I'm not used to it, so I can't do it.Many owners have this mentality: there are some construction practices that we can't understand, but I also know that it is the right thing to do, such as adding water to putty powder to mix. But there are still some constructions that we can't understand, but it feels weird
At this time, many people will come forward to stop it, thinking that the workers are not working according to the specifications. In fact, it is not necessary, these unbelievable construction steps are exactly the right way.
.01 Tiles soaked in water
I'm not used to it:Soak the tiles in a basin of water before construction, what is this for?Could it be the same as adding laundry detergent to cement and glue to putty powder, is it a worker's attempt to save trouble?
Facts:When buying ceramic tiles, you should have heard of "water absorption", which means that the back of the tile will absorb water. If the water absorption rate is too high, the tile will absorb the moisture in the cement mortar, resulting in a decrease in the viscosity of the cement mortar.
Therefore, it is necessary to soak the tiles in water first, so that the tiles can absorb enough water before pasting. There is no strict regulation on the soaking time, and it is generally advisable to "no longer bubble in the water". Some tiles have a water absorption rate of 0Below 5%, it will not bubble when you put it in, this kind of tile canDo not soak in water
.02 Dry powder paving
I'm not used to it:The cement and sand are not mixed into mortar with water, but are mixed and spread directly on the ground, and the tiles are put on after a simple sprinkling. This is obviously cutting corners, I remember that the tiles should be pasted like this
Facts:In the picture above, this kind of sticking is called "wet shop", and the kind of sticking that ordinary owners are not used to is called "dry shop". Dry laying has the benefits of dry laying, such as saving time, avoiding hollowing, and so on.
At present, dry paving and wet paving are mixed when tiling is pavedAll floors are dry-paved, fill it full, and avoid the hollow drum from breaking. All walls will be covered wet, the stickiness is greater and it avoids falling off.
.03 Wire turning
I'm not used to it:There are a lot of wires reserved in each junction box, and the wires are wound around the handle of the screwdriver, and they are wound in a circle. This is obviously trying to trick me into using more materials, so stop it quickly.
Facts:When it's time to repair the socket, you will know how important it is to reserve more wires in the wire box. Many times the wires cannot be removed and can only be cut. The length of the reservation often determines the number of times it can be repaired.
A long length of wire is reserved, and if it is stuffed directly into the wire box, it will cause the wire box to be very crowded. In the future, if you put a socket backplane in it, it is easy to get dangerous. After going around in a circle, the wire can obediently shrink into a ball.

.04 Wall patches
I'm not used to it:There was a crack in the wall, and I asked the workers to fix it. As a result, people don't use anything to fill the joint, they directly paste a piece of gauze on the surface of the gap, and scrape putty on the gauze, won't it fall off after a long time?
Facts:The "gauze" pasted has a scientific name, called "hanging net". If the gap is not large, the worker usually chooses to repair it by hanging a net. The net is generally made of nylon, so there is no need to worry about rotting later.
Use a mesh to separate the gap from the putty so that cracks in the wall do not extend to the surface. In other words, it is the hanging net that separates the putty and latex paint on the surface from the cement on the bottom layer, which is more durable than direct caulking.
.05 Brush the edges
I'm not used to it:The latex paint walls of my house are painted with roller brushes (or spray brushes), but the workers are painting with small brushes in the corners. Won't the paint on the edges thicken so that?It must be that the skills of the workers are not good.
Facts:Whether it is a roller brush or a spray brush, the edge of the wall is not treatedThe main reason is that the latex paint is afraid of accumulating in this position。The latex paint on the edges is trimmed little by little with a small brush.
As for the thickening of the paint, it does occur. But on the one hand, the paint surface on the edge will not be noticed and will not affect the appearance. On the other hand, proper thickening of the corners can also avoid paint cracking to a certain extent.
.06 Adhesive baseboard
I'm not used to it:Glue the baseboard directly with glass knotsHow much formaldehyde will this add to the room, and the glass is glued, can it be paved with cement mortar more strongly?
Facts:Contrary to what I was worried about, other than the tile baseboardGlass adhesive is much stronger than cement mortar。Therefore, the baseboard made of non-ceramic tile material is fixed with glass glue, which is now the mainstream practice.
The environmental protection of glass glue is not so terrible, as long as it is a high-quality neutral glass glue, there will be no pollution and odor problems. If you are not at ease, you can bring your own anti-mildew glass glue, which is more environmentally friendly and more durable.
