REDBAG FORWARD MACHINE-APPLIED GYPSUM PLASTER is a mixture based on gypsum binder, polymer additives, and lightweight perlite filler. It is designed for mechanized leveling (using mortar mixers) of walls and ceilings with various types of substrates for further finishing (painting, wallpapering, etc.) inside buildings with a layer thickness of 6 to 35 mm per application. It is used in rooms with normal humidity levels, including kitchens and bathrooms. Maximum filler fraction size: 1.25 mm.

The base must be dry, frost-free, strong, capable of bearing loads, free of dust, dirt, oils, fats, greases, old paint residues, wax, and other substances that reduce adhesion, have uniform water absorption, and comply with the requirements of DSTU-N B A.3.1-23:2013, DSTU-N B V.2.6-212:2016. Remove any weak areas of the base.

Ceramic brick walls and walls that are already finished with cement plasters have high moisture absorption, so after cleaning, they must be treated with REDBAG ADHESIS deep penetration primer before plastering.

Cast concrete walls have a smooth surface and low moisture absorption, so after cleaning, they must be treated with REDBAG SUPERSTICK adhesive primer for dense, smooth substrates that absorb little or no moisture before plastering. Walls made of silicate brick, which is smooth, must also be treated with REDBAG SUPERSTICK adhesive primer before plastering.

Walls made of aerated concrete blocks should be cleaned of dust and treated with a vapor-permeable primer for hygroscopic surfaces, such as REDBAG POROBAR or REDBAG INTERLACE.

For mechanized application, prepare the plastering station for operation. Set the water dispenser flow rate of the plastering station to 650-700 l/hour.

Do not add any other materials to the prepared solution.

Work should be carried out at a base temperature of +5 °C to +30 °C.

When using a mechanized method of applying plaster, any plastering station can be used. Plastering walls with a nozzle is usually done from left to right and from top to bottom, holding the spray gun perpendicular to the surface at a distance of 10-30 cm and forming strips about 100 cm wide. The thickness of the plaster layer is adjusted by the speed of the spray gun. The work is carried out in such a way that the trace of the plaster spray moves along the lower edge of the strip of the already applied solution, using the “caterpillar” method. Each subsequent strip is applied with an overlap of 2-3 cm over the previous one. Approximately 60-100 minutes after mixing the mixture, level the layer of applied material with a metal trapezoidal ruler, cutting off irregularities and filling in depressions. If the surface is being prepared for painting, then after leveling (approximately 15 minutes), moisten the plaster surface with water and rub it with circular movements using a sponge float to remove minor irregularities. After a short wait until a matte surface appears, smooth the plaster with a wide trowel or metal float. To obtain a smooth surface, within 24 hours, but not earlier than 4-5 hours after mixing the mixture, moisten the plaster surface generously with water and smooth it with a trowel or smoothing tool.

During breaks in work lasting more than 20 minutes and after completion of work, the tool must be cleaned and rinsed with water.

The thickness of a single layer of plaster should be between 6 and 35 mm. Surfaces with differences in level greater than 35 mm should be leveled in several layers, with the next layer applied immediately after the previous one has hardened (approximately 4-5 hours after mixing the mixture, depending on the water absorption of the surface and the temperature in the room). When applying several layers, do not level the previous layer.

At low temperatures, direct heating of the plaster surface is not allowed. To speed up the drying of the plaster, ensure adequate ventilation of the room.

0.9 kg per 1 m² with a layer thickness of 1 mm. The consumption of the mixture depends on the unevenness of the base and the skills of the contractor.
