Application instruction


1. Surface preparation

The surface shall be hard and dry. Clean thoroughly of dust, rust, dirt, coke dross, grease, oil and other dirt.

Clean dirty areas with a dry brush.

To receive a smooth surface without visible places of old coatings (paint or varnish), it shall be totally removed from the surface in mechanical (with a scratcher, a floor scrubber), thermal (a hot dryer, infra-red rays) or chemical way (paint removing treatments).

Previously painted surface (with oil or alkyd paint) shall be sanded for gaining the best adhesion.

Defected surfaces (holes, rends, cracks) shall be filled with Putty for wood ТМ Farbex.

Small defects of mineral surface shall be corrected with Finishing putty TM Farbex.

Metal surface shall be thoroughly cleaned from rust with a metal brush or polishing paper.

The puttied surface shall be polished till it is smooth, remove dust after polishing.

2. Priming

Previously coated wooden surfaces require no undercoating.

Wooden surfaces, which were not undercoated before, shall be treated with Acrylic woodcare primer TM Maxima.

The uncoated mineral absorbing surfaces shall be undercoated with Deep-penetrating waterborne acrylic primer “SuperBase” TM Farbex.

Metal surfaces, which were not undercoated before, shall be undercoated with Anticorrosion primer GF-021 TM Farbex.

3. Applying

Stir the enamel thoroughly before use. The enamel is ready to use.  Excessive diluting causes the quality of the coating.

The temperature of the air and the surface under application shall be from +15 °С till +35 °С and relative air humidity no more than 80%.

Enamel shall be applied with brush, roller or paint blower with 1-2 layers. The next layer shall be applied not earlier than in 4 hours.

The coating takes finally its properties in  3-4 weeks.

It is not recommended to perform an application on working heating systems!

4. Tool cleaning

Clean tools with water after application.
