c. Ventilation
d. Sealants

4. Installing the PVC membrane after the wall assembly has been completed:
a. Is critical to ensuring a watertight floor
b. Will almost always lead to failure

d. Should be done only if the deck has posts

5. Drying can be aided by:
a. Slope of the deck surface
b. Scuppers
c. Venting of trapped air spaces
d. A closed soffit

6. Neat and waterproof details can be assured by:
a. A hot-welded PVC membrane
b. Periodic maintenance
c. Pre-manufactured flashing
d. Overlapping two layers of building paper

7. When installing a PVC membrane over an existing system that has failed, it is necessary to:
