I need to embed a metallized culvert liner on concrete. I've been told I have to paint it to avoid adhesion problems between the metal liner and the concrete. Is this true and, if so, what type of coating is best?

From Krishnan Swaminathan of Central Electrochemical Research Institute, India, Research in Protective Coating field for 27 years on July 30, 2011:
     Your version that you require a coating to avoid adhesion problems does not seem to be correct. An organic coating between metal and concrete would reduce adhesion between the two. What is the outermost metal of the culvert liner? In any case, a metallic surface is better than an organic coating surface.

From Richard McLeay of LorRich Enterprises Ltd. on June 16, 2011:
     When you say metallized, do you mean metallized or galvanized? If it is metallized, then the surface should have a "profile" due to the thermal spray process and should adhere fine to the concrete. If it galvanized, then it should be prepared and coated with an epoxy designed for this purpose.

From Mike Reynolds of MRCLLC on June 13, 2011:
     If you are speaking of spray metallizing or arc spray, then the answer is no. The concrete should be clean and sweep-blasted if possible but thermal spray adheres very well to concrete. This technology is used on concrete bridges to protect the rebar from corrosion (rebar must be in contact with metal coating)
