CFI Flooring Materials & Installation Techniques 5

Question 1

Which adhesive type is generally recommended for installing rubber flooring in commercial applications?

Accepted Answer

Solvent-based contact cement

Answer

Solvent-based contact cement provides the high initial tack and strong permanent bond needed for rubber flooring in demanding commercial environments.

Question 2

The term 'flash cove' in resilient flooring installation refers to:

Accepted Answer

Turning the floor material up the wall to form an integral coved base

Answer

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.

Question 3

What is the purpose of heat welding seams in commercial sheet vinyl or linoleum installations?

Accepted Answer

To fuse seam edges together creating a watertight, monolithic surface

Answer

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.

Question 4

Which moisture test measures the relative humidity within a concrete slab using in-situ probes?

Accepted Answer

Relative humidity (ASTM F2170)

Answer

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.

Question 5

What is the correct direction to install strip or plank hardwood flooring relative to floor joists?

Accepted Answer

Perpendicular to the joists

Answer

Hardwood planks should run perpendicular to floor joists so each board crosses multiple joists, maximizing structural support and minimizing deflection.
