How to choose a waterproof coating? How to choose a waterproof coating?

1. Look at the waterproofness of the product. The quality of waterproofness determines the best quality of a product. 2. Look at the environmental protection of the product. If you choose a toxic waterproof coating, it will release toxic gases for a long time, which is harmful to the human body. 3. Look at the authenticity of the waterproof coating.

For the purchase of waterproof coatings, it is necessary to choose waterproof coatings with good water-resistant effect, good moisture-resistant effect and healthy and environmentally friendly waterproof coatings. In addition, we should choose waterproof materials with high tensile strength and good aging resistance.

Choose the most expensive one, you get what you pay for, choose the paint type for the floor, and choose the rigid one for the wall. In this way, when tiling, the wall tiles are not easy to fall off.

Waterproofing works are the most important in the renovation process, when doing waterproofing worksWaterproof coatingsIt is also different, different building parts, the requirements for waterproof materials are also different. Each material has its own strengths and weaknesses, a material can not cover the world, there is no good material used anywhere, all kinds of materials can only complement each other, and can not be replaced, each has a useful place. So how to choose a waterproof coating?

Below we will bring the selection method of waterproofing coating according to different positions for your reference.

How to choose waterproof coatings:

1. Waterproof bathroom

Because it is indoor, it is not greatly affected by the climate, and the temperature difference is small, so you don't have to pay too much attention to its elongation when choosing waterproof coatings; The structure is complex, there are many pipes, and the area is small, obviously, it is not suitable for the waterproofing membrane of such a narrow bathroom.

2. Waterproof roof

Long-term exposure to the sun, greatly affected by the climate, should be selected large elongation, high tensile strength, good weather resistance waterproof coating.

3. Underground waterproofing

The underground is generally humid, and the waterproof material must have good water resistance.

4. The wall is waterproof

Concrete structures such as underground structures, subways, civil air defense, roads and bridges, pools, sewage pools, hydropower stations, nuclear power plants, water conservancy projects, etc.

That's itWaterproof coatingsHow to choose? Choose the full content of the method according to the different locations.

Here's how to choose:

1. Polyurethane waterproof coating.

The cured coating film has excellent comprehensive performance, and can form a continuous, elastic, seamless, and integral coating film waterproof layer on the base layer with complex shapes. Strong adhesion to various substrates, strong adaptability to substrate expansion, deformation, cracking, etc., known as "liquid rubber" in foreign countries, whether in terms of performance, quality, effect, or economy, etc., has been recognized as the best waterproof coating.

Scope of application: suitable for basement, toilet and bath, kitchen, pool, cold storage, floor and other waterproof projects.

2. Acrylic waterproof coating.

It is a water-based waterproof coating, which forms a jointless waterproof layer after curing, which is environmentally friendly, has good waterproof performance, is easy to operate, can adapt to various complex waterproof substrates and other advantages, and can be constructed on wet substrates. The acrylic elastic coating with 100% pure acrylic emulsion as the base material has excellent weather resistance, and has the dual functions of waterproof and decoration. The coating film has the characteristics of low temperature resistance and high elongation.

Scope of application: pretreatment of wall corners, pipe periphery and yin and yang corners; Waterproof and moisture-proof parts of non-long-term flooding such as toilets, kitchens, floors, balconies, and non-exposed roofs.

3. Polymer cement waterproof coating.

It is a water-based coating, non-toxic, harmless and non-polluting, and is an environmentally friendly coating. The resulting coating film has high tensile strength, good water resistance and weather resistance. It can be applied on a wet base and bonds firmly to the base layer. It has the characteristics of high tensile strength and firm adhesion with the base layer.

Scope of application: suitable for waterproof and moisture-proof toilets, kitchens, floors, balconies, and non-exposed roofs.

4. PMC polymer modified cement-based waterproof gray.

It is a two-component cement-based polymer modified flexible rigid waterproof coating material composed of high-quality acrylic emulsion and a variety of additives, and then composed of inorganic powder composed of special cement and a variety of fillers.

What is a waterproof coating:

Acrylic waterproof coating is a one-component water-emulsion waterproof coating prepared by adding other additives with pure acrylic polymer emulsion as the base material. The waterproof film formed by the waterproof coating after curing has certain extensibility, elastic-plasticity, crack resistance, impermeability and weather resistance, which can play a role in waterproofing, seepage prevention and protection.

