Dispensing apparatus is provided for use in dispensing a fluid lining material onto the interior wall surfaces of a conduit. The dispensing apparatus includes at least one reservoir for the containment of at least one fluid, dispensing outlet means communicating with said at least one reservoir for dispensing fluid therefrom and a rotational head member for directing the dispensed fluid from said dispensing outlet means in a required direction onto the walls of the conduit. The rotational head member has an opening which faces the remainder of the apparatus and said head member is capable of undergoing reciprocal motion relative to a further part of the apparatus in use to allow multiple layers of fluid lining to be provided in a single pass of the apparatus through the conduit. A directional member is provided in the recess portion and fluid dispensed from said dispensing outlet means impacts initially with an outer surface of said directional member prior to flowing out of said recess portion.
