PART 3 EXECUTION

EXAMINATION

Verify site conditions under provisions of Section [01039.] [________.]

Verify that substrate surfaces are [prime painted and] ready to receive work, and conform to requirements of the wall covering manufacturer.

Measure moisture content of surfaces using an electronic moisture meter. Do not apply coverings unless moisture content of surfaces are below the following maximums:

Plaster and Gypsum Wallboard: [12] [____] percent.

Masonry, Concrete, and Concrete Unit Masonry: [12] [____] percent.

Wood Surfaces: [15] [____] percent, measured in accordance with ASTM D2016.

PREPARATION

Fill cracks and smooth irregularities with filler; sand smooth.

[Wash impervious surfaces with trisodium phosphate, rinse and neutralize; wipe dry.]

Sand glossy surfaces; seal marks which may bleed with shellac.

Remove electrical, telephone, and [________] wall plates and covers.

[Apply [one coat] [two coats] of primer sealer to

substrate surfaces. Allow to dry. Lightly sand smooth.]

Vacuum clean surfaces free of loose particles.

INSTALLATION

Apply adhesive and wall covering in accordance with manufacturer's instructions.

Apply adhesive to [wall] [fabric] surface immediately prior to application of wall covering. [Let contact adhesive set tack free.]

Use wall covering [in roll number sequence.] [in pattern sequence.] [________.]

Razor trim edges on flat work table.	Do not razor cut on gypsum board surfaces.

Apply wall covering smooth, without wrinkles, gaps or overlaps. Eliminate air pockets and ensure full bond to substrate surface. Butt edges tight.

[Horizontal] [Vertical] seams are [not] acceptable.

Do not seam within [2] [____] inches ([50] [____] mm) of internal corners or within [6] [____] inches ([150] [____] mm) of external corners.

Cover spaces above and below windows, above doors, in [pattern] [________] sequence from roll.

[Apply fabric covering to electrical, telephone and [________] wall plates prior to replacing.]

[Where wall covering tucks into reveals, or metal wallboard or plaster stops, apply covering with contact adhesive within [6] [____] inches ([150] [____] mm) of wall covering termination. Ensure full contact bond.]

[Install termination trim.]

Remove excess wet adhesive from seam before proceeding to next wall covering sheet. Wipe clean with dry cloth.
