Product Features
Special leveling mortar for clean, e.g. sand-blasted concrete, protecting the underlying concrete against carbonation and moisture by making the surface more impermeable and forming a smooth surface for the actual coating. Also suitable for finishing untreated exposed-aggregate surfaces.
Recommended Uses
Residential, commercial, industrial and storage buildings and others.
Approx. 4 kg/m² (= approx. 2 mm coat)
Thinner
Waterborne
Application Method
spraying, trowel
The temperature of the air, filler mortar and substrate must be at least +5 °C. Do not apply the mortar in hot weather or when the site is exposed to direct sunlight.
Surface preparation
Remove the existing coating or paint by sand-blasting. Remove any loose or damaged concrete, expose the corroded reinforcement bars by chipping and clean them of rust to at least grade St2. Carefully remove all grinding and chipping waste. Treat the cleaned steel with anti-corrosion paint and make any required repairs with Finnseco repair mortars according to the work instructions.
Painting
First coat:
Wet the surface thoroughly 1 to 2 hours before starting to apply the coating. You can start applying the mortar when the surface is no longer glossy. Spraying Spray the mortar on mechanically and level it with a steel or cellular rubber float. You can finish the surface lightly with a sponge float in 10–40 minutes from application, according to the conditions. On exposed-aggregate surfaces, brush the mortar into a compact coat 2–3 mm thick on the substrate immediately after spraying. Finish the following day by spraying a thin coat of mortar onto the surface. Application with a trowel Apply a 2–3 mm thick coat of mortar manually with a steel or cellular rubber float. You can finish the surface lightly with a sponge float in 10–40 minutes from application, according to the conditions. NOTE! Only mix as much mortar as you can use in 30 minutes.
