Description

Introduction       
EPDM waterproof membrane is of high elasticity among high polymer waterproof materials and becomes a world-popular waterproofing material. Hongyuan EPDM waterproof membrane is  made from ternary ethylene-propylene rubber, which is designed for waterproofing of exposed and non-exposed applications. Hongyuan EPDM waterproof membrane production adopts the world-advanced equipment of cold feeding extrusion and continuous vulcanization technology.

Installations       
Full adhesive system       
Full adhesive system conforms to the idea of traditional installation, It is recommended for exposed waterproof construction, such as dam, bridge, swimming pool, etc.       
       
Steps: 1. adhere the EPDM membrane directly to the smooth and clean substrate like concrete deck, insulation board, etc.        
2. Adjust membrane to make sure the overlaps is no less than *0cm and wiped clean.        
3. Then, apply special adhesive evenly to both the substrate and the membrane laps or seam tape.        
4. After minutes, press it securely and finish with sealant.       
       
Border adhesive system       
Border adhesive system is specially designed for underground and roofs which have wide, flat roof decks and bear heavy loads like accessible roof, planting roof, inversion roof. It is also economical and easy to install.       
       
Steps: 1. Spreading the waterproof membrane over the substrate.        
2. All membrane laps should at least be *0cm and should be wiped clean.        
3. Splice all membrane laps and edges with Hongyuan adhesive or seam tape.        
4. Finish with sealant.       
       
Mechanical fastened system       
Mechanical fastened system combines sound and durable quality with simple and easy installation. It is environment friendly since it does not use much organic solvent. It is cost-efficient and suitable for large projects.       
       
Steps: 1. Loosely lay the EPDM membrane on top of concrete roof deck or insulation board.         
2. Then, fix it with Hongyuan fastener.         
3. All membrane laps should be at least *0 cm and should be wiped clean.         
4. Splice all membrane laps with Hongyuan adhesive or seam tape.         
5. Finish with sealant       
       
Attentions       
■ Storage: EPDM material should be stored in well-ventilated place and avoid being exposed to the sun or rain. It  only can be put horizontally in five-level, avoiding acid, alkali, oil and organic solvents.       
■ Substrate treatment: substrate should be firm, smooth, clean and dryness (moisture content ≤9%), no dust pollution.       
■ Do not install in raining, snowy and category five or above wind days.
