Most of the waterproofing that construction companies and developers do before housing delivery is waterproofing of coils. This kind of waterproof material has low cost, low adhesion, easy layering with cement, etc. The service life is relatively short: waterproofing of the coating film type. Materials are waterproof materials that have been used in more recent years and are roughly divided into two types, one is water-based and the other is oil-based.
Water-based use is more convenient, but the waterproof effect is not as good as they say. The oily water-repellent effect is good, but there is a certain odor during construction, and the cement is not very well combined and the price is high. It is recommended that households use water-repellent materials such as paint films. Currently, waterproof materials such as Switzerland's Sika Waterproof and Germany's Henkel Waterproof are more effective. Sika Waterproof is a cement-based waterproof film that is divided into flexible and rigid. The waterproof effect is better, and the construction operation is convenient. Henkel's waterproof is polyurethane, and the effect is also very good, but the construction is a certain smell.
Toilet waterproof practices:
The place of ordinary residential toilets is small, and there are pipelines and floor boards, etc. Therefore, the paint is often used for waterproofing but rarely for waterproofing.
There are two kinds of paint waterproof:
Synthetic Polymers - Polyurethane Waterproof Coating (Polyester Cloth, Fiberglass Cloth, Etc.)
Polymer modified asphalt--SBS waterproof coating (carcass reinforced polyester cloth, fiberglass cloth, etc.)
The asphalt-based waterproof coating is basically not used.
