Description

Polymer-modified cement mortar that slows down the penetration of moisture and carbon dioxide into the underlying concrete. Finnseco Polytop, gray: SILKO-approved (3.231).


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.


Coverage

Approx. 4 kg/m² (= approx. 2 mm coat) Grade 0–0.6 mm.


Application Method

spraying, trowel


Application Conditions

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 Finnseco-KOR anti-corrosion paint and make any required repairs with Finnseco repair mortars according to the work instructions. MIXING THE MORTAR Add Finnseco Polytop filler mortar into clean water (4.5–5.5 l of water to 25 kg of mortar) and mix mechanically to an even consistency. Let the mix stand for approx. 5 minutes before mixing again and starting work. Tinted Finnseco Polytop filler mortar is prepared by mixing a 25-kilogram sack of Valkoinen Finnseco Polytop sack mechanically with 4–4.5 l of clean water to an even consistency. Add a one-liter jar of Finnseco Sävytyspasta into the mix and stir. Rinse any leftover paste from the jar with approx. half a liter of water. Pour the rinsing water into the mix and stir. Let the mix stand for approx. 5 minutes before mixing again and starting work. You should use the same amounts of water and consistent mixing times across batches to maintain a uniform result.


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. When treating a substrate containing asbestos, follow the Government Decision on Asbestos Work (1380/1994) and the related Decrees 318/2006 and 863/2010.
