Thank you for your question. please see the install guidelines below.
asten to subfloor with 1-1/4" USG Durock™ Brand Tile Backer Screws for wood framing (or
equivalent) or 1-1/2" hot-dipped galvanized roofing nails spaced 8" o.c. in both directions
with perimeter fasteners at least 3/8" and less than 5/8" from ends and edges. Drive nails and
screws so bottoms of heads are flush with panel surface to ensure firm panel contact with
subfloor. Do not overdrive fasteners. Finish joints with USG Durock™ Brand Waterproofing
Membrane Band (5" wide) adhered with unmodified thin-set mortar and treat fastener
penetrations with USG Durock™ Brand Sealant. Apply only enough sealant to sufficiently cover
the fastener head and then strike flush using a 1" putty knife in order to minimize spread of
sealant. For applications not requiring waterproofing, pre-fill joints with unmodified tile-setting
mortar and then immediately embed USG Durock™ Brand Tile Backer Tape and level joints.
Do not use USG Durock™ Tile Backer Tape for waterproofing or steam room applications. Use
unmodified thin-set mortar to set tiles.
C. For wall application, fasten USG Durock™ UltraLight Foam Tile Backerboard panels to framing
with specified fasteners. Drive fasteners into field of panels first, working toward ends and
edges. Hold panels in firm contact with framing while driving fasteners. Space fasteners
maximum 8" o.c. for walls, with perimeter fasteners at least 3/8" and less than 5/8" from ends
and edges. Drive nails and screws so bottoms of heads are flush with panel surface to ensure
firm panel contact with framing. Do not overdrive fasteners. Approved fasteners include:
USG Durock™ Tile Backer Screws for steel framing (or equivalent), 1-1/4" and 1-5/8" for 14- to
20-gauge steel framing; USG Durock™ Tile Backer Screws for wood framing (or equivalent),
1-1/4", 1-5/8" and 2-1/4" for wood framing; nails 1-1/2" hot-dipped galvanized roofing nails.
Finish joints with USG Durock™ Brand Waterproofing Membrane Band (5" wide) adhered with
unmodified thin-set mortar and treat fastener penetrations with USG Durock™ Brand Sealant.
Apply only enough sealant to sufficiently cover the fastener head and then strike flush using a
margin trowel or similar in order to minimize spread of sealant. For applications not requiring
waterproofing, pre-fill joints with unmodified tile-setting mortar and then immediately embed
USG Durock™ Brand Tile Backer Tape and level joints. Do not use USG Durock™ Tile Backer
Tape for waterproofing or steam room applications. Use unmodified thin-set mortar to set tiles.
D. Panels are cut to size by scoring both sides and snapping using a knife and straight edge.
E. For 1", 1-1/2" and 2" thick board, fasten with 2-1/2", 3" and 3-1/2" (respectively) corrosionresistant
wafer-head screws with a minimum head diameter of 3/8" (10 mm).
