The kitchen flue is tiled, and the sun corner is cracked diagonally

This situation is generally that the caulk and the cement inside can not stick together, that is to say, there is a hollow drum phenomenon in the paste, and the crack is not serious.

Knock down the tiles next to the flue with your hands to see if there is a hollow drum phenomenon, if there is a knock down and repaste, if not, it will be fine, just a problem of caulk, just get some caulk and fill it yourself. Besides, this is normal, so there's no need to worry.

I don't know how big the gap is? If it's smaller, it's good to fill it up with caulk.

If it is relatively large, it means that there is no iron fast, and it needs to be re-paved.

Generally speaking, the seams are not filled, and as long as the other positions are not empty, they will not fall off.

1. Tile paving hollow drum delamination.

Tile hollowing leads to tile cracking is the most common construction quality problem in the current decoration, due to the inconsistency of the cement mortar layer on the tile at the hollow drum part and the non-hollow drum part, resulting in tile cracking. The original hollowing of ceramic tile paving includes: the brushing layer of the base layer delamination hollowing, the poor curing strength of the brushing layer, the wall surface is not sprinkled with water and moistened before the cement mortar is paved, the cement mortar applied at the bottom of the tile embryo is not full and uniform, the tile seam is too narrow, and the tile is not dried and solidified.

2. The bottom embryo is polished and chamfered too thin when the tile at the sunny corner is treated as a corner.

The back side is inverted at a 45° angle and is too thin, which destroys the embryo glaze bonding layer and reduces its crack resistance and flexural strength. Most of the cracks caused by this condition occur in the joints of the tiles.

Treatment method of tile cracking at the flue:

1. If the tile cracks appear in the middle of the brick surface or the wall is unevenly distributed, the cracked tiles need to be removed for maintenance, and the base layer is cleaned up and the tiles are re-pasted.

2. If there is cracking in the chamfering part of the tile at the joint of the yang corner, you can paste the metal buckle with an L-shaped cross-section at the yang corner, and its materials are common aluminum alloy and stainless steel. The stainless steel yangjiao buckle can be purchased as a finished product, or you can directly find a stainless steel processing store for processing.
