In life, a small number of owners don’t know much about the development of the waterproof industry, and they don’t know how to distinguish between toilet waterproof membranes and new waterproof coatings, and they are blind. Today, the editor is here to introduce to you the bathroom waterproof membrane, as well as the method of bathroom waterproof membrane and some precautions, let’s take a look.
As the non-leakage connection between the engineering foundation and the building, the toilet waterproof membrane is the first barrier for waterproofing the entire project and plays a vital role in the entire project. The main products are asphalt waterproof membrane and polymer waterproof membrane.
Basic treatment of toilet waterproof membrane:
(1) Before laying the waterproof layer, all other projects must be completed, and then the base layer should be cleaned.
(2) The base layer must be flat, firm, free of looseness, sanding, drumming, bumps and cracks. If the above phenomenon occurs, it must be repaired with cement mortar with 107 glue
(3) The base layer should be relatively dry, with a moisture content of not less than 8%.
(4) Parapets, yin and yang corners, wall pipes, expansion joints and drainage slopes should meet the design requirements.
Precautions for toilet waterproof membrane construction:
(1) The waterproof base surface (leveling layer) must be hard, smooth, dry (moisture content should not be greater than 10%) and clean, and there should be no anti-sand and various sharp objects.
(2) If there is snow, water and frost on the base surface of the operation, construction is not allowed.
(3) The toilet waterproof membrane should not be constructed under negative temperature conditions. If it must be constructed under negative temperature, measures should be taken to ensure that the waterproof layer after laying is free from cracks and poor bonding.
(4) When paving the bathroom waterproof membrane, you should always squeeze and remove the air with your hands to avoid bulges.
(5) When carrying the bathroom waterproof membrane, it should be handled with care, and it should not be thrown to avoid damage.
Due to the complicated and difficult method of waterproofing membranes for toilets, Fuwo Xiaobian still recommends that netizens use water-based waterproof coatings directly in wet parts such as kitchens and bathrooms. Mix liquid materials and powder materials evenly and paint directly, which can be operated by ordinary dripping plasterers. The construction of bathroom waterproof membrane is not only simple, the material is environmentally friendly and healthy, the cost is also favorable, and the service life is long, so that you can avoid the worries of waterproofing.
