What are the types of waterproof coatings for toilets?

1. SBS modified asphalt waterproofing membrane: This membrane has good high temperature resistance, can be used in the temperature range of -25 to +100 degrees, has high elasticity and fatigue resistance, as well as up to 1500% elongation and strong puncture resistance and tear resistance. It is suitable for waterproofing projects in cold areas, as well as industrial and civil buildings with large deformation and vibration.

1. Bathroom decoration is a major event in home decoration, and bathroom waterproofing is a key point of its decoration design. The quality of the bathroom waterproof coating has a direct impact on the waterproof effect of the bathroom, so to do a good job of bathroom waterproofing, the first thing is to choose a good bathroom waterproof coating.

Second, the types of waterproof coatings in the bathroom.

1. Polyurethane toilet waterproof coating.

It is mainly liquid, and it is divided into two types: tar type and non-tar type. Non-tar paint is one of the most commonly used toilet waterproofing materials on the market today. It is a curing agent with non-tar substances, such as a curing agent composed of asphalt, additives and fillers.

This kind of toilet waterproof coating is divided into two groups, group A is the curing agent, and group B is the main component of the material. This material has stable quality, low pollution, good aging resistance, good adhesion and water enhancement.

When users buy this type of toilet waterproofing coating, they must buy two groups together and mix them. At present, non-tar waterproofing coatings occupy the majority of the market share, and consumers can easily buy them.

2. Cement mortar toilet waterproof coating.

As one of the emerging waterproof materials, it is also very popular with consumers, in fact, its material is a special adhesive (a bit like a special glue) mixed with fine cement and sand dust.

3. Acrylic bathroom waterproof coating.

It is the earliest and largest application in eco-friendly paints and coatings. The biggest feature of this material is that it can be diluted with water to make a water-soluble material, and it is colorless and odorless (lacquer can be mixed with colorants as needed), but it is an unusually dense waterproof material after the conjunctiva.

4. Polymer polymer waterproof coating.

The materials are mostly made of rubber-derived multi-chain polymer materials. It has good ductility and elasticity. It is colorless and odorless, and has a good environmental protection type.

However, the characteristics of his rubber source are that it has great viscosity before drying, and any small bumps and contacts will be damaged by the waterproof film, and the thickness of the brush cannot be brushed, and it is basically transparent after drying, and the visual effect is not good.

Bathroom waterproof coatings, now more common are:

Waterproof slurry for kitchen and bathroom.

K11 waterproof slurry universal type.

K11 waterproof slurry flexible type.

JS polymer cementitious waterproofing coatings.

Among these kinds, it is most recommended to use kitchen and bathroom waterproof slurry, because more than 80% of the bathroom leakage is concentrated in the yin and yang corners, pipes, sanitary ware, floor drains and other places, so it is recommended to use special kitchen and bathroom waterproof slurry when doing waterproofing, first use quick-setting repair mortar to carefully paint these parts that are easy to seepage, and then use permanent waterproof slurry to do waterproofing as a whole, so that the effect of special waterproofing is better, and the waterproof life is longer.

At present, there are roughly 4 types of waterproof coatings on the market.

1: After the hard mortar is brushed, there is no need to treat the coating, and it can be directly tiled, which is convenient for construction. It is mostly used on the back surface of the top surface.

2: Even if the base layer is deformed and cracked, the flexible mortar will not affect the waterproof effect. It is mostly used on the surface of the water such as walls and floors.

3: Acrylate: pure liquid, ready to use out of cap.

Water-based, which can be melted into water, is easy to combine with the ground crevices to form a strong waterproof layer, and the waterproof effect is better than that of flexible mortar. After brushing, surface treatment such as brushing or sand blowing is required to increase friction and make it easy to tile. Due to their excellent waterproofing effect, flexible mortars and acrylates are more suitable for use in environments with long-term immersion in water.

4: One-component polyurethane: indoor and outdoor use, very thick after brushing, about 3 mm, and the elastic tension is more than 300%, very elastic, any cracking of the substrate will not make it crack, waterproof effect is the best.

Although the safety performance is controlled in the environmental protection requirements, the smell of this waterproof coating is larger, which is difficult for ordinary people to accept, and the environmental performance of a few brands is not up to standard. Polyurethane is gelatinous and very thick, and a scraper is required for construction, which is very laborious and complex. After brushing the paint, it is necessary to carry out surface treatment, brushing or sand to increase friction, and it is easy to apply tiles.

Mainly: polyurethane, acrylic, polymer cement, cement mortar. In terms of waterproof performance, the best of these four types of waterproof coatings is polymer polymers. > polyurethanes. >Acrylics》Cement mortar.
