Guidelines for the Installation of Sure and Secure Safety Stair Treads or Nosing into New Concrete or Steel Pan Filled Stairs:

• The use of very large aggregate in the concrete mix may make placement of the safety nosing difficult.

• Safety nosing placement may be difficult in concrete with very slow slump.

• Place concrete into the stair forms or steel pans as quickly as possible; schedule pours so as to install the metal safety nosings quickly before initial set of concrete occurs.

• Puddle the concrete, tamp the safety nosing to insure proper concrete formation around the anchors.

• Remove protective tape (if used) as soon as practical.

• Order nosings or treads well in advance of the pour or installation date.

• Close stairway after pour; permit no use for 24 hours.
