I believe you have seen a situation where ceramic tiles are made more often. The decorator will soak the tiles in water before laying them. At this time, everyone will have many questions about why they should soak the tiles in water? So, Should ceramic tiles be soaked in water before laying? With this question, let’s follow Zhongtao Jun to find out!
In fact, it is not difficult to find that in real life, ceramic tiles can be used in all aspects, whether it is in house decoration or in the appreciation of art, you can see them everywhere! ! !
1. The problem of water absorption of ceramic tiles
Water absorption is a physical quantity that indicates the extent to which an object absorbs water under normal atmospheric pressure. It is expressed as a percentage, which is the extent to which the ceramic tile absorbs water.
2. Is the lower the water absorption rate, the better?
Professionals remind that water absorption is a relative figure, not lower is better.
3. How to judge the water absorption rate?
The water absorption rate of ceramic tiles can be found in the "execution standards" according to the outer packaging instructions of the ceramic tiles or the certificate inside the box
4. The following are low water absorption ceramic tiles, and the implementation standards are
GB/T4100-2006 Appendix G
GB/T4100-2006 Appendix H
GB/T4100-2006 Appendix J
5. The following are high water absorption ceramic tiles, and the implementation standards are
GB/T4100-2006 Appendix K
GB/T4100-2006 Appendix L

6. The water absorption rate of ceramic tiles is related to the strength, wear resistance and gloss of ceramic tiles
Generally speaking, the lower the water absorption rate of ceramic tiles, the better the ceramic tiles, the higher the strength, the better the wear resistance and glossiness, and the products are less likely to crack or peel off. Ceramic tiles with high water absorption rates will cause cracks on the tile surface and peeling off of the entire tile after thermal expansion and contraction. You need to pay more attention to this problem especially when choosing tiles for bathroom tiles. But you must not blindly believe that the lower the water absorption rate of ceramic tiles, the better!
7. Should the tiles be soaked in water before being laid?
First of all, if you choose a new tile pasting material, that is, tile adhesive, you don’t need to use water bubbles when laying tiles. of. Tile adhesive is a glue-like substance. When laying tiles, apply it evenly to the back of the tiles and the wall to firmly bond the wall and tiles together. However, the back of the tiles must be cleaned before laying. After cleaning, proceed to paving.
Secondly, if you choose the traditional tiling method, that is, the cement mortar tiling method, the tiles need to be soaked in water. Posted later. If the tiles are laid without soaking in water, the pores on the back of the tiles will absorb a large amount of moisture in the cement mortar, causing the cement mortar to lose its binding force with the tiles, which may eventually lead to hollowing or falling off.
Of course, no matter which pasting method is used, the strength of the base layer must meet certain requirements. The method to test the strength is very simple. Use a sharp object to scratch the wall. If there are white marks on the surface, it means the strength is enough. If there are grooves on the wall, the strength is obviously unqualified.
After seeing this, you must have a certain understanding of the issue that Zhongtaojun shared with you today about Does ceramic tiles need to be soaked in water? I have something to do tomorrow and have a weekend! I wish you all a happy weekend in advance! That’s it for today’s sharing! Mr. Zhongtao will slip away first! O(∩_∩)O haha~
