5. INSTALLATION
Preparation
Joint Preparation
1. The product may be used in sealant joints designed in
accordance with SWR Institute's Sealants - The
Professional's Guide.
2. In optimal conditions, the depth of the sealant should be ½
the width of the joint. The sealant joint depth (measured at
the center) should always fall between the maximum depth of
½" and the minimum depth of ¼". Refer to Table 1.
3. In deep joints, the sealant depth must be controlled by closed
cell backer rod or soft backer rod. Where the joint depth does
not permit the use of backer rod, a bond breaker
(polyethylene strip) must be used to prevent three-point
bonding.
4. To maintain the recommended sealant depth, install backer
rod by compressing and rolling it into the joint channel
without stretching it lengthwise. Closed cell backer rod
should be about ⅛” (3 mm) larger in diameter than the width
of the joint to allow for compression. Soft backer rod should
be approximately 25% larger in diameter than the joint width.
The sealant does not adhere to it, and no separate bond the
backer-rod.
Surface Preparation
Substrates must be structurally sound, fully cured, dry, and
clean. Substrates should always be free of the following: dirt,
loose particles, oil, grease, asphalt, tar, paint, wax, rust,
waterproofing or curing and parting compounds, membrane
materials and sealant residue.
CONCRETE, STONE, and other MASONRY
Clean by grinding, sandblasting or wire brushing to expose a
sound surface free of contamination and laitance.
WOOD
New and weathered wood must be clean, dry and sound. Scrape
away loose paint to bare wood. Any coatings on wood must be
tested to verify adhesion of sealant or to determine an
appropriate primer.
