Universal paint-primer Farbex

The surface is prepared according to DSTU-N B A.3.1-23:2013 and DSTU-N B B.2.6-212:2016.

The surface must be dry – the humidity of the surface on all stages of preparation and paint works must be less than 5% for cement and cement-sand surfaces and less than 1% for gypsum ones.

The surface must be clean from chalk and lime whitewashings, grease and oily stains, and other contaminations, efflorescence, dust (including abrasive dust after polishing plasters and stuccos), old paint products and wallpapers (which stick to the surface not secure), polymer adhesives, and runs of construction mortars or composites.

Mineral surfaces must be hard, without fragile parts or edges. The base materials like plaster, stucco, insulating or adhesive elements must be completely dry and be ready for priming and coating with acrylic water-based products.

Parts of the surface infected with mould or fungi must be removed: first mechanically and then treated with antiseptic for mineral surfaces TM Farbex.

Remove contaminations, infections, old coatings, or fragile parts with a wire brush, a spatula, a scratcher or with a polisher.  

Correct appeared defects with Plaster TM Farbex (depending on the character of the defects).

Existing metal elements in the base surface or those that will be used after painting must be made of galvanized or stainless steel. When you use iron elements, they must be initially protected against corrosion with special primers or other products.

Check the compatibility of the products on a small area following technical recommendations or specialists’ consultation before you use other products (an adhesive, an antiseptic, a plaster, etc.).

Follow the directions precisely (especially drying period and subsequent treatment) when further priming and painting construction mortars or products. For example, fresh cement plasters must not be treated for 28 days, fresh concrete - 3 months, the surfaces of insulating systems -  7 days.

Providing maximum exploitation resistance and better decorative effect, depending on the type of surface, it must be primed:

Wooden porous surfaces – with acrylic wood-protective primer TM Maxima. Attention! The primer raises the wood fibers, which is why the surface must be polished before applying the paint.

Mineral surfaces – with acrylic deep-penetrating primer TM Farbex.

Hard types of OSB, wood chip boards, fiber boards, wallpapers, hard old paint coatings need no priming before applying the paint.

Take into account recommendations about priming construction mortars or products. If necessary, call the specialists of POLYSAN.

The paint-primer is ready to use and needs no dilution. Stir the paint thoroughly before use.

The consumption of paint-primer on porous and rough surfaces can be higher. The precise consumption is determined by a test application on a small area on the surface.

We recommend continuously applying in one direction with the same consumption. When you carry out an application on a large area and/or during a long period, we recommend stirring the paint-primer from time to time. We do not recommend keeping the container with the product open for a long period.

Carry out the application at the temperature of the air and the surface from + 5 ºС until +35 ºС and relative air humidity less than 80 %. Do not apply the paint under direct sunlight, strong wind, frost and precipitation.

Remember! Mineral surfaces are porous, and the consumption of the product can increase.

After application, the coating shall not be affected by precipitation or subzero temperatures for 24 hours.

Carry out subsequent works after 24 hours.

The tools must be recommended for water-based products.

For a quality coating, you must obtain painting skills.

During façade works, we recommend using façade tents and scaffolding.  

Compatibility with other coatings

Depending on the exploitation conditions, it can be used with different primers and finishing coatings and primers. The examples are stated further. Call the specialists of POLYSAN to receive more detailed recommendations.

Previous coating – acrylic water-based products. Subsequent coating – acrylic water-based products or, mineral plasters.

Compatibility of products is recommended for testing on a small area of the surface.

After finishing the work. Wash the tools with water, don't let them dry. The rest of the dry paint can be removed mechanically.
