Application steps

APPLICATION

Sarnarail is positioned on the fastening line of the membrane and fastened to the roof deck with approved fasteners clamping the membrane tightly to the substrate. The adjacent roll of membrane is positioned to overlap the fastened edge by 5.5" (140 mm), aligning with the overlap line marked on the membrane. Hot-air weld the two membranes with a Sarnamatic 641mc or Sarnamatic 661mc machine with a patent pending double weld kit. While pulling the welded membrane tight, install and fasten the next Sarnarail as stated above. Fastener spacing is determined by Sika technical requirements.
