Provide backstop material that is compatible with sealant. Do not use oakum or other types of absorptive materials as backstops.

D. Cleaning solvents shall be type(s) recommended by the sealant manufacturer and in accordance with applicable environmental requirements. Protect adjacent glass, aluminum and bronze surfaces from solvents.

3.1 INSPECTION

A. Installer must examine substrates (joint surfaces) and conditions under which joint sealer work is to be performed, including joint width tolerances, and must notify Contractor in writing of unsatisfactory conditions. Do not proceed with joint sealer work until unsatisfactory conditions have been corrected in a manner acceptable to installer.

3.2 PREPARATION

A. Clean down joint surfaces using oil-free solvent for metal, glass, and other non-porous surfaces.

Surfaces to receive sealant shall be sound, clean and dry, and free of frost, laitance, curing compounds, waterproofing compounds, mastic compounds, corrosion, mill scale, rust, oil, tar, wax, paint, mastic, and similar contaminates.

B. Sandblast concrete in contact with form release agents.

C. Prime concrete, masonry, wood and similar porous surfaces. Brush out excess material to ensure a uniform film over the joint face. Allow primer to dry out before applying sealant.

D. Mask adjacent areas as necessary to obtain a neat sealant line.

3.3 INSTALLATION

A. Comply with the manufacturer's documented instructions except where more stringent requirements are shown or specified, and except where manufacturer's technical representative directs otherwise.

B. Mix two-part sealants by mixing the activator with the resin uniformly and thoroughly, in the proportions supplied to meet the recommendations of the sealant manufacturer. Sealant shall be mixed in a mechanical mixer, except very small amounts may be hand mixed with a trowel.

C. Clean out loose particles from joints immediately prior to application of primer. Apply primer to joints in concrete masonry units, wood, and other porous surfaces in accordance with sealant manufacturer’s documented instructions. Do not apply primer to exposed finished surfaces.

D. Install backer rod with a blunt rod or plain faced roller. Recess into joint to meet the sealant manufacturer's recommendations for joint width and depth ratio. Do not puncture, fold, twist, or crease backer rod.

E. Install bond breaker where sealant would otherwise bond to backer rod or joint filler.

F. Do not allow sealants or compounds to overflow from confines of joints, to spill onto adjoining work, or to migrate into voids of exposed finishes. Clean adjoining surfaces by whatever means may be necessary to eliminate evidence of spillage.

SCBL 227334 145-091 07 92 00-4

G. Install sealants in uniform, continuous ribbons without gaps or air pockets, with complete "wetting" of joint bond surfaces equally on opposite sides. Except as otherwise indicated, fill sealant rabbet to a slightly concave surface slightly below adjoining surfaces.

H. Where horizontal joints are between the horizontal surface and vertical surface, fill joint to form a slight cove, so that joint will not trap moisture and dirt.

I. Apply non-self-leveling sealants by holding the gun nozzle at an angle of about 45 degrees and move steadily along the joint so that a uniform bead is applied without dragging, tearing, or leaving unfilled spaces. Push the bead rather than draw it with the gun leading. Fill joints in vertical surfaces level with adjacent surfaces and tool within ten minutes of application with one continuous stroke to insure intimate contact with the joint surfaces, to remove any trapped air or voids, to consolidate material, and to provide a neat, uniform, appearance. Fill joints in horizontal surfaces holding the top surface of the sealant slightly below the adjacent surfaces.

J. Install self-leveling sealants to a depth equal to 75 percent of joint width but neither more than 5/8-inch deep or less than 3/8-inch deep as recommended by sealant manufacturer. Pour sealant into joints and fill to within 1/16-inch of adjacent surfaces, exercising care not to spill sealant on such surfaces. Refill any areas where sealant seeps out of joint through the expansion joint filler before sealant sets up.

3.4 CLEANING AND PROTECTION

A. Remove masking immediately after application and tooling operations are complete. Clean excess or spilled sealant from non-porous surfaces with solvent before curing. Clean excess or spilled sealant from porous surfaces with abrasive or mechanical means after curing.

B. Protect sealant where bituminous material is to be applied over thermosetting joint sealant with vinyl or polyethylene sheet material.

C. Cure sealants in compliance with manufacturer's instructions and recommendations to obtain high early bond strength, internal cohesive strength and surface durability. Advise Contractor of procedures required for cure and protection of joint sealers during construction period, so that they will be without deterioration or damage (other than normal wear and weathering) at time of Substantial Completion.

Replace or restore sealants which are damaged or deteriorated during construction period.

3.5 SCHEDULE OF SPECIAL SEALANT COLORS

A. Special sealant colors shall be as follows:

At perimeter of exterior wall openings Match adjacent colors At joints between wall & other surfaces Match wall color At miscellaneous locations shown on the Drawings Standard color to most closely match adjacent colors

After completing finishing operations in each space or area, reinstall items removed using workers skilled in the trades involved.

B. All surfaces to be scraped and wiped cleaned free of loose dirt and dust before finishing. After the first coat, putty holes, cracks, etc. with putty of a color to match that of finish. Bring putty flush to the adjoining surface.

C. Metal surfaces which are not galvanized or shop-coated shall be washed with mineral spirits to remove dirt and grease. Remove rust or scale by wire brushing or sandpapering clean.

D. Clean and treat galvanized metal chemically with a compound designed for this purpose, such as

"Lithoform", "Stibley", or "Solfo Metallic Coat", in accordance with the paint manufacturer's instructions.

Spot prime with primer specified for new surfaces where existing paint or primer has been partially removed by blistering, peeling, rupture, or cracking. Completely remove existing finish if 25 percent or more of the existing finish has failed or can be easily scraped off the surface.

3.3 APPLICATION

A. Paint coatings shall be applied by brush only in all historic structures.

B. Apply all materials under adequate illumination.

C. Extent of painting and finishing shall be to paint immediate area of any patch &/or repair. The immediate area shall mean edge to edge of a logical break where the detection of dissimilar appearance will not be readily identified. Areas without a discernable break shall be painted edge to edge.

E. Provide finish coats that are compatible with primers used.

F. Apply first coat to surfaces that have been cleaned, pretreated, or otherwise prepared for coating as soon as practicable after preparation and before subsequent surface deterioration.

G. The number of coats and film thickness required are the same regardless of application method. Do not apply succeeding coats until previous coat has cured as recommended by manufacturer.

H. Allow sufficient time between successive coats to permit proper drying. Do not recoat surfaces until previous coat has dried to where it feels firm, and does not deform or feel sticky under moderate thumb pressure, and until application of another finish coat does not cause undercoat to lift or lose adhesion.

I. Apply finish coatings by brush according to manufacturer’s instructions, and as follows:

1. Brushes: Use brushes best suited for type of material applied. Use brush of appropriate size for surface or item being coated.

J. Apply coating materials no thinner than manufacturer’s recommended spreading rate to achieve dry film thickness indicated. Provide total dry film thickness of the entire system as recommended by manufacturer.

K. Before applying finish coats, apply a prime coat, as recommended by manufacturer, to material that is required to be coated or finished and that has not been prime coated by others. Recoat primed and sealed surfaces where evidence of suction spots or unsealed areas in first coat appears to ensure a finish coat with no burn-through or other defects due to insufficient sealing.

SCBL 227334 145-091 09 90 00 - 5
