Cork Mosaic Tile Installation Guide

The installation or setting of the cork mosaic tile is similar to a typical ceramic or mosaic tile installation using thinset and grout.

PREPERATION: 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 cork penny round tile.

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 or other prepared surface.

STEP 2.

Place carefully cork tile 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 cork penny round tile, do so now using a water-based wood stain, such as Minwax. All unfinished cork tile 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.

Carefully clean off the grout with a grout sponge and make sure to remove all residual grout and haze.

Maintenance

Cork mosaics are a natural product and although incredibly durable will last far longer and clean up much easier with the application of a protective finish.

FINAL STEP.

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.
