The sand paddle for waterproofing in the kitchen and bathroom is still good for membrane

Bathroom, kitchen, balcony with waterproof coating, membrane first of all the base surface is required to be clean, otherwise it is easy to lose the waterproof effect due to puncture during construction (moisture content is not more than 9%), otherwise it will form the "two skins" phenomenon of separation between the base surface and the waterproof layer. The bathroom and kitchen are damp, and the construction sequence is backfilled. Mortar leveling, waterproofing, tiling, workers will carry out waterproof construction after the mortar layer solidifies, and the moisture content of the coating construction base is not more than 9%, and no matter how good the material is, the effect will be discounted.

Bathroom, kitchen, balcony using mortar waterproofing agent (suitable for the use of advanced fatty acid mortar waterproofing agent) the base surface requires to clean up the debris, can be constructed on the wet base surface, and because it must be mixed with cement mortar for waterproof construction, and the material of the mortar leveling layer is the same, the waterproof layer and the base surface have a high degree of integration. After the waterproof layer is set up and the construction method is standardized, there is no need to use other waterproof materials together, stirring cement and sand with waterproofing agent in strict accordance with the construction standards can exceed the durability of the national first-class waterproofing, sprinkling water to make the base surface wet, but there shall be no water accumulation, 24 hours after the waterproof mortar layer solidifies, first do the closed water experiment, and then paste the tile.

There is no need to make waterproofing in the kitchen.

Bathroom waterproof layer: rigid waterproof layer refers to the waterproof cement mortar with waterproofing agent, which is required by the ground structure, and it has the function of leveling layer.

On top of the rigid waterproof layer, an elastic waterproof layer (acrylic acid waterproof coating) should be made, and a protective layer of cement mortar should be made.

Now it is rare to use membrane waterproofing process at home.

Waterproofing of household bathrooms is now mostly used with waterproof coating film, that is, coatings.

If it is a foundation surface construction, it must be a good mortar, and if it is done on the floor tiles, it is good to use plastic steel mud with waterproof liquid.

It is recommended that you see the housing doctor, which is what our landlords used to use.
