REDBAG 116 - adhesive mixture intended for internal and external cladding of walls and floors made of strong concrete, brick, cement-sand, cement-lime, gypsum and other mineral bases, including those subject to deformation (i.e.: A. Bases subject to mechanical influences - vibrations through the foundation or from equipment, as well as partitions assembled on a profile system - plasterboard, gypsum fiber, OSB boards. B. Bases subject to atmospheric or temperature influences, namely sudden changes in temperature, but not higher than +90 ºС - stoves and fireplaces, facade insulation system, heated floors, even when it is necessary to lay tiles on an electric mat, basements, terraces, balconies, roofs that are in use, etc. C. Bases that have a layer in their design that "is "floating" - often the insulation is extruded polystyrene foam, or has a separate layer - cardboard, polyethylene, bitumen substrates ...) tiles of any type and size from 800×800 mm (0.64 m²) to 2000×2000 mm (or an area of no more than 4 m2 with the maximum size of one of the sides not more than 2400 mm). Cladding is allowed in places with heavy traffic and high mechanical loads.

Adhesion strength to the base of at least 2.0 MPa.

The base must be perfectly flat (recommended tolerance ± 3mm), dry, not frozen, strong, 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. Remove weak areas of the base, and level surface irregularities over 3 mm using the REDBAG 116 mixture 24 hours before starting work. Surface irregularities of up to 3 mm can be leveled when tiling.

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

Bases made of cement screeds, cement and cement-lime plasters should not shrink after laying tiles, so they must be no younger than 28 days from the moment of their installation, and their residual moisture must be below 4%. Such substrates have high moisture absorption, so after cleaning before finishing, they must be treated with a deep penetration primer REDBAG ADHESIS.

Floors arranged using "Self-leveling floor mixture REDBAG 333" (or similar cement mixtures) must not be subject to shrinkage after laying tiles, therefore they must be no younger than 28 days from the moment of their arrangement, and their residual humidity must be below 4%. They must be sanded with sandpaper, cleaned of dust and must be treated with a deep penetration primer REDBAG ADHESIS.

Gypsum wall block bases, anhydride screeds, floors arranged with the "Self-leveling gypsum floor mixture REDBAG 335" (or similar mixtures) must be completely dry (with a residual humidity of less than 1%) before finishing. They must be sanded with sandpaper, cleaned of dust and must be treated with a deep penetration primer REDBAG ADHESIS.

Aerated concrete must be cleaned of dust and treated with a vapor-permeable primer for hygroscopic surfaces REDBAG INTERLACE before finishing.

Pour the REDBAG 116 dry mixture into a container with clean water (at the rate of 7.5-8 l of water per 25 kg or 300-320 ml per 1 kg of dry mixture), mix using a construction mixer until a homogeneous mass without lumps is formed. Leave for 3 minutes and mix again. REDBAG 116 adhesive solution is thixotropic, and provided that the water is accurately dosed, when facing vertical surfaces with large and heavy decorative tiles, additional mechanical fastening of the tiles is not required. The adhesive solution is well distributed under the tile.

Do not add other materials to the prepared adhesive solution.

Do not pre-wet the tile and the base! The adhesive layer after laying the tile should be at least 5 mm and not more than 10 mm. The requirement when laying large-format tiles (with an area of more than 0.64 m²) is that the adhesive must completely cover the back of the tile to avoid the formation of voids, otherwise the strength and durability may be impaired. Therefore, for large-format tiles with an area of more than 0.64 m², it is imperative to use void-free laying with double-sided application using the following technology.

To achieve good adhesion, first apply a thin layer of adhesive to the base with the smooth side of the notched trowel, then immediately apply and distribute the adhesive over the base using a notched trowel with teeth of at least 10 mm. The spatula should be held at a 45º angle to the surface. The adhesive should be applied in straight lines (not circular), parallel to the shorter side of the tile. This application creates more holes in the adhesive layer for better air expulsion.

Next, apply and spread the adhesive on the back of the tile in straight lines, also using a notched trowel with 4mm teeth. The adhesive on the back of the tile should be spread so that when gluing, the direction of the applied adhesive on the substrate and on the back of the tile is parallel (to allow air to escape).

When laying large-format tiles, use special carriers with suction cups.

When laying, the tile should be pressed firmly to ensure a good fit. The adhesive must completely cover the back of the tile to avoid gaps, otherwise the strength and durability may be compromised. To remove air and ensure a secure bond, walk over the surface of the tile using a surface vibrator or manually with a special rubber trowel for grouting, starting from the center and moving towards the edges in the direction of adhesive application, i.e. parallel to the shorter side, to ensure that all air is removed from under the tile.

When laying tiles on facades, the designer must assess whether additional mechanical safety fasteners are required.

After laying the facing tiles, any remaining adhesive mortar should be removed with a damp sponge. The width of the joints between the tiles should be at least 2 mm.

The pot life of the mortar is 3 hours. The tiles must be laid no later than 45 minutes from the moment of applying the adhesive solution to the base. The adjustment of the tiles and the application of the tile leveling system (SVP, DLS, TLS) must be carried out within 45 minutes after its laying. Technological movement on the floor, dismantling of the tile leveling system and grouting of inter-tile joints is possible 48 hours after laying the tiles. To prevent destruction, the floor heating system can be turned on no earlier than 28 days after the floor is installed.

1 kg/m² at a layer thickness of 1 mm.

*The consumption of the mixture depends on the unevenness of the base and the skills of the performer.
