Instructions for using Mac Wrap concrete joint waterproofing with Gear Tensioning Ratchets

(STEP 1) Sweep or brush external portion of the joint to insure foreign materials do not interfere with the direct contact between the mastic sealer and the joint to be sealed.

Align the collar directly over the joint to where the straps close over the top of the pipe.

Remove the protective plastic film, exposing the mastic side to the joint. Wrap the exposed mastic around the joint.

(STEP 2) Insert the loose strap and through slot in the take-up shaft. Push down and up on handle to apply tension. Once proper tension has been achieved push handle down to lock into position. Note: Excess strap may be cut off or tucked back into tubing.

Remove protective film from the closing flap to cover the two tensioning ratchets and straps, completing joint.

Mac Wrap equipped with high tensioning ratchets provides a positive seal on box, arch, elliptical and round pipe.
