Description
Willseal 600 is a pre-compressed, self-expanding
polyurethane foam joint sealant that is designed to seal against rain, wind,
sound, draft and dust. Unlike other conventional methods, Willseal 600 is not
susceptible to breakdowns caused by excessive joint movements, joint strain,
surface contamination, aging and general tensile stress-caused failures. It does
not dry out, shrink or deteriorate. There’s no mixing, no masking, no staining
and no mess. Willseal 600 can be installed under many weather and temperature
conditions.
