Steps to do waterproof indoors

A, construction preparation:

1, waterproof construction, should first check the grassroots, after confirmed qualified, can handle the process handover, and then waterproof construction. The installation of sanitary ware and water supply and drainage pipes between bathroom and bathroom should be closely coordinated with waterproof construction according to the construction arrangement, and the process handover and finished product protection should be done well.

2. Bathrooms with poor natural light should be provided with adequate lighting * Bathrooms with poor ventilation should be equipped with ventilation equipment.

3. The "three inspections" system of self-inspection, handover inspection and full-time personnel inspection shall be established in the construction of indoor waterproofing works, and complete inspection records shall be kept. The construction of the next working procedure shall not be carried out without inspection and confirmation of the previous working procedure.

Second, indoor waterproof steps:

1, after the grass-roots cleaning, the key parts such as the angle of yin and yang, expansion joints and construction joints should be treated. Especially for the parts that are not easy to be painted such as drainage holes, it is necessary to strengthen the painting of waterproof primer for 2-3 times.

2, ready to waterproof coiled material, waterproof coating, basic coating and adhesive coiled material coating must be distinguished. Priming. In order to improve the adhesive force between the waterproofing membrane and the base, the primer can be applied repeatedly, evenly and thoroughly, and fully penetrated into the concrete base to improve the adhesive strength and shear strength.

3. Waterproof coating must be prepared according to the product description, and the ratio is A:B=2: 1, and the amount of preparation matches the actual amount on site.

4. Waterproof coating should be stirred evenly for about 3-5 minutes, and the mixture of component A and component B should be stirred evenly.

5. According to the area that needs to be painted on site, evenly mixed waterproof coating shall be painted, and the base coating is larger than the area of the bonded coil. The waterproof coating shall not exceed 30 minutes at the latest from the end of mixing to the end of brushing.

6. After the first coating is completed, it takes about 4-8 hours to coat the second and third coatings again. The thickness of the first coat is 0.5mm, the second coat is about 0.5 mm, and the third coat is about 0.5 mm. Before applying the second coat, you must wait until the first coat is completely cured.

7. When the coiled material is bonded, the second coating should be completely cured before construction (waterproof coating can be painted or sprayed several times according to the actual situation and thickness requirements of the project site, remember to finish it at one time). First, the base surface treatment

1, the base surface should be solid, smooth and clean, free of dust, oil, concrete release agent and sundries; ?

2. Scrub the oily base surface with 10% sodium hydroxide solution, and then rinse it with clean water.

3. Empty drums, loose base surfaces and sharp protrusions should be removed and repaired with polymer (DJ interface treatment agent) cement mortar.

4. It is suggested to make a fillet or fillet at the corner of Yin and Yang.

5. If there are defects or cracks in the base surface, the waterproof layer construction can be carried out only after the treatment is qualified.

1. Before the waterproof coating is applied to the dry base surface, the base surface should be wetted until there is no Mingshui. If the base surface is wet but there is no open water, it can be directly constructed.

2. First, pour the cement-based permeable crystalline waterproof slurry emulsion into the mixing barrel, then pour the powder, fully stir until it is even and paste, and then stir for 10 minutes, the effect is better.

3.？ Brush the mucilage directly on the base surface with a brush or roller brush. After the first layer is completely dried (about 2~4 hours), brush it for the second time, and the brushing directions of the two times should be staggered.

4.4. After the cement-based permeable crystalline waterproof layer is dried for about 24 hours, two cement-based permeable crystalline flexible waterproof coatings shall be painted on all corners or nozzle edges, and the lap width shall be not less than 10cm.

5.？ Intermittent stirring should be maintained during operation to prevent mucus precipitation.

6. After the waterproof layer is completely dried, mortar protective layer or other covering layer can be made on it.

Third, the construction matters needing attention

Construction is prohibited below 1.5℃ or when it rains.

2.？ If the construction is carried out in a particularly humid and ventilated environment, ventilation equipment should be used to speed up the film formation of waterproof coating, so as not to affect the quality of waterproof layer;

3.？ Never mix dry mortar with water before using it; ?

4.？ Joint treatment shall be carried out according to the requirements of relevant specifications, and it is recommended to add a layer of glass fiber mesh; ?

5.？ Within 24 hours after coating, people should be prevented from walking.

6.？ Before the completed waterproof layer is protected, there shall be no angular heavy objects, such as iron, steel nails, steel bars and scaffolding. On the waterproof layer, so as not to damage the waterproof layer; ?

7. After the waterproof layer is completely dried, other covering layers can be made;

8. This product contains cement, and people with skin allergies should take protective measures such as wearing gloves.

Note: during the waterproof construction process, even during the whole decoration process, a large amount of formaldehyde will be released in the air. Its harm is listed as the number one hazard source of indoor health, so the house should be ventilated three months after renovation. You can also put some nano-silicon nano-silicon nano-silicon nano-silicon nano-silicon nano-silicon nano-silicon nano-silicon nano-silicon nano-silicon nano-silicon nano-silicon nano-silicon nano-silicon nano-silicon nano-silicon nano-silicon.

I hope my answer can help you. First of all, you need to know where waterproof is needed. Whether it is home improvement or engineering, different parts are suitable for different waterproof materials. It is suggested that mortar waterproofing agent can be used in bathroom, kitchen and basement, and K waterproofing slurry and mortar waterproofing agent are needed for roof and balcony construction. If tooling is used, waterproofing membrane will be more commonly used in some places.

Practice process:

After cleaning up the base, the key parts such as the angle of yin and yang, expansion joints and construction joints should be treated first. Especially the parts that are not easy to paint, such as drainage holes, should be strengthened and coated with waterproof primer. Prepare waterproofing membrane, waterproof coating, base coating and adhesive membrane coating must be distinguished. Priming. In order to improve the adhesive force between the waterproofing membrane and the base, the primer can be applied repeatedly, evenly and thoroughly, and fully penetrated into the concrete base to improve the adhesive strength and shear strength. Waterproof coating must be prepared according to the product description, and the ratio is A:B=:, and the amount of preparation each time matches the actual amount on site. 4. Waterproof coating should be stirred evenly for about-minutes, and the mixture of component A and component B should be stirred evenly. The evenly mixed waterproof coating shall be painted according to the area required at the site, and the area of the base layer shall be larger than that of the bonded coiled material. The waterproof coating shall not exceed minutes at the latest from the end of mixing to the end of brushing. 6. After the first coating is completed, it takes about 4-8 hours to coat the second and third coatings again. The thickness of the first coating is. Mm, and the thickness of the second coating is about. Mm, the thickness of the third layer is about. Before applying the second coating, you must wait until the first coating is completely cured. 7. When the coiled material is bonded, the second coating should be completely cured before construction (waterproof coating can be painted or sprayed several times according to the actual situation and thickness requirements of the project site, remember to finish it at one time).

Hope to adopt, thank you 1, foundation surface treatment.
