I am building a commercial steam room starting out with cinder block walls. I noticed you product mapelastic waterproofing (http://www.steamsaunabath.com//catalog/product_info.php/cPath/64_104/products_id/202542). Can I use this over the cinderblock and is it suitable for a commercial application? How much would I need to cover a 8x10x8 room?

You can certainly use Mapelastic waterproofing on your cinder block walls and, in fact, it is highly recommended. Cinder block is an extremely porous material so you should figure about 50 square feet of 2-coat coverage per gallon in your case.

Your room consists of:
(2) 8x10 walls @ 80 sq. ft. each  = 160 sq. ft.
(2) 8x8 walls @ 64 sq. ft. each    = 128 sq. ft.
(1) 8x10 Ceiling @ 80 sq. ft.        = 80 sq. ft.
(1) 8x10 Floor @ 80 sq. ft.           = 80 sq. ft.

So 8 gallons should suffice to cover the room (9 gallons if you are also doing the floor).

is this the only way to waterproof a steam shower? I don't have cinderblock on the walls in the room that we are adding for steam. Will the same material work for "greenboard", as my contractor calls it?

Designed for installation under ceramic tile or stone in residential and commercial steam shower environments, Mapelastic AquaDefense is an advanced liquid-rubber waterproofing which bonds to many surfaces and provides a continuous barrier to protect against moisture and water related concern.  Speak with a Steam Bath Installation Specialist to review your installation.
