Performance Characteristics:

� Exceeds the ASTM Specification C-834.

� Tack free in 30 minutes.

� Provides a tight yet flexible seal

� Paintable with latex or oil-based paints.

� 35 Year Durability Guarantee

� Easy water clean-up.



Surface Preparation & Application:

� Surface must be clean, dry and free of all dirt, dust, grease, old caulk and debris.

� Cut nozzle at 45º angle to desired bead size. Load cartridge into caulking gun. Fill gap with sealant.

� Smooth the bead of caulk for a neat finish.

� Clean up excess caulk with a damp cloth before it skins over (15 minutes).

� Reseal for storage and reuse.



For Best Results:

� Caulk in temperatures above 40ºF and rising.

� Store caulk away from extreme heat or cold.

� Do not use for below waterline applications or marine or automobile applications.

� Do not use for filling butt joints, surface defects or for tuck pointing.

� Joint width should not exceed 1/2�. If joint depth exceeds 1/2", use foam backer rod.

� Allow caulk to dry at least 2 hours (longer in cool or humid conditions) before painting with latex or oil-

   based paints.

� Do not use if rain or freezing temperatures are forecasted before full cure can occur. Cold weather and high

   humidity will slow down cure time.
