• Water and weather resistant
• Requires only the addition of water

Marlon Tamping Concrete EPF is used for the more demanding tamping applications, which are typically elements, machine foundations, banisters, guard-rails, noise barriers, concrete structures on bridges, beams, slabs and pillars. Suitable for repairs and renovations of balconies, façades, stairs, filling cracks etc. with a concrete surface.

The surface must be well-suited and washed clean of any oil, grease, cement slurry and other loose particles. The cleaned concrete surface must be watered, to produce a uniform, dull and slightly absorbent surface. Reinforcement iron must be cleaned of rust and chlorides. Metal surfaces must be cleaned of grease, rust etc. To ensure the best possible adhesion to the surface, we recommend priming the surface with Marlon Adhesion Primer CP (see separate data sheet).

Marlon Tamping Concrete EPF is mixed with cold water and mixed in a suitable agitator mixer. Mix well for at least 5 min., until the mixture has a lump-free, plastic consistency. Smaller amounts can be mixed in a tub/bucket using a drill with a two-bladed propeller agitator on low speed. When mixing with a drill, first pour the water into the bucket, and then add the powder while mixing.

Apply and compress the mixed tamping concrete thoroughly. Application may be done by hand (remember gloves) or using suitable masonry tools. If you will be using adhesion primer (Marlon Adhesion Primer CP), make sure to work "wet on wet". The recommended thickness is from 10 to 150 mm. The subsequent finish can be done with plastering or steel trowel plastering tools. The working time is approx. 30 min. at +20°C. Lower temperatures prolong, and higher temperatures shorten, the opening and hardening times.
