||Custom colored acrylic latex caulk with silicone. ColorFlex is designed for corner and perimeter caulking of decorative surfaces. After the component (counter, vanity, bath surround, etc.) is installed and the laminate seams have been filled with SeamFil, ColorFlex is used to seal the inside corners and perimeter of the component. Where flexibility is needed, ColorFlex is perfect for filling gaps and sealing places where components meet the walls, floors, cabinets, tile or insets.
