This floor system is built for problem floors that demand control, not guesswork. By pairing Berger-Seidle ExoBlocwith Berger-Seidle CeramicStar, this system addresses contamination, movement, and wear before they turn into callbacks.

ExoBloc is a highly elastic, waterborne sealer designed to minimize side bonding, block salts and contaminants, and tolerate movement commonly found in old houses, wide plank floors, radiant heat installations, and entryways. It creates a controlled interface between the wood and the finish without building a brittle film.

CeramicStar is a ceramic-reinforced, two-component waterborne finish engineered for exceptional abrasion resistance and long-term durability. When applied over ExoBloc, it delivers a tough, clear, professional surface that holds up under real traffic while maintaining predictable application and fast return to service.

Why this system is used

• Controls salt, mineral, and unknown contamination

• Reduces risk of side bonding and panelization

• Tolerates seasonal movement and wide plank floors

• Delivers high wear resistance with a clean, non-ambering finish

• Designed as a sealer + finish system, not mismatched products

Best used when: old floors, entryways, pets, radiant heat, wide planks, or unknown floor history are involved.
Not ideal when: a low-cost, cosmetic-only solution is the priority.

At Ground Floor Supply, this system is recommended when failure is expensive and prevention matters. It’s not about the strongest product on the shelf — it’s about choosing components that work together so floors perform long after the job is done.
