What are the types and choices of waterproof coatings?

Acrylic waterproof coating, acrylic waterproof coating, is made of pure acrylate copolymer or pure propionate emulsion, adding appropriate amounts of high-quality fillers and additives. It is a synthetic resin one-component waterproof coating. It is a water-soluble paint that can be diluted with water. It has greater elasticity and ductility after forming a film. It has a significant waterproof effect and is moderately priced. It is the best choice for home decoration.

Hard mortar waterproof coating, hard mortar waterproof coating, also called rigid mortar, the ratio of emulsion to mortar is 1:4, there is no need to apply it after finishing It is more convenient to lay the tiles directly on the first layer. After curing, the cement will fill the socket and will not leak water. The waterproof effect of the back surface is very good.

Polyurethane waterproof coating, polyurethane waterproof coating, can be used both indoors and outdoors. It is very thick after brushing, about 3 mm, and has an elasticity of more than 300%. It can be used on any substrate. It will not crack even if it cracks, and the waterproof effect is good. Polyurethane is gel-like and very thick, so you need to use a scraper during construction, which is very laborious.

Flexible mortar waterproof coating, flexible mortar waterproof coating, the ratio of emulsion to mortar is 5:4. It is elastic and will not affect the waterproofing effect even if the base layer deforms and cracks. .

What are the waterproof materials?

There are currently five main categories of home improvement waterproofing materials on the market, namely: flexible mortar, rigid mortar, polyurethane, membrane, and acrylic waterproof coating.

1. Flexible mortar

The ratio of emulsion to mortar is 5:4. It is elastic and will not affect the waterproofing effect even if the base layer deforms and cracks. It is mostly used on facing surfaces such as walls and bottoms, but cannot be used on back surfaces such as top surfaces.

2. Rigid mortar

Also known as rigid mortar, the ratio of emulsion to mortar is 1:4. There is no need to process the coating after finishing, and the tiles can be laid directly. , which is more convenient. After curing, the cement will fill the socket and will not leak water. The waterproof effect of the back surface is very good.

3. Polyurethane type

It can be used both indoors and outdoors. It is very thick after brushing, about 3 mm, and has an elasticity of more than 300%. Any cracking of the base material will not cause it to crack. , the best waterproof effect. Polyurethane is gel-like and very thick. It requires the use of a scraper during construction, which is very laborious.

4. Coiled materials

Most waterproof coatings on the market are water-soluble materials. Whether they are water-soluble or oil-soluble waterproof coatings, as long as they have passed relevant national environmental protection certifications, such as China Environmental label certification or CTC product environmental protection, quality certification, etc. These materials are environmentally friendly and reliable.

5. Acrylic waterproof coating

Acrylic waterproof material is made of pure acrylate copolymer or pure propionate emulsion, adding an appropriate amount of high-quality fillers and additives, and is a synthetic material. Resin-based one-component waterproof coating. It is a water-soluble paint that can be diluted with water. It has greater elasticity and ductility after forming a film. It has a significant waterproof effect and is moderately priced. It is the first choice for home decoration.

What are waterproof coatings?

The spaces that need to be waterproofed in home decoration mainly include bathrooms, kitchens, balconies, basements and other areas. The popular waterproof coatings for home decoration on the market are mainly these 4 types: polyurethane waterproof coating, acrylic waterproof coating, JS waterproof coating , K11 waterproof mortar. A layer of K11 waterproof mortar is generally applied to the outside of the kitchen and bathroom walls. This can reduce the hollowing rate when laying the wall tiles and ensure the quality of the paving. Let’s take a look at their respective characteristics:

Features

1. Polyurethane waterproof coating

① Can be directly applied to various wet or dry base surfaces Construction, strong bonding ability with the base surface, the polymer material in the application can penetrate into the fine gaps of the base surface, and has strong followability. And the application has good flexibility, strong adaptability to the expansion or cracking of the base layer, and high tensile strength.

② The construction is simple and the construction period is short. Once the coating film is formed, the coating film will be dense, the waterproof layer will be complete, there will be no cracks, no pinholes, no bubbles, and a small water vapor permeability coefficient. It will have both waterproof and functional properties. It has air isolation function and is relatively easy to maintain.

③Green and environmentally friendly, non-toxic and odorless, it can be prepared in various colors as needed and is harmless to the human body.

2. Acrylic waterproof coating

① It can be applied on a wet surface, using water as the dispersion medium. It is non-toxic, odorless, does not pollute the environment, and is an environmentally friendly product;

②Single component, cold construction, can be applied by brushing, rolling, spraying, scraping, etc.;

③Easy to form a film, the coating film has good aging resistance, extensibility, elasticity and adhesion ;

④The waterproof layer is a closed system with good overall waterproofing effect, especially suitable for the construction of base layers of special-shaped structures;

⑤It is suitable for non-long-term use on roofs, walls, bathrooms, basements, etc. Anti-seepage projects in flooded environments.

3. JS waterproof coating

①Constructed on wet surface, the coating film has strong toughness;

②Non-toxic and odorless, it can be used for waterproofing of edible pools;

③ High temperature resistance (up to 140℃), suitable for waterproofing of exterior walls and sloped roofs with facing materials, construction on facades, slopes and top surfaces, and can be used with base and facing bricks, roof tiles, cement Various outer materials such as mortar are firmly bonded.

④Adjust the proportion appropriately,gaps to improve the permeability resistance of the base layer. There is no good or bad distinction between these two types. It is mainly the different use places that determine flexibility and rigidity. Flexibility can meet slight structural deformation and can be used for renovation of old houses. It has poor rigidity and strain capacity but good hardness and strength. It is usually used for moisture-proofing.

2. Choose different waterproof materials according to different waterproof parts

Different areas have different performance requirements for waterproof coatings. Therefore, when choosing waterproof coatings, you should use them in a targeted manner according to different areas. Waterproof coating. Only when used in the right place can the best waterproofing effect be achieved.

What kinds of waterproof coatings are there? Which one is better?

Waterproof coatings can currently be divided into three types according to their development history. The first type of waterproof coating is ancient asphalt, the second is modified asphalt, and the third is currently common polymer coatings. Polymer waterproof coatings are available in reactive, emulsion and solvent types, with solvent type being the best option. The construction conditions are not high and the effect is good. Among them, CPC anti-leak agent is a solvent-based representative. The construction requirements of this anti-leakage agent are not high, and general marble, floor tiles, ceramic tiles, terrazzo, concrete, cement, etc. can be used and have a wide range of uses.

The construction cost of this kind of waterproof coating is not high, only 158 yuan per can.

If traditional or reactive emulsions are used, the cost is much higher.

The effect of this waterproof coating is long-lasting, permeable, and integrated with the building structure. As long as the building structure itself is not damaged, the waterproofing effect will continue. Requirements for attention when constructing this kind of waterproof platform coating: first ensure that the building structure is dry, and do not apply it when it is wet. If the gap in the leaking area is large, fill it with cement first, and then apply waterproof coating after the cement dries. After application, it is generally guaranteed to be allowed to dry for 24 hours, and then it can be put into use.

CPC waterproof coating is a colorless, non-toxic, odorless and harmless liquid. It has no side effects on the human body, even if there are elderly and children. Hope my answer can solve your problem.
