BONDING MATERIAL
CeraZorb can be bonded to the sub fl oor with Mapei Ultracontact or UltracontactRS bond coat adhesive or equivalent (recommended,
but not sold through WarmlyYours). Use a 1/8” x 1/8” x 1/16” V-Notched trowel. Apply only enough adhesive as can be covered by a 2’ x
4’ sheet. Clean up any extra adhesive before the adhesive skins over. Mapei Ultracontact or UltracontactRS and the sub fl oor must be at
65ºF (18ºC).
INSTALL CERAZORB
Set the CeraZorb into the adhesive while it is still wet. Do not allow adhesive to skin over. Lift a corner periodically to see if the adhesive is
transferring 100 percent. If adhesive is not transferring, apply additional adhesive. Flat trowel the CeraZorb sheets, making sure to install
with edges butted tight to each other and ensure that you do not overlap seams. After fi rst row is completed, roll the mat with a 35 lb.
roller. Install the second row with staggered seams to the fi rst row and repeat steps above. It is recommended to wait 8-12 hours before
installing tile or stone on top of the CeraZorb.
INSTALLATION OF TILE, STONE, OR MARBLE
Before installation of the fl ooring, you may choose to install CeraZorb 1” wide by 4’ lengths cut off the sheet to act as perimeter strips around
your room (optional). To install, fasten the perimeter strips to the wall of the entire sub fl oor using Mapei Ultracontact or UltracontactRS or
equivalent. Make sure to follow applicable ANSI A. 108/A. 118/A. 136 for proper installation of ceramic tile.
When applying tiles to CeraZorb, always use a polymer-modifi ed mortar meeting ANSI A118.4 or A118.11 standard. It is recommended to
key-in/burn-in a thin layer of thin set into the surface of CeraZorb as a fi rst step to tiling.
After fi nished fl oor is installed and grouted, trim the excess perimeter isolation strip fl ush with the fl oor. Prior to installation of the cove or
base molding, seal isolation foam with any waterproof acrylic caulk. Adhere the base or cove to the wall. The baseboard must not touch
the fl oor to avoid sound/vibration to fl ank through the walls.
