Color finishes are applied in-house with a state-of-the-art powder-coat finishing system that offers a superior UV and slip-resistant finish. TufTile offers a 10-year no-rust warranty on powder-coat galvanized steel tiles.

8. What is the dome spacing dimension?

TufTile in-line truncated domes have a North-South & East-West spacing of 2.35-inches, in compliance with ADA specifications.

9. What does “Avoid the Void” mean?

TufTile’s flat back design detectable warning product prevents pockets of air and moisture between the tile and concrete. This results in a stronger bond between the concrete and tile and prevents freeze-thaw issues. This product feature is unique to TufTile and is what we like to call “avoid the void”.

10. Can surface-applied TufTile be installed on asphalt?

Yes, TufTile has a specially designed anchor that enables tile installation in asphalt. Contact technical support at 888-960-8897 for installation information and ordering.

11. How long does the tile have to set before pedestrians can walk on it?

Foot traffic can begin immediately when the tile is installed using the surface-applied method. For wet-set installations, foot traffic should be avoided until concrete is fully cured. See concrete manufacturer’s instructions on cure times.
