Grassroots treatment→stretching→pre-laying→paving→pointing→cleaning
Construction Technology:
Before laying, molds should be made to select bricks, and tiles with large size deviations that meet the requirements are selected and used at the corners or non-whole bricks.
(1) Grass-roots treatment: Thoroughly clean up the dust and debris, and there must be no defects such as hollowing, cracking and sanding.
(2) Spring line: Before construction, pop up the elevation control line around the wall, and pop up the cross line on the ground to control the separation size of the floor tiles.
(3) Pre-paving: First, on the basis of the design requirements of the drawings, strictly select the color, texture, and surface smoothness of the floor tiles, and then pre-pave according to the requirements of the drawings. Adjust and exchange the size, color, and texture errors that may occur in the pre-paving until the best effect is achieved, and they are stacked neatly and neatly according to the paving.
(4) Paving: 1:3 dry hard cement mortar is used for paving, and the thickness of the mortar is about 25mm. Wet the back of the floor tiles before laying, and it is advisable to dry the front. Put the floor tiles on the cement mortar according to the requirements, and lightly tap the surface of the floor tiles with a rubber hammer until it is dense and flat to meet the requirements.
(5) Pointing: Clean up the joints 24 hours after the floor tiles are laid. Before jointing, the impurities in the gaps of the floor tiles should be wiped clean, and joints should be jointed with a special sealant.
(6) Cleaning: During the construction process, it should be cleaned as soon as it is dry. After the completion (generally after 24 hours), clean the surface of the floor tiles with cotton yarn and other materials.
The quality of floor tile laying:
The surface of the floor tiles is clean, the pattern is clear, the color is consistent, the joints are uniform, the periphery is straight, the pointing joints are smooth and smooth, and the plates have no cracks, corner drop and lack of corrugation.
Floor tile laying:
1: The tiles should be soaked in water for half a day before use, subject to the fact that the tiles do not bubble.
2: The kitchen and bathroom should have a slope of running water, no water accumulation, and no backflow of water. If the original waterproof layer is damaged during construction, waterproof treatment must be done, and there is no leakage in the 12-hour test of accumulated water.
3: After the floor tiles are laid, cover the brick surface with cardboard, etc., and walk on the brick surface at least 24 hours later.
Laying of wall tiles:
1: When treating the base, all kinds of dirt on the wall should be cleaned up, and watered and moistened one day in advance. If the base is a new wall, when the cement mortar is 70% dry, it should carry out brick arrangement, spring line, and sticky towel wall brick.
2: The tiles must be soaked in clean water for more than 2 hours before pasting, subject to the fact that the tiles do not bubble, take them out and dry them for later use.
3: When laying and sticking, when encountering pipelines, light switches, and supports for toilet equipment, etc., they must be cut and matched with whole brick sets, and it is forbidden to use non-whole bricks to piece together and paste.
