question 33
wood siding
should be at least four inches above roofing
should be two inches above grade
will wick moisture through end grains
does not hold paint well
should not cover any part of the foundation wall

Explanation:

1. For the first question about hard - board problems: Rot, swelling, delamination, and bucking are common issues with hardboard. Efflorescence is not a typical problem for hardboard. Efflorescence is more related to the appearance of salts on the surface of masonry or concrete materials due to moisture movement.
2. For the second question about wood siding: Wood is hygroscopic and will wick moisture through its end - grains. Wood siding should be at least six inches above grade to prevent moisture absorption and decay, not two inches. It should be several inches above roofing to prevent water intrusion. It can hold paint well if properly prepared. And it should not cover the foundation wall to avoid moisture and pest issues.

Answer:

1. E. efflorescence
2. C. will wick moisture through end grains
