WALLMIX K-14 adhesive mixture is intended for cladding vertical and horizontal solid non-deformable substrates (concrete, brick, cement-sand and cement-lime surfaces) with tiles with water absorption of at least 0.2% (porcelain stoneware), including large-format floor tiles, inside and outside industrial and residential buildings. It can be used in underfloor heating systems.
In underfloor heating systems, where a heating mat is used and the tiles are laid directly on it, it is necessary to use the elasticized adhesive mixture WALLMIX K-17 or WALLMIX K-27, respectively.
A mixture of cement with mineral fillers and modifying additives.
It is сarried out in accordance with the requirements of DSTU-N B A.3.1-23: 2013 and DSTU-N B B.2.6-212: 2016. The surface must be dry, strong and cleaned from dust, dirt, oil, grease, wax and paint. Fragile surface need to be removed. Highly absorbent substrates must be treated with a deep-penetrating WALLMIX Universal or WALLMIX Interior emulsion before use for 4 to 6 hours. Weak-absorbing and smooth bases before the beginning of work process an adhesive primer WALLMIX Betonkontakt and maintain from 4 to 6 hours
Pour the dry mixture into a container with clean water at room temperature in the proportion of 0.18-0.21 l per 1 kg of the mixture (4.5-5.25 l per 25 kg bag). Mix thoroughly with a stirrer or a low-speed drill with a nozzle until a homogeneous consistency without lumps and clots. Then let the solution stand for 5 minutes and mix thoroughly again. The mortar retains its adhesive properties for 2 hour.
Attention! Do not add other components to the mixture.
Execution of work.
Apply the prepared mortar mixture with a spatula or trowel to the surface. Then level it with a notched comb or a spatula with a U-shaped or square-shaped teeth, which form even ridges of the same height on the surface (the spatula must be held at an angle of 45 ° to the surface). After laying the tiles, remove any adhesive residues with a damp sponge. The width of the tile joints must be at least 2 mm.
Do not pre-soak the tiles.
When facing with slabs that have a thickness of more than 10 mm and dimensions of more than 400×400 mm, work should be performed using a combined application method: apply the adhesive solution to the base with a layer the size of a spatula’s notch, as well as on the back of the facing tile with a thickness of about 1-2 mm , and for wall structures – with additional mechanical attachment to structures.
The shelf life of the mortar mixture is 2 hours. The tiles must be installed no later than 25 minutes after the application of the adhesive solution. Adjust the tiles within 20 minutes after laying. Grouting should be started no earlier than 24 hours after laying the tiles.
Work should be performed at temperatures from +5 ° C to +30 ° C. The most effective result is achieved at a temperature of +20 ° C and a relative humidity of 60%. In other conditions, the operating parameters of the mixture may change.
When performing work, the facade must be protected from direct sunlight, as well as high humidity (rain, fog, etc.).
On average, it is consumed from 2.6 kg / m2, depending on the thickness of the applied layer and the condition of the surface.
The mixture contains cement, which causes an alkaline reaction at the moment of hydration, therefore, when working, it is necessary to protect eyes and skin. In case of contact with eyes, rinse immediately with running water and consult a doctor.
The mixture must be stored in original sealed packaging in a dry place on pallets. The shelf life is 12 months from the date of production indicated on the package. Use damaged bags first.
Packaging. 25 kg paper bags with an inner polyethylene layer.
