One. Reasons for air pockets in floor tiles.
There are many reasons for air pockets in tiled floors, but they are commonly caused by improper construction. These include:- Using too much water in the cement mortar during installation.- Using cement mortar that has already dried.- Failing to remove contaminants from the back of the tiles.
Two, Methods for handling air pockets in tiled surfaces.
1、Substrate Preparation: Remove dust and oil stains from the surface.
2. Determine the application point: Typically, an application point is established at a distance of 20-750px. The application point can be located in areas with wider gaps or more open spaces, and should be pre-marked.
3、Seal Cracks: Apply quick-drying sealant along the crack surface, leaving an opening for injection.
4、Install plastic base: Apply sealant to adhere the base to the inlet opening.
5、Install the injection pump: After the sealant has fully cured, pour the prepared injection resin into the injection pump and tighten the pump, which contains the resin, onto the base.
6. Grouting: Release the spring on the grouting pump, confirm that the resin is being injected, and add more resin if necessary before continuing.
7、Final Filling: After the injection speed has decreased and no further injection is detected, the injection pump can be removed. Use a plug to seal the base.
8. After the resin has cured, remove the base and plug, and clean the surface with sealant.
Three. How to prevent tile voids
The best way to prevent tile expansion is to inspect the tiles after installation. If defects are found during acceptance, the contractor should promptly address them.There are several easy methods for inspecting tiles:* Use a rubber hammer to tap each tile on the ground.* Listen to the sound produced by tapping the tiles. If the sound is dull, it indicates that the tiles are securely installed.* If you hear a clear "thud, thud" sound, it indicates that the tiles are not properly installed and may have expansion issues.
