Some people say that trouble begins when you get the key to a new house, and the decoration process is a "receiving" process. Indeed, decoration is a very complex and tedious matter, in which problems of all sizes will inevitably be encountered. The issue that Mr. Tao wants to talk about today is related to "punching".
Usually, air conditioning installation holes, bathroom water heater pipe openings, kitchen range hood pipe holes and other holes will be planned in advance when people decorate their houses, and the space, location, quantity and size will be reserved. The tiling master will also use these holes according to these Planning, cutting and drilling the tiles before laying. Although it has always been emphasized that drilling must be planned in advance, it is always difficult to prevent the situation from being missed after even calculation.
I believe that most homeowners have had a similar experience. After installing ceramic tiles throughout the house, they discovered that cabinets, bathroom cabinets, shelves, etc. still needed to be drilled when they came in. However, improper operation when drilling holes in already installed ceramic tiles can easily lead to chipping and contamination of the wall. Below are the steps and precautions for drilling holes in ceramic tiles compiled by Zhongtaojun. It is recommended to save them. Maybe you will use them one day.

Position selection
A wall tile cannot be drilled at any position. If the hole location is not selected correctly, a lot of trouble may occur. Therefore, before drilling holes, you must first confirm the appropriate drilling location. Professionals suggest that you should pay attention to the following two points:
1. Before drilling holes in the tiles, check whether the tiles at the punched location are firmly attached and whether they are hollow. The ceramic tiles must be glued tightly at the location where the holes are drilled. Once a hollow appears on the surface of the ceramic tiles, it will be easy to break the ceramic tiles when drilling.
2. Before drilling holes in the tiles, make sure there are water pipes inside the wall. The location of the holes must be staggered to the location of the water and electricity pipes to avoid damaging the water and electricity pipes hidden in the wall. The problem becomes even more troublesome if the buried water circuit is damaged and involves removing the tiles and re-repairing it..

Tool Selection
Nowadays, more and more home decorations are choosing floor tiles on the walls or all-ceramic wall tiles. Some characteristics of the ceramic tile itself determine that you cannot use an ordinary electric drill when drilling holes, but you must choose a special ceramic tile drill bit. Regarding how to choose a drill bit, professionals put forward three suggestions:
1. To drill holes in the ceramic tiles, the commonly used tool is an electric hammer. An electric hammer is an electric tool with a drill bit installed on the head. Note that you need to choose an adjustable-speed electric hammer here, which will be more convenient to operate. At the beginning, you need to use a low speed to polish the surface of the tiles, and then choose to speed up after drilling in, so that the tiles will not break easily.
2. When drilling holes in the ceramic tiles, the choice of drill bit is crucial. If the diameter of the hole that needs to be drilled is very small, for example, just to install expansion bolts or plastic expansion bolts, it is recommended to choose a special drill bit for ceramic tiles or a special glass drill bit. This kind of drill bit has very good adaptability to the surface of ceramic tiles, and there is almost no slippage when drilling, causing the surface of the ceramic tiles to chip or even crack.
3. When a larger hole diameter is required, it is recommended to choose a special hole opener for ceramic tiles. When you need to drill holes with a diameter of 20 mm or larger, you need to choose a special tile hole opener. The tile hole opener is a cutting type, which is different from ordinary drill bits. When operating, the hole opener uses the rotation of the hole opener to cut the surface, and then cuts a circular hole in the tile. This tool can ensure that the hole opening is relatively regular.

How to operate
Choose positiveAfter determining the correct location for drilling and the appropriate drill bit or hole opener, the next step is to get started. Because the electric hammer is used directly on the surface of the ceramic tile when drilling, mistakes may occur if you are not careful. Therefore, professionals recommend paying attention to the following four operating points:
1. The location must be precise. Before drilling, be sure to use a marker to draw the location of the hole. The drill bit must drill the tile along the hole location accurately and steadily. Because the ceramic tile is smooth and brittle, you can use a drill to grind out a depression first, or put a piece of tape on the ceramic tile to increase friction. This will ensure that the drill does not slip when drilling.
2. The angle should be vertical. When drilling, try to keep the drill bit at a 90-degree angle to the ceramic tile surface, and do not change the angle from drilling to completion. If the way you hold the drill is correct, the edge of the hole will be vertical and beautiful; but if you hold the drill crookedly, the hole will be very rough; if your gestures are different during the drilling process Changes can easily lead to chipping or chipping of ceramic tiles. In reality, most of the chipping problems of ceramic tiles when drilling holes are related to this.
3. The rhythm needs to be adjusted. Many people ignore the "hard and brittle" nature of ceramic tiles when drilling holes in ceramic tiles. They neither adjust the speed of the electric hammer nor consider the pressure and vibration of the electric hammer on the tiles. He drilled down hard and the tiles exploded. Based on the difference in hardness of ceramic tiles, you must operate at the lowest speed when drilling, and then slowly adjust the rhythm later. There are two advantages to doing this. One is that you can test the approximate hardness of the tiles, and the other is that you can polish the holes more accurately.
4. Spray water during the process. Before drilling holes in the tiles, prepare a water-jet tool if you are not using a rhinestone. This water spray tool is used to ensure that there is always water between the drill bit and the tile when drilling, which has a cooling effect. During the drilling process, water needs to be sprayed continuously, especially if the water is highly absorbent.For wall tiles, the temperature rise during drilling will cause the tiles to crack. It can be seen that spraying water is a very necessary step.

Remedy Tips
If you only learned the above nanny-style drilling tutorial with your eyes, but not with your hands, you will still overturn in the final practice. Then, Zhongtaojun will give you another very practical remedy tip learned from professionals - it can be summarized as "one stick", "two fillings" and "three coverings". It is said that it can effectively avoid "mom" See you beaten."
One stick:First clean up the tile debris, recycle the scraps of the same type of tiles at home, and cut them into suitable pieces. After sizing, use tile glue to stick to the broken area.
Second filling: Use caulking, plaster, paint or even toothpaste similar to the color of the tiles to fill the gaps. , sand it smooth after the filling solidifies.
Three coverings: If the damage on the surface of the ceramic tile is really unbearable to look at, it is recommended to use decorations. Or furniture blocks it. Sometimes, invisible = non-existent.
tip
Different ceramic tiles have different hardnesses, and the actual construction environment is even different. Therefore, what tools to use and what methods to adopt will depend on the specific situation.
The above sharing is the summed up experience of countless handicaps after drilling holes and breaking countless ceramic tiles.
