LAYING RECOMMENDATIONS FOR CERAMIC TILES


BASEMENT

Correct ceramic tiles laying requires an accurate basement preparation. First of all, you should examine carefully the general condition of the surface on which is supposed to apply the adhesive, as well as consider its characteristics such as static, integrity, texture, strain capacity and water absorption. The basement should be dry and smooth as possible, free from all dirt, dust, oil or grease. Besides, it is important that it is completely hardened after a preliminary preparation and coating with special leveling compounds. Then the surface is capable of withstanding the load required, possible pressure and structural fluctuations which in the operation may adversely affect the condition of tiles.

LAYING

When laying tiles, adhesive solution on the basis of cement or synthetic resin, which is applied in a thin layer, is typically used. Experts do not recommend applying a thick layer of the mixture, since due to its low water absorption, they do not provide a strong coupling of the tiles with the basement surface.

 

Basic requirements for laying

The most frequently, when laying tiles, in particular when laying wall tiles on the nonstandard surfaces, adhesive solution prepared on the basis of cement C2 are used. The maximum layer thickness should be 5-10 mm. For homogeneity of the mixture it should be applied with a notched trowel. With this, the adhesive solution should not dry before laying the tiles, and is not recommended to dampen the tiles with water.

 

Environmental conditions at laying

When laying ceramic tile, the ambient temperature, as well as surface and the materials used temperature should range from +5 to +30 ? C. When laying external wall tiles facing, you should avoid high humidity, and wind speed shouldn’t exceed 50 km /h.

 

Adhesive preparation

 

Adhesive solutions on the cement base should be prepared according to the manufacturer's instructions in a special container with water using a mixer running at low speed. As a result, you should obtain a creamy homogeneous mass without lumps. The mass obtained should be used within terms specified by the manufacturer, after that is not possible to stir it with the water again and use it again. The quantity of the solution prepared depends directly on the laying speed and environmental conditions.

 

Adhesive solution on synthetic resin are mixed according to the manufacturer's instructions with strict adherence to these proportions. To obtain a homogeneous mass, a thorough mixing is required, for which is preferably to apply a mixer with a screw mechanism. Temperatures at laying should correspond to +10 +25 ? C.

 

Adhesive application

When selecting a spatula for the application of the solution should be taken into account characteristics such as surface irregularities, type of laying, type of adhesive mixture, size of tiles. The required amount of solution is applied with spatula and spread evenly over the base, at that you need to make sure that the glue does not harden. Ceramic tile is laying on it and pressed tightly to ensure tight surfaces contact and avoid the formation of voids. You can use special rubber hammers.

 

Ceramic tiles laying

Before proceeding to laying, remove the tiles from different boxes and put them on an area of ??about 8-10 m ², in order to assess compliance of the required size and tone. The joints should be smooth, and their width depends on the format of the tiles, there functional use and expected loads. Is not recommended to make a laying stacking without joints, as well as make them less than 1.5 mm, thus, any excess of glue is removed immediately, before it hardens.

Periodically, you can take the tile off with applied adhesive solution to ensure uniformity of its application. When laying tiles of a rectangular firm, you should press first their longest side. Being finished the laying; the recommended indoor temperature should be observed. You also need to ensure a careful use of all the tools and materials so as not to damage the tiles, and provide them with maximum protection until the laying works will be finished.

JOINTS 

Structural joints

The joints must be filled evenly around the perimeter, and elasticity should not be less than 15%.

Expansion joints

For interiors such joints are used every 40 m², meanwhile for external premises - every 25 m². Their thickness depends on the expecting deformation.

GROUTING 

Seams should be floated 24 hours after completion of the installation of ceramic tiles. During grouting, you should follow the recommendations of the manufacturer specified in the instructions. The solution is applied with a suitable rubber spatula with diagonal movements, making sure the entire depth of the joint filling.

MAINTENANCE AND PREOPERATIONAL PHASE

The final stage of the ceramic tiles laying is a scrupulous and gentle cleaning of the tiled surface of excess cement, grout solution, dirt, etc. For this purpose, special solvents that need to be slightly diluted with water are used. At the same time in any case cannot be applied detergents on acid basis. Before using any chemical solutions, you need to moisten the surface to avoid possible absorption of grout materials. It is worth remembering that the cleaners cannot be used on the newly laid tiles, in order chemicals do not engage with the not hardened adhesive and grout. In the future, you should follow the recommendations for keeping tiled surface clean and rules of maintenance.
