TJ-789 TPO Waterproof Membrane
TPO Waterproof Membrane takes TPO elastomer as base material,adding fire retardant filling,anti weathering pigment filling,anti oxidization agent and light stabilizer,through high speed mix,melting extrusion,and calendering into waterproofing sheet material. Firstly developed in the early 20 centuries,it is extensively used for rooftop waterproofing projects under the installation of mechanical fasteners. With the combination of the great anti-weathering of EPDM and the weldability of PVC sheet,it defines the leading position in waterproofing industry
TPO waterproof membrane has 0% plasticizer and no chloride,generating zero harmful gas when welding
Application: Extensively used for the waterproof projects of industrial and residential buildings and public constructions

Installation Guide
1. Substrate Requirements: Clean,no bugle and pointy object
2.Installation Steps(Mechanical Fastener)
Substrate Clean Pave PE film Pave Insulation board Pre-applied TPO Mechanical Fasten TPO Hot air Welding TPO Detailed Spots Strengthening Test Check
3. Installation
1) Clean the litters,dust on the substrate
2)Pave a layer of PE film,the overlap uses butyl adhesive tape to glue
3)Pave Extruded polystyrene foam insulation board(XPS),using exclusive fasteners to fasten the board
4)Pre-applied TPO membrane: Lay the TPO membrane on the insulation board in accordance with the snap line,paving direction should be perpendicular with the wave of profiled steel sheet,dispose the loose TOP membrane as the outline on the insulation board. Membrane remains flat and even,overlap is 12cm and appropriate trim is needed
5)Fasten the TPO membrane: Align edge of mark line 30mm install the fasteners and elastics
6)Membrane Overlap: One piece membrane laid on the other,use the automatic hot air welding machine to weld
7) Detailed Spots Strengthening: Trim adequate TPO membrane for detailed spots,use portable hot welding machine weld on the TPO membrane
8)TPO membrane edge treatment: Use batten to fasten the edge along with sealants
