How many times do you need to make the toilet waterproof?

First of all, the general bathroom should be done 2 times when doing waterproofing, that is, it should be done once before backfilling, and then again after backfilling!

So, every time I do waterproofing, how many times do I have to brush it to be qualified?

First of all, let's talk about the Lauyal mortar waterproofing agent:

It is necessary to brush the plain mortar layer (cement + waterproofing agent) first, horizontally and vertically, and brush 1 time each.

Note: The purpose of the brushing mortar layer is to make the base surface and the waterproof layer firmly bonded, without delamination and without falling.

The plain mortar is just not sticky (about half an hour), and then the mortar layer (waterproofing agent + cement + sand) is smeared.

Note: The thickness of the mortar layer determines the life of the waterproof, here is the plastering mortar layer, not a very thin brush brush; After construction, the ground thickness of the plain mortar + mortar layer is 20mm, and the wall thickness is 10mm.

After the mortar is completely dry, the closed water test can be done.

That is to say, the complete standard construction of a mortar waterproofing agent requires 2 times of plain mortar and 1 time of plastering mortar layer.

Generally, the bathroom should be done 2 times when doing waterproofing, once before backfilling, and again after backfilling!
