Twenty common sense of tile laying (Part II)

- Jun 15, 2018 -


Tile cutting is also a link that is prone to problems. Cutting dimensions and cutting methods all require precise operation. If the craftsmanship is not superb, cutting the tiles by hand may cause cracks in the surface of the tiles. If more cutting operations (complex paving schemes or parquet) are required, professional equipment is recommended for processing.


12.Cement mortar proportion

The key to cement mortar adhesion lies in the ratio of cement and sand. The paving master suggested that 1:3 cement mortar can be used for paving tiles, and the mortar should not be too thin; the wall tiles can be used in a ratio of 1:2 or 1:1, and the ground leveling can use 1:1 cement mortar, and pure Cement slurry.

13.Cement marking

Cement mortar markings indirectly affect its condensation effect with the tiles. If the label is too low, it will cause the tile to separate directly from the cement mortar, and the tiles will be empty. The label is too high and the tiles shrink significantly after the water evaporates. If the tiles cannot bear, they will be “cracked”.
According to the standard procurement of cement, it is generally recommended that the best use of tile 452 cement, that is, the number 32.5 cement.

14.Primary treatment

The basic ground wall treatment is a very important task. Before laying, the grass-roots level must be handled cleanly to ensure that all kinds of dirt and plaster are removed. It is best to wet the ground with the water the day before and the humidity is controlled at 30-70%.
In addition, whether the grass-roots level is smooth, whether the new wall surface has empty drum cracks, whether the waterproof layer is delaminated, etc., are all attention to detail.

15.Attention to sand

Sand and rubble often appear on the construction site, and scratches can easily be left on the tiles if you accidentally rub on your feet. Therefore, the construction site must pay attention to the protection of the tiles, and the paved tiles can be placed on the paperboard first, and at the same time avoid dragging heavy construction equipment on the tiles.


Spaces such as bathrooms and balconies must be waterproof before tiling. If the original waterproof layer is damaged during construction, it must be re-waterproofed, and ensure that there is no leakage of the accumulated water for 24 hours.

17.Clean the sticky dirt in time

After laying for 1 hour, the cement, caulking agent or other sticky objects left on the brick surface should be wiped off in time, because it is difficult to clean after four hours like the caulking agent.

18.Check the paving effect

After paving for 12 hours, the effect of laying tiles (empty drum rate, cracks, etc.) should be checked in due time. If it is found to be unqualified, it should be re-layed.

19.Tile punching

The location of the hole is best to choose two tiles joints, if not appropriate, can be in the middle of the tile, it is best not to choose the edge of the tile, easy to break bricks.
In addition, check whether there is empty drum at the tile before punching. If you have empty drum, you need to re-position, because the empty hole at the hole can easily cause the tile to break off.

20.Size of the hole

The incision on the outlet of the wall must be suitable, otherwise it will open too much to expose the pores. The circle is circular and it is not ugly to cut square holes.
