Cut the seam net, not full. Do not add fullness to the cut by placing scrap under the seam. Keep the knife blade parallel to the
straightedge, at a 90° angle to the floor covering. All seams are to be double cut “dry”.
When using the FULLY ADHERED method, the sheets will be adhered up to a pre-determined dry zone, then the seam is cut
and a uniform application of MT- 711 is applied. After providing sufficient open time, carefully position the sheets into the
adhesive and roll across the seam with a hand roller.

must be rolled flat and well bonded to the adhesive for a good seam. If the bond using the Releasable Bond
method is not sufficient, it may be necessary to re-glue the seam area with a 6” band of MT-711. If the Loose-Laid method is
used, after cutting the seam, apply a 6” band of MT-711 at the seam line, provide sufficient open time (tacky/wet), and then
carefully position the sheet into the adhesive. Use caution to prevent the sheet edges from getting into the adhesive. Roll the
seam area with a hand roller.
SEAM SEALING
All seams in
Insight
®
Plus GB
flooring must be sealed with Mannington MLG-33 two-part seam sealer. Thoroughly mix all of
Part A and Part B into the supplied VST applicator bottle. When using MLG-33 two-part seam sealer, it is necessary to mix the
entire contents of Parts A and B. Once mixed, MLG-33 cannot be saved for re-use. Check the flow of sealer through the
applicator tip on a scrap piece of material before use. If the flow is restricted, insert the cleaning wire into the tip to clear the
obstruction. Before sealing the seam, make sure the seam cut is clean, dry, and free of adhesive contamination.
Insert the plastic fin of the VST slightly back from one end of the wall and push forward to make full penetration of the fin. Use
your forefinger to apply a downward pressure on the flat, textured “head” of the VST. Gently squeeze the bottle to start the
flow of the sealer. In a slow, continuous motion, pull the applicator along the length of the seam.
You must apply seam sealer into the seam cut and leave a bead of sealer approximately 1⁄8" wide centered on the seam.
Remember, it is crucial that the seam sealer be applied to the full thickness of the floor covering from top to bottom.
To ensure a strong, tight seam, make certain there are no skips or voids along the cut. Allow seam sealer to completely dry
before walking on the seam or moving furniture over it. We recommend waiting 24 hours.

711 or V-88 with a brush or paint roller. Seal all coved corners using Mannington’s MLG 33 seam sealer.
FINISHING & MAINTENANCE
Molding & Base Installation
• Protect all exposed edges of the flooring with trim or restrictive molding.
• Always use moldings and transition strips over product edges.
• Nail wood moldings into the wall and not into the floor covering.
• Use metal or vinyl transition or reducer strips where LVS meets other types of flooring and at doorways.
• Apply a bead of silicone or latex caulk around bathtubs, shower stalls, toilets, and patio doors.
JOBSITE CLEANUP
To enhance the appearance of the finished installation, it is always good practice to thoroughly clean the area before leaving.
• Sweep the floor.
• Remove all scraps and trash from the jobsite. (Leave any large pieces of flooring, rolled face-out, with the customer
for
future
repairs.)
• Remove any adhesive smears or residue from the surface of the flooring with a clean cloth dampened with mineral
spirits or lighter fluid.
• If possible, wait 24 hours before moving furniture or appliances onto or across the floor. Always use wood or
hardboard runways to move furniture and/or appliances, even when using a dolly. This is especially important
when using the loose laid installation method.
• Leave Mannington Maintenance and Warranty literature with the customer. These are available from your
Mannington
Distributor.
