Application steps

SUBSTRATE PREPARATION

Roofing membrane to receive Sarnatred-V 2.5 shall be clean and dry. Chalk lines on the deck sheet to indicate the location of walkway.   

  

Check all existing deck sheet seams that are to be covered by Sarnatred-V 2.5 with a rounded screwdriver and reweld any inconsistencies before the walkway installation.

APPLICATION

Adhered Roofs 

Apply a continuous coat of Sarnacol 2170 or Sarnacol 2170 VC membrane adhesive to the deck sheet and the back of Sarnatred-V 2.5 in accordance with the Application Instructions outlined in the membrane adhesive product data sheet. Do not apply adhesive in the areas of the deck sheet where the Sarnatred-V 2.5 will be hot-air welded. Roll Sarnatred-V 2.5 into the adhesive and press into place with a minimum 75 lb (34 kg) steel roller. Hotair weld the entire perimeter of Sarnatred-V 2.5 to the deck sheet. Check all welds with a rounded screwdriver. Reweld any inconsistencies. 

  

Mechanically Attached Roofs 

Adhering Sarnatred-V 2.5 to the deck sheet with Sarnacol 2170 or Sarnacol 2170 VC membrane adhesive as noted in Adhered Roofs is optional. Install Sarnatred-V 2.5 over the deck sheet and hot-air weld the perimeter leaving intermittent weeps as needed of unwelded Sarnatred-V 2.5 along the low side for drainage. Check all welds with a rounded screwdriver. Reweld any inconsistencies.
