One. Are polished bricks prone to blistering?
Using cement to adhere glazed tiles to walls can easily lead to air pockets and detachment. The reasons for this include: the tiles' high water absorption rate affecting the adhesion, the tiles' high density affecting the adhesion, and the presence of anti-fouling agents on the tiles at the time of manufacture affecting the adhesion.
Polished tiles develop air pockets due to the presence of gaps between the polished tiles and the cement used for installation. This results in insufficient contact between the polished tiles and the walls or floors, leading to loss of support and load-bearing capacity, which can cause air pockets, detachment, and cracking.
Two. Methods for repairing hollowed bricks
1、For hollowed-out corners and edges on polished bricks,You can use a small trowel to knock open the gaps between the trowel bricks, then pour the trowel brick adhesive into the gaps. The air pockets will automatically absorb the adhesive until it is completely filled and set, which avoids the need for a complete replacement. This can be done without a professional; you can easily complete the task yourself.
2、For small areas of expansion in polished tiles,You can thoroughly clean the brick joints, saturate the floor with water, apply a cement slurry to the adhesive, and gently strike with a rubber mallet to allow the cement slurry to penetrate. once the cement slurry has penetrated, apply weight to dry it, and this process can be done manually.
3. If there is a large area of hollowed-out tiles,"It is only possible to remove and reinstall all polished tiles using a glass suction cup. The existing concrete floor must be roughened, and a new substrate must be prepared before the polished tiles are reinstalled."
4、Wall tiles are developing voids.、detachmentPhenomenonIf the affected area impacts functionality and aesthetics, it can be removed and the substrate cleaned before re-applying the tiles. If there are air pockets in the corners, it is not necessary to address them, as they do not affect the functionality or appearance.
