Tikkurila Panssari Akva

Tikkurila Panssari Akva is a waterborne acrylate paint for metal surfaces, in a semi-matt finish.

Best Uses

Tikkurila Panssari Akva is suitable for use on sheet metal roofs and walls, steel structures, such as water channels, down pipes and protective sheets.

Tikkurila Panssari Akva is suitable for direct application on surfaces previously painted with alkyd or acrylic paints and on industrially-coated steel sheets, such as PVC, pural, polyester, acrylic. Untreated zinc-coated steel roofs and aluminum and steel surfaces must be first primed with Tikkurila Rostex Super Akva. Aluminum surfaces must be roughened before priming.

Application

Application conditions
The surface to be painted must be dry and warmer than the surrounding air. During painting and drying, the temperature of air, the surface and paint must be above +5 °C and the relative humidity of air must be below 80%. The drying rate is strongly affected by the relative humidity of air, temperature and wind speed. The temperature of the surface may not exceed +40 °C so that the water does not evaporate too quickly. Otherwise, porosity, bubbling and weakened adhesion, for example, could occur in the paint. When maintenance painting, avoid conditions where the paint dries quickly (hot and windy conditions). The application time of Panssari Akva can be extended slightly by thinning the paint with water up to 10%. Excessive thinning and painting under unfavorable conditions may cause the paint to sag. Plan the painting operation so that the paint film has enough time to dry before the evening dew. Do not paint if there is a high chance of rain.

If necessary thin up to max. 10 % with water.

Surface preparation
Previously painted/industrially coated surfaces: Remove any rust (until grade St2) and loose coating/paint with a scraper and wire brush. Clean the surfaces with Tikkurila Panssaripesu, removing any dirt, grease, oil, wax and other impurities according to the product instructions. Use a brush when cleaning. Rinse the surfaces carefully, preferably with a pressure washer. Prime bare metal surfaces twice with Tikkurila Rostex Super Akva anti-corrosive primer.

Unpainted, zinc-coated steel and aluminum surfaces: It is recommended to paint new zinc-coated sheet metal roofs after one winter, at the earliest. Best adhesion is achieved with a mechanically or chemically roughened zinc-coated surface that has been dimmed by the weather. First, clean any rusty areas with a scraper and wire brush until grade St2. Remove any white rust by brushing or grinding. Remove dirt, water-soluble salts, grease and oil from the surface with Panssaripesu cleaning agent and a brush. Rinse carefully with water and allow to dry well. Aluminum surfaces must be roughened before painting. Prime zinc-coated surfaces and roughened aluminum and steel surfaces twice with Tikkurila Rostex Super Akva or once with Tikkurila Rostex Super.

Industrially coated surfaces: Determine the type, condition and adhesion of the original coating. Check with the manufacturer of the coating whether the coating can be maintenance painted and if it needs a separate primer.

Painting
The pretreated surfaces (see Pretreatment) are painted with 1–2 coats of Panssari Akva to a dry-film thickness of 50–80 μm. Pay attention to choosing a suitable brush. Recommendation: Tikkurila roof/ceiling paint brush T6. Spray application is recommended for roof tile profile surfaces.
The slipperiness of the painted surface can be reduced by adding 1/3 liters of Tikkurila Liukueste powder to 10 liters of paint. When using Liukueste powder, apply two coats of paint such that the second coat includes the anti-slip material.
