Description

Water-borne, silicone-based primer (concentrate).


Product Features

For priming porous, water-absorbing unpainted surfaces or previously painted aggregate surfaces before painting with Finngard Clean facade paint or other paints suitable for organic aggregate surfaces, such as Yki.


Recommended Uses

Residential, commercial, industrial, storage and other buildings.


Coverage

Mixture coverage: 1–2 m²/l on rendered surfaces, 2–4 m²/l on concrete. Amount of Finngard Silikonipohjuste (undiluted) needed: 0.05–0.1 l/m² for rendered surfaces, 0.025–0.05 l/m² for concrete. The coverage is affected by the roughness and porosity of the substrate and the absorption qualities of any previous treatments applied to the surface to be primed.


Thinner

Waterborne


Storage

Must be protected from frost. Must be kept in tightly closed containers. The storage temperature must be below +30°C. The water-mixed working solution keeps for 24 hours.


Application Conditions

The surface to be treated must be clean, the ambient temperature at least +5 °C and the relative humidity of air below 80%. Do not apply the product to a wet or non-absorbent surface.


Surface preparation

Unpainted surfaces: Clean the unpainted surfaces of any dirt, dust and salt. If the formation of salt is very strong and continuous, the surfaces must not be treated before the cause of salt formation has been eliminated. Concrete element surfaces should not be primed earlier than after one heating period. Concrete surfaces that have been cast with formwork must be treated mechanically (e.g. sand-blasted) to create an appropriate surface profile. You can remove any glassy and glossy cement stone from the surface using sand-blasting, a mechanical wire brush or pressure cleaning with added sand. New rendered surfaces should be allowed to dry for one or two months before being primed. Previously painted surface: Remove any flaking, poorly adhering or powdery paint coats from previously painted surfaces. Choose the removal method according to the strength of the substrate and type of paint to be removed (e.g. wire brush, pressure washing with hot water or wet sand-blasting). Also remove any poorly adhered, fragile areas of plaster or concrete. If the substrate forms salts, the surfaces must not be treated before the cause of salt formation has been eliminated. In concrete structures, open any cracks over the reinforcement steel bars by chiseling or with an edge grinder, etc. Clean the bars of rust and continue treatment with Finnseco repair mortars.


Painting

First coat:

The surface of the primed area must always be treated.


Cleaning of tools

Wash tools with water and detergent (eg Pensselipesu)


Improves adhesion

The primer for mineral exterior surfaces enables improved coverage of the topcoat. In order to improve the adhesion of the paint to the surface, use Finngard Silikonipohjuste as a bonding layer for priming porous, water-absorbing masonry surfaces before painting.

Improves water repellency

Primer treatment improves the water repellency properties of the surface. Priming new or previously painted mineral substrates provides a surface that protects the facade from water.

Perfect result with Finngard Clean top coat

Finngard Silikonipohjuste provides the ideal base for painting porous materials such as concrete and rendered surfaces. For perfect result, finish the primed surface with Finngard Clean facade paint or other paints suitable for organic aggregate surfaces, giving the masonry facades protection and a great appearance.
