1. What is home waterproofing?
Household waterproofing refers to the leakage prevention and leakage prevention of water parts such as toilets, kitchens, pools, balconies and indoor roofs or rainy parts. At present, the main decoration in the home is waterproofing the bathroom and the kitchen.
2, the choice of household waterproof materials
1) Types of household waterproofing
At present, the waterproof materials sold on the market are mainly waterproof for coating film, flexible waterproof and rigid waterproof. The flexible waterproof mainly has two-component polymer waterproof coating, polyurethane waterproof coating and acrylic waterproof coating. Rigid waterproofing mainly consists of polymer cement waterproof mortar and two-component waterproof mortar.
2) Requirements for waterproof materials:
Environmental protection: It is the first requirement for the selection of home decoration.
Versatile: Modern household waterproofing materials have many uses such as waterproof, mildewproof and antiseptic.
Convenient construction: Since most waterproofing is entrusted to the decoration company, the construction must be simple and convenient.
3) Mistakes in waterproof material selection
- The more soft, the better.
When people talk about waterproofing, they are limited to the application of flexible materials. Even some people think that leaving the flexible material, waterproofing can't be done. In fact, this is a wrong concept.
-- Judging quality by color.
At present, some enterprises in the market have introduced colored waterproof materials after construction, and have carried out extensive publicity, but the quality of the products should be judged mainly by their technical indicators rather than color.
-- Not considered comprehensively.
The traditional waterproof coating material of the bathroom has better waterproof effect, and the flexible surface layer is waterproof, but its own strength is relatively low, the tile adhesive can not be well bonded with the waterproof layer, and the self-weight of the tile can cause the tile to fall off.
-- Do not pay attention to breathability.
Waterproof materials must not only be waterproof, but also have breathability to improve waterproofing and life.
5) Correct choice of waterproof material
No waterproof material is omnipotent. A single flexible waterproof coating or a polymer rigid waterproof mortar alone has certain drawbacks. Although the flexible waterproof coating has good extensibility after completion, it is easily damaged by artificial objects and pierces the waterproof layer to cause leakage. Polymer cement mortar overcomes the shortcomings of other organic waterproof materials and subsequent materials, which makes the waterproof layer more durable and durable, requires simple base surface, and does not need to be leveled on the base layer.
Therefore, flexible waterproofing is adopted in the structural parts such as the root of the kitchen and the bathroom and the yin and yang angles, and the selection of the flexible waterproof coating is mainly stronger than the bonding of the PVC pipe. For the façade structure, the main purpose is moisture-proof, and rigid waterproof materials can be used.
