frp, tile, plywood with, like above, lots of urethane. not drywall, don't even care if it's painted, its not "non absorbent", metal surrounds with a good painted surface (toilet partitions) brcik or block painted with block filler then a good paint. must have block filler first. there are a tone of "exceptions to the rule", i may not agree with them

Drywall can be substrate. You no follow Milton's rule.

What about vinyl backed wallpaper?

FRP (Fiberglass Reinforced Panel), stainless steel, ceramic tile or other approved

 

[Sanfords]

responses very

you are right

 

[Examiner]

The finish has to be non-absorbant not the substrate to which the finish is attached.

There is the Boat Test (or as brudgers might call it, a Duck Test) where you see if it floats, and then there is thee Boat Test (ASTM D 779 and ASTM D 226) which deals with how much bulk water can pass through it.

Water Resistance - ASTM D 779 “Boat Test” Specimen Approximately 5 in. (127 mm) diameter One side of test specimen in contact with water, while the dry side contains a dry indicator powder. Examine time for water to pass through specimen Report water absorption in minutes 10 minutes minimum, no water passage.

shall have a smooth, hard, nonabsorbent surface,

It also has to be hard and paint ain't

Witch test are you talking about?

 

[Big Mac]

But the substrate needs to be a type of material not adversely affected by moisture such as water resistant gwb, concrete board, etc.

 

[Papio Bldg Dept]

Witch test are you talking about?

Yes, that one.

 

[mtlogcabin]

But the substrate needs to be a type of material not adversely affected by moisture such as water resistant gwb, concrete board, etc.

I always believed it was more of a sanitation/health (germs) issue then the material being adversely affected.

mtlogcabin,

I believe that it is both!........Initially yes, I agree with your perception as

well, that the requirement was born out of sanitation issues, but as we all

know, that if a surface won't hold up to a "wet environment", it won't

remain long enough to have the sanitation issues as well.
