Which adhesive type is generally recommended for installing rubber flooring in commercial applications?
Answer: Solvent-based contact cement
Solvent-based contact cement provides the high initial tack and strong permanent bond needed for rubber flooring in demanding commercial environments.
The term 'flash cove' in resilient flooring installation refers to:
Answer: Turning the floor material up the wall to form an integral coved base
Flash coving turns the resilient sheet or tile up the wall to create a seamless, sanitary cove base that is integral to the floor, commonly used in healthcare and food service settings.
What is the purpose of heat welding seams in commercial sheet vinyl or linoleum installations?
Answer: To fuse seam edges together creating a watertight, monolithic surface
Heat welding melts a compatible welding rod into the seam groove, fusing the edges into one continuous surface that prevents moisture infiltration and seam lifting.
Which moisture test measures the relative humidity within a concrete slab using in-situ probes?
Answer: Relative humidity (ASTM F2170)
The ASTM F2170 in-situ relative humidity test uses probes inserted at 40% of slab depth to measure moisture within the concrete, providing a more accurate reading than surface-only tests.
What is the correct direction to install strip or plank hardwood flooring relative to floor joists?
Answer: Perpendicular to the joists
Hardwood planks should run perpendicular to floor joists so each board crosses multiple joists, maximizing structural support and minimizing deflection.
When installing luxury vinyl tile (LVT) using the dry-back glue-down method, the floor temperature during installation should be maintained at:
Answer: Between 65°F and 85°F
Most LVT adhesive manufacturers specify a working temperature range of 65°F–85°F for proper adhesive open time, tack, and bond development.
What does a floor flatness specification of 3/16 inch per 10 feet mean for a flooring installer?
Answer: No high or low spots greater than 3/16 inch should exist within any 10-foot span
This tolerance means that a 10-foot straightedge laid anywhere on the subfloor should not reveal a gap greater than 3/16 inch, ensuring adequate flatness for the flooring product.
