    This ^^^^, and...

     

    What made you choose floor paint rather than bilge paint?

    I’m thinking you’re right - the vactan does need to be left longer... there doesn’t seem to be any instructions readily available about overcoating time though ? 

     

    And floor paint due to cost - bilge paint isn’t cheap! As an overcoat to a vactan’d surface I thought the heavy duty floor paint would be a good option and have seen some other good reviews from use in bilges. It’s oil and chemical resistant and suitable for use on metal.

    I would suggest a proper bilge paint like Danboline. Some floor paints are probably ok, but others are just not suitable for a steel bilge on a boat, so its a big gamble.

    Thanks Dave

    In an ideal world that or owatrol is what I’d be using but it’s pricey stuff. I know in most cases you get what you pay for but with such a large area to eventually cover I opted to spend on the vactan and save using the floor paint which is less than half the price. Seems to have done the trick in most places so far ?

    Suggest you live with it for the next 5 months and then grind it out, read the instructions, paint it again in accordance with the instructions.


    Realistically I’m probably not going to grind it all back again - it’s taken a lot of work to get to this stage given the state it was in prior to any work - and I’m talking sodden with slabs of rust 5mm thick (don’t worry I’m overplated!) 

     

    As it’s localised I was hoping to get away with wire brushing affected areas then spot treating with vactan (when conditions are ok) then more of the heavy duty paint over that.

    Have you done any angle grinding?  The specks of steel will rapidly tarnish if they are not cleaned off, before or after painting.


    Yes there has been angle grinding nearby since painting so it may well be that - guessing I would just wire brush back and treat again? 
     

    Also the rusting specs are localised and not over the whole treated area.

    4. One coat of Vactan, left to cure for a few hours at least.

     

    This is your problem.

     

    Did you read the instructions? Absolute minimum 24 hours in hot summer, otherwise 48 hours. 


    Was done end of Aug so warm enough - I’m all too aware of vactan being ineffective below 10 degrees! 
     

    Didn’t realise 24-48hrs required prior to overcoating though - instructions don’t state anything about overcoating time but it would make sense to leave it to cure longer as you’ve said. 

  5. Hello! Just after some opinions or advice on why I might be seeing rust spots come trough my bilges treated as follows: 

     

    1. Significant chunks of rust removed

    2. Wire brushed and scraped down clean as much as possible

    3. Wiped down with white spirit, left to dry

    4. One coat of vactan, left to cure for a few hours at least

    5. One or two coats of leyland heavy duty floor paint 

     

    All done a matter of months ago and now tiny speckles of rust have appeared through the paint. Any ideas why and what my next steps could be?

     

    Thanks in advance for any help!!
