Do you know the reasons for the failure of Profile Pvc waterproofing?

I believe everyone knows that Profile Pvc is a very good waterproof construction material that is loved by many decoration companies, but as the saying goes, if you walk by the river, how can you not get your shoes wet? Even the best will have bad cracks, and edge bead will also have a day of waterproofing failure. The editor will answer the reasons for the failure of Profile Pvc waterproofing for everyone!

1. The polyurethane waterproof coating is too thin. Waterproof layer: The polyurethane waterproof layer must have a certain thickness of waterproof effect. The polyurethane material itself is still low in water absorption. If the thickness of the layer is less than water, through the days of heavy rain, the rain passes through the bottom of the sun-resistant polyurethane water-repellent layer, and still produces steam at the bottom, causing the waterproof layer to peel off. The Glass Fiber of the adhesive is best reinforced at all corners to prevent the waterproof layer from leaking and breaking the polyurethane.

2. There is water vapor in the bottom layer: Since polyurethane waterproof coating is an oily waterproof material, it must be ensured that the ground is not dry before construction. Otherwise, after the waterproof layer is completed, the water vapor is wrapped inside and converted into strong steam under the sun, which will cause the polyurethane waterproof layer to peel off.

3. The bottom layer is not clean and the environment is clean: Because before the waterproofing project construction company, the plain ground must be cleaned, and try not to have dust and loose materials, otherwise we will cause the waterproof layer to be not firmly bonded to the base layer, leaving hidden dangers of leakage. The arch bead is based on glass fiber woven fabric and is soaked in a polymer anti-emulsion coating. It has good alkali resistance, flexibility, and high tensile strength in warp and weft directions. It can be widely used in building interior and exterior wall insulation, waterproofing, fire prevention, crack resistance, etc. Due to the special material characteristics of the Profile Pvc, the national standard pvc Beads is stronger and more durable than ordinary cloth because it has high strength and good alkali resistance. The Profile Pvc is woven with medium alkali or alkali-free glass fiber yarn and coated with alkali-resistant polymer emulsion. The application of the grid is more linked to the advertising industry, and the places involved are basically used for advertising on the walls of high-rise buildings.

4. Material inferiority: Due to the price competition between waterproof construction materials in the Chinese market, many domestic polyurethane material manufacturers in my country cut corners on waterproof engineering materials, which will reduce the physical properties of the waterproof material itself and lead to waterproof failure.

5. Lack of construction experience: Waterproof construction is best carried out by a professional waterproof construction team. You cannot go to hardware and building materials to buy some waterproof materials for painting. Before applying for waterproofing, you need to carefully judge the cause of the leak and then solve it.
