|DESCRIPTION||Semi-matt acrylic paint for metal surfaces.|
Can be used directly on surfaces previously painted with alkyd or acrylic paints and industrially coated steel sheets (PVC, PURAL, POLYESTER, ACRYLIC).
Untreated zinc-coated steel roofs and aluminium and steel surfaces must be primed with Rostex Super Akva or Rostex Super Metal Primer. Aluminium surfaces must be roughened before priming.
More information in Tikkurila Roof Painting Guide.
|RECOMMENDED USES||Metal-sheeted roofs and ceilings, steel constructions like water channels, down pipes and protective covers.|
|Base paints||A and C|
|Colour Range||Can be tinted according to the Tikkurila Roof Paints colour card. |
Also most of the colours in Tikkurila Wooden Facades colour card are available, also Ruukki colour card.
Standard colours: Black (0202), Old Copper (0296), Iron Red (0384),
Graphite Grey (0514)
|Coverage||approx. 8 m²/l one layer (For spray application corresponds to a wet film thickness of approx. 100-125 µm)|
|Can sizes||Base paints A and C: 0,9 l, 2,7 l, 9 l, 18 l |
Standard colours: 10 l.
|Mixing ratio||If necessary thin up to max. 10 % with water.|
Brush (Tikkurila brush T6) or spray.
For airless spay application:
- nozzle 0,013"-0,017" (nominal angle 40°- 50°)
and thinning by max. 10 % by volume if necessary
|Drying time at 23°C and 50% relative air humidity||Touch dry after 1-3 hours, recoatable after 24 hours.|
|Solids volume||approx. 40%|
|Density||approx. 1,0 kg/l depending on shade, ISO 2811|
|Storage||Protect from frost!|
|Application conditions||The surface to be painted must be dry and warmer than the surrounding air. During treatment and drying the temperature of the air, surface and product must be at least +5 º C and the relative humidity of the air below 80 %. The relative humidity of the air, temperature and wind speed have a strong impact in drying time. |
The temperature of the surface may not exceed +40oC, otherwise the water will evaporate too quickly. This may cause e.g. porosity, bubbling and weakened adhesion. Especially when maintenance painting conditions should be avoided, under which the paint dries quickly (warm and windy weather). The application time of Panssari Akva can be extended slightly by thinning the paint with water by max. 10 %. Excessive thinning and painting under unfavorable conditions may cause sagging of the paint. Plan the work so that the paint surface has enough time to dry before dewfall. Do not paint if the risk of rain is imminent.
|Preparation||Previously painted surfaces/industrially coated (coil-coated) surfaces: |
Remove possible rust (to St2 degree) and remove loose coating/paint with a scraper and wire brush. Clean the surface with Panssaripesu Roof Cleaning Agent from dirt, grease, oil, wax etc. according to instructions using a brush. Rinse the surfaces carefully, preferably with a pressure washer. Prime bare metal areas with Rostex Super Akva or Rostex Super Metal Primer.
Unpainted zinc-coated, steel and aluminium surfaces:
Paint new zinc-coated sheet metal roof at the earliest the following year after the installation. Best adhesion is achieved to already faded, mechanically or chemically roughened zinc-coated surface.
Remove possible rust (to St2 degree) by scraping and wire-brushing. Remove possible white rust by brushing or sanding. Remove dirt, water soluble salts, grease and oil from the surface with Panssaripesu Roof Cleaning Agent and brush. Rinse carefully with water and allow to dry. Roughen the aluminium surfaces before painting. Prime the zinc-coated metal surfaces and roughened aluminium and steel surfaces with 1 coat of Rostex Super Akva or Rostex Super.
Industrially coated surfaces:
Find out the type, condition and adhesion of the original coating. Check the maintenance from the coating manufacturer and the need for a separate primer. For more detailed instructions see Tikkurila Roof Painting Guide and Tikkurila website.
|Painting||Pre-treated surfaces (see Preparation) are painted with Panssari Akva 1-2 times.The recommended dry-film thickness is 50-80 µm. Pay attention in choosing the correct brush. Recommendation: Tikkurila roof paint brush T6. Roof tile profile surfaces are recommended to be painted by spray. |
The slipperiness of paint surface can be reduced by adding Non Slip Agent into the paint, 1/3 l of powder into 10 l of paint. When using the Non Slip Agent there has to be two paint layers in the paint system and Non Slip Agent is included in the second layer.
Surface painted with Panssari Akva can be recoated with Panssari Akva.
|Cleaning of tools||Clean tools with water or with Tikkurila Pensselipesu (Tool cleaner. Remove hardened paint with Tikkurila Tool Cleaner.|
|Maintenance instructions||After 1 month the surface can be cleaned with Huoltopesu Maintenance Cleaner (mixing ratio: 1 part of Huoltopesu to 10 parts of water). Clean soiled surfaces and stains with a stronger Huoltopesu solution (1:1). Rinse the surface carefully after maintenance and let it dry.|
