Two spray heads H1, H2 are present for use in lining a pipe P, the heads H1, H2 being arranged in line and arranged to apply composition, from the same supply line, in succession to the inner surface of the pipe P. The heads H1, H2 are supported by a carrier 6 which travels inside the pipe. Hose supply lines 3A, 4A feed into an inline static mixer 8 from reservoirs 3, 4 of unhardened resin and a hardener therefor. Use of two heads H1, H2 ensure application of two layers of lining in succession thereby guaranteeing that lining is complete. Each head comprises a floor 10 and with a side wall 11 shaped to direct atomised lining composition outwardly of wall 11. A plurality of heads may be connected in series. |
