My canal boat has been coated sometime in the past with a zinc protective coat. This is causing serious issues with paint adhension. Is there a product available that would enable the paint not to bubble off? Any suggestions gratefully received. Thank you.

Emma, I have asked the Editor to get a paint expert to answer this. I seem to remember that a primer called Gavafroid advises on what type of paint has to be used for the next coat but I fear it might be a total paint strip and start again job. It might help if you could find out exactly what products you have. Tony Brooks

Hallo Tony, Thank you for the reply. I have no idea as to the zinc coating itself but the paint system last used was Blakes. That's all I know! Not terribly useful I am afraid. To be honest hubbie and I are expecting to have to blast the top side back which obviously is not ideal!! Thanks again Emma

Dear Emma, If you can hold fire for a couple of months you may well find Phil Speight answers your question in the magazine rather than on the forum. I doubt you will need to get it sand or shot blasted because I think a horrible device in an electric drill called a scabler (spelling?)will remove most of the paint so a fairly quick go over with an abrasive disk on a disk sander will be adequate preparation. The zinc rich paint I have in mind requires (from memory)overcoating with a chlorinated rubber paint (Zinc & oils do not get on well together) but to remove the ordinary paint with a paint stripper will be expensive and the stripper will probably also remove the zinc paint. At this stage it is important to point out that I am not talking about the zinc oxide or zinc chromate primers that are designed to go under one pot coach paint (oil based) systems. I think you should contact Blake's technical department and ask their advice. They even publish a booklet about painting boats so should be helpful. Tony Brooks
