What parameters are important when installing tile? Surface to be oblitsevat tiles can vary in terms of materials, construction solutions, the size and technical limitations. When laying the floor normally used reinforced concrete or precast slabs, mixed cement and tile floors, cement and metal ceilings. Walls can be made of grubokeramicheskih materials, from cement or concrete blocks, or constitute a prefabricated cement-wood paneling, concrete panels, gypsum board or gypsum blocks from the solution. That is the nature of the structure to be are faced with ceramic tiles, depends on the design and technical solution to the work. In studying the work surfaces should pay attention to several important aspects: the surface state. Based on the analysis of surfaces at the design stage a decision on applying the leveling layer. Needs careful handling and cleaning of surfaces with the removal of irregularities. In addition, prior to the masonry surface must be treated with a special compound that protects the foundation from moisture and improves the adhesion of glue. On surface condition and the choice may depend on the binder composition. The effect of expansion and sizing material at the stage of maturation. This effect must be considered in relation to any type of material, especially in the case of tiling a large area, in areas with large temperature gradients and the concrete foundation. Modulus. Mechanical characteristics of structures determine the behavior of structures under load with the possibility of deformation due to vibration or the effort. In the design should provide for the possible deformations. The structural composition and articulation. For all types of structures are present joints between parts, where the slight frequency shift relative to each other. This structural joints that are performed during construction using trusses or panels. Can also be carried out expansion joints, shrinkable joints and flexible joints, which must compensate the deformation of the structure and shrinkage as a result of maturation of the cement. Necessary to accurately determine the location, direction and dimensions of joints, as these affect the joints and masonry. The geometry of the cladding surface. The shape of the surface affects the choice of tile dimensions, their location and technique of masonry. The size of the surface may determine the need for the expansion joints. Leveling a tile floor screeds When aligning floors may need to lower their level, or conversely, to raise. First performed dismantling of part or all available under the layers. The second production is realized ties .. If it is covered with linoleum or PVC tiles, they will have to be removed. If the floor just laid on the floor, then raised plinth that held him, and he rolled linoleum. If it is glued, then trowel poddevayut edge of the sheet and gently tear off. Then, using kardschetki or a large sandpaper remove adhesive residue. Prepare the surface to the top of the work, you need to take care of ceramic tile. For better adhesion of tiles with a solution before starting work, they should be soaked for a while in the water so that their surface was under water. Sometimes under the enamel of some varieties of ceramic tiles in a rich wetting them with water may remain watery spot. These tiles should not soak them with the inside of the need to wet a wet brush. Better yet, before laying a tile on its back side to cause a little thinned grout and then clean off the edge of his trowel in order to avoid a sharp redistribution of moisture, and after laying the tile in place is not anymore. If possible, the veneer ceramic tile to start with sex, as in this case, the tiles laid on the wall, will be based on laid horizontally on level floors. If the wall is necessary to issue before the floors, the bottom of each wall will have to install the rail, which will build the lower rows of tiles. Srubanie mounds are done by the hammer (pneumatic) and a chisel, you can apply a punch to the shoulder blade. Also cut down oily areas screed. If the level must be reduced greatly, then removed all the layers to the ground. Wooden floors dealt with crowbar. The resulting removal of potholes are buried sand-cement mortar. Gidroizolyatsiyapolov Before you tie in the wet pomeschniyah necessary to make waterproofing. It can be done from the roofing material or special mixtures that are sold in stores. If waterproofing is needed only to prevent leaks in the manufacture of ties, the suit thick polyethylene or asphalt. Roofing material, polyethylene or asphalt they spread on the floor of the factory on the edge of the wall. The height of the edges of the wall must not exceed the floor level by 15 centimeters. In the corners of the material folds neatly. In waterproofing shall have no openings. If you do not have one piece, then a panel stacked with a lap of 20 inches. If waterproofing is a long-term, then using the rubber-asphalt mastic the joints are glued panels and adjacency to the walls. Performing screed Screed done when necessary to align the floor surface with large roughness, remove, or make the slope of the floor, or raise his level. Thickness at least 15 mm screed applied polymer solution, which is kneaded with cement and sand (1:3) on PVA emulsion diluted 1:4 with water. If the requirements for surface ties are very strict, it can be made in two steps. First, the usual screed to level at 3-5 mm below the required level, then a layer of self-leveling Floor Levelling Screed usual screed is made of cement-sand mortar at a ratio of 1:3. Before placing the solution surface underlayment moisturize to prevent excessive suction of moisture from the mortar. In larger rooms, the solution is placed between two strips lighthouse lane through one. In a small room is filled once the entire surface. Solution is spread flat rack or rule, which is based on two rails of Lighthouse. In large rooms flooded with bands give the freeze, remove the rack and fill prodolzhabt using as a beacon edge stacked strips. At low humidity freshly laid screed protect from moisture loss before acquiring the necessary strength solution. To do this, it is covered with matting and watered. After solidification of the solution plane is checked again, and if necessary remove the minor defects. Top ties can produce additional waterproofing. Average consumption of cement on the thickness of 1 mm screed on 1 square meter - 500 grams of sand - 1.5 kg, and PVA - 100 grams.
