What is good for waterproofing in the bathroom?

Toilet waterproofing: one-component polyurethane waterproof coatings, non-tar polyurethane waterproof coatings, acrylic waterproof coatings, JS composite waterproof materials, cement-based permeable crystalline waterproof materials are better, detailed as follows:

1. One-component polyurethane waterproof coating:

One-component polyurethane waterproof coating is a reactive flexible waterproof coating made of isocyanate and polyether as the main raw materials and various additives. The product has good physical properties, strong adhesion, and cures at room temperature and humidity. Natural leveling, good extensibility, can overcome the leakage caused by cracking of the base layer.

The product has high strength, high elongation, high solid content and strong adhesion.

2. Non-tar polyurethane waterproof coating:

The non-tar polyurethane waterproof coating is a two-component material, which uses water as the chain extender, which avoids the toxicity of the amine chain extender, and forms a rubber waterproof layer with elasticity and no joints after curing. It can be applied with moisture (no open water) and strong adhesion to shorten the construction period. It has excellent resistance to oil, seawater and corrosion.

3. Acrylic waterproof coating:

It is a synthetic resin one-component waterproof coating made of pure acrylate copolymer or pure propionate emulsion, with an appropriate amount of high-quality fillers and additives. It has excellent weather resistance, heat resistance and ultraviolet resistance, basically no change in performance in the range of -30 to 80, good elongation performance, and can adapt to a certain range of cracking deformation of the base surface.

4. JS composite waterproof material:

The two-component waterproof coating composed of organic liquid material and a variety of additives and inorganic powder (composed of high-iron high-alumina cement or white Portland cement quartz powder and various additives) is a waterproof material with the advantages of high elasticity of organic materials and good durability of inorganic materials.

5. Cement-based permeable crystalline waterproof material:

The waterproof mechanism lies in using water as the carrier, through the guidance of water, with the help of strong permeability, it is transmitted and filled in the concrete micropores and capillaries, and biochemical reactions occur to form water-insoluble branch-like crystals. It is extraordinarily waterproof. Two layers of the material are applied at the concrete interface to withstand the above water pressure.

The well-known waterproof coating brand has Aili, which is an imported product from the United States, which has no peculiar smell and can effectively remove the peculiar smell in the bathroom, antibacterial and mildew-proof, so that the interior can be kept bright and white for a long time. Because there are many water stains in the bathroom, and the air is not well dredged and humid, you can make a mortar waterproofing agent protective layer to increase the strength of the wall and improve the puncture resistance.

1.One-component polyurethane waterproofing coatings:

The waterproof coating is a reactive flexible waterproof coating, which has good physical properties, strong adhesion, and curing at room temperature and humidity.

2.Non-tar polyurethane waterproof coatings:

The waterproof coating is a two-component material, using water as the chain extender, which avoids the toxicity of the amine chain extender, and forms a rubber waterproof layer with elasticity and no joints after curing.

3.Acrylic waterproof coating:

The waterproof coating is made of pure acrylate copolymer or pure propionate emulsion, adding appropriate fillers and additives, and is a synthetic resin one-component waterproof coating.

Composite waterproof material:

This waterproof coating is a waterproof coating composed of organic liquid material and inorganic powder, which is a kind of waterproof coating that has the advantages of high elasticity of organic materials and good durability of inorganic materialsWaterproof material. It is a new type of waterproof material developed after absorbing foreign advanced technology.

5.Cement-based permeable crystalline waterproofing material:

The waterproof coating is a waterproof material composed of Portland cement, quartz sand, special active chemicals, etc. Thanks to the strong permeability of water, chemical reactions and water and leak resistance are realized.

From a safety point of view, it is better to go up the bathroom water pipes and wires than to go down. However, many "guerrillas" are greedy for labor-saving, and water and electricity go to the ground, and even dig grooves and round holes in the bathroom.

All kinds of sewer pipes in the bathroom can not be changed, try not to change them; In case of change, you must not use cement mortar to fill the pores, and you must plug the leakage king to fill it three times. A slope should be made in the threshold of the bathroom, painted high to prevent the water from flowing backwards to the outside room, and the threshold stone must be slightly used with fine cement mortar to plug the leakage Wang wet paste.

There is more moisture in the bathroom, so it is necessary to pay attention to the waterproof treatment during the decoration process, and the waterproof must be in place to avoid the problem of water leakage, and the later maintenance is more troublesome. Secondly, the choice of waterproof coating for the bathroom is also very important, what materials are used for waterproofing in the bathroom? It can be mainly divided into the following types:

1.Cement mortar waterproof materials Cement mortar waterproof materials are common toilet coatings, which should be matched with cement mortar in a certain proportion to form a uniform liquid. When batching, use a stirrer to stir, and slowly add powder for mixing and stirring while stirring (you can add an appropriate amount of water to adjust the viscosity, but it is best to add water before adding powder), and fully stir and disperse to achieve uniform no powder ball, no precipitation, and the prepared material should be used up within 2-3 hours.

