Bostik Colourseal is a strong, highly flexible (+/-20-25%), anti-fungal, mildew resistant acrylic gap filler. Colourseal is designed for internal and external applications for horizontal and vertical sealing requirements where a flexible sealant is required. Colourseal offers excellent adhesion properties when cured and is more flexible than conventional acrylic gap sealants with minimal shrinkage.
