A set of unfinished house decoration, main body renovation, water and electricity renovation, wall construction, floor operations, hard decoration and soft decoration, design style must be considered, comfort and practicality must be considered, and all things are important in all aspects. We don’t discuss which link is more important, we just want to seriously tell you how to do a comprehensive waterproofing in a rough suite to protect our decorative efforts from being wasted due to water leakage.
Unfinished suites must at least ensure that the balcony, kitchen and bathroom are waterproof. Among them, the bathroom is waterproofing is particularly important. It is best to achieve secondary waterproofing, that is, a waterproofing is made in the bathroom foundation pit, and then a waterproofing is made in the backfilling and leveling.
The perfect waterproofing solution needs to be reasonably matched and scientifically used. We must ensure that the waterproof layer is elastic and does not fear cracks or leaks, and stick firmly, and does not leak out, so that waterproofing can last for a long time and gain a home that does not leak!
Suite waterproof one: Balcony waterproof
waterproof stickers to make balcony waterproof
1. Clean the balcony base: clean the dust and garbage, repair the base surface (the root of the tube is made into arc chamfers, smooth the exposed water pipes, etc. with cement mortar ), and moisten the base surface. A flat and solid foundation surface is the foundation condition to ensure that the waterproof layer is not hollow.
Balcony base clean
Cement slurry covers exposed pipes to ensure that the base surface is flat and solid
Cement slurry covers exposed pipes to ensure that the base surface is flat and solid
Wet the base surface
2. Configure cement slurry: Configure cement slurry according to the weight ratio of cement: water = 2: 1; first add clean water, then ordinary silicate cement , soak for 15 to 20 minutes, after thoroughly soaking (no longer bubbles), pour out the excess water, stir with an electric mixer for at least 5 minutes, and it can be used in a putty shape.
Configure cement slurry
3, position and pre-lay, cut the waterproof sticker into a suitable size for laying, and dig holes at the root of the pipe, etc.
Positioning and pre-laying, cut into appropriate size
0 First hollow out at the root of the pipe
4. Wet laying waterproof stickers: Apply cement slurry on the base, tear off the protective film on the back of the waterproof sticker, apply cement slurry, and control the total thickness of the laying slurry by 1.5mm-2.5mm; it is required to be uniform and flat, without exposing the bottom, and the overlap width between the waterproof sticker and the waterproof sticker is >8cm.
First do the nodes such as yin and yang angle
Then do the plane construction
5. The waterproof sticker on the pasting needs to scrape and discharge air from the middle to both sides, so that the waterproof sticker fully sticks to the base surface, and the scraped and discharged slurry back to the edge.
After laying it, slurry and exhaust
6. Waterproof stickers are dried for 24 hours before soaking in water.
Suite waterproofing 2: Bathroom waterproofing
Waterproof paste Make bathroom Once waterproofing
Clean the foundation pit
Repair the base hole
Repair the base hole
The base hole
The base surface must be solid, flat, clean
2, the foundation pit and turn it up 30 cm to apply waterproof slurry base. Waterproof slurry configuration: pour the liquid and then add powder, stir for 3 minutes first, let stand for 2 minutes, then stir for 3 minutes, until stir evenly and let stand for 3-5 minutes before use. The waterproof slurry should be applied twice, and then the first time the surface is dry (without the material is touched by the hand).
First time apply waterproof slurry
Second time apply waterproof slurry
3, foundation pit and its upward turn 30cm apply waterproof paste, the thickness is not less than 1.5mm, so that no material is accumulated or the bottom is exposed.
Apply waterproof paste to the waterproof slurry, be careful not to miss the details of the tube roots and other parts
4. After the waterproof paste is completely dry and restored to the rubber elasticity, perform the water-closing test .Waterproof paste is a water-based material and can only be tested for water closure only after it is completely dry.
5. After draining and drying, make a layer of cement mortar protective layer 1-2mm thick, and then backfill and level.
Backfill and level, pay attention to the slope according to the drainage direction
Waterproof slurry, waterproof paste Make bathroom Secondary waterproof
After the base surface is processed, wet the base surface
2 and apply waterproof slurry on the wall and floor. The wall should be made at least 1.8 meters, and the waterproof slurry should be applied more than twice. After the first surface is dry (without the material when touching the hand), the second time is applied.
First time to apply waterproof slurry
Second time to apply waterproof slurry, it is best to apply waterproof stickers perpendicular to the first time to apply
3. After the waterproof slurry surface is dry, wet the waterproof stickers. For kitchen and bathrooms with relatively narrow and large yin and yang corners, the waterproof sticker has the characteristics of a slump and a good sticker.
paste waterproof sticker
4. Tear off the waterproof sticker isolation film and use waterproof paste to strengthen the treatment of the root of the tube.
Suite waterproofing 3: Kitchen waterproofing
waterproofing paste for kitchen waterproofing
treatment base surface, cover exposed water pipes with cement mortar, level the base surface
wet base surface
2, 1.2 meters of wall and floor, apply waterproof slurry to the base, apply twice, and apply the first time after the surface is dry.
Waterproof slurry base
3. After the waterproof slurry is dry (usually 24 hours), apply waterproof paste 30 cm on the floor and walls. The thickness of the paste should not be less than 1.5mm.
Then apply waterproof paste to
Be careful not to miss the coating and not pile up the materials
unfinished suites must ensure that the balcony, kitchen and bathroom are waterproof!
