Flooring — FAQ
What wear layer thickness do contractors need for commercial jobs?
Spec 12 MIL minimum for commercial. Residential rentals can use 6-8 MIL. Thicker wear layers reduce callbacks and warranty claims—critical for maintaining profit margins.
Can I install LVP directly over existing tile or concrete?
Yes, if the subfloor is level within 3/16" over 10 feet. Grout lines need skim coating. Concrete requires moisture testing—some LVP handles up to 90% RH without underlayment.
What's the difference between SPC and WPC cores?
SPC is stone-plastic composite—rigid, dense, handles heavy loads. WPC is wood-plastic composite—softer, warmer, more comfortable. SPC installs faster on imperfect slabs with less prep.
Do I need underlayment with these vinyl planks?
Most rigid core LVP has attached underlayment. For concrete slabs above 80% RH, use a vapor barrier. Sound-reduction underlayment helps in multi-family builds but adds cost.
How many square feet can a crew install per day?
Experienced two-person crews lay 1,000-1,500 sq.ft daily with click-lock. Factor in 30% more time for intricate cuts, bathrooms, and pattern matching. Tool quality directly impacts speed.
Are tapping blocks universal across brands?
No—thickness matters. Triple-edge blocks (3mm-8mm) cover most inventory. Double-sided blocks work with click-lock and T&G. Always verify edge profile matches your flooring before starting.
