It’s easy to maintain resin waterproof agent.
Not to mention the problem of formaldehyde, the construction of hard decoration alone is certainly impossible.
When the time comes, focus on the ceiling downstairs and the walls of the next room with waterproof layer.
There are two things to pay attention to in the water storage test.
On the contrary, if the humidity is small, the curing time of silicic waterproof agent is long and that of resin waterproof agent is short.
In order to accelerate the drying of the waterproof layer, some workers will use an electric fan to blow against it, which is even more undesirable.
The fast-paced life makes us pursue speed all the time.
Too much water will also affect the effect of silicic waterproof agent.
But there are also fake ones.
However, it should be prevented from being blown by the wind.
So what is “completely dry”? Temperature and humidity have a great impact on the drying speed.
Take the waterproof construction we want to talk about today.
The correct way is to press on the waterproof layer with your fingers.
After the first water storage test is completed, check whether the waterproof construction is in place.
[3] water storage test time many people know that water storage tests should be carried out in waterproof places, but few people really do it.
Some workers gently touch with their fingers and start construction when they find that the surface is not sticky.
Decoration is not a thing that can pursue speed, because many times we have to do more than construction, but “wait”.
Don’t leave a dead corner that doesn’t spray water.
The waterproof layer in the family generally needs to be painted with 2 ~ 3 layers of waterproof agent.
It is dry only if it does not stick to your hands under this force.
After each layer is brushed, wait until it is completely dry before brushing the upper layer.
If the humidity is high, the curing time of silicic waterproof agent is short and that of resin waterproof agent is long.
The more layers of waterproof agent, the better.
The curing method shall be determined according to the type of waterproof agent.
I have seen the owner brush 7 layers of waterproof agent in his home, which is also undesirable.
Moreover, water cannot be poured directly on the waterproof layer.
If the water in the waterproof layer evaporates too fast, it will lead to surface cracking.
We have to wait enough time.
Statement: [building waterproof Engineering] release.
It’s best to use a watering can when spraying water.
I saw an advertisement of a decoration company two days ago, saying that the blank room can be checked in in in 15 days.
This practice is actually inaccurate.
The surface is dry, and the inside is dry without surface.
In case of water leakage, dripping and seepage, it shall be repaired immediately, and the waterproof layer shall be cured and tested again.
The best choice is to brush 2 ~ 3 layers thinly.
Resin waterproof agent needs to be dried and cured.
When curing, spray water on the waterproof layer, usually two or three times a day.
Therefore, after brushing the resin waterproof agent, you should avoid opening too many windows.
Needless to say, the method of water storage test is to block all drains and inject water into the ground.
Before the water injection test, you should also say hello to your neighbors and ask them to help see if there is water leakage in your home.
Just hang it in the bathroom.
Household waterproof agents are generally divided into resin type and silicic type.
If the bottom layer is not dry, another layer of waterproof will be brushed, which will lead to the accumulation of water in the bottom layer and the cracking of the waterproof layer.
The waterproof layer needs to be exposed to the air for maintenance in order to better form the waterproof membrane and have a longer service life.
The curing time generally takes 3 ~ 7 days, mainly depending on the humidity of the room.
This approach is actually wrong.
One is the number of times and the other is the time.
【 I 】 the so-called “waterproof layer” in construction time is to brush the waterproof agent on the wall and ground, and form a film similar to plastic cloth after it is dried.
Silicate waterproof agent needs to be cured with water to make the waterproof layer absorb water, so that it is not easy to dry and crack.
Experienced workers will judge whether it is dry by touching it.
If the waterproof layer is too thick, it will affect the drying of the bottom waterproof agent, resulting in water separation and cracking of the waterproof layer.
[II] after the waterproof layer is completed during the maintenance time, many users can’t wait to carry out the water storage test, and then start pasting ceramic tiles.
However, there is often more than one waterproof layer.
After water injection, it needs to be observed for 24 ~ 72 hours.
The number of water storage tests is generally two.
The second water storage test is to check the damage to the waterproof layer during the tiling process after the tiling is completed (or the whole room is installed).
Generally speaking, the drying time takes 2 ~ 4 hours.
It contains more water and needs to be evaporated slowly.
