<br />2.4 JOINT -SEALANT BACKING
<br />A. General: Provide sealant backings of material and type that are nonstaining; are compatible with joint substrates, sealants, prim-
<br />ers, and other joint fillers; and are approved for applications indicated by sealant manufacturer based on field experience and
<br />laboratory testing.
<br />B. Cylindrical Sealant Backings: ASTM C 1330, of size and density to control sealant depth and otherwise contribute to producing
<br />optimum sealant performance:
<br />1. Type: C (closed -cell material with a surface skin).
<br />C. Bond -Breaker Tape: Polyethylene tape or other plastic tape recommended by sealant manufacturer for preventing sealant from
<br />adhering to rigid, inflexible joint -filler materials or joint surfaces at back of joint where such adhesion would result in sealant
<br />failure. Provide self-adhesive tape where applicable.
<br />2.5 MISCELLANEOUS MATERIALS
<br />A. Primer: Material recommended by joint sealant manufacturer where required for adhesion of sealant to joint substrates indi-
<br />cated, as determined from preconstruction joint -sealant -substrate tests and field tests.
<br />B. Cleaners for Nonporous Surfaces: Chemical cleaners acceptable to manufacturers of sealants and sealant backing materials, free
<br />of oily residues or other substances capable of staining or harming joint substrates and adjacent nonporous surfaces in any way,
<br />and formulated to promote optimum adhesion of sealants with joint substrates.
<br />C. Masking Tape: Nonstaining, nonabsorbent material compatible with joint sealants and surfaces adjacent to joints.
<br />PART 3 - EXECUTION
<br />3.1 INSTALLATION
<br />A. Contractor performing work must be one the Sealant Manufacturer's Approved Applicators.
<br />B. Surface Cleaning of Joints: Clean out joints immediately before installing joint sealants.
<br />1. Remove foreign material from joint substrates that could interfere with adhesion of joint sealant.
<br />2. Clean porous joint substrate surfaces by brushing, grinding, blast cleaning, mechanical abrading, or a combination of these
<br />methods to produce a clean, sound substrate capable of developing optimum bond with joint sealants. Remove loose par-
<br />ticles remaining from above cleaning operations by vacuuming or blowing out joints with oil -free compressed air.
<br />3. Remove laitance and form -release agents from concrete.
<br />4. Clean nonporous surfaces with chemical cleaners or other means that do not stain, harm substrates, or leave residues could
<br />interfere with adhesion of joint sealants.
<br />. , _ 5, _ All surfaces,to„b, e, caulked shall be clean and dry.
<br />C. Joint Priming: Prime joint substrates where recommended in writing by joint sealant manufacturer, based on preconstruction
<br />joint -sealant -substrate tests or prior experience. Confine primers to areas of joint -sealant bond; do not allow spillage or migra-
<br />tion onto adjoining surfaces.
<br />D. Masking Tape: Use masking tape where required to prevent contact of sealant with adjoining surfaces that otherwise would
<br />be permanently stained or damaged by such contact or by cleaning methods required to remove sealant smears. Remove tape
<br />immediately after tooling without disturbing joint seal.
<br />E. Sealant Installation: Comply with recommendations in ASTM C 1193 for use of joint sealants as applicable to materials, appli-
<br />cations, and conditions indicated.
<br />F. Install sealant backings to support sealants during application and at position required to produce optimum sealant movement
<br />capability.
<br />1. Do not leave gaps between ends of sealant backings.
<br />2. Do not stretch, twist, puncture, or tear sealant backings.
<br />3. Remove absorbent sealant backings that have become wet before sealant application and replace them with dry materials.
<br />G. Install bond -breaker tape behind sealants where sealant backings are not used between sealants and back of joints.
<br />p g J
<br />H. Place sealants so they directly contact and fully wet joint substrates.
<br />1. Completely fill recesses provided for each joint configuration.
<br />2. Produce uniform, cross -sectional shapes and depths that allow optimum sealant movement capability.
<br />3. All deep cracks shall be filled to within 1/2 inch of the surface with an appropriate back-up material and caulked with a
<br />caulking gun. Caulking beads shall be smooth and straight.
<br />4. Caulk around all door and storefront openings and where noted on the drawings.
<br />1. Masonry control joints shall be caulked with a high -quality paintable urethane caulk. Control depth of caulk at 3/8 inch to 1/2 inch
<br />with a continuous closed -cell rod.
<br />J. Tooling of Nonsag Sealants: Immediately after sealant application and before skinning or curing begins, tool sealants to form
<br />smooth, uniform beads, to eliminate air pockets, and to ensure contact and adhesion of sealant with sides of joint.
<br />1. Remove excess sealants from surfaces adjacent to joint.
<br />2. Use tooling agents that are approved by sealant manufacturer and that do not discolor sealants or adjacent surfaces.
<br />3. Joint Configuration: Concave joint configuration per Figure 5A in ASTM C 1193, unless otherwise indicated.
<br />K. Clean excess sealants or sealant smears adjacent to joints as installation progresses by methods and with cleaning materials
<br />approved in writing by manufacturers of joint sealants and of products in which joints occur.
<br />L. Through -Penetration Firestop Installation:
<br />1. General: Installation through -penetration systems to comply with "Performance Requirements" of the firestop system
<br />manufacturer's written installation instructions and published drawings for the applications indicated.
