If extended time is needed to finish an application, add a bit more water to reactivate the mortar up to 45 minutes after initial preparation. Please note, our pipe wrap should be purchased and applied to any plastic pipes prior to mortar application. If additional services need to be run after mortar has set, drill through existing mortar, then add new mortar to reseal pipe, cable and duct work openings.
This fire resistant mortar will not shrink or crack, and offers up to six hours of fire resistance.
