Curingbefore applying the repair mortar — hardening for about 2 h (+20 °C); before mechanical spraying — full cure, at least 12 h (+20 °C); protect from mechanical damage, rain, direct sun and draughts
