  • Preparation of the base

    It is carried out in accordance with DSTU-NB A.3.1-23:2013 and DSTU-NB B.2.6-212:2016. The surface of the base must be dry, strong, as well as dense and clean. Before installation, the surface is cleaned of dust, oil stains and other substances that reduce the adhesion of the solution to the base. All weak areas of the base should be removed. Open and deepen the cracks mechanically (depth - 1/2 the thickness of the base, width - 5 mm), prime with an acrylic primer and fill with mortar mixture VF 250. To ensure better adhesion of the screed to the surface, surfaces with a high absorption capacity should be pre-treated with primers, in accordance with appointment. Installation of screed is possible no earlier than 4 hours after priming.

  • Preparation of the solution

    Pour water into a clean container (water temperature from +15 °C to +25 °C) at the rate of 0.14-0.17 l per 1 kg of dry mixture, gradually add the dry mixture and mix with a mixer at low speeds until a homogeneous mass is obtained without lump Keep the solution mixture for about 5 minutes, then mix again. An overdose of water leads to delamination of the mixture and reduces the mechanical strength of the solution.

  • Recommendations

    If there are deformation seams in the bedding layer, it is necessary to duplicate them on a freshly installed screed. In addition to the detailed information on how to use the material, when working with it, you should be guided by the current regulatory documents for arranging floors. In the case of using the material in conditions not considered in this technical description, it is necessary to independently conduct tests or consult the manufacturer. VF 250 screed contains cement, which causes an alkaline reaction at the moment of hydration, so it is necessary to protect eyes and skin when working. If the solution mixture gets into the eyes, they should be immediately washed with running water and consult a doctor.

  • Execution of works

    Put the mortar mixture on the surface of the base, distribute it evenly to the level specified by the beacons, level it with a slat or rule. If necessary, rub. When performing "floating" floor screeds, for example, on a soil base

  • Packaging

    Paper bags with an inner polyethylene layer of 25 kg.

  • Storage

    The mixture must be stored in the company's airtight packaging in a dry room, on pallets. The shelf life is 12 months from the date of manufacture indicated on the package.

  • Cost

    On average, 2.0-2.2 kg of screed is used per 1 m2, with a layer thickness of 1 mm.
