GRUNT EKO is an acrylic primer for preparing substrates before painting, wallpapering and decorative finishing, inside and outside buildings, including insulation systems.
What a primer does
Three things at once: it binds a surface that dusts or crumbles, it improves adhesion for the next coat, and it evens out the substrate's absorbency. The last directly cuts paint or render consumption: an unprimed wall drinks the first coat.
When the basic one is enough
It is the working choice for ordinary substrates in reasonable condition: concrete, prepared brickwork, rendered walls, and indoors plasterboard, gypsum and chipboard. If the surface is not coming away in handfuls and has no eroded patches, a deep-penetrating product is overkill and the result is the same.
When to choose something else
Friable render, old filler, eroded brick: those need a deep-penetrating primer that binds dust through the layer, not only on the surface. Decorative render calls for a keying primer with quartz filler.
Consumption and storage
The primer is ready to use and is not diluted. It goes on in a single coat, wetting the surface evenly, at 100–200 g/m². It dries in 1–2 hours depending on temperature, and paint can go on after 2 hours. Fresh cement and cement-lime plasters are primed after 3–4 weeks, concrete after a month. Packs of 5 and 10 kg, shelf life 18 months.
How much you need
Example: how much area one package covers in one coat at 100–200 g/m².
- 5 kg — 25–50 m²
- 10 kg — 50–100 m²
Application
Preparing the substrate
the substrate is dry, sound and clean: free of dust, grease and flaking coatings;
old chalk whitewash is removed completely;
fresh render needs at least 28 days.
Dilution
no dilution needed;
stir before work.
Application
apply by brush, roller or spray;
one even coat with no gaps;
application temperature +5…+30 °C.
Next
apply the next material once it has dried fully: a coat takes up to 2 hours;
rinse tools with water straight away;
store above freezing, do not let it freeze.
FAQ: choosing a primer and consumption
Can I paint without priming?
The data sheets for POLIFARB interior and facade paints call for priming the prepared surface. The primer strengthens the substrate, improves paint adhesion and reduces paint consumption.How does it differ from a deep-penetrating primer?
They are used for the same jobs. The data sheets describe PROFI GRUNT and GRUNT CONCENTRATE 1:4 as deep-penetrating; GRUNT EKO's does not.How much area does a 10 kg can cover?
At 0.1–0.2 kg/m², 50–100 m² in one coat, depending on the substrate and application method.How long does the primer take to dry?
1–2 hours depending on temperature. Paint can go on after 2 hours.Is it suitable under decorative plaster?
Yes, the data sheet lists preparing substrates for decorative protective finishes.Can it be used on a facade?
Yes, it is for exterior and interior work, including external wall insulation systems.
