Storage
SBS-PYPE material should be stored in well-ventilated shade place and protected from sun or rain. The temperature in stored places can not be higher than 50° C. It only can be put vertically in single-level. The normal shelf life is 1 year.
Transportation
SBS-PYPE material can not be inclination or lateral drift. Cover with cloth when it is necessary.
Application System
Yuhong modified bitumen membrane waterproof system includes substrate, undercoat, membrane waterproof layer, protection and isolation layer.
Yuhong also provide a complete line of compatible accessories and components, including primers, adhesives for membrane, pipe clamps, terminal battens and screws.
Application Method
Surface preparation
Surfaces should be dry, clean, smooth and free from any dusts, oil or loose particles. Cracks and surface irregularities need to be filled by polymer mortar.
Priming
Before membrane laying, substrate treating agent need to be brushed evenly and completely cover all laying places.
Membrane Laying
For adhesion between membrane and substrate or membranes, it can use hot melt method or cold adhesion method. According to application designs and specific applied parts, it can be applied by fully adhered method, strip adhered method and border adhered method.
Sealing, fixing and constraining on vertical surfaces
On vertical surfaces, fix with metal battens and seal with sealants for membranes.
Application on protection and isolation layer
After membrane laying, apply on protection and isolation layer according to waterproof layer design.
