Q
  1. Concrete Substrates
A

All concrete substrates should be tested for IRH (Internal Relative Humidity) according to ASTM F 2170. Calcium
Chloride tests may be conducted in addition to IRH and must be performed per the latest edition of ASTM F 1869.

Q

Seaming

A

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.

106
Q

Seaming

A
  1. Recess scribe method – On non-patterned material, trim approximately 1/2” 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”–1” 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 should be installed that day.
107
Q

Seaming (A to M)

A
  1. Double cut method – Overlap the salvage edges to align the pattern width and length. On Naturelife™ wood look
    align the bevel edge of the planks. Place a 4” 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.

Q

NOTE:

A

NOTE: TO ENSURE PROPER BONDING OF THE MATERIAL, IT IS RECOMMENDED TO ROLL IN THE MATERIAL NEXT TO THE WALLS WITH A HAND SEAM ROLLER.

Q

Seaming I

A

i. 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.

119
Q

Note:

A

NOTE: 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.

HEAT WELDING ( A to L )

A

a. Heat welding is the recommended procedure for Biolife™ and Naturelife™ seams, coving and corner fill pieces.
Professionally heat welded seams provide a strong, watertight, hygienic, monolithic surface.

126
Q

HEAT WELDING

A

b. The welding rod (4 mm) is designed to melt at the same temperature as the sheet flooring, permanently thermally
fusing the two together.

127
Q

HEAT WELDING

A

c. Heat welding should be done after the flooring adhesive has set up, usually the following day.

128
Q

HEAT WELDING

A

d. Seam edges should be slightly gapped and vertical. Wide gapped or undercut seams will prevent quality welds.

129
Q

HEAT WELDING

A

e. The depth of the groove should be 1/2 to 2/3 the thickness of the material. Be careful not to go too deep. The
groove must also be centered along the two edges. This is very important to ensure proper strength and bonding
of the welding rod.

130
Q

HEAT WELDING

A

f. Clean grooves thoroughly of all foreign contamination, including dust.

131
Q

HEAT WELDING

A

g. Use only professional quality welding equipment that will maintain sufficient temperatures. Many types, sizes and
styles of welding tips are available today. A tip must be chosen to produce a quality weld without damaging the
appearance of the sheet vinyl.

132
Q

HEAT WELDING

A

h. Preheat welding gun before beginning. Temperature should be set approximately 750°F.
Practice on a scrap piece to fine tune temperature and pace for type of substrate and site conditions. Long
extension cords may affect welding temperature settings.

133
Q

HEAT WELDING

A

i. Determine the correct welding speed by ensuring that the welding rod actually fuses into the groove. A small ridge must
form on either side of the welding rod, at the vinyl surface. If no ridge forms, you have not heat welded the seam.

134
Q

HEAT WELDING

A

j. While the welding rod is still warm, trim off 1/2–2/3 the excess rod with a spatula knife and trim plate in one
continuous movement.

135
Q

HEAT WELDING

A

k. After the rod has cooled to room temperature, make the final trim pass using only a razor sharp spatula knife in
one continuous movement.

136
Q

HEAT WELDING

A

l. Apply a glaze to the surface of the trimmed weld. Remove the tip from the welding gun. Hold the gun a few inches
above the welded seam and apply hot air along the seam until the surface of the weld rod begins to shine. The
glazed seam will be less porous, smoother, and less noticeable.

Chemical Weld ( A to D )

A

a. Ensure seam is completely clean and dry.

139
Q

Chemical Weld

A

b. Pour entire contents of sealer into applicator bottle and allow any air bubbles to dissipate.

140
Q

Chemical Weld

A

c. Insert the tip of the applicator down into the seam. Pull back at a steady pace applying a constant pressure on the
bottle, applying enough sealer to seal the edges of the sheet and leaving a small bead (1/8”) of sealer on the surface
of the seam.

141
Q

Chemical Weld

A

d. Keep all traffic off the seam for a minimum of 24 hours.
