Finish TradesQuestion 429 of 700
In finish carpentry, what is the PRIMARY reason to leave a small expansion gap around the perimeter of a floating laminate or engineered wood floor?
a.To make the floor easier to sweep
b.To provide space for electrical wiring
c.To let dust escape from under the floor
d.To allow the flooring to expand and contract with humidity changes without buckling
Explanation
A floating floor expands and contracts with humidity, so a perimeter expansion gap (hidden by baseboard or trim) prevents the field from buckling or peaking. The gap is not for sweeping, wiring, or dust venting, and omitting it commonly causes the floor to lift or bow.
