How to make holes in the wall to avoid dust scattering

When drilling walls, the way of dust is quite difficult. To make matters worse, if you inhale dust while drilling into a wall, it will affect your health. So, if you're a wall driller or doing wall drilling for the first time, here are some simple ways to do it:

1. Use pieces of paper.

Glue a piece of paper folded like a V-shaped piece of paper under the drilled hole in the wall (pictured below). You need to put the piece of paper on the edge with glue. Then glue the edge of the glue underneath the wall surface to drill into the wall. Therefore, when drilling the wall, there is a tool that prevents the dust from falling.

2. Use plastic cups.

The use of cups is considered to be an easy and fast and effective way to drill holes in dust-free walls. drill walls with plastic or paper cups; You just need to prepare a plastic or paper cup (medium capacity) and drill holes.

The guide on how to drill a dust-free wall with a paper or plastic cup is very easy to follow. You only need to drill a main hole in the middle of the bottom of the cup. Next, adjust the position of the drill hole so that the hole in the wall is in the center of the rim.

Hold the rim close to the wall and drill the hole. Any dust, no matter how small, will lie in the cup and not fall.

3. Use a water-soaked rag.

It's also a trick to drill into the wall, no dust is simple and quite fast. You just need to use a rag, soaked in water, and place it underneath the location of the wall drill. When drilling, dust falls onto the rag, helping to prevent dust from falling into the air.

After drilling into the wall, gently grasp the rag and clean it from the bottom up.

You can use A4 paper to fold into a long box and place it under the percussion drill, which can store the scattered dust well, and you can also put a protective cover such as a plastic bag under the drill bit, and use a vacuum cleaner to vacuum after punching holes in the wall, so that the dust will not be scattered.

1. Hold the drill bit of the drilling machine with your right hand.

2. Put the dust bag on the drill bit.

3. Load the drill bit with the dust bag on the drilling rig.

4. Pull up the dust bag and aim the drill bit at the position of the hole.

5. Let go of the dust bag and start drilling, at this time the dust bag will collect the dust under the drilling.

If you use a vacuum cleaner, there will be no dust at all. I see that Shanghai Shangsi brand stainless steel cabinet installation wall cabinets are all such dust-free installation.

Modern people pay more attention to the layering of space, and no longer want to leave blank space for the ceiling of the new house, and generally ask Yu Zheng Li carpenter Cong Shufu to design his favorite ceiling type to make the ceiling look more beautiful. Before the ceiling is installed, it is necessary to punch holes in the ceiling, so how to punch holes in the ceiling? What should we pay attention to?

Let's take a look at the punching techniques.

1. Ceiling punching skills.

The traditional punching method needs to climb to the ladder to operate, so there will be certain safety hazards to the construction personnel, and the long-term operation will make people inhale a lot of dust and cause injury to the body. You can directly use the new punching tool, first prepare the boom, buckle and punching nails, fix them together, put them in the punching tool, and punch the position of the ceiling punch, with this way of construction, no need to climb the ceiling, and will not worry about dust flying all over the sky, so that the efficiency is greatly improved.

2. Precautions for traditional ceiling punching methods.

1. Install the drill nib on the percussion drill first, and the drill nib model is recommended to be below 14 mm to prevent it from penetrating the ceiling or waterproof layer.

2. If you use the traditional punching mode, you need to use a herringbone ladder. Because the floor height of commercial housing is generally 3 meters, and the height of the ladder is the height of the floor - the height of the builder.

3. Before punching, it is recommended to use a metal detector to look at the ceiling punching area, see if there are steel bars inside, or embedded wires, and mark if there are any.

4. If you drill in the traditional way, the dust will drift directly to the eyes or face. So be sure to bring a dust cover and goggles.

5. In the process of drilling, it is necessary to pay attention to keeping the percussion drill and the ceiling vertical, and use appropriate strength to top up. When drilling about 2 5 cm, if you suddenly feel the vibration become larger, or the drilling speed suddenly decreases or stops, this situation should be stopped immediately, and it is very likely that the steel bar will be reached.
