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 25.4 mm (1″) 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®, 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 6.4 mm (1/4″) or exceed 12.7 mm (1/2″). HS-1 SL should NOT be used in joints less than 6.4 mm (1/4″) 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 6.4 mm (1/4″) wide and/or 6.4 mm (1/4″) (6.4 mm) deep.
