Cerazorb Under Tile

Prep Work

Surface Preparation
Surface must be structurally sound, clean, dry and free from dirt, oil sealers or any contaminants that would prevent a good bond. CeraZorb must acclimatize in their sealed packaging for 48 hours at a temperature of 65 degrees.

Concrete Slab
Inspect concrete sub floor for any open cracks and fill with a high grade patch. Remove any excess concrete lumps or residue that may interfere with the installation of CeraZorb. The concrete slab should be fully cured, dry, smooth, flat, and accept water penetration. Concrete must be free of efflorescence and not subject to hydrostatic pressure. A good quality concrete waterproof sealer may be required if moisture in the slab is above 10%.

Gypsum Substrates
Gypsum substrates must have a PSI greater than 2000 and must be first primed or sealed per manufacturer’s instructions.

Wood Substrates
The sub floor should be permanently dry, smooth, flat, and clean free from dirt, grease, wax, paint, oil or anything that would hinder a good bond . Plywood sub flooring should be of a good grade. Variations in floor level over 1/8” within a 3 foot span should be leveled before installing underlayment. Any nails or other protrusions should be pounded flat or removed. Sub floor should have L360 for deflection.

Bonding Material
CeraZorb is bonded to the sub floor with Impacta T-440 bond coat adhesive. Use a 1/16″ x 1/16″ x 1/16″ square-notched trowel. Apply only enough adhesive as can be covered by a 4′ x 4′ sheet.

Clean up any extra before the adhesive skins over. Impacta T-440 and the sub floor must be at 65-degree Fahrenheit.

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%. If adhesive is not transferring, apply additional adhesive. Flat trowel the CeraZorb to smooth out air pockets. Continue to install CeraZorb sheets making sure to install with edges butted tight to each other, do not overlap seams. After first row is completed, roll the mat with a 50 lb roller. Install second row with staggered seams to the first row and repeat steps above. It is recommended to wait 8-12 hours before installing tile on top of CeraZorb.

Installation of Tile, Stone or Marble
Before installation of the flooring, install perimeter isolation strips with PSA backer or cut 1″ wide by 4′ lengths off the sheet. Fasten the perimeter strips to the wall of the entire sub floor use T-700 or mastic if cutting strips. 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-modified 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 first step to tiling.

After finished floor is installed and grouted, trim the excess perimeter isolation strip flush with the floor. Prior to installation of cove or base molding seal isolation foam with either Sound Seal acoustic caulk or any waterproof acrylic caulk. Adhere the base or cove to the wall. The base board must not touch the floor to avoid sound/vibration to flank through the walls.

Prep Work
CeraZorb Underlayment and the flooring material must acclimatize, in their sealed packaging, in the room where they are installed for at least 48 hours, at temperature of at least 65ºF.
Before starting installation make sure the sub floor is permanently dry and free of dirt, dust, grease and other foreign matter. Concrete must be free of efflorescence and not subject to hydrostaticpressure. Sub floor moisture percentages should not exceed the flooring manufacturer’s or Impacta Technical Services recommendations of 5 pounds per 1,000 square feet over 24 hours;

Wood Floor Construction
Sub floor should be properly leveled, structurally sound and clean. Plywood sub flooring should be of a good grade. Variations in floor level over 1/8” within 3 feet span should be leveled before installing underlayment. Any nails or other protrusions should be pounded flat or removed.

Concrete Slab
Inspect concrete sub floor for any open cracks and fill with a high grade patch. Remove any excess concrete lumps or residue that may interfere with the installation of & HUD=RUE. The concrete slab should be permanently dry. A good quality concrete waterproof sealer may be required if moisture in slab is too high Installation under glue down hardwood CeraZorb underlayment needs to be adhered to the sub floor. Recommended adhesive:Impacta T950. Use 1/8” x 1/8” x 3/16” V– notched trowel (check for 100 transfer of adhesive and adjust to a larger trowel size of conditions require it). Start in a corner and place sheets in a brick pattern to make sure you off set the seams of the flooring. Apply adhesive on exposed area, roll back over adhesive flat trowel any air pockets, continue with other side the same way. Continue rolling out and gluing down CeraZorb in the same manner until the entire area is covered. Make sure the edges are tightly butted together, both side by side & end by end. Use a 50—100 lb roller to fully bond the CeraZorb to sub floor. After 8 hours or when adhesive is cured install glue down hardwood flooring using the ImpactaT-950 as the bond coat and follow manufactures written instructions. Install baseboard slightly off floor to avoid flanking path.

Installation under floated engineered hardwood
Start in a corner and place sheets in a brick pattern to make sure you off set the seams of the flooring. Continue the next row in the same manner until the whole room is covered. You can tape the seams but it is not necessary. Install the floated engineered hardwood per manufactures written instructions. Install baseboard slightly off floor to avoid flanking path
