Ask for a high finger to point to how to waterproof the bathroom

First of all, you need to deal with the drain and floor drain, you can use silicone paint and cement 1:2 water blending and brushing, and then use silicone waterproof paint to paint two or three ways, each time before painting must be carried out on the basis of the previous drying, the façade must be turned up at least 30 cm, detailed information can be found on our website.

Plugging with cement alone is not effective, and the junction of old and new cement is the most prone to cracks.

If you don't have JS composite waterproof coating, then you should at least stick some fiberglass cloth to the joint, the purpose of sticking fiberglass cloth is to prevent cracks.

If there is a JS composite waterproof coating, it is easier to do. First treat the base surface flat, and when there is no open water on the surface, use JS with cement, or plugging king, or nothing to match, the base of the entire bathroom is brushed over (the base refers to the cast-in-place board), if you have not dug that position before, then you only need to deal with the vicinity of the pipe.

However, it is best to dig the cast-in-place slab near the pipeline, level it first, and then brush it several times with the JS ingredients mentioned above, especially around the pipeline, and the façade of the wall should also be done.

In fact, to do waterproofing, you must first think about the structure of the bathroom to see where it is possible to leak. The bottom of the bathroom is a cast-in-place slab, the top is a waterproof layer, a concrete layer, and the top is a tile. The cast-in-place board will generally not have a problem, and if it cracks, it is best to do a waterproof as a whole.

If it is just the usual decoration, or pipe laying, because it will destroy the original waterproof layer, it needs to be dealt with near the place where you have damaged, which is equivalent to repairing the leakage.

1.First, use mortar to repair the gaps and excavations

2。Then use mortar waterproofing agent to do waterproofing.

3.Specific methods of waterproof construction of toilets:

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

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

1) Mix "Laoyal" with cement 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, mix it with "Laoyal" with cement and sand to form a waterproof mortar, and wipe it on the surface of the waterproof plain ash with a thickness of 8 mm.

3) After the waterproof mortar layer is solidified within 24 hours, it is sprinkled with water for curing.

C.Ground: The total thickness of the waterproof layer (waterproof mortar + waterproof mortar) is not less than 20 mm.

1) Mix "Laoyal" with cement 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 of waterproof mortar, mix it with "Laoyal" with cement and sand to make a waterproof mortar and wipe it on the surface of the waterproof mortar, with a thickness of 18 mm.

3) After 24 hours of waterproof mortar solidification, sprinkle water for curing.

D.Closed water test: Plug all the drains in the bathroom, build a 250 mm high "threshold" at the door, and fill it with 200 mm high water. After 24-72 hours, it is confirmed that there is no leakage and the tiles can be laid.

SBS bar, or polyurethane waterproof, somewhat elastic, just cement mixed with impermeable agent is useless, and there are seams on the joint surface of the old and new.

Make pipe hoops around the pipes to prevent backfilling.

I can't figure out why you're smashing the bathroom floor? Anyway, it's going to be bricked, and it's going to be under the brick.

Of course, the holes, gaps, and grooves should be repaired and smoothed with cement. Do waterproofing again.
