Adhesion Primer CP

Adhesion primer for reinforcement and concrete repairs

Product description

Marlon Adhesion Primer CP is a cement-based 1-component pre-mixed polymer modified primer mortar that requires only the addition of water. Used in combination with Marlon cement-based repair products.


•    1-component
•    Corrosion protection of embedded steel
•    Easy application with brush or sprayer
•    Excellent adhesion to steel and concrete
•    Requires only the addition of water


Marlon Adhesion Primer CP is a primer used to improve adhesion in connection with concrete repairs and for anti-carbonation and corrosion-inhibiting reinforced steel and structural steel.
To achieve the best results, it is important to use skilled labour with knowledge of concrete technology and renovation.


The surface must be well-suited and washed clean of any oil, grease, cement slurry and other loose particles through chipping, sandblasting etc. Damaged concrete must be chipped away down to healthy, adhesive concrete. Reinforced iron and other cast steel must be cleaned with a wire brush to remove rust, chlorides and other impurities. The surface must be slightly absorbent and should be dampened as needed. Marlon recommends having the surface approved by a consultant or inspector before starting repair work.


Add clean mixing water to Marlon Adhesion Primer CP in a bucket/mixing tub and mix thoroughly with a drill and mixing attachment. Mix until you achieve a fluid, workable paint consistency. The mixing time is approx. 5 min.


Thoroughly brush the mixed adhesion primer into the cleaned and exposed surface. The surface should be slightly absorbent. Apply Marlon Adhesion Primer CP in a 2-3 mm layer using a hard brush. It is important to brush the mortar all the way out to the edges and especially on the back of any reinforced steel. All embedded steel and concrete surfaces must be fully coated. Preparation time is approx. 30 min. at +20°C. Higher temperatures will shorten, and lower temperatures will lengthen the processing times. Subsequent repair must be done before the adhesion primer begins to harden “wet on wet”.


Do not use Marlon Adhesion Primer CP at temperatures below +5°C. Coated surfaces do not tolerate frost during the cementation period.


Clean tools with water immediately after use. Hardened Adhesion Primer CP can only be removed mechanically.


Marlon Adhesion Primer CP is subject to internal testing according to Marlon’s quality assurance system. Subsequent measuring and mixing at the application site is not included in quality control.
