Do this 3 points! Bathroom waterproof is not difficult

As we all know, the function of the bathroom is almost entirely related to water, so this step is particularly important in the decoration of waterproof, then how can waterproof do it? Today, I told you about the three points you need to know when waterproofing. It's not difficult to grasp the waterproof!

First, the base layer should be flat enough to be clean enough

The basal layer should be clean and the adhesion of the cement mortar to the bottom will be good, but there is a master who is too lazy to clean the soil and sand. In addition, if you want to knock out the original floor, the basement layer will be very uneven, you have to make a rough bottom of the cement first, and do a good job. After waiting for the cement to dry, apply a waterproof layer. If the concrete floor is not too rough, it is not necessary to make a bottom, directly on the waterproof layer.

Waterproof layer is painted waterproof slurry, the wall surface must be 抺2 to 3 times. But it's not that the more layers, the thicker the better. So I once heard the designer say, "We have done a very solid waterproof job. We charge more than seven layers, so it's more expensive." Thick, different rates of water dispersal in the surface and inside, but it is not easy to crack, it is not a good thing.

In construction, waterproof materials must be “thinly coated with multiple layers”, that is, evenly coated and thinned, and coated in multiple layers, because they are thin and can be dried thoroughly. Waterproof paste is required to dry out before it can form "film" to waterproof. Each time the direction of painting is reversed, the first line is painted vertically and the other line is painted horizontally.

In the floor drain, casing, sanitary ware roots, yin and yang corners and other parts, can be further brushing, but before the cement mortar in the root to make rounded corners, only on the waterproof material. When applying waterproof paste, if it flows to the inside corner, it must be scraped off so that the product is not thick enough to crack.

But the question is, how is it called "dry"? Many masters have different opinions. Some people think that hand touch is not sticky or peeling. However, according to the K11 waterproof method, the manufacturer thinks that “it must not damage the surface film when walking on the floor” can be calculated. As for why people will care about the concept of "dry," it is because it directly relates to construction time. Some masters will regard it as "not sticky" to save time. If the paint does not dry out, the "membrane" is not easy to form, and it will be easily cracked in the future. Naturally it will leak.

Third, after the waterproof slurry coating, curing 3 to 7 days to tiling

Common waterproof pastes are available in two materials: resin type and silicic type.

The resin type should be dried and maintained, but remember "Don't use a fan to blow it," but there is a master to accelerate drying, which is not good.

Silicic acid-based waterproofing materials have to be “sprayed” for conservation. This is very important. The material is to have water to crystallize. The longer the crystals are, the denser and the more complete the caulking.

In addition to the bathroom, generally there will be waterproof after the balcony, then the kitchen, living room and restaurant should not be waterproof? This depends on personal choices, and most of them have not been done; we have to return to the reasons for doing so: we often add water or a layer of water to wash the floor. From this principle, the restaurant will not be used. If you have the habit of washing the kitchen, of course, you can also make it waterproof in the kitchen.
