How to make it waterproof? Waterproof process?

How to do waterproofing? what is the process? Clean up the grass roots, the original wall ground surface should be solid, there should be no sand, ash or empty drum. Clean up the root of the upper and lower water pipes and plug the leakage. Paste the outline line with 10-15 inch wide beauty pattern paper according to the design and construction height of the wall. Once emulsion painting construction, the order from top to bottom, from the inside to the outside, do not miss the brush.

One of the procedures of the construction team for waterproofing: for the surface of the base layer to be coated with waterproof layer, dust should be removed and the mortar residue on the surface should be flattened. Brushes can be used to remove impurities such as dust where it is difficult to clean the root edge of the pipe. If there is uneven height or Yin-Yang angle is not smeared into a circular arc, it can be repaired with mortar. Before the base is waterproof, the pipe roots and floor leaks of the protruding floor and walls.

Grass-roots treatment: first of all, we should carry out ground treatment to ensure that the ground is clean, free from any sundries pollution, solid grass-roots surface, no peeling and so on. We also need to level the ground to ensure that the ground is flat without major defects and patching marks. Brush waterproof paint: before we brush the paint, we should ensure that the toilet is clean and dry. Waterproof paint to brush comprehensive, firmly combined with the grass-roots, there will not be bubbles, shedding and other problems.

Structure is self-waterproof. The commercial concrete of the corresponding impermeability grade used in accordance with the design requirements can only be used after passing the inspection. In the process of concrete pouring, the pouring sequence should be arranged reasonably to avoid the formation of cold joints. If a water stop bolt with a water stop ring is used for the tension bolt, after the wall formwork is removed, the 2cm is removed from the root of the tension bolt, the end rod of the bolt is burned by gas welding, the end of the bolt is coated with antirust paint, and the gap is filled with waterproof mortar.

Do waterproof process: grass-roots treatment before waterproof treatment, first of all to level the ground, which may cause cracking and leakage caused by uneven thickness of waterproof paint. Floor drain, wall corner, pipe heel and other joints to use high elastic flexible waterproof key brush, if there is toilet displacement, be sure to brush the corner of the joint between the wall and the ground several times, this place is the most prone to leakage.

What's the best way to be waterproof?

Correct method of waterproof base treatment We clean up the dirt such as sand, concrete and putty powder on the base surface, flatten the base surface on the ground, and there can be no appendages on the base surface. Then the hot melt modified asphalt coil is used to make the additional layer in the details such as water fall, pipe root, yin and yang angle before the construction of the waterproof layer.

Strengthen the treatment: use waterproof mortar to strengthen the pipeline root, wall corner and other positions to avoid leakage. Brush waterproof paint: brush the waterproof paint three times on the metope and ground base, each time should wait for a drying before you can continue, and the brush thickness needs to be maintained at more than three centimeters.

Brush cement paste: the mix ratio is cement ∶ water ∶ waterproof oil = 1 ∶ 0.8 ∶ 0.025 (weight ratio), first mix cement with water, then add waterproof oil to mix evenly, then brush evenly on the surface of the base with a soft brush, and then apply the bottom waterproof mortar. (2) for bottom mortar, use 1 ∶ 5 cement mortar, add waterproof powder with cement weight of 3% to 0.5%, water-cement ratio of 0.6 to 0.65, and consistency of 7~8cm.

There are many methods of indoor waterproofing, the following are some common methods: spray waterproof coating: you can use spray waterproof coating for wall and ground waterproof treatment, this method is relatively simple, but we need to pay attention to the quality of the coating and construction technology. Laying waterproof layer: laying waterproof layer on the ground or wall, such as waterproof film, waterproof roll material, etc., this method is more durable, but requires professional construction.

Strengthen the waterproof layer: for the walls that are particularly easy to seep, you can consider increasing the waterproof layer. Can lay waterproof glue, waterproof film and other materials to increase the waterproof performance of the wall. Pay attention to the details: when the wall is waterproof, we need to pay attention to some details. For example, corners, pipes, windows and other places need special treatment, sealants, waterproof tape and other materials can be used to ensure waterproof effect.

To prevent leakage and sand holes, wait for the first layer to dry and then apply the second layer. Pay attention to the intermittent mixing of the slurry during construction to prevent precipitation. The mixed slurry should be used up within 20-40 minutes. Non-load-bearing lightweight walls should be at least 8 meters high and the whole wall should be waterproof. The metope waterproof adjacent to the shower position should also be 8 meters high, and the height of the metope waterproof paint adjacent to the bathtub should also be higher than the upper edge of the bathtub.

How to construct EPDM waterproof roll material

The construction method of EPDM waterproof roll material is as follows: 1) Hot solution pasting method (1) using hot solution pasting method can reduce the project cost of waterproof layer, save the amount of adhesive and avoid the phenomenon of hollow in waterproof layer; (2) the base treatment is cement mortar leveling layer, which requires solid, flat, glossy and no bulging phenomenon. The grass roots must be dry.

The laying method of the coiled material should be determined according to the engineering type, structural characteristics, waterproof position and construction conditions, and the full bonding method or empty paving method can be adopted. The waterproof layer of EPDM coil can be divided into single layer and laminated structure, which should be according to the design requirements. For single-layer waterproof construction, the thickness of EPDM coil should be ≥ 5mm. Sticking method: it is a construction method in which all the coiled materials are bonded on the base by using a special base adhesive.

Construction practice of EPDM waterproof roll material smear base treatment agent generally mix the A material, B material and diluent of polyurethane waterproof coating according to the proportion of 1:2:3 by weight and stir evenly. Then dip the mixture with a long roller brush and apply it evenly on the clean and dry base surface. The coil material can only be laid after the base treatment agent is solidified and dried. The wire must be controlled before laying the roll, and the size of the coil must be calculated in advance to ensure that the laying is tight.

Construction process of empty paving method: roll material deployment location → cleaning lap area → coating glue → rolling lap parts → detail treatment → completion of EPDM waterproof roll material inversion method: it is a construction method of placing thermal insulation layer on waterproof layer. Empty paving method and inversion method can be applied to any underground and roof that can carry heavy loads. in general, the roof slope should not exceed 1:6.

In the waterproofing construction of ternary ethylene-propylbutyl waterproof sheet, five kinds of auxiliary base treatment agent, base adhesive, coil joint adhesive, coil end sealant and surface colorant are used. Base treatment agent: polyurethane (PU) two-component is used to seal the base layer and prevent the base from permeating water. Base adhesive: the use of neoprene (CR) single component, the use of CR high crystallinity to make a good adhesion between the sheet and the base.
