REDBAG 333 is a fine-grained, easily spreadable self-leveling compound intended for leveling (manually or mechanically) concrete bases and floor screeds made of cement-sand, cement-lime and gypsum mortars inside buildings on rigid bonded bases. It can be used for installing heated floors. It is used both for leveling screeds in which any underfloor heating system is installed, and for installing a floor heating system with electric mats installed in the REDBAG 333 self-leveling compound itself. The compound is ideal for preparing the surface for laying ceramic tiles, linoleum, carpet, and other floor coverings that require a perfectly horizontal surface. The recommended layer thickness is 3-15 mm. Compressive strength 20 MPa (M200).

The base must be dry, not frozen, strong (not less than 20 MPa (M200)), capable of bearing loads, free from dust, dirt, oils, greases, lubricants, old paint residues, wax and other substances that reduce adhesion, have uniform water absorption, and meet the requirements of DSTU-N B A.3.1-23:2013, DSTU-N B V.2.6-212:2016, SNiP 2.03.13-88. Remove weak areas of the base.

Before using the REDBAG 333 mortar mixture on already arranged cement-sand, cement-lime and gypsum bases, it is imperative to clean the dust and treat it with a primer for hygroscopic surfaces REDBAG INTERLACE.

The concrete base should not be subject to shrinkage after arranging the screed, therefore it must be no younger than 3 months from the moment of laying the concrete, and the residual humidity of the concrete must be below 4%. Cast concrete bases have a smooth surface and low moisture absorption, therefore, after cleaning before finishing, they must be treated with an adhesive primer for dense, smooth, low or no moisture absorbing bases - REDBAG SUPERSTICK.

Pour the REDBAG 333 dry mix into a container with clean water (at the rate of 5-5.25 l of water per 25 kg or 200-210 ml per 1 kg of dry mix), mix using a construction mixer until a homogeneous mass without lumps is formed. Leave for 3 minutes and mix again. The prepared mix must be used within 30 minutes from the moment of mixing.

Do not add other materials to the prepared solution.

Attention! REDBAG mixes are created on the basis of modern high-tech recipes using the latest additives from world manufacturers.

When preparing the mix, use water only in the volume indicated on the packaging!

Work should be carried out at a base temperature of +5 °C to +30 °C. The layer thickness per application should be from 3 mm to 15 mm. When arranging a floor using the REDBAG 333 self-leveling mixture, it is necessary to follow the rules for arranging expansion joints: structural, insulating and shrinkage. Structural expansion joints should be used in structural joints of buildings and if necessary to reduce the effect of thermal expansion of materials. If such joints already exist in the base, they must be duplicated in the floor being arranged. Insulating joints are used to separate the screed being laid from contact with load-bearing and enclosing structures (walls, columns, stairs, etc.), which can limit floor deformation. Insulation joints are made using an elastic layer (foamed polyethylene, thin polystyrene foam). They are also used in places where the thickness of the base changes, in places where different floors meet, as well as to separate rectangular fragments of the base in rooms with a complex geometric shape. Shrinkage joints should divide the floor into fields with an area of no more than 20 m2 with a side length of up to 5 m indoors, 16 m2 with a side length of up to 4 m outdoors and in rooms with heated floors. In corridors, shrinkage joints are arranged at intervals of 2 corridor widths.

Pour the prepared mortar mixture onto the prepared base and distribute it on the surface using a rubber measuring bar, notched trowel or other tools. To remove air from the freshly applied mortar, it is necessary to “roll” its surface with a needle roller (the length of the needles is 2 times the thickness of the layer). The thickness of the mortar layer above the electric mats must be at least 10 mm. The hardening time of the mortar depends on the temperature and relative humidity of the air. Under normal conditions, namely at a temperature of 20±2 C and a relative humidity of 55±5%, technological movement on the floor is possible after 8 hours. The next layer can be applied either in the period from 24 to 72 hours after applying the first layer, or after 14 days! Installation of coverings using water-based adhesives should be carried out after 72 hours, provided that a heating system is installed in the floor, tiles should be laid on elastic adhesive TM REDBAG, and installation of coverings using adhesives based on organic solvents should be carried out after 7 days. To prevent destruction, the floor heating system should not be turned on earlier than 28 days after installation of the floor.
