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:Applying Showercork Adhesive

Spread evenly a flexible ceramic thin set mortar, or an oil modified urethane adhesive across the prepared cement substrate.

STEP 2:Installing Showercork Sheets

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:Cutting Showercork to fit

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:Applying Grout

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:Cleaning off Grout

After the grout is completely cured, finish the installation by evenly applying two additional coats of polyurethane.

Applying urethane topcoat

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.
