Steps for applying paint to concrete
Preparation of the substrate:
The substrate should be seasoned, sound, free of dust, oil stains, grease and peeling coats of old paint and free of dirt. The substrate should be dry with no visible traces of moisture or darkening caused by humidity.
Surfaces should be washed with pressurised water with detergent, rinsed and dried before painting.
Mechanically trowelled concrete and smooth, compact surfaces should be roughened first by mechanical grinding, sandblasting or chemically using etching acids to ensure good adhesion and to remove cement laitance.
Absorbent, loosely bound and loose substrates are recommended to be impregnated with AKSILUX.
Moulded, moss- and algae-infested areas should be mechanically cleaned and disinfected e.g. with Aksil's GRZYBOBÓJCA.
Painting:
Before painting, stir the paint. For the first application, dilute the paint with water in the ratio 3:1 (3 parts paint : 1 part water), or 2:1 (2 parts paint : 1 part water) in the case of a very dense substrate. Apply the second coat with undiluted paint, applying 2-3 coats. Apply the next coat after approx. 1 hour. At lower ambient temperatures, the drying time should be extended.
Apply the paint with a brush, roller or spray equipment (airless or airless hydrodynamic and hydrodynamic).
Recommended parameters for hydrodynamic spraying (WAGNER gun):
- nozzle diameter 0.013-0.019 inch e.g. nozzle 513
- spray pressure approx. 175-200 bar
- spray angle 20 - 50 degrees
Thick coatings up to 400 microns wet may also be applied.
Wagner, WIVA and Kremlin units are recommended for spraying.
Water should be used to wash painting tools.
All painting work should be carried out at an ambient temperature of +50C to +300C and preferably at 20 ± 5°C and a relative humidity of up to 60 %.
The freshly applied coating should be protected from rain and frost.
Practical applications that concrete paint has
Concrete outdoors is a generally used durable and relatively inexpensive material. It is used versatilely for fences, walkways, decoration and facades. The aforementioned surfaces dull over time, crumble, become overgrown with moss or algae. To improve the aesthetics of the surface in question, it is advisable to repaint it. AKSILBET concrete paint not only gives an aesthetically pleasing appearance, but also forms a protective layer, which for years to come will serve as protection for concrete surfaces outdoors, where atmospheric factors may strongly affect it.
AKSILBET concrete paints are available in 3 unique metallic shades, thanks to which painting sculptures, decorations, monuments gives them a fresh and original look. On the other hand, basic colours such as ash, white, black or red will work perfectly for utility and fencing elements. For vivid colours and visual effects, we have also introduced blue, green and yellow. In order to tone down a given surface, we can also use paint for concrete in shades of sand, brick, brown or copper.
Paint for concrete AKSILBET is widely used and is an excellent product for protecting and refreshing the surroundings where we live and work.
