Preparation of the base

When preparing the base, it is necessary to comply with the requirements of DSTU-NB A.3.1-23:2013 and DSTU-NB V.2.6-212:2016. The base must be strong, dry and free from dust, dirt, wax, paint and other substances that reduce the adhesion of the solution to the base. Weak layers must be removed. Surfaces that strongly absorb liquid should be primed with a deep-penetrating acrylic primer and left for at least 6 hours. Weakly absorbent surfaces should be primed with an acrylic primer and left to stand for at least 4 hours. Mold, microorganisms, and other biological formations must be mechanically removed to the depth of the lesion, and an aqueous antiseptic should be used to disinfect and protect the surface from biological formations. To ensure better adhesion of the plaster to the surface for porous concrete, as well as gypsum and smooth concrete surfaces, treat the concrete-contact primer with quartz filler and wait for at least 8 hours.
Preparation of the solution

The mixture must be poured into a container with a previously measured amount of water in the proportion of 0.50-0.55 l per 1 kg of the mixture (12.50-13.75 l per 25 kg bag). Mix with a drill with a nozzle or by hand to a homogeneous creamy state, until lumps are completely removed, leave for 2-3 minutes and mix again. The mixture must be used within an hour. To prepare the mixture, you need to use only clean water with a temperature of +5°C to +30°C and only stainless containers and tools cleaned of the remains of hardened solution.
Recommendations

Work must be performed at an air temperature of +5°С to +30°С. The most effective result is achieved at a temperature of +20°С and a relative humidity of 60%. In other conditions, the working parameters of the mixture may change. In the case of using plaster in non-standard conditions or for other purposes, it is necessary to conduct tests yourself or consult with the manufacturer. The manufacturer is not responsible for improper use of the material, as well as its use for other purposes and conditions not provided for in the technical description. When working, it is necessary to protect the eyes and skin. If the solution mixture gets into the eyes, they should be immediately washed with running water and consult a doctor.

Execution of works

The temperature of the base and the environment must be at least +5°С. The time of working with the solution is up to 120 minutes. Do not use the setting material anymore, adding water or additional agitation only from the outside improves the suitabil
Packaging

Paper bags with an inner polyethylene layer of 25 kg.
Storage

The mixture must be stored in a branded sealed package in a dry room, on pallets. The shelf life is 12 months from the date of manufacture indicated on the package.
Cost

Mixture consumption per 1 mm layer thickness — ~ 0.80 kg/m².
