Yes, the two products can be used in conjunction with each other, provided the joints are fully adhered.
Shur-Gard MU Ultra HT should only be installed when material interface temperatures are 40ºF and rising. Lower temperatures will result in lower tack and will reduce adhesion.
If low temperatures are present during installation, the underlayments may be back nailed to hold them in position during installation. As temperatures rise, the adhesive will activate and bond with the substrate and seams.
Priming is not necessary when adhering the underlayments to clean, dry roof decks made of wood. Concrete and masonry deck surfaces require priming with asphalt primer that meets ASTM D41 standards.
Rolls of Shur-Gard MU Ultra HT should be stored in their factory-applied packaging in a dry, protected warehouse at a temperature not exceeding 110ºF.
