Since the eighties, the problem of color steel roof leakage has become a very prominent problem in China's engineering construction. It directly affects the use function of the house and user safety. In order to solve the problem of color steel roof leakage, WeiYiJia carried out research work on the causes of water leakage and treatment and maintenance methods, and now launched WYJ-312 color steel renovation special polyurea waterproofing material, which can effectively prevent color steel from leakage and releasing.
High extension/water/acid/alkali salt resistance/abrasion resistance, adjustable curing time, introduction of silane monomer, improved adhesion to concrete and metal surfaces We can customize different products for different needs.
Airless sprayer spraying or scraping can be applied, regardless of curing time.
All products meet the requirements of safety and environmental protection.
- flat roofs / pitched roofs / color steel roofs / city roof renovation
Construction environment temperature is 0 ° C ~ 50 ° C. Rain, snow, wind level 5 to. Waterproof construction should not be carried out on.
The substrate should be solid, no flimsy, sandy and uneven, no open water, oil, debris.
Through the waterproof layer of the pipeline, pre-buried parts, equipment foundations, etc. should be buried and installed before the construction of waterproof layer is completed.
The water-cement ratio must not be too large, which will easily lead to water secretion on the concrete surface and reduce the concrete surface strength.
The unreasonable grading of sand and gravel, high mud content, easily lead to the ground, mortar wall sand, affecting the early hydration of cement and the concrete set.
Do not over-vibrate during the construction process, easy to intensify the concrete surface water secretion, resulting in lower concrete surface strength.
Failure to timely maintenance or inadequate maintenance, exposure to the sun or high winds lead to a large amount of water loss on the concrete surface, the surface is not fully hydrated, resulting in lower strength.
Poor control of calendering time, concrete surface does not reach a certain strength on the human work, low-temperature construction of concrete surface frost, etc..
