JOINT SEAL INSTRUCTIONS
The following information covering surface preparation applies to all sealed joints whether
sealer Z11 or strip sealer Z12 and/or Z13 is being used. The typical joint sealing details shown
on this page may be referenced throughout this manual or other optional equipment
installation drawings. Years of experience has shown the instructions on surface preparation
and sealing details do result in watertight joints. Inadequate attention to the details will result in
joints that leak. Do not apply either sealer if temperature is below 40 degrees Fahrenheit (5
degrees Celsius).
All flanges are to be straight. Rework kinks or bends that exist. Clean surfaces being sealed
solvent. If cloth is used, it must always be clean and dry. Exercise caution in using solvents,
always read labels and instructions. Care should be taken not to wipe dirt or oil onto the
cleaned surface from adjacent uncleaned area. Mating surfaces to be sealed must be kept
clean and dry prior to assembly. No water, grease or dirt should contaminate cleaned area.
Note that stainless steel requires a larger area to be cleaned because oil will contaminate
surfaces quickly. Oil will migrate through punched holes and around sheared edges.
Application instructions for Tube Sealer Z11 (Type A, B, & C seals):
Tube sealer, Find# Z11, cones in a 1/12 gallon (315ml) cartridge and is applied using a
standard caulking gun. Apply sealer to unassembled parts. Care should be taken to fill voids
and gaps at joints. After parts have been assembled, trowel excess sealant over joint, taking
care to force sealant back into joint, not out of joint. Do not use solvent to aid in applying
sealer. Solvent adversely affects bonding of sealant to metal. Care should be taken to avoid
leaving holes, or bubbles in sealant. Do not subject sealed joints to waterloading for 48 hours
at temperatures of 70 degrees Fahrenheit (21 degrees Celsius) and above. Lower
temperatures will require a longer cure time.
Application Instructions for Strip Sealer Z12 & Z13 (Type D, E, F & G seals):
Strip sealer is supplied an 1/2" (13mm) Z13 and 1" (25mm) Z12 widths. It is intended that the
1/2" (13mm) wide sealer be used unless otherwise noted. Apply continuous pieces of strip
sealer to the unassembled parts. Do not splice pieces except when turning a corner. Cut with
a sharp knife, do not stretch, or tear. Gaps at joints and corners can be filled by spanning a
piece of strip sealer to gain the proper thickness. Then work it into the joint to fill gaps and
greate an even surface. After parts are set together, use a drift pin, or other pointed object, to
puncture sealer at each fastener hole where required.
