Question 1

When installing quarter-round shoe molding along a baseboard after a floating floor installation, what is the correct fastening method?

Accepted Answer

Nail into the baseboard only

Answer

Quarter-round must be nailed to the baseboard (not the floor) so the floating floor can expand and contract freely beneath it.

Question 2

A floor reducer shows a visible gap on the low-height side after installation. What is the most likely cause?

Accepted Answer

Insufficient expansion gap was left in the flooring, preventing the reducer from lying flat

Answer

If the flooring planks are installed too tight to the reducer track, the reducer cannot sit flat, creating a visible gap on one side.

Question 3

Which trim piece is used to finish the exposed flooring edge at a fireplace hearth?

Accepted Answer

End cap

Answer

An end cap (also called a baby threshold) is used to finish a flooring edge that terminates at a vertical surface like a fireplace hearth or a step.

Question 4

On a hardwood floor installation, scotia molding is preferred over quarter-round by many installers because:

Accepted Answer

Its flatter profile hugs the floor surface better and produces a cleaner look

Answer

Scotia molding has a concave profile that lies flatter against the floor than a quarter-round, resulting in a tighter, more finished appearance at the wall.

Question 5

When mitering outside corner joints on baseboard trim, what combined angle of the two miter cuts should equal?

Accepted Answer

90 degrees total

Answer

Each piece is cut at 45 degrees, and the two cuts together form a 90-degree outside corner joint.