The waterproof coating has good temperature adaptability, easy to operate, and easy to repair and maintain.

When buying a waterproof coating, you need to look at its performance and whether it is environmentally friendly. How to choose the waterproof coating? This site will take you to find out.

1. When purchasing waterproof coatings, we should distinguish between flexibility and rigidity.

When we buy waterproof coatings, we don't know that waterproof coatings are rigid and flexible, flexible waterproof coatings are formed through chemical reactions to form a film, leaving the building structure and environmental moisture, so that we can achieve several rounds of waterproof effects. Rigid waterproofing coatings can improve the permeation resistance of the concrete base by increasing the density of the concrete base and reducing the porosity. There is no good or bad difference between the two waterproof coatings, and the choice of coatings is determined by different decoration environments.

The flexible waterproof coating has good extension performance and is more suitable for the decoration of new and old houses. Although rigid waterproofing coatings have a poor ability to adapt to deformation, it has better hardness and strength, so it is suitable for moisture resistance.

2. Choose different waterproof coatings for different waterproof parts.

Different spaces have different performance requirements for anti-tung stuffy coatings, and when choosing waterproof coatings, it is necessary not only to distinguish between flexible and rigid waterproof coatings, but also to select waterproof coatings according to different parts. If you want to achieve the best waterproof effect, then make the best use of materials and materials.

3. Choose waterproof coatings with environmental certification.

Some families think that these areas are not very large when they do waterproofing projects in bathrooms and kitchen lamp rooms, and they will use cement and tiles on them after using waterproof coatings, and they feel that no matter what waterproof paint they choose, they will not cause pollution. To be precise, if an inferior waterproof coating is used, but due to the concealment of the waterproofing layer, the inferior waterproofing paint will pollute the indoor environment for a long time. Therefore, it is necessary to choose waterproof coatings with environmental protection certifications (such as 10-ring certification, EC1 certification, etc.).

1. In the alternating environment of dry and wet, the waterproof material can basically be solved. For waterproofing toilets and baths, it is most appropriate to use the waterproof combination of "rigid walls and soft floors". Polymer cement waterproof sand with clear slurry is used for wall (tiled), and polymer cement waterproof coating (flexible) is used for the ground to prevent the impact of base surface deformation.

2. In the long-term humid environment, such as reservoirs, anti-corrosion pools, etc., due to long-term water storage, the volume of the waterproof coating will expand, the density will decrease, and the polymer cement waterproof with good air permeability will not work, and it is more suitable to use polyurethane waterproof coatings with high strength, large elongation, excellent water resistance and acid and alkali resistance.

3. You can smell the smell of waterproof coating, and choose a light and elegant taste, and there will be no pungent smell. When buying waterproof paint, you can first open the lid and ask it for the taste to determine whether it is a good paint or not, and then decide whether to buy it or not. Don't listen to the shopping guide, be sure to smell the smell yourself.

4. Before purchasing, we must first calculate how much area we need to use, and then buy a suitable waterproof coating. You can ask a renovation company or merchant to help you estimate how much paint you need for your home and then make a purchase.

When purchasing waterproof coatings, we should pay attention to the selection according to the characteristics of the use environment, and the quality of the paint can be judged by smelling, and the usable area should be calculated before purchasing.

1. Choose different materials according to the building structure. Different materials and materials of building structures have different requirements for waterproof coatings, and polymer water-based coatings should be preferred for concrete and cement mortar base layers; The lime slurry base layer preferentially selects polyvinyl alcohol water-based coatings; Wood base and metal base layer are preferentially selected for various solvent-based coatings.

2. Select according to different parts of the building. Different parts of the building have different requirements for its exterior decoration and maintenance, such as the interior wall paint used in the interior wall, people are close, can see clearly, and can touch, so the application of the paint has strong adhesion, delicate texture, differentiation resistance, and good air permeability; Kitchen, bathroom, washroom coatings should have waterproof, mildew-proof, easy to wash and scrub performance.

3. Select the distance time between the decoration of the building and the next decoration. If the distance between the current decoration of the building and the next decoration is long, the paint with good durability should be selected; If the distance is short, a paint with poor durability can be used. The above roughly introduces an aspect to be paid attention to when choosing waterproof coatings, pay attention to these points, and only by doing a targeted can we really ensure the quality of construction and reduce costs.
