			2.	Install all cuts and rolls in consecutive sequence.
			3.	Do not reverse sheets for seaming.

			6.	Push the fitted sheet lightly against the wall.
			7.	Continue freehand knifing around the room.
		J.	Seaming
	** NOTE TO SPECIFIER ** Seams may be cut by either overlap and double cut or by straight edging or edge trimming one side, and recess scribing the second sheet. Delete method not required.
			1.	Recess scribe method - On non-patterned material, trim approximately 1/2 inch (13 mm) off one salvage edge of seam with a straightedge and sharp knife or edge trimmer. Cut second sheet with proper extra length. Position second sheet with a 1/2 inch to 1 inch (13 mm to 25 mm) overlap over first sheet at the seam. Set recess scribes so that the seam will have a slight gap, about half the thickness of a razor blade. If cut too full, it will result in bubbles or ridges. Recess scribe seam. Repeat for as many sheets as necessary to complete the area. Sheets shall be installed that day.
			2.	Double cut method - Overlap the salvage edges to align the pattern width and length. On Naturelife wood look, overlap the salvage edge approximately 1/2 inch (13 mm) to align the bevel edge of the planks. Place a 4 inches (102 mm) wide scrap of material under the seam area. Place a straight edge directly over the beveled edge of the plank, and using a new razor blade, hold the knife straight up and down and cut through both pieces in one cut.
			3.	Lap back all overlapped sheets as one, half way back.
			4.	Do Not back roll vinyl backed floorings.
			5.	Do Not butt factory edges.
			6.	Do Not straight edge and butt, or edge trim and butt.
			7.	Snap white chalk lines along areas where adhesive will be spread to ensure an even and straight line of adhesive.
			8.	Spread adhesive with proper notched trowel over entire area. Be very careful not to leave any adhesive ridges or puddles.
	** NOTE TO SPECIFIER ** The sub-floor porosity and room conditions (temperature, humidity, etc.) can affect the working time of the adhesive.
			9.	Push lapped flooring from the fold into adhesive, working toward the wall. DO NOT FLOP MATERIAL IN - air will be trapped, causing bubbles.
			10.	Roll floor with a minimum 100 lb (45 kg) roller in both directions. Roll across width first, then along length.
	** NOTE TO SPECIFIER ** To ensure proper bonding of the material, it is recommended to roll in the material next to the walls with a hand seam roller.
			11.	After material has been laid into the adhesive, recess scribe the seams using either the scribe blade or scribe pin. Hold the knife blade straight up and down to make final cut. DO NOT UNDERCUT.
	** NOTE TO SPECIFIER ** Set recess scribes so that the seam will have a slight gap, about half the thickness of a razor blade. If cut too full, it will result in bubbles or ridges.
			12.	Roll the seam with a hand roller.
			13.	Repeat the same procedure for additional seams in the room.
	** NOTE TO SPECIFIER ** Delete if not required.

			6.	Clean up any excess sealer using a dry towel within 30 seconds after seam sealing.
			7.	Caution: Chemical welding solution left on the surface of the floor for more than 30 seconds may damage the surface of the material.
			8.	Keep all traffic off the seam for a minimum of 24 hours.
	** NOTE TO SPECIFIER ** Delete if not required.
		L.	Flash Cove Installations
			1.	Flash coving is an extension of the sheet flooring up the wall to form a wall base.
			2.	Seams in the flash coved areas shall be treated the same as seams throughout the rest of the installation.
			3.	After fitting material into adhesive, use a hand roller to assure contact with the adhesive.
	3.5	PAINTING
		A.	Remove hardware and hardware accessories, plates, machined surfaces, lighting fixtures, and similar items already installed that are not to be painted. If removal is impractical or impossible because of size or weight of the item, provide surface-applied protection before surface preparation and painting.
		B.	Before applying paint or other surface treatments, clean substrates of substances that could impair bond of the various coatings. Remove oil and grease before cleaning.
			1.	Schedule cleaning and painting so dust and other contaminants from the cleaning process will not fall on wet, newly painted surfaces.
		C.	Clean and prepare surfaces to be painted according to manufacturer's written instructions for each particular substrate condition and as specified.
			1.	Provide barrier coats over incompatible primers or remove primers and re-prime substrate.
