SHOWERCORK™ INSTALLATION
Installation of the Showercork™ is similar to typical ceramic or mosaic tile installation using the glue and grout method.
PREP: The existing substrate should be clean. Remove old adhesives, loose or weak concrete, dirt, debris, and any other contaminant that may impact the bonding of the Showercork™.
SUBFLOOR: Apply on (1) fully cured and smooth concrete; (2) a tile backer; or (3) a plywood subfloor – a minimum of 1” thick over joists spaced a maximum of 16” on center.
NOTE: In “wet” applications (such as, a shower, spa, etc.), it is important to use a “water-proofing and crack prevention membrane” (such as Custom’s RedGard), followed by the “thinset” installation method.
STEP 1: Spread evenly a flexible ceramic thin set mortar, or an oil modified urethane adhesive across the prepared cement substrate.
STEP 2: Place carefully Showercork™ sheets next to one another, cutting with a sharp utility knife where needed. Apply pressure evenly to sheets to ensure they are level.
STEP 3: If staining Showercork™, do so now. A water-based wood stain, such as Minwax. All unfinished Showercork™ should receive 2 coats of a waterbased urethane finish, such as Bona Kemi’s Traffic before grouting.
STEP 4: Apply a “flexible” sanded grout with a rubber trowel, making certain that all joints are filled. The finished joints should be uniformly smooth, without any voids or low spots.
STEP 5: After the grout is completely cured, finish the installation by evenly applying two additional coats of polyurethane.
MAINTENANCE: Sweep or vacuum and dry mop (using mild soap and water). Use a restorative cleaner compatible with your finish for routine maintenance. In addition to simplifying cleaning, this will prolong the time between refinishing. Refinishing should be done every 5-10 years, or whenever wear is visible.
