How to do the bathroom waterproof when the rough room is renovated

Plug the sewer opening of the bathroom, raise the threshold of the bathroom with cement (ten centimeters is enough for a hail stove), and then store water in the bathroom for 24 hours to see if there is any leakage.

Buy a waterproofing agent and paint it on the bathroom floor and wall.

There are three ways to do this:

1. Waterproof coatings.

Before laying any surface materials, clean the floor and walls of the bathroom and air dry. Then brush the waterproof paint again, wait until it is dry, and brush it again, the same seventy percent dry, brush it a third time. Especially the ground, be sure to brush carefully, can not miss every corner, the wall can also be brushed, it is best to brush the wall below the meter, so that it can be foolproof.

Second, the asphalt is set up on the bottom of the pot ground, clean up the sand, air dry the ground, and then melt the asphalt block, pour all the ground at the bottom of the pot, be sure to pour it carefully in place, if the wall is tiled, you can pour it along the wall below 30 cm from the ground, and dry it naturally.

3. Waterproof asphalt membrane purchase asphalt membrane, set up the pot bottom type ground, clean the ground, use a flamethrower to heat the ground, lay the membrane (must be firmly connected, between the wall and the ground, roll the membrane to the wall not less than 40 cm) and then use a flamethrower to heat, so that they are welded with the ground, especially the coil connection side to be welded well, in the heating process, all the heating must be in place, otherwise there will be a hollow drum phenomenon, the effect is not good, the above methods, Personally, I think the first method has a better effect, simple and easy construction.

There are two kinds of waterproofing, the blue wall is rigid waterproof, which will penetrate into the wall after painting, and the hardness is high, which can prevent the tiles from falling down; The green ground is flexible and waterproof, forming a soft film after brushing, with great elasticity, and the ground is not easy to leak after painting.

Bathroom waterproofing: (1) Before the waterproof treatment of the bathroom, the ground is leveled, and the slope is found in the direction of the floor drain, the slope near the door is small, the slope near the floor drain is large, and the waterproof coating is evenly applied to ensure that the ground is flat to avoid cracking in the later stage;

2) Strengthen waterproofing at the root of the pipeline, seal the root with sealing paste, use cement to smooth the feet, paint with waterproof coating, and paste glass cloth to strengthen 1 2 layers;

3) The wall surface is treated with flat light without floating ash, and the original angle or slope angle is wiped at the junction with the wall and ground, and the waterproof coating is pasted with a glass cloth reinforcement layer of 1 or 2 layers;

5) The waterproof layer of the waterproof ground should be painted 300mm wide outside the door, and the waterproof ground should be higher than the ground, and it is best to do the waterproof wall.
