ARDEX TLT Building Panels
Installation Guide for Walls
ARDEX TLTTM Building Panels can be installed over wood and metal studded walls horizontally or vertically by using the galvanized ARDEX TLTTM Screws & Washers. All vertical joints must be supported by suitable, load-bearing framing. Maximum spacing of studs is 16″ on center.
**STEP 1**
Place ARDEX TLTTM Screws and Washers 12″ apart vertically and 16″ apart
horizontally. It is best when applying the screws to create a slight
depression in the board to reduce any buildup at the screw. Vertical seams
must be staggered.
**STEP 2**
Seam Waterproofing – Method 1 (ARDEX TLTTM Seam Tape)
Cover all seams and screw/washer dents with the recommended ARDEX modified
thin-set mortar and ARDEX TLT Seam Tape. Make sure all seams and
screws/washers are fully covered with a minimum 2″ overlap (approximately a
4.5″ patch to cover washers). Use a grout float to remove any excess thin-set
and air pockets.
Seam Waterproofing – Method 2 (ARDEX CA 20 PTM)
Cover all seams and screw/washer dents with ARDEX CA 20 PTM. Flatten the
excess adhesive with a spackle knife. Make sure all seams are fully covered
for a watertight seal.
For Steam Showers – Method 3 (ARDEX TLTTM Waterproofing Membrane)
ARDEX requires a layer of TLT Waterproofing Membrane to be installed over the
TLT Building Panels.
