PART 3 EXECUTION

3.01 INSTALLATION, GENERAL

A. Provide sealing and caulking to produce weathertight conditions throughout.

Caulk around exterior and interior masonry openings; seal construction joints as shown. Joints shall be caulked before painting adjacent work.

Examine joint surfaces, backing and anchorage of units forming sealant rabbet, and conditions under which sealant work is to be performed; notify of conditions detrimental to proper and timely completion of work and performance of sealants. Do not proceed until unsatisfactory conditions are corrected.

3.02 WEATHER CONDITIONS

A. Do not proceed with installation of sealants when adverse weather conditions are forecasted, nor when temperatures are outside manufacturer's recommended limitations. Proceed only when conditions are favorable for proper cure and development of bond strength. Wherever joint width is affected by ambient temperature variations, install elastomeric sealants only when temperatures are in the lower third of manufacturer's recommended installation temperature range, so that sealant will not be subjected to excessive elongation and bond stress at subsequent low temperatures.

3.03 JOINT SURFACE PREPARATION

A. Clean joint surfaces immediately before installation of sealant or caulking compound. Remove dirt, unsecure coatings, moisture and other substances which would interfere with bond of sealant or caulking compound.

B. Masonry and wood shall be sound and dry. Cure concrete a minimum of 28 days. Etch concrete and masonry joint surfaces to remove excess alkalinity, unless sealant manufacturer's printed instructions indicate that alkalinity does not interfere with sealant bond and performance. Etch with 5% solution of muriatic acid; neutralize with dilute ammonia solution, rinse thoroughly with water and allow to dry before sealant installation.

C. Roughen joint surfaces on vitreous coated and similar non-porous materials, wherever sealant manufacturer's data indicates lower bond strength than for porous surfaces. Rub with fine abrasive cloth or wool to produce a dull sheen.

3.04 INSTALLATION

A. Comply with sealant manufacturer's instructions except where more stringent requirements are shown or specified. Prime or seal joint surfaces as recommended by sealant manufacturer. Do not allow primer/sealer to spill or migrate onto adjoining surfaces.

B. Install sealant backer rod for liquid elastomeric sealants, except where shown to be omitted or as recommended by sealant manufacturer.

C. Employ only proven installation techniques, which will ensure that sealants will be deposited in uniform, continuous ribbons without gaps or air pockets, with complete "wetting" of the joint bond surfaces equally on opposite sides. Except as otherwise indicated, fill sealant rabbet to a slightly concave surface, slightly below adjoining surfaces. Horizontal joints between a horizontal surface and a vertical surface shall be filled to form a slight cove, so that joint will not trap moisture and dirt.

D. Install sealants to depths as shown, or if not shown, as recommended by sealant manufacturer but within the following general limitations, measured at the center (thin) section of bead.

1. For normal moving joints sealed with elastomeric sealants, but not subject to traffic, fill joints to a depth equal to 50% of joint width, but neither more than ½ in. deep nor less than ¼ in. deep.

E. Do not allow sealants or compounds to overflow or spill onto adjoining surfaces, or to migrate into the voids of adjoining surfaces including rough textures such as exposed aggregate panels. Use masking tape or other devices to prevent staining of adjoining surfaces, by either the primer/sealer or the sealant/caulking compound.

F. Remove excess and spillage of compounds promptly as the work progresses.

Clean the adjoining surfaces by whatever means may be necessary to eliminate evidence of spillage, without damage to the adjoining surfaces or finishes.

3.05 CURING

A. Cure sealants and caulking compounds in compliance with manufacturer's instructions and recommendations to obtain high early bond strength, internal cohesive strength and surface durability.

B. Protect sealants and caulking compounds during construction period to prevent deterioration or damage (other than normal wear and weathering).
