APPLICATION
Surface Preparation … Surfaces must be clean, free of oil, grease or rust and of sound quality. Remove all loose particles or residues with a jet of compressed air, sandpaper, or hard brush. Glass, metal, and other non-porous surfaces must be free of any coatings and wiped clean with solvent.

Priming … For optimum adhesion and/or joints over 1″ (25.4 mm) in width, REZI-WELD_™ LV from W. R. MEADOWS is recommended.

Joint Sizes … Proper joint design practices and application techniques must be followed for successful performance.   DECK-O-FOAM_®, or KOOL-ROD_™, or KOOL-ROD SOFT from W. R. MEADOWS may be used as a joint backing material to control sealant depth and provide proper joint configuration. For larger joints, use a non-asphalt joint filler, such as CORK EXPANSION JOINT from W. R. MEADOWS, in the joint before sealing.

A 2:1 width-to-depth ratio should be maintained.  However, in no case should joint sealant depth be less than 1/4″ (6.4 mm) or exceed 1/2″ (12.7 mm).  HS-1 SL should NOT be used in joints less than 1/4″ (6.4 mm) wide.

Cleanup … Clean tools with solvent or alcohol immediately after use. Cured material can only be removed mechanically.

PRECAUTIONS
Do not use in underwater applications.  Do not use in joints less than 1/4″ (6.4 mm) wide and/or 1/4″ (6.4 mm) deep.
