BOARD-MAX ADHESIVE APPLICATION (Insulation & Coverboard)
Preparation
Product Use
All surfaces to be bonded must be clean, dry and free of any debris and smooth with no surface contamination. Broken, delaminated, wet or damaged
insulation or cover boards must be removed and replaced prior to application of Polyset Board-Max.
To dispense adhesive, point the applicator’s nozzle at the surface to be sprayed, holding it approximately 20” (50.8 cm) from the surface. Squeeze the trigger
and move hand at a speed which delivers the desired adhesive “serpentine” ribbon. Polyset
®
Board-Max adhesive is applied in a serpentine ribbon placed at a
maximum of 12”(30.48 cm) OC.
Insulation boards are to be placed based on string and tack test (1-4 minutes based on ambient conditions) and “walked-in” immediately after placement.
NOTE:
Boards that will not lay flat due to cupping, warping or crowning, or surface irregularities of the substrate, should have weights placed on the boards until
the Polyset adhesive has achieved adequate adhesion to hold the boards in place. When spraying stops for breaks, lunch or overnight turn cylinder valves off
and place used nozzle on front of gun. When spraying is to be restarted, replace nozzle with new, unused nozzle, turn cylinder valves on and perform string
and tack test.
NOTE:
Check periodically for correct board adhesion.
