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. Porous joint substrates
include the following:

a. Metal.
b. Glass.
c. Metal panels.
d. Cement board siding
B. Joint Priming: Prime joint substrates where recommended by joint-sealant manufacturer or as indicated

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 stretch, twist, puncture, or tear sealant backings.
3. Remove absorbent sealant backings that have become wet before sealant application and
replace them with dry materials.
D. Install bond-breaker tape behind sealants where sealant backings are not used between sealants and
backs of joints.
E. Install sealants using proven techniques that comply with the following and at the same time backings
are installed:

cut along one side, verifying adhesion to opposite side. Repeat procedure for opposite
side.
2. Inspect tested joints and report on the following:
a. Whether sealants filled joint cavities and are free of voids.
b. Whether sealant dimensions and configurations comply with specified requirements.
c. Whether sealants in joints connected to pulled-out portion failed to adhere to joint
substrates or tore cohesively. Include data on pull distance used to test each kind of
product and joint substrate. Compare these results to determine if adhesion passes
sealant manufacturer's field-adhesion hand-pull test criteria.
3. Record test results in a field-adhesion-test log. Include dates when sealants were installed,
names of persons who installed sealants, test dates, test locations, whether joints were primed,
adhesion results and percent elongations, sealant fill, sealant configuration, and sealant

contacts original sealant.
B. Evaluation of Field-Adhesion Test Results: Sealants not evidencing adhesive failure from testing or
noncompliance with other indicated requirements will be considered satisfactory. Remove sealants that
fail to adhere to joint substrates during testing or to comply with other requirements. Retest failed
applications until test results prove sealants comply with indicated requirements.
3.5 CLEANING
