A fully waterborne coating method for metal surfaces

Rostex Super Akva and Panssari Akva form a fully waterborne method for coating sheet metal roofs and other metal surfaces, without compromising on the quality and durability of the paint coat.

Effective and durable protection from rust

Rostex Super Akva contains a functionally modified acrylate binder specifically designed for metal surfaces. It provides excellent adhesion. 

Suitable for outdoor and indoor use

Use Rostex Super Akva for priming sheet metal roofs, drainpipes, cinder sheets, and other exterior metal surfaces. This waterborne product is also ideal for interior use, including as a primer for radiators.

APPLICATION DETAILS
Application conditions
The surface to be painted must be dry and warmer than the surrounding air, the temperature of the air at least +10 oC, and the relative humidity of the air below 80 %. The product is recoatable with water-borne paints the same day after 4 hours if the temperature of the air is at least +10 C and the relative humidity of the air below 80 %. In other cases to be recoated the following day.

The temperature of the painted surface may not exceed +40C, because otherwise the water in the product evaporates too quickly and porosity, weakening of adhesion, blistering etc. will occur.
Plan the painting work so that evening dew does not wet the surface when it is drying.
Preparation
Unpainted surfaces:
Clean water soluble white rust protective agent, dirt, water soluble salts, oil and grease from unpainted surfaces with Panssaripesu Roof Cleaning Agent and brush. Rinse thoroughly with water and allow to dry. Remove white rust/rust by grinding or wire brushing, steel surfaces to preparation grade St2. Roughen aluminium surfaces.
New zinc-coated sheet metal roof is recommended to be painted earliest after one winter. Best adhesion is achieved to already faded, mechanically or chemically roughened zinc-coated surface.

Previously painted surfaces:
Wash down the surface with Panssaripesu Roof Cleaning Agent and brush, rinse carefully with water and allow to dry. Remove loose paint and rust from previously treated surfaces by scraping or wire brushing (steel surfaces to St2). Grind the border of the cleaned and solid paint area to ensure the adhesion of the finish. Sand matt those areas of old paint surface that will be painted.

Painting
Stir the paint well before use. Apply with brush or spray. The dry film thickness of a single coat should be 60-80 µm. Pay attention to angles and folds on metal surfaces, the dry film thickness should be the same on these parts. Rostex Super Akva is applied on bare metal surfaces. Use water-borne Panssari Akva or, e.g, Luja in interior rooms as a topcoat. Avoid painting in hot sun light , because the paint dries too quickly and does not stabilize enough.
Cleaning of tools
Clean tools with water or with Tikkurila Pensselipesu Tool Cleaner.
Maintenance instructions
The painted surfaces must be handled with care, because the paint will achieve its final hardness and durability in approx. 2 weeks under normal conditions. Soon after the treatment the surface can be cleaned lightly with a soft brush, damp cleaning cloth or mop. At the earliest 1 month after painting, dirty surfaces can be cleaned with Tikkurila Huoltopesu (1 part Huoltopesu, 10 parts water). Clean stains and very dirty surfaces with a stronger solution of Huoltopesu (1:1). After washing rinse surfaces and allow to dry.

Instructions

Consumption varies depending on the surface to be treated and its condition. Absorption is affected e.g. by the surface roughness, moisture content level of timber and porosity. For example, log surface that has been untreated for a long time takes a lot more wood finish than a new surface to be treated.

When calculating the consumption, note that the consumption for round logs is 1.5 times higher than normal. Please also note the corner joints in the surface area.

Rounding up

As the filling rate is usually 90% (space for tinting), it is good to round up the liter amounts and reserve enough of the product so that the work is not interrupted unnecessarily, and colour will be even.
