SeraPool Natural Cotto Porcelain Slot Overflow Coping

Custom order: produced for your project and shipped direct from the factory. Lead time is confirmed with your quote.
SeraPool Natural Cotto Porcelain Slot Overflow Coping is the deck-level coping for slot overflow (deck-level / rim-flow) pools: pool water flows over its sloped face into the slot behind it, while the top stays flush with the deck. It is part of the SeraPool Natural™ Outdoor & Pool Collection, where the pool interior, coping, grates and deck are specified as one porcelain system.
Cotto is a terracotta-red porcelain surface inspired by traditional cotto. Pool coping, grates and deck tile are produced separately, so slight tonal differences between them are normal for this natural look; blend pieces from several crates during installation.

Installation notes
- Set on a sound, level bond beam with a C2TE S1 deformable cementitious adhesive (EN 12004) or an ANSI A118.15 improved modified mortar, fully back-buttered with no voids.
- Check the 5% slope and the slot width against the overflow detail on the drawings before setting; coping and edge tile set the final water level.
- Use 1/8 in. (3 mm) joints and a flexible, pool-rated grout. Leave a flexible, sealant-filled movement joint between coping and deck tile and over structural joints (TCNA EJ171).
