Seal all cut tiles according to the manufacture instructions or as directed with a flush edge free from vertical discontinuities.

Install surface applied detectable truncated dome warning surfaces on clean and dry concrete surfaces.

After placement of wet set detectable truncated dome warning surface panel, remove uncured concrete from the surface of the panel.

(b) Detectable Guide Strip - Install detectable guide strips as shown. Place according to the manufacturer's recommendation. Place abutting panels within 1/4-inch of each other and install anchors, as specified by manufacturers, along cut edge. Miter adjacent panels at locations where detectable guide strips change direction. Install detectable guide strips on clean and dry concrete surfaces.

(c) Tactile Warning Device - Install tactile warning devices as shown. Place according to the manufacturer's recommendation.

00765.42 Liquid-Applied - Protect liquid applied detectable truncated dome warning surfaces and detectable guide strips after placing and finishing according to manufacturer’s instructions.
