3" at edges, and 6" intermediate grid for 1/4 Performance Category underlayment panels and 6" at edges, and 8" intermediate grid for 11/32 Performance Category underlayment panels
3" at edges, and 6" intermediate grid for 1/4 Performance Category underlayment panels and 6" at edges, and 12" intermediate grid for 11/32 Performance Category underlayment panels

5. Sources of moisture that can affect your finish flooring are?

Direct Wetting and Ambient
Crawl space concrete spaces
Propane heaters
All of the above

6. Prior to installing the finish flooring:

It is recommended the Heating and Air Condition system should be operational
Acclimation of finished hardwood flooring is not required
The installed subfloor, underlayment, and flooring should be acclimated
Both A and C
Both A and B

7. The best methods to dry the subfloor are?

Use of fuel fired heaters
Use of dehumidifiers and fans
Use of electric heaters
Both B and C

8. Tile installations ________.

Always require a 16" joist spacing
Depends on the service classification, joist spacing, and tile size
Never requires an underlayment layer
Can never be installed when joists are space 24" on-center

9. Potential sources of Ambient moisture are:

Propane heaters
Rain or Snow through a window or door opening
Damp or Wet crawlspace
A poured concrete basement floor installed after the wood floor is installed
A, C and D

10. To minimize nail pops you should:

Select the proper fastener length
Use deformed-shank nails
Prepare the framing surface
Use foot pressure near the fastener to assure contact between the underlayment and the subfloor
All of the above
