Figure 80-90 square feet with the 1/4x14 trowell for the backer.
45 feet using the 1/2x1/2 trowell when installing the slate.

I swear it's like you were reading my mind!!!
No work on the floor today. The weather was beatiful outside, so I took advantage of it and got caught up on some neglected yard chores.
While outside working though, I got to thinking this exact question. "How big of an area will a bag of thinset cover?" As usual, you're full of great info, thanks!!!

Use acrylic modified for the whole job, not just the slate.
Are you using a modified thinset with the additive in the powder? The "just add water" kind?
you may have a s much as 400#'s of thinset left over from the backer install.

The stuff I picked up for the slate:
PRODUCT DESCRIPTION
PRO M-BOND ULTRAŽ 918 is used as a
professional grade bond coat for setting
high lug, absorptive, semi-vitreous, vitreous
ceramic tiles and natural stone for service
in residential and commercial use. It is used
in a mortar bed from 3/32" to 3/16" (2.4 to
4.8 mm) after the tiles have been properly
embedded. PRO M-BOND ULTRA 918 has
excellent water and impact resistance, is
water cleanable, non-flammable, good for
exterior work and requires no soaking of tiles.
PRO M-BOND ULTRA 918 mortar is not affected
by prolonged contact with water, but does
not form a waterproof barrier. PRO M-BOND
ULTRA 918 provides a permanent installation
with higher bond strength and lower material
and labor costs than conventional Portland
cement mortar beds.
The salesman at the tile store said that The C-Cure Thinset Mortar will work just fine with the backerboard, especially since I'll be nailing it in place in addition to the thinset.
PRODUCT DESCRIPTION
THINSET 911 is a factory blend of Portland
cement, sand and a unique blend of special
additives. C-Cure THINSET 911 produces an
excellent bond with greater coverage than
conventional dry-set mortars for the
installation of ceramic tile.
BASIC USE
THINSET 911 is used as a bond coat for setting
absorptive, semi-vitreous and vitreous
ceramic tile for service in residential and
commercial use for both floor and wall
installations. It is used in a mortar bed from
3/32" to 3/16" (2.4 to 5 mm) after the tiles
have been properly embedded. THINSET 911
has excellent water and impact resistance, is
water cleanable, non-flammable, good for
exterior work and requires no soaking of
tiles. THINSET 911 mortar is not affected by
prolonged contact with water, but does not
form a waterproof barrier. THINSET 911
provides a permanent installation with
higher bond strength, however, requires lower
material and labor costs than conventional
Portland cement mortar beds.
AREAS OF USE
Suitable backings, when properly prepared,
include plumb and true masonry, concrete,
gypsum board (dry interior walls only),
cementitious backer units, cured Portland
cement mortar beds, brick, ceramic tile
and marble.
Will this be adequate?
Also, you mentioned an "additive". Is there something else I should get to add to this stuff, or is it good right out of the bag?
