ALCO SHIELD - SMOOTH
Ice and Water Protector  

DESCRIPTION
ALCO SHIELD - SMOOTH 276 Ice and Water Protector is used as a shingle underlayment on critical areas such as eaves, valleys, ridges, dormers and skylights. ALCO SHIELD – SMOOTH 276 protects roofing structures and the interior from water penetration caused by ice dams and wind driven rains.

ALCO SHIELD – SMOOTH 276 is a polymer modified asphalt membrane, fiberglass reinforced, with a smooth, skid resistance during installation.

ADVANTAGES
· Protects structure from water seepage caused by wind driven rain and ice dams
· Self-Sealing: Seals around nails, staples and screws
· Self-Adhering: Bonds directly to the roof substrate
· Skid Resistant: Dimple surface
· May be used under metal, slate or tile

PREPARATION
Sweep roof deck to remove dirt and debris. The roof deck must be clean, smooth and free of moisture. If moisture is present, it will limit or inhibit adhesion.

On re-roofing, remove all old material from roof deck area to be covered with ALCO SHIELD – SMOOTH 276. Replace any damaged sheeting. 

WEATHER CONDITIONS
Apply when air temperature is over 40° F (5° C) but below 100° F (38° C). If applied in temperatures below 40° F (5°C), ALCO SHIELD – SMOOTH 276 is stiffer and will not fully seal until it is warmed. If applied in temperatures above 100° F (38° C), it may become difficult to remove the release poly backing. If this situation should occur, move product into a shaded area until cool. Once cooled, the release poly backing can be easily removed.

INSTALLATION
ALCO SHIELD – SMOOTH 276 is applied directly to the surface of the roof. see carton for complete instructions.
COLD WEATHER APPLICATION: Mechanically fasten membrane to position until it has bonded to the roof.
