Instructions for use the following. The work must be done in a dry room, where the humidity of the air is not more than 75%, the temperature is not less than 5 ° С. It is possible to pour only on a concrete base, the casting period of which is longer than 3 months or cement sand - laid at least 1 month ago, the surface temperature - from 5 ° С, humidity - up to 6%.

Before work, the surface of the future floor is cleaned from dust, dirt, oils and other foreign substances. Large cracks and holes need to be repaired - more than 24 hours before the main fill. To do this, you can use the products "Volma-Nivelir Express" a thicker consistency, reducing the standard water flow. The remaining metal elements in the floor (tubes of batteries, water and gas supply, grounding) must be protected from corrosion, for example, with silicone or sealant before pouring. The joints of the walls with the floor must be supplied with foam polystyrene gaskets. or other polymeric insulating material.

The thickness of the poured layer is indicated with the help of portable metal or plastic beacons-rappers with a scale. You can make a homemade leveling scale of improvised means, so it will be cheaper.

Before pouring, the floor is primed with a conventional paint roller with a long handle. You can use Volma Universal primer or any other for internal deep penetration works.It is enough to process smooth surfaces 2 times, porous at least 2-3 times with an interval of 4 hours.

Volma self-leveling floors can be used for hand or machine application. If an automatic station (unit) is used when pouring, then after it is turned on, the dry mixture is poured into the bunker and the required solution density is set at the outlet by adjusting the water supply. To check the correct density, you can pour 1 liter of the mixture onto a non-absorbent surface - the spot should be about 0.5 m in diameter.

During manual pouring, the mixture is poured into a container with water and mixed with a mixer, a drill with a nozzle in the form of a whisk or manually until a homogeneous mass is formed within 5 minutes. The screed is then settled for 3 minutes and mixed again. It is necessary to avoid overflow of water and use only those proportions that are specified in the instructions. If a dry mixture or water is added to an already mixed and aged solution, then it loses its beneficial properties. The prepared mass should be used within 60 minutes.otherwise it starts to thicken.

The liquid mixture is poured onto the prepared area evenly and continuously, it should be done in no more than 1 hour to avoid solidification of the solution. Then air bubbles are removed from the surface with a needle roller. After that, proceed to a similar work in the next section.

If the Volma-Nivelir Express mixture is poured onto the “warm floor” system, then the recommended layer thickness is 40 mm, if the heating is already installed in the base to be poured, the layer can be from 5 to 100 mm.

The solution dries on average 40-60 minutes after pouring, but the first 5-6 hours should be avoided to step on it or subject to other mechanical influences, and it is recommended to load with heavy objects only after 3 days. In the room for the first 2 days, it is necessary to observe the temperature regime of 5 - 25 ° С, to ventilate the room.
