Weeping Reveal

Trim Purpose

Specs, MSDS, and LEED Information for Flannery Trims & Products

Flannery’s Weeping Reveals create an aesthetic reveal in any stucco wall system. What makes a weeping reveal unique from the traditional Plaster Channel Screed is that it not only acts as a control joint, but it also acts as a “weeping” reveal. Flannery’s Weeping Reveals assist in moving water out from behind the plaster layer of a stucco system. The upper horizontal projection (or “Ground Leg”) of the Weeping Reveal is sloped to assist in draining moisture from the system similar to that of a foundation weep screed.

Install all Weeping Reveals over the weather resistant barrier (WRB) on vertical surfaces using ten-foot lengths wherever possible. Attach Weeping Reveals over the weather resistant barrier to the framing with nails, screws, or other approved fastening methods. The next horizontal layer of building paper (or WRB) should overlap the upper nailing flange above the reveal. All reveals must be cut accurately and installed with tight, neat joints. All nailing flanges must be covered with lath and all butt joints must be sealed. Manufacturer recommends that a carbide tip blade along with lubricant be used when cutting any aluminum trims.

Flannery offers prefabricated corners for intricate building designs that utilize intersecting lines and bands on exterior walls. Prefabricated corners are mitered and then welded together at their attachment flanges, then vinyl tape is applied to the back of the reveal to prevent water intrusion. Factory welded corners come with 6” legs, however custom leg lengths can be ordered.
