Is it necessary to do the bathroom waterproofing side close to the exterior wall?

What must be done, the process of waterproofing the bathroom.

1. Brush the waterproof paint for the first time. Before construction, ensure that the construction site is clean and dry, and the waterproof coating should be coated with no omission, firmly combined with the base layer, no cracks, no bubbles, and no falling off. The coating height is consistent, and the thickness should meet the requirements of the product.

2. Brush the waterproof paint for the second time. Note the first.

First, the second waterproof coating needs to have a certain time interval, and the second time can only be carried out after the first coating is dry, and the specific time depends on the coating. If the interval is too short, the waterproof effect will be greatly reduced.

3. Lay a protective layer. In order to prevent the subsequent construction from damaging the waterproof layer, it is necessary to lay a protective layer on the surface of the waterproof coating. The protective layer should be completely covered with the waterproof layer, no omission, firmly combined with the base layer, no cracks, no bubbles, and no falling off.

Try to do all the waterproofing, if the side near the exterior wall is not waterproofed, it will be a problem with the exterior wall decoration, and it may also seep downstairs or next door. Don't let the small be the big one.

I tried my best to do it, but I didn't do a good job of waterproofing. Now the exterior walls are cracked and peeling. Ok good house ready for rent.

I think it's better to do it, don't wait for a long time to regret it, isn't Gorja three coats and one cloth, this is very good.
