experience. Apply primer to comply with joint-sealant manufacturer's written instructions.
Confine primers to areas of joint-sealant bond; do not allow spillage or migration onto adjoining
surfaces.
3.3 JOINT DESIGN
A. Sealant depth is measured at the center (thin) section of sealant bead.
B. Install sealants to depths and widths as recommended by sealant manufacturer and as shown on
the drawings. Also, conform to the following general limitations if not in conflict with sealant
manufacturer’s recommendations.
1. For sidewalks, pavements and similar joints subject to traffic and other abrasion and
indentation exposures, fill joints to a depth equal to 75% of joint width, but neither more
than 5/8 inch deep nor less than 3/8 inch deep.
2. For normal moving joints not subject to traffic, fill joints to a depth equal to 50% of joint
width, but neither more than 5/8 inch deep nor less than ¼ inch deep.
3. Depth of sealant must not exceed width of joint.
4. Sealant joints shall not be less than ¼ inch in width and ¼ inch in depth.
5. Sealant joints shall not exceed 2 inches in width in a single application.
3.4 SURFACE PREPARATION

surfaces shall be free of any old sealant, contaminants and impurities which are deleterious to
bonding or adhesion of primers or sealant.
B. Clean ferrous metals of all rust, mill scale and coatings by wire brush or grinding. Any
equipment used to remove rust shall be free of oil contaminants.
C. Wire brush masonry joint surfaces, then blow clean with oil free compressed air.
D. Apply primer per manufacturer’s recommendations. Allow primer to dry prior to applying
sealant.
E. Do not caulk joints until they are clean, dry, and free of dust, loose mortar, old sealant, foreign
matter or other bond inhibiting materials, and in compliance with requirements of manufacturer
of materials, details shown on drawings, and specific requirements of other sections of
specifications.
3.5 JOINT BACKING

C. Where shown on drawings where depth of joint will not permit use of joint backing, or
wherever recommended by sealant manufacturer, install bond-breaker tape to prevent three-
sided adhesion.
D. Do not leave voids or gaps between ends of joint backing units.
3.6 APPLICATION/INSTALLATION OF JOINT SEALANT
A. Apply sealants neatly, in a good and workmanlike manner which meets following minimum
requirements or standards. Specific instructions of manufacturer must also be followed.
B. Apply sealant using a gun with proper size nozzles. Use sufficient pressure to fill all voids and
joints solid to backup material, with complete wetting of all joint bond surfaces.
C. Applied sealant shall form a full, smooth, uniform bead, free of ridges, wrinkles, sags, air
pockets and embedded impurities.
D. After joint has been completely filled with sealant, neatly tool joint sealant to eliminate air
pockets or voids, and to provide a smooth, slightly concave, neat appearing finish, with sealant
surface slightly below adjoining surfaces. Wetting of finished surface will not be allowed.
E. Where horizontal joints are located between a horizontal surface and vertical surface, fill joint
to form a slight cove, so joint will not trap moisture and dirt.
F. Protect adjacent surfaces and systems from sealant material. Use masking tape where required
to prevent contact of sealant with adjoining surfaces which otherwise would be permanently
stained or damaged by such contact or by cleaning methods required to remove sealant smears.
Remove tape immediately after tooling without disturbing joint seal.
G. Sealant Installation Standard: Comply with recommendations in ASTM C 1193 for use of joint
sealants as applicable to materials, applications, and conditions indicated.
H. Tooling of Non-Sag Sealants: Immediately after sealant application and before skinning or
curing begins, tool sealants according to requirements specified below to form smooth, uniform
beads of configuration indicated; to eliminate air pockets; and to ensure contact and adhesion of
sealant with sides of joint.
1. Remove excess sealants from surfaces adjacent to joint.
2. Use tooling agents that are approved in writing by joint-sealant manufacturer and that do
not discolor sealants or adjacent surfaces.
I. Provide joint configuration to comply with joint-sealant manufacturer's written instructions,
unless otherwise indicated.
J. Provide recessed joint configuration for silicone sealants of recess depth and at locations
indicated.

3.7 CLEANING
A. Clean off excess sealants or sealant smears adjacent to joints as the Work progresses by
methods and with cleaning materials approved by manufacturers of joint sealants and of
products in which joints occur.
3.8 PROTECTION
A. Protect joint sealants during and after curing period from contact with contaminating substances
and from damage resulting from construction operations or other causes so sealants are without
deterioration or damage at time of Substantial Completion. If, despite such protection, damage
or deterioration occurs, cut out and remove damaged or deteriorated joint sealants immediately
and replace with joint sealant so installations with repaired areas are indistinguishable from the
original work.
3.9 JOB SITE CLEAN-UP
A. Sealant applicator must remove all excess materials from job site.
B. Leave all surrounding areas where joint sealant has been applied free of excess sealant, debris
and foreign substances.
