1. Which substrate is not suitable for wet areas?
Cement Back Board
Dry Pack Mortar
2. Which standard is relevant to vapor permeation?
ASTM E96 Procedure E
3. Which backerboard should not be used in wet areas?
4. Which backerboard can be used in wet areas?
5. What should be used to prevent vapor migration in wet areas?
Low-Permeation Waterproof Membrane
6. Choose the FALSE statement
Not all waterproof membranes offer the same level of permeation performance
Large-format wet-area wall finishes still need waterproofing
Foam backerboards are acceptable substrates for large-format wet-area wall finishes
High-quality sealant or caulk is "good enough" to prevent wall waterproofingfailures for large-format wet-area wall surface finishes
7. Choose the TRUE statement
Large-format wet-area wall finishes do not need waterproofing on the substrate
Substrate selection is not as critical when using large-format wet-area wall finishes
High-quality sealant or caulk is all that is needed to address waterproofing concerns when installing large-format wet-area wall finishes
ASTM E96 procedure is the gold standard for evaluating permeation performance of waterproofing membranes
8. Choose the TRUE statement
Cement backboard needs to be waterproofed if used for wet area wall substrates
Drywall or greenboard can be used for wet area substrates and large format wet area wall surfaces
High-quality sealant or caulk joint application never needs to maintained, re-applied, or repaired
All foam board has the same low permeation performance
9. Choose the TRUE statement
Liquid and sheet membranes have the same level of waterproofing performance
All liquid membranes meet ASTM E 96 procedure E
Composite sheet membranes have many low permeation product offerings
Waterproofing is not needed when using large format wet-areas wall finishes
10. Choose the TRUE statement
Any floor covering or wall finish contractor/installer has the necessary skill setto install large-format wet-area wall finishes
Specifying “qualified labor” is one of the best means available to ensure high-quality final installations
Installation instructions and methods for large-format wet-area wall finishes are pretty much the same, regardless of the product origin
Any waterproof membrane is sufficient to address permeation
