PART 3 - EXECUTION 3.1 GENERAL

A. Building Envelope: Caulk, gasket or otherwise seal all joints, transitions in materials and penetrations in the building envelope to ensure a continuous air barrier.

B. Seal all wall, floor and joint penetrations to prevent pest entry. Use pest screens for

openings greater than ¼”. C. Seal all material joints on interior. D. Seal at acoustical walls.

3.2 PREPARATION A. Surface Preparation:

1. Thoroughly clean and dry surfaces prior to installation. 2. Clean metals with manufacturer’s recommended solvent, wipe clean.



3. Remove any dust, dirt, oil, grease, and any other foreign substances from surface areas to receive sealant.

4. Prime surfaces as recommended by sealant manufacturer. Prime all concrete, brick masonry, and concrete unit masonry substrates, regardless of manufacturer’s requirements.

5. Mask off any adjacent surfaces which are not to receive sealant. 3.3 APPLICATION

A. General: Comply with sealant manufacturer’s installation instructions. Provide bond breaker tape as required to prevent sealant adhesion to backing. Joint depth 1/2 joint width, but not less than 1/4 inch nor more than 1/2 inch, unless otherwise specified by sealant manufacturer.

B. Joint Backing: Install as recommended by sealant manufacturer to prevent sealant

from adhering to rigid, inflexible materials or joint surfaces where such adhesion would result in sealant failure. Sealant shall bond two opposing joint surfaces.

C. Sealant Application:

1. Do not install sealants during rainfall or very windy conditions when windborne contaminants can become embedded in uncured sealant.

2. Apply materials with hand gun, powered gun, or trowel to completely fill voids and joints, free of wrinkles and skips.

3. Observe temperature control in accordance with sealant manufacturer's written recommendations.

4. Do not allow any air entrapment in sealant. 5. Extrude sealant fully into joint to be sealed, tool sealant to press into joint,

assuring full adhesion to sides of joint surfaces, resulting in a uniformly smooth concave profile.

6. Tool sealant using only materials recommended by sealant manufacturer. 7. Remove masking tape immediately after sealant application to produce clean,

sharp line. 8. Do not seal weeps or drainage provisions in sill channels. 9. Allow sealants to cure adequately prior to covering with other Work. 10. Coordinate sealant installation with concrete, masonry, and flashing

applications. 11. Apply sand to wet sealant surfaces to match finish of adjacent concrete and

masonry conditions. 3.4 CLEANING

A. Remove all empty containers, materials, and debris from the site. Dispose off site in accordance with applicable regulations.

B. Remove any sealant spills, masking materials, and similar items from all surfaces not

intended for their application.

C. Clean and repair surfaces soiled or damaged by sealant Work.
