PART 3 - EXECUTION

3.1 JOB CONDITIONS

A. Temperatures:

1. Do not perform work until surfaces and materials have been maintained at minimum of 16 degrees C (60 degrees F) for three (3) days before work begins.

2. Maintain minimum temperatures of 16 degrees C (60 degrees F) until adhesives are dried or cured.

B. Lighting:

1. Do not proceed unless a minimum lighting level of 15 candela per

0.09 square meter (15 candela per square foot) is provided.

2. Measure light level at mid-height of wall.

C. Ventilation: Provide continuous ventilation as required to rid the spaces in which the wall coverings are being installed of volatile compounds given off by the wall coverings, sealers and adhesives and as recommended by the product manufacturer for full drying or curing.

D. Protect other surfaces from damage resulting from installation of wall coverings. Provide drop cloths, shields and protective equipment to prevent primers, adhesives or wall covering from fouling adjacent surfaces and in particular, storage and preparation areas.

E. Store flammable rubbish, waste, cloths and materials which may constitute a fire hazard, in closed metal containers. Daily remove and properly dispose of flammable wastes from the site.

3.2 SURFACE CONDITION AND PREPARATION

A. Inspect surfaces to receive wall coverings to assure that:

1. Patches and repairs to substrates are completed.

2. Surfaces are clean, smooth and prime painted.

3. Masonry and concrete walls are to have flush joints. Coat these walls with cement plaster or wall/liner as substrate preparation.

B. Surfaces to receive wall covering are to be dry. Test moisture content of plaster, concrete, and masonry walls with an electric moisture meter. The moisture content is not permitted to be more than 5 percent.

Submit test results.

C. Do not proceed until discovered defects have been corrected by other trades and surfaces are ready to receive wall covering.

09 72 16 - 4

D. Carefully remove electrical outlet and switch plates, mechanical diffusers, escutcheons, registers, surface hardware, fittings and fastenings, prior to starting work and store items for reinstallation.

3.3 APPLICATION OF ADHESIVE

A. Mix and apply adhesives in accordance with manufacturer's directions.

B. Prevent adhesive from getting on face of wall covering.

C. Apply adhesive to wall covering back.

3.4 INSTALLATION

A. Use wall covering of same batch or run in each area. Use fabric rolls in consecutive numerical sequence of manufacture.

B. Install material completely adhered, smooth, clean, without wrinkles, air pockets, gaps or overlaps.

C. Extend wall covering continuous behind non-built-in casework and other items which are not bolted to the walls.

D. Install wall covering before installation of resilient base. Extend wall covering not more than 6 mm (1/4 inch) below top of resilient base.

E. Install wall covering panels consecutively in order in which they are cut from the roll including filling spaces above or below windows, doors, or similar penetrations.

F. Do not install horizontal seams.

G. Except on match patterns, hang fabric by reversing alternate strips, except as recommended by the manufacturer.

H. Cutting:

1. Cut on a work table with a straight edge.

2. Joints or seams that are not cut clean are unacceptable.

3. Trim additional selvage to achieve a color and pattern match at seams. Overlapped seams are not allowed.

4. Do not double cut seams on wall unless specified.

5. If double cutting on the wall is necessary, place a three inch strip of Type I wall covering under pasted edge.

a. Do not cut into wall surface.

b. After cutting, remove strip and excess adhesive from seam before proceeding to next seam.

c. Smooth down seam in adhesive for tight bond and joint.

I. Trim strip-matched patterns which are not factory pre-trimmed.

J. Inside Corners:

09 72 16 - 5

1. Wrap wall covering around corners.

2. Do not seam within 50 mm (2 inches) of inside corners.

3. Double cut seams.

K. Outside Corners:

1. Wrap wall covering around corners.

2. Do not seam within 152 mm (6 inches) of outside corners.

3. Double cut seams.

3.5 CLEANING AND INSTALLING TEMPORARY REMOVED ITEMS
