Resilient and Rubber Flooring Installation
About 12% of the C-15 exam covers sheet layout, adhesives, rolling and seam sealing, and resilient trim. CSLB lists the Armstrong installation manual and Congoleum's brochures as references. This page is a short survey; the PrepPass C-15 study guide teaches each step in full.
Fitting and seams
Sheets are fit by freehand knifing, straight scribing or pattern scribing. Thin and felt-back goods are double-cut; heavy goods are recess-scribed with adhesive spread.
Order
Install patterned pieces in the order cut, from the outside of the roll first.

The trowel notch controls the amount of adhesive. Fully adhered sheet is rolled with a 100-lb roller immediately and again at the end.
Tile borders
Border tiles at opposite walls equal and at least half a tile.
