Description

GRUNT CONCENTRATE 1:4 is a deep-penetrating acrylic primer supplied as a concentrate. It prepares substrates before painting, decorative finishing and filling, inside and outside buildings.

What a concentrate buys you

One litre is diluted with four of water, so a 2 L bottle makes 10 L of working solution. On a large site that changes the logistics: two bottles instead of ten cans of ready-mixed primer, and leftovers are easier to store. The standard dilution is 1:4 (1 part primer to 4 parts water); where needed, the surface can also be treated with the undiluted concentrate.

Why prime at all

A primer does three things at once: it binds a surface that is dusting off, it improves adhesion for the next coat, and it evens out how much the substrate absorbs. That last one saves money directly: unprimed render drinks the first coat of paint, and two coats turn into three.

Which substrates

Concrete, prepared brickwork, rendered surfaces, insulation systems, and indoors only gypsum, plasterboard and chipboard.

Consumption and packaging

100–200 g/m² in a single coat, and one coat is all it needs. 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. The milky-white colour shows where you have already been, so nothing gets missed. Packs of 1 L and 2 L, shelf life 18 months.

How much you need

Consumption is counted on the working solution: 150 g/m² in one coat. The concentrate makes five times its own volume.

  • 1 kg of concentrate → 5 kg of solution → about 33 m²;

  • 2 kg of concentrate → 10 kg of solution → about 67 m²;

  • allow 20–30 % extra on a very porous substrate.

Application

Preparing the substrate

  • the substrate is dry, sound and clean: free of dust, grease and flaking coatings;

  • old chalk whitewash is removed completely: a primer will not bind it;

  • fresh render needs at least 28 days.

Dilution

  • dilute with clean water 1:4, one part concentrate to four parts water;

  • use a weaker ratio on a very porous substrate;

  • stir until uniform.

Application

  • apply by brush, roller or spray;

  • one coat, evenly, with no gaps: the milky colour shows the covered area;

  • application temperature +5…+30 °C.

Next

  • paint or fill after 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: dilution, consumption and substrates

  • How much water do I add?
    Four parts water to one part concentrate. A 2 kg bottle makes 10 kg of working solution.

  • How much area does a 2 kg bottle cover?
    About 67 m² in one coat at 150 g/m² of working solution.

  • Can it be used undiluted?
    No. Undiluted concentrate forms a film on the surface that paint adheres to less well.

  • Will it bind old whitewash?
    No. Chalk whitewash must be removed completely; primer will not hold on it.

  • How soon can I paint?
    Once it has dried fully; a coat takes up to 2 hours.
