Pre-Installation Check: No 24-Hour Acclimation
Subfloor
Flat, dry, clean, and dust-free, with no raised spots, standing water, or debris that affects installation.
Site
Avoid moisture, standing water, and open flame. Start pre-laying once site conditions are stable.
Material
Check roll direction, color, batch consistency, and edge condition before trimming.
Tools
Prepare knives, straightedge, tape measure, rollers, welding tools, welding rod, trimming knife, and cleaning tools.
Do not copy the base-mat rule of 24-hour acclimation before installation. Proceed after inspection.
Keep From the Standard Process
Use a flat, dry, dust-free subfloor; pre-lay and align before installation; keep seams straight and edges aligned; compact and inspect after completion.
Mandatory Changes
Peel the release liner after bonding; do not use glue; weld seams on both sides; do not wait for 24-hour acclimation before installation.
Installation Steps
Unroll Naturally
Lay the roll flat. Avoid reverse rolling, twisting, or forced pulling. Do not stretch while fixing.
Align Baselines
Adjust along the center line or edge line. Confirm direction, straightness, and edge quality.
Confirm Seams
Reserve welding space. Clean and compact the seam area before welding.
Peel Release Liner
Remove the release liner promptly after bonding. Peel steadily and evenly.
Weld Both Sides
Weld continuously along the front seam, check the back side, then complete the back weld.
Compact and Edge
Compact from the center outward, repeat at seams and corners, and trim vertically along the edge line.
Final Inspection Checklist
Liner
Release liner removed; no liner remains under the roll.
Glue
No glue used, including full-spread, touch-up, or spot gluing.
Welding
Seams welded on both sides; welds are continuous, full, and not missed.
Acclimation
No unnecessary 24-hour acclimation wait before installation.
Appearance
Flat surface with no arching, curling, contamination, or obvious knife marks.
Compaction is not a glue remedy. Rework if hollow areas or seam problems are found.
