Consumable indicators
To prepare an adhesive solution, you need to calculate its volume depending on the area of the facing work and the capabilities of a specialist. On average, the consumption of dry mix per tile is from 2.5 to 5 kg per 1 m2, depending on its size. The larger the size of the facing material, the more mortar is consumed. This is because heavy tiles require a thicker adhesive.
You can focus on the following proportions of consumption, depending on the shape of the tile and the size of the teeth of the working trowel. For tiles from:
- 100x100 to 150x150 mm - 2.5 kg / m2 with a 6 mm spatula;
- 150x200 to 250x250 mm - 3 kg / m2 with a 6-8 mm spatula;
- 250x330 to 330x330 mm - 3.5-4 kg / m2 with a spatula 8-10 mm;
- 300x450 to 450x450 mm - 5 kg / m2 with a 10-15 mm spatula.
For other heavy cladding materials and conditions of high load on the coverings (eg floors), the consumption of the adhesive mass increases. In this case, an adhesive layer is applied to the base and the back of the facing material.
What kind of work is it suitable for?
The scope of K80 is not limited to laying clinker or ceramic tiles. It is successfully used for laying finishing materials from natural and artificial stone, marble, mosaic glass, porcelain stoneware. The glue can be used for finishing work in various premises (from stairwells to the fireplace hall of the house).
It can be based on:
- concrete, aerated concrete and brick surfaces;
- fixed cement screeds;
- floating cement screeds;
- plaster based on cement or a mixture of cement and sand;
- gypsum plaster or gypsum panels;
- drywall sheets;
- old tile covering (wall or floor).
In addition to finishing walls and floor coverings in rooms, this substance is also used for outdoor work. The adhesive is suitable for cladding:
- terraces;
- steps;
- balconies;
- facades.
The layer of adhesive for fastening or leveling can be up to 15 mm without loss of fastener quality and no deformation due to drying of the layer.
Consumable indicators
The consumption of glue when laying tiles depends on:
- The properties of the facing material - the size, texture and porosity of the tiles.
- Techniques for applying glue, thickness of the glue layer.
- The properties of the base - the presence of irregularities on the surfaces, which requires filling.
Based on these parameters, it is necessary to calculate how much of the finished mixture is needed. per 1 square meter and, accordingly, the entire coverage area. Considering that the assortment of Litokol glue mixtures is quite wide, consider the average consumption of glue by type of composition.
Cement adhesive: with a thickness of 1 mm, an average of about 1.3 kg is consumed per square meter of base
REFERENCE: some articles are more expensive (for example, BETONKOL K9)
- Dispersion adhesive: a layer of 1 mm thick for an area of 1 square meter consumes approximately 2.5 kg of adhesive
- Reactive glue: an average of 2.5 kg of ready-mixed mixture is needed per 1 square meter of the base
- Elastic tile adhesive: 1.3 kg per 1 square meter
Expenditure indicators are rather arbitrary and the final result depends on all factors influencing it. For ease of calculating the consumption of the Litokol mixture, there are special calculators.
By specifying individual parameters, you can independently estimate the required volume of consumables.
Specifications
The full name of the tile adhesive is: Litokol Litoflex K80 white. On sale it is a dry mix in standard 25 kg bags. Refers to elastic cement group adhesives. Possessing a high holding capacity (adhesion), the substance ensures reliable fastening of the facing material to any base.
The ductility of the adhesive does not allow the facing material to come off even under conditions of stress between it and the base as a result of deformations from temperature or changes in the structure of interacting materials. That is why Litokol K80 is often used for flooring and wall cladding in public places with high loads:
- corridors of medical institutions;
- offices;
- shopping and business centers;
- train stations and airports;
- sports facilities.
This adhesive solution is considered moisture resistant. It is not destroyed by the action of water in bathrooms, showers and bathrooms, basements and industrial premises with high humidity. The possibility of finishing buildings from the outside using K80 proves the frost resistance of its composition. The positive characteristics of the adhesive material include the following features:
- the readiness time of the adhesive solution after mixing with water is 5 minutes;
- the lifetime of the finished glue without loss of quality does not exceed 8 hours;
- the possibility of correcting already glued facing materials is no more than 30 minutes;
- readiness of the lined layer for grouting - after 7 hours on a vertical base and after 24 hours - on the floor;
- air temperature when working with a solution - not lower than +5 and not higher than +35 degrees;
- operating temperature of lined surfaces: from -30 to +90 degrees C;
- environmental safety of the glue (no asbestos).
This glue is one of the best in terms of ease of use and durability of coatings. It is not for nothing that it is very popular among the population and is highly appreciated by the masters in the field of construction and repair. And the price is affordable.
Work algorithm
Litoflex K80 dry mixture is diluted in clean water at a temperature of 18-22 degrees at the rate of 4 kg of the mixture to 1 liter of water. The whole bag (25 kg) is diluted in 6-6.5 liters of water. Pour the powder into water in parts and stir thoroughly until a homogeneous pasty mass without lumps. After that, the solution should be infused for 5-7 minutes, after which it is thoroughly stirred again. Then you can get to work.
Mounting
The base for the cladding is prepared in advance. It must be flat, dry, clean and sturdy. In cases of special hygroscopicity, the base must be treated with mastic. If cladding is made on an old tile floor, you need to wash the coating with warm water and baking soda. All this is done in advance, and not after diluting the glue. The base must be prepared one day before work.
Next, you need to prepare the tile, clean its back side from dirt and dust. It is not necessary to soak the tiles in advance, unlike laying tiles on cement mortar. You will need a spatula of the correct size. In addition to the size of the comb, it should have a width that will cover up to 70% of the tile surface in one application when working indoors.
First, the adhesive solution is applied to the base with the smooth side of the spatula in an even layer of small thickness. Then immediately - a layer with a spatula comb. It is better to apply the solution not for each tile separately, but on an area that can be tiled in 15-20 minutes. In this case, there will be a margin of time to adjust your work. Tile is attached to a layer of glue with pressure, if necessary, it is leveled using a level or markers.
The tile is laid by the suture method to avoid breakage during thermal and shrinkage deformation. The freshly tiled surface should not come into contact with water for 24 hours. It should not be exposed to frost or direct sunlight for a week. You can grind the seams 7-8 hours after the base is tiled (in a day - on the floor).