2.Polymer polymer waterproof material Polymer polymer waterproof material is composed of a variety of water-based polymers, and then mixed with various additives of high-quality cement, the flexibility of the polymer and the rigidity of the cement are integrated, making it excellent in impermeability and stability. Its advantages are convenient construction, low cost, cost-saving and non-toxic and environmentally friendly.

3.Acrylic toilet waterproof material The biggest advantage of acrylic waterproof coating is that when the paint is applied, the coating will form a conjunctiva, which has strong elasticity and ductility, which is very suitable for use as a toilet waterproof.

And it can be constructed on the wet base layer, with high bond strength, firm combination with the base layer and the outer protective decorative layer, green and environmental protection, no pollution and no peculiar smell. The above three kinds of bathroom waterproof coatings are used more, and the effect is also very good, and it is one of the preferred materials for family bathroom decoration. When carrying out waterproof construction, it is necessary to follow the specific steps, first of all, to level the floor, first use cement mortar to level the ground (especially the house that is re-decorated), and then do waterproof treatment.

Secondly, it is necessary to do a good job in the waterproofing treatment of key parts, and the joints between the wall and the ground, as well as the joints between the water pipes and the ground, are the most prone to water leakage, so the waterproofing of these places must be done meticulously and not sloppily.

Bathroom waterproofing can be used:

1. Cement mortar waterproof material is a commonly used coating in the bathroom, which should be matched with cement mortar in a certain proportion, so that a uniform liquid can be formed. When batching, be sure to use a stirrer to stir, and you have to slowly add powder to mix and stir when stirring, you must fully stir and disperse, in order to achieve a uniform and no dough phenomenon, you must remember that the prepared material should be used up within 2-3 hours.

2. Polymer polymer waterproof material This material is synthesized from a variety of water-based polymers, and then when you use it, you must remember to add various additives to the composition of high-quality cement, you must know that the flexibility of the polymer and the rigidity of the cement are integrated, so that it can be formed in terms of impermeability and stability. The advantages of this material are that it is easy to construct and relatively low in cost, and it is also a non-toxic and environmentally friendly product.

3. What material is good for acrylic toilet waterproofing, acrylic waterproof coating It says that its advantages are: for example, after you finish the paint, this material will form a conjunctiva, and such a conjunctiva It also has strong elasticity and ductility, it can be said that it is also very suitable for a waterproof material used in the bathroom. Moreover, this product does not have high requirements for construction, it can be constructed on a wet base layer, with high bonding strength, and it is also a green and environmentally friendly product.

At present, there are four mainstream waterproof materials on the market: polyurethane, acrylic, polymer, polymer, cement, mortar.

These four types of waterproof coatings are cement mortar, polymer, acrylic, and polyurethane in terms of waterproof performance.

1.Polyurethane coating, known as "liquid rubber", is one of the waterproof coatings with the best comprehensive performance. The coating film has toughness, high tensile strength, good elongation, corrosion resistance, strong resistance to structural expansion and deformation, and has a long service life.

2.Acrylic was the first and largest application in eco-friendly paints and coatings. The biggest feature of this material is that it can be diluted with water, it is a water-soluble material, and it is colorless and odorless (lacquer can be mixed with colorants according to needs), but it is an unusually dense waterproof material after the conjunctiva.

Therefore, the current lacquer basically does not have the same paint smell as before (the previous paint was mixed with gasoline or thinner). This material has considerable elasticity and ductility after conjunctiva, which determines that it will not break with the settlement and dislocation of the base layer. This material is currently priced at a moderate price and is the first choice for waterproofing materials for home improvement.

3.Polymer cement waterproof coating (referred to as JS waterproof coating) is a two-component waterproof coating composed of synthetic polymer emulsion (such as polyacrylate, polyvinyl acetate, styrene-butadiene rubber emulsion, etc.) and various additives. This kind of material is environmentally friendly, firm adhesion to the substrate, fast drying, but it is mostly a two-component material, according to the instructions to guide the ratio of liquid and powder, the important point is that if some manufacturers add too much talcum powder to the material will greatly reduce the material performance, should choose the product produced by the brand manufacturer.

4.Mortar waterproof coating is a two-component water-based waterproof mortar composed of organic emulsion material composed of acrylic emulsion and a variety of fillers, with inorganic powder composed of special cement and a variety of fillers, and formulated in a certain proportion. This kind of coating belongs to water-based coatings, non-toxic and harmless, non-polluting, is a real environmentally friendly coating, it can be directly constructed on the surface of concrete and firmly bonded, convenient construction, not limited by the moisture content of the base layer, fast drying, short setting time, 2 hours after the construction can be pasted on the surface of the tile.

However, due to the fact that this kind of material is a rigid waterproof coating, it lacks elasticity after film formation, and will affect the waterproof effect with the settlement and dislocation of the building, and is generally suitable for parts with relatively stable structure.
