Daraflex Fibre



DARAFLEX FIBRE is a polymer modified anionic bitumen emulsion containing a synthetic fibre, the fibre enables the product to form a continuous waterproofing layer without the inclusion of a membrane.  Once completely dry the product becomes highly resistant to swelling or re-emulsification, a problem associated with other water based systems.  The product us supplied in 25L and 210L drums and should be used within two months of the date indicated on the container. Thorough stirring is required before use and the container must be protected against frost.
