(Previous date 30.01.2012)
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.
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),

Standard colours: 10 l.
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
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.
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.
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.
Panssari Akva contains VOC max.140 g/l.
