PÅFØRING
Påførings-betingelser
The surface to be treated has to be dry, the temperature of the air at least +5 °C, and the relative humidity of the air below 80 %. Do not paint under strong sunlight.
Forberedelse
New concrete surfaces:
Remove dirt, loose material and salts from unpainted concrete surfaces. Pre-cast concrete surfaces can be painted after the first heating season. Surfaces cast using formwork must be mechanically worked (e.g. sand-blasted) to create sufficient texture and remove the glass-like, glossy hydrated cement. Similarly, the cement paste on cast surfaces must be removed by sand-blasting, steel brushing or high-pressure washing with the addition of sand. Concrete surfaces which are very porous are recommended to be treated with Finnseco Polytop finishing mortar. Treat new plaster surfaces after a curing time of 1-2 months.

Previously painted surfaces:
Remove flaking, poorly attached or powdery paint coats from previously painted surfaces. Choose the method of removal according to solidity of the substrate and type of paint to be removed (e.g. steel-brushing, high-pressure washing or water-sand blasting). Remove also poorly attached, fragile plaster and concrete surfaces. Open possible cracks in concrete constructions by pick- dressing, or with edge grinder and bobbing. Clean rust from the reinforcement bars, and continue the treatment using a suitable Finnseco repair mortar. Sand-blasted, very porous concrete surfaces are recommended to be finished with Finnseco Polytop finishing mortar.

Applicable national health and safety precautions must be followed in the pre-treatment and coating of substrates containing asbestos.
Patching
Patch opened cracks, holes and hollows to the same level as the surrounding concrete surface with a suitable Finnseco repair mortar, and plaster surfaces with lime cement mortar. Cure the patches with care and allow them to harden before painting.
Påføring
New concrete surfaces and hard lime-cement plaster surfaces:
Apply two coats of FinnGard 500. Drying time of 12 hours should be allowed between coats. If necessary, FinnGard 500 can be thinned with max 5 % of water.
Old unpainted concrete surfaces or surfaces where the old paint has been removed:
a) Prime concrete surfaces with a mixture of Alfagel 400 and FinnGard 500 (1 volume part Alfagel 400 and 4 volume parts FinnGard 500, which is approximately 3.3 kg of Alfagel 400 and 25 kg of FinnGard 500). Apply FinnGard 500 earliest 12 hours after priming.
b) Prime the surface with Kivisil primer or Alfagel 400 according to the instructions on the data sheet. Apply two coats of FinnGard 500 after the primer has been absorbed into the substrate (surface does not appear glossy). Drying time of 12 should be allowed between the coats. FinnGard 500 can be thinned with water max. 5%.

Overcoated surfaces can be also treated without priming by applying two coats of FinnGard 500. However the use of silicone primer improves the protective capability of the coating.

Rengøring af værktøj
Clean tools with water.
Vedligeholdelsesvejledning
Avoid cleaning for a month. After that, the surface can be cleansed carefully with a high pressure cleaner without detergent. The cleaning can leave permanent mark on the surface so, carefully wash according to joints. Remove loose dirt lightly with a brush without rubbing.
Apply Tikkurila Mould Removal to remove mould or algae. Rinse well.
Note! After using Tikkurila Mould Removal always recoat the surface.
Vedligeholdelsesbehandling
Clean paint splashes immediately from windows, or protect the windows before priming and coating.

Careful pressure-washing without cleaning detergents is usually enough. For biological growth, such as mould or algae, use hypochlorite solution (e.g. Homeenpoisto 1), and rinse well.

FinnGard 500, FinnGard 150 or Kivisil Facade Paint. Check the condition of the structures and do necessary repair work before maintenance painting.
The paint can be thinned up to 5-10% with water for priming, if necessary. Finish with unthinned paint. Follow the recommended coverage values to ensure maximum protective effect. Adjust overlapping to structural details, windows, joints of elements etc.

Surfaces painted with FinnGard 150 can be re-painted with FinnGard 150
