Drywall experts question

[Richard]

If you went to a drywall supply house and bought some sheets of

http://www.gp.com/build/product.aspx?pname=DensArmor%c2%ae+Plus+Interior+Wallboard&pid=4659&hierarchy=pc

for $22.40 a sheet (4x10, 5/8" thick)

And when you ran out, needing more supplies, you went back to the SAME place, asked for the SAME thing "mold resistant drywall", if they gave you this ($25.56 a sheet)

National Gypsum Company: Gold Bond, ProForm, XP Wallboard, PermaBase Products and More

Would you feel you got the "same" thing (mold resistant) or would you feel you suffered a mixup?

Another fact: The Densarmor is WHITE and the XP stuff is BLUE. Upong seeing the blue stuff loaded into the truck, I specifically walked BACK inside to talk to the sales desk, asking if I bought the right stuff since it was different. I was told by them that "it's the same thing".

Upon installing it, though it might technically be the "same thing" from a mold perspective, it sure is a different material to work with (feels a lot softer & like it's made up of compressed newspaper)

(not denigrating it, just making comment that it's NOT "the same thing", using a strict definition on "same")

So, today, I wait on the manager to get back and give me a call.

I don't know if I should shut up & be happy, or be a little bulldog & take it all back (the blue XP stuff) and have it swapped out for the white stuff.

Any thoughts...

Second comment: This place only carries 20/30 sheets of this "mold resistant" stuff since it's so expensive and has little demand. Seems to me if they don't stock THAT much of it, then they SURELY are NOT going to be stocking it from DIFFERENT manufacturers? (ie, it's NOT the same thing and I've installed a lessor product)

Is this XP stuff the "same thing" as the Densamor stuff as far as my (main) concerns of mold resistence since it's going into a below grade full bath?

Richard,
$20 a sheet sounds awfully expensive. I think I paid $11/sheet for 1/2" paperless (Densarmor). Why did you use 5/8"? The only place I used 5/8" in my bathroom is on the ceiling to minimize sagging due to the 20" spacing of the rafters, and it was just the plain 5/8" type, not the moldproof (didn't see the need for it on the ceiling).

I think they said only the 5/8 made... (or perhaps it was the only size they carried)

None the less, this place was the ONLY place in town that had it and (given my allergies) I want to do EVERYTHING posible I can to help insure my fight against allergens.

(I realize that nothing is 100%)
