PART 3-EXECUTION 


A. Acceptance of Surfaces and Conditions: Examine substrates to receive joint sealants and 

associated Work to which joint sealants will be applied for compliance with requirements and 

other conditions affecting performance. Proceed only when unsatisfactory conditions have been 

corrected in a manner complying with Contract Documents. Starting Work within a particular 

area will be construed as acceptance of surface conditions. 


A. Cleaning of Joints: Clean out joints immediately before installing joint backings and sealants to 

comply with joint sealant manufacturer's written instructions and following requirements: 

1. Remove foreign material that could interfere with adhesion of joint sealant, including, but 

not limited to, dust, paints (except for permanent, protective coatings tested and approved 

for sealant adhesion and compatibility by sealant manufacturer), old joint sealants, oil, 

grease, waterproofing, water repellents, water, surface dirt, and frost. 

2. Clean porous joint substrate surfaces by brushing, grinding, mechanical abrading, or a 

combination of these methods to produce a clean, sound substrate capable of developing 

optimum bond with joint sealants. Remove loose particles remaining after cleaning 

operations above by vacuuming or blowing out joints with oil-free compressed air. 

3. Remove laitance and form-release agents from concrete. 

4. Clean non-porous joint substrate surfaces with chemical cleaners or other means that do 

not stain, harm substrates, or leave residues capable of interfering with adhesion of joint 

sealants. 

B. Joint Priming: Prime joint substrates where recommended by joint sealant manufacturer, or as 

indicated by prior experience, or as required by pre-construction compatibility and adhesion 

testing. 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. 

C. Masking Tape: Use masking tape where required to prevent contact of sealant or primer with 

adjoining surfaces that 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. 


A. Installation Quality Standards: In addition to standards listed elsewhere, perform Work 


1. ASTM C 1193 for use of joint sealants as applicable to materials, applications, conditions 

indicated, and following profile configurations: 

a. Fillet: Figure 5. 

b. Bridge: Figure 6. 

c. Butt: Figure 8A (concave tooling), generally hour-glass shape with 2:1 width-todepth 

ratio. 



2. Substrate material allowed by sealant s ASTM C 920 Use Classification. 

3. Respective manufacturer's written installation instructions. 



B. Joint Sealant Backings: Install of kind indicated to support sealants during application and at 

position required to produce cross-sectional shapes and depths of installed sealants relative to 

joint widths that allow optimum sealant movement capability. 

1. Do not leave gaps between ends of sealant backings. 

2. Do not stretching, twisting, puncturing, or tearing backings. 

3. Remove absorbent sealant backings that have become wet or;damaged before sealant 

application and replace with dry materials. 

4. Install bond-breaker tape behind sealants where backings are not used between sealants 

and backs of joints. 

C. Joint Sealants: Install at same time as backings using proven techniques that comply with 

following: 

1. Place sealants so they directly contact and fully wet joint substrates. 

2. Completely fill recesses in each joint configuration. : 

3. Produce uniform, cross sectional shapes and depths relative to joint widths that allow 

optimum sealant movement capability. 

4. Immediately after sealant application and before skinning or curing begins, tool sealants 

according to requirements specified in subparagraphs 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. 

a. Remove excess sealant from surfaces adjacent to joints. 

b. Use tooling agents that are approved in writing by sealant manufacturer and that do 

not discolor sealants or adjacent surfaces. 

c. Use masking tape to protect surfaces adjacent to recessed tooled joints. 

D. Expanding Foam Sealants: Install each length of sealant immediately after removing protective 

wrapping. Do not pull or stretch material. Produce seal continuity at ends, turns, and 

intersections of joints. For applications at low ambient temperatures,; apply heat to sealant in 

compliance with sealant manufacturer's written instructions. 

3.4 CLEANING 

A. In-Progress Cleaning: Remove excess sealant or sealant smears adjacent to joints as Work 

progresses by methods and with cleaning materials approved in writing by manufacturers of 

joint sealants and of products in which joints occur. 

Centra! Fire Station, Temple, TX August 17, 2009 



A. General Requirements: Protect 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 so installations with repaired areas are indistinguishable from original 

Work.
