First, construction preparation
1. Material
(1) Cement: Ordinary portland cement or slag portland cement No. 325.
(2) White cement: No. 325 white cement (for scratching).
(3) Sand.
(4) Lime paste: When used, the mortar should not contain uncured particles and impurities. (If lime powder is used, it should be soaked thoroughly one week in advance.
(5) ceramics, glass mosaic tiles (mosaic): varieties, specifications, color according to design requirements, and should have product certification.
2, operating conditions
(1) Finishing of the plastering of the ceiling and wall pillars.
(2) Wall column concealed pipelines, electrical boxes and doors and windows have been installed and passed inspection.
(3) The gap between the installed sill plate, door and window frame and wall column shall be filled with 1:2.5 cement mortar (the aluminum door and window edge shall be determined by design); the aluminum door and window cabinet shall be pasted with protective film.
(4) Wall cylinder surface clean (without oil, laitance, residual ash, etc.), affecting the wall surface of the mosaic tile protruding from the mosaic tile (Masek) shall be flattened, and the excessively concave wall surface shall be applied with 1:2.5 cement mortar. Layer pressure leveling. (Moisture before plastering).
Second, the process
Grass-roots processing → ash cake, making ribs → wet base → smearing mortar → smear layer mortar → pre-arrangement grid line → tiling → wetted paper → uncovering paper → seam cleaning → sew cleaning
Third, the operating process
(1) When the base is a concrete wall cylinder:
For the smooth surface layer, the hair should be first brushed and brushed with a wire brush and then wetted with water. Bases with a very smooth surface should be "gapped". The surface is dusty, the dirt is clean, the watering is wet, use 1:1 cement fine mortar, spray or use a brush to shake the mortar to the smooth base surface. The throwing point should be even, after the final coagulation and then watering conservation, until the cement mortar has a higher strength, and the hand will not move.
(2) Brick wall base: watering one day ahead
1) Wipe the base ash:
Hang vertically, find rules, apply ash cakes, punch. When suspending the vertical and looking for the rules, the symmetry of the arrangement of bricks, such as the window sill, the waist line, and the vertical corner of the wall, etc., as well as the indoor floor tile, should be considered as the overall perfection.
2) Wet the base layer with water (the concrete base layer is evenly coated with a 0.5 g cement paste with a cement ratio of 0.5), and use a 1:2.5 cement mortar to clean the base ash (also use 1:0.5: (4 cement lime mortar), the first layer should be 5mm thick, with iron trowel, even pressure compaction; until the first layer is dry to seven to eighty percent after the second layer can be wiped, the thickness of about 8 ~ 10mm, until Crushing ribs are as large as they are, flattened with a pressure ruler, and then compacted with a wooden trowel and rammed into a mat. After the foundation ash was wiped off, the water was cured after final coagulation according to the temperature conditions.
(3) pre-patch mosaic tiles (mosaic), bombs. According to the requirements of the design drawings, a room and a whole wall of cylindrical pillars are affixed to the bricks of the same classification. The arrangement of bricks shall start at the inside corner and stop at Yangjiao (taken away); start from the ceiling and stop at the ground. ); parapet wall, window tops, ledges and various waist line parts, the top bricks should be covered with facade bricks to prevent seepage, causing empty drums; if there is no drip line design, the facade of various types of waistline front brick The block should protrude about 3mm, and the brick at the bottom of the line should be about 3~5mm from the inner wing to facilitate drip. Lines of pattern variation and vertical and horizontal lines of control are arranged. The vertical control line spacing is generally set to one degree with the width of five bricks, and the horizontal control line is usually set at one degree with the width of three bricks. Wall skirts and baseboards should have their height control lines ejected.
(4) Veneer.
1) hard bottom tile method:
a. After the final coagulation of the base ash is completed (usually every other day), re-watering and moistening, apply the cement paste to the tiling, and use a wooden trowel to apply the cement paste to a uniform thickness (approximate thickness of 1 to 2 mm). .
b. Brush the water with a brush to wipe off the dust on the surface of the brick. Fill the white cement paste with an iron trowel to fill the seams of the mosaic tile (mixture of fine sand and white cement into a slurry) , and then paste the wall. When sticking, you should pay attention to the pattern between patterns, but also make mistakes. After the bricks are affixed, apply iron trowels to compact them to make them stick and correct.
c. After the mosaic tile (mosaic) is firmly affixed (about 30 minutes later), wipe the water with a brush and wipe the paper surface to remove the paper.
d. Check whether the size of the seam is uniform and smooth. Correct the skew and width of the seam in time. The sewing sequence should be carried out horizontally and vertically first.
2) soft bottom tile method:
a. When the base ash is applied, about 8 to 10 mm thick is left as a wet ash layer.
b. Moisten the bottom ash surface and moisten the ground ash according to the rushing ribs (according to the area where the shift can be tiled). Use a pressure ruler to scrape the surface and compact it with a wooden trowel.
c. Wait until the ash surface is dry to about 80%. Paving is done according to the hard bottom method. The soft floor laying method is generally applicable to the construction of a large area of ​​the outer wall. Its feature is that it is beneficial to the flatness control.
(5) Squeezing:
After cleaning and uncovering the paper, the remaining paper and the cement that has been squeezed out of the joint (can be scrubbed with water and brushed properly). Fill the seams with white cement and clean the tiles with cotton or cloth until no residue is left.
