300 VOC Foamboard

applying 3/16" bead of adhesive with lines
6-12" apart (follow adhesive manufacturers'

the adhesive cures.
It is suggested that a bead of waterproof
sealant be applied to the top edge of the
FOAMULAR

where the boards join each other in order to
retard water penetration to the foundation

adhesive is applied.
All seams between boards should be butted
tightly. Taping of seams not required.
