degrees C) for at least 24 hours prior to installation and relative
humidity at approximately that at which the area is to be maintained.

## 3.03 [INSTALLATION]{.underline}

A. [General]{.underline}: Perform installation in accordance with
manufacturer's instructions, except where more strigent requirements are
shown or specified, and except where project conditions require extra
precautions or provisions to ensure satisfactory performance of the

at inside corners.

3\. [Provide cut-outs]{.underline} where required.

4\. [Follow manufacturer's instructions]{.underline} for cutting wall
covering, using tools designed to cut type of wall covering materials
being installed. Inspect material prior to cutting for defects. Use new,
clean, sharp blades and change blades after each cut.

covering in area where it is to be installed. Where cutting is
necessary, provide properly prepared, straight, and unfrayed edges.

6\. [Apply a full spread of adhesive]{.underline} in an even layer to
substrate and allow to become tacky before applying wall covering.
Follow MSDS instructions for ventilation requirements.

7\. [Install prefitted wall covering]{.underline} from top to bottom
between two plumb lines and trim as necessary. Overlap and double-cut
wallcovering, with sufficient overlap to ensure cut is made through
acrylic backing and not the selvedge. Do not damage substrate when
double cutting. Press panel gently from top to bottom to remove bubbles
or wrinkles. Butt edges snugly at seams and against vertical
obstructions.

soft bristled brush. Should any trace of stain remain, a mild household
cleaner should be used.

## 3.05 [PROTECTION]{.underline}

A. [Protect installation]{.underline} with a nonstaining building paper.
Do not use a moisture barrier such as plastic film.
