When the renovation is carried out: The wall and floor waterproof construction process has to understand
In the renovation of the wall, the ground waterproof construction process have to understand, it is an indispensable part of the decoration construction. Especially in kitchens and bathrooms, the constant use of water causes the kitchen and the bathroom to be in a wet state, which is why the kitchen and the bathroom must be protected against moisture, moisture, and water. Then the wall and floor waterproof construction process must understand, in the decoration this piece is the place where the owner pays most attention, the following will fully introduce the next wall, ground waterproof construction process, the owner in the supervision process to understand the operation of the construction staff Is it correct to avoid a series of disputes in the future?

Wall, floor waterproof construction process: wall, ground floor treatment → brush cement slurry → wipe the bottom mortar → brush cement slurry → wipe surface mortar → brush cement mortar → curing.
1, grassroots processing
(1) Concrete walls with honeycomb and loose concrete should be removed, rinsed with water, then smoothed with 1:3 cement mortar or tamped with 1:2 cement mortar. The surface oil is scrubbed with a 10% aqueous solution of caustic soda and the surface of the concrete should be cut.
(2) When wiping the waterproof layer on a brick wall, it must be slit when laying bricks, and the depth is 10-12mm. Through the wall embedded pipe exposed base, cut into a 20 ~ 30mm wide, 50 ~ 60mm deep groove, with 1:2 dry hard cement mortar tamping. Pipe through the wall should be designed to do a good job of waterproofing, and apply for hidden inspection procedures.
2, the concrete wall wipe cement mortar waterproof layer
(1) Brush cement paste: mix ratio: cement: water: waterproof oil = 1:0.8:0.025 (weight ratio), mix the cement and water first, then add waterproof oil, mix well, and then use soft brush The base surface is painted evenly, and the underlying waterproof mortar is then wiped.
(2) For the bottom mortar, use 1:2.5 cement mortar and add 3% to 5% of waterproof powder to the cement. The water-cement ratio is 0.6 to 0.65, and the consistency is 7 to 8cm. Mix the waterproof powder, cement, and sand first and then mix with water. After the mixing, the plastering operation is performed. The thickness of the bottom plaster is 5 to 10 mm, and the broom is used to sweep the hair before the ash is solidified. The mortar should be used with the mix. The time for mixing and using mortar should not exceed 60min, and overnight mortar is strictly prohibited.
(3) Brush cement slurry: After the bottom ash is wiped, the cement slurry is brushed at room temperature for 1 day, and the mixing ratio and practice are the same as those for the first layer.
(4) Plastering the mortar: After brushing the pulp, the surface layer is immediately followed by the mortar. The thickness of the plaster is approximately 5 to 10mm. Before the solidification, the wooden trowel must be used to flatten the surface. Press with an iron trowel. Light.
(5) Brush cement slurry: After the surface layer is wiped, the cement slurry is brushed for 1d. The mixing ratio is cement:water:waterproof oil = 1:1:0.03 (weight ratio). The method is the same as the first layer.
3, brick wall wipe cement mortar waterproof layer
(1) Grassroots watering and wetting: The brick wall is thoroughly drenched with a water pipe the day before plastering, and the brick wall is then sprinkled with water to wet the next day.
(2) Wipe the bottom mortar: mix ratio is cement: sand = 1:2.5, add 3% of the cement weight of the waterproof powder. First, scrape a thin layer with an iron trowel, and then use a wooden trowel to apply the ash to the surface and smooth it. Plaster thickness of about 6 ~ 10mm.
(3) Wipe the cement slurry: 1 ~ 2d after the bottom layer is wiped, wet the surface with water, then wipe the cement waterproof slurry, and mix the cement with 3% waterproof powder. First mix the cement with the waterproof powder, then add the appropriate amount of water and mix it evenly. Wipe it thinly with an iron trowel, and the thickness is about 1mm.
(4) Plastering the mortar: After wiping cement paste, apply the mortar with the same proportion as that of the bottom layer. Use a wooden trowel to flatten it, and then compact and calender it with an iron trowel. Plaster thickness between 6 ~ 8mm.
(5) Brush cement paste: After plastering the surface for 1d, brush the cement paste, the mixture ratio is cement:water:waterproof oil = 1:1:0.03 (by weight). The method is to mix the cement and water firstly. Add water-repellent oil and stir evenly. Brush the surface evenly with a soft-bristled brush.
4, the floor wipe cement mortar waterproof layer
(1) Cleaning up the base layer: Clean the loose concrete and mortar on the cushion, and remove the protruding bulge.
(2) Brush cement paste: mix ratio: cement: water-repellent oil = 1:0.03 (weight ratio), add appropriate amount of water to synthesize porridge, spread on the ground, and sweep it evenly with a broom.
(3) Wiping the bottom mortar: The bottom layer is made of 1:3 cement mortar and mixed with 3%~5% waterproof powder. The mixed mortar was poured on the ground, and it was scraped with a ruler. The wooden trowel was flat and the iron trowel pressed it again.
(4) Brush cement paste: After brushing cement paste for 1 day at room temperature, the mix ratio is cement: water-repellent oil = 1:0.03 (weight ratio) plus proper amount of water.
(5) Wiping layer mortar: After brushing cement slurry, then wipe the surface layer mortar, mixing ratio and practice with the bottom layer.
(6) Brush cement slurry: After the initial setting of the surface mortar, brush the final pulp (not too thin to meet the requirements of abrasion resistance), and the ratio is cement:waterproof oil = 1:0.01 (weight ratio), plus appropriate amount The water is tightly integrated with the surface mortar and pressed and compacted.
(7) Maintenance: After the ground has a certain strength, the surface covered sacks or straw bags are often watered and moistened. The curing time is determined by the temperature conditions, generally 7 days, and the slag portland cement should not be less than 14 days. Water pressure effect. Winter conservation temperature should not be lower than +5°C.
5, plastering procedures, access and yin and yang practice
Plastering procedures, generally wipe the wall after wiping the ground. Scorpions should not be thrown at the yin and yang corners. Each layer of plastering spatula should not be left on a line. The bottom layer and the surface layer of the pagoda should be between 15 and 20 cm. All the wall's inside corners have to be radiused with a radius of 50mm, and the corners are rounded with a radius of 10mm. The overcast angle on the ground must be rounded to more than 50mm, and then lighted and compacted with a female angle trowel.
The total thickness of the fifth floor is controlled around 20mm. Multi-layer practices should be continuous construction, all layers closely combined, leaving no or a lot of construction joints, such as must be left when leaving a ladder, then follow the order to operate in accordance with the hierarchy, the layers overlap tightly, the joints are required to leave the position The inside corner is 200mm.
Ground waterproof construction precautions:
1, plastering shelf to leave the wall 15cm. When breaking the shelf, you must not touch the mouth and the wall.
2. Floor ash should be cleared up and used in time, so that you can live and work hard.
3, people on the ground can not be too early.
The prone to quality problems in ground waterproof construction:
1. Empty drums and cracks: The base layer was not well treated, and the surface of the concrete before brushing the pulp slurry was not cut. The oil stain was not cleaned with ash, resulting in empty drums and cracks. In addition, poor conservation and inadequate maintenance period are also one of the reasons.
2. Leakage: The plastering time of each layer is not properly mastered, and it is too tight to fall. The pulp is too dry, and the screed mortar is not easily bonded to cause water seepage. The detailed handling of the wall-to-wall and wall-pass pipes is not easy to handle, and it can easily cause partial leakage. During the construction, it must be carefully handled according to regulations.
