What are the commonly used waterproofing agents cement mortar How to construct

Commonly used waterproofing agent cement mortar are: chloride metal salt waterproofing agent cement mortar, inorganic aluminum salt waterproofing agent cement mortar.

Metal soap, salt, waterproofing agent, cement mortar.

Silicon waterproofing agent, cement mortar, etc.

1.Conception. Waterproofing mortar is made by mixing various waterproofing agents in cement mortar.

Waterproofing agent is an admixture composed of various inorganic or organic chemical raw materials, which can be incorporated into the mortar to improve the impermeability of the mortar. According to the chemical composition, it can be divided into four categories: chloride metal salt waterproofing agent, metal soap waterproofing agent, silicone waterproofing agent and other waterproofing agents.

2.The construction process of waterproofing agent cement mortar.

Before construction, the ground and vertical surface of the waterproof base must be flat, rough, clean and wet, the general waterproof mortar layer must be completed twice, first the waterproofing agent water distribution = about 1:8 and the thickness of the cement mixing plaster to do the bonding layer, and then wipe the waterproof mortar 10mm-20mm thick when the plain ash is initially set, and the retarding period must be cured and compacted 1-2 times. The curing method is the same as the conventional cement curing method, if you need to stick the tiles, you can wipe out the matte surface before the complete strength (the basement or difficult waterproof project with large water pressure can be repeated once or twice according to the above process according to the site conditions).

When making waterproof mortar, if there are special parts such as pipe fittings, floor drains, and columns in the bathroom, they need to be treated first. Schematic diagram 4 method: drill around its roots with a drill to build a concave type, clean, damp, and then use plain ash to wipe the convex type (slope type) around its roots, form a whole with the thick plain ash binding layer above-mentioned above, and do waterproof mortar when the initial setting.

When repairing leakage works, when the original foundation is smooth, it is necessary to drill a hemp surface with a drill.

When spraying and brushing exterior wall finishes, the original solution of waterproofing agent (without water) can be sprayed and mixed with liquid decorative paint 2-3 times, which can be added according to the color of the paint, and the general waterproofing agent is about 1: (1-3), mixed in the paint, and the spraying process of the paint remains unchanged.

The polymer in the polymer cement mortar is a kind of dispersion, good cohesiveness of polymer materials, after the mortar is solidified and hardened, it is filled in the pores of the mortar structure, wrapping the surface of the solid particles, so that the hardened mortar body has good compactness and impermeability, plus the surface of the mortar can form a dense layer of polymer film after the evaporation of water, itself has good waterproof and impermeable properties, so there is no need to mix with waterproofing agent.

Waterproofing mortar is suitable for basement waterproofing and roof waterproofing.

1. Basement waterproofing.

The basement is usually damp and has leakage problems. The use of waterproof mortar can effectively prevent groundwater, rainwater and other liquids from seeping into the basement inside, and ensure that the basement is dry and comfortable. In underground buildings such as basements and tunnels, due to the high humidity and low temperature of the environment, it is easy to cause problems such as water seepage and dampness in the walls.

Therefore, the use of waterproofing mortar for waterproofing treatment can effectively prevent these problems from occurring.

2. Waterproof roof.

The roof is one of the parts of a building that are most susceptible to rainwater erosion. The use of waterproofing mortar can effectively prevent rainwater from penetrating into the inside of the roof and reduce the risk of roof leakage. The use of waterproof mortar for waterproof treatment can effectively prevent water stains from penetrating under the walls and floors, and avoid the occurrence of problems such as mold breeding and damage to furniture.

1. Understand product performance: Different waterproof mortars have different properties, such as water resistance, weather resistance, crack resistance, etc. When choosing, you need to choose the right product according to the actual needs.

2. Check the product quality certificate: When choosing waterproof mortar, you need to check its product quality certificate, such as ISO9001 quality management system certification, building materials test report, etc., to ensure reliable product quality.

3. Pay attention to the construction environment: The construction environment of waterproof mortar is also very important, and it is necessary to avoid direct sunlight and high temperature environment, so as not to affect the performance and service life of the product.

4. Pay attention to the construction method: different waterproof mortar has different construction methods, and it is necessary to choose the appropriate construction method according to the product manual and the actual situation.

5. Pay attention to the storage method: the storage method of waterproof mortar is also very important, and it is necessary to avoid direct sunlight and high temperature environment, so as not to affect the performance and service life of the product.

Different brands of mortar waterproofing agent may be a little different in terms of proportion, so let's take Laoyal's mortar waterproofing agent as an example to talk about the construction method

1.Clean the construction site and sprinkle water to make it fully moist but there should be no stagnant water.

2.Wall: The total thickness of the waterproof layer (waterproof mortar + waterproof mortar) is not less than 10 mm for the wall, not less than 20 mm for the ground, and not less than 1800 mm for height.

1) Mix "Lauyer mortar waterproofing agent" with cement at 1:3 to form a waterproof mortar, and paint it once or twice on the base surface, with a total thickness of 2 mm.

2) After 20 minutes, after the waterproof mortar is dry, stir it into a waterproof mortar with "Laoyal" and cement and sand according to 1:2:6, and wipe it on the surface of the waterproof plain ash with a thickness of 8 mm.

After the waterproof mortar layer is solidified, it is cured by sprinkling water.

Waterproofing agent is often used in various construction sites, mortar waterproofing agent is one of them, many friends may not know much about mortar waterproofing agent, so how to use mortar waterproofing agent?

First, the use of mortar waterproofing agent.

First of all, clean up the sediment and debris of the base layer to keep the base surface clean, and then add water to mix the waterproofing agent evenly according to the ratio of 1:8 of silver and light, and then add cement and sand to continue mixing. Generally, the waterproof mortar is completed in two times, the bottom layer is first wiped with the plain ash layer, and then the second layer of waterproof mortar is wiped when the plain ash layer is initially set.

2. What are the characteristics of mortar waterproofing agent?

1. Good waterproofness.

Traditional waterproof measures generally use the method of blocking and separation, which cannot achieve the effect of waterproofing. The waterproofing agent can change the building structure, solve the leakage problem from the root, make the concrete void more dense, the compressive and tensile strength is higher, and the waterproof mortar can make the surface of the building have a permanent waterproof membrane, so that the base surface is not easy to deform, fall off, etc., greatly prolonging the life of the building.

2. Simple construction.

The construction method of waterproofing agent is simple, only need to be evenly adjusted according to the description, and then sprayed directly on the surface of the clean building, which greatly saves the construction period.

3. Super use.

Mortar waterproofing agent is a green and environmentally friendly product, no need to worry about harm to the human body, the temperature can be more than 5 degrees Celsius construction, a wide range of uses. Whether it is floor, roof, wall, ground, bathroom, kitchen, swimming pool and other areas can be waterproofed, and anti-freezing, anti-falling off, the waterproof life of the product can reach more than 10 years, only need to mix several types of chemical raw materials together, no need for large equipment. The cost is lower than waterproofing materials.

Conclusion of the article: The use method and characteristics of mortar waterproofing agent are introduced here, I hope it will be helpful to you.
