    Sorry.... I know this has been asked about a million times already and I wish could find the posts so I wouldn't have to ask it again.

    About how much bottom paint is required per coat for a W32?

    Mike: 
    Of course it depends on how thick etc but I usually rough sand the existing and apply one good coat and I recall using a gallon and 2 qts with a little left over.  
    It has been 3 years so memory may be off...

    Mike,

    I've always bought two gallons of hard paint (non-ablative). Good coverage without skimping and about a quart or less left over.

    I know there are variables (brushed or rolled etc.) which makes it hard to estimate.

    That's my problem. I'll be starting from a 'bare hull' and looking to apply oh, at least 2, maybe 3 good coats of ablative.

    Sounds like I should factor about an average of 1 1/2 gallon per coat. More to start, maybe less at the end.

    "Bare hull" does this mean gel coat?  if so look in to applying barrier coat first.

    Essentially, since I'm switching from a hard paint to an ablative.

    so yep... that too

    I just put only ONE gallon of Micron 66 on my bottom. Practical sailor just did a review of bottom paints and it seemed to be the best for my purpose of actively cruising. I plan on doing a shake down cruise for a few months and so I wasn't all that concerned about having a thick coat as I will be putting a new coat on after I launch later in the year. I will let you know the results in a few months to see if I made the right decision or not. What I wanted to convey was, that this paint was like no other paint I have ever come across. It really did a number on the rollers and brushes I was using by tearing them all up and I had to use 2 face masks mitigate the odor.

    Just a small side note about using a face mask while painting...  Be aware that there are different types of masks for different threats.  If you are dealing with dust (sanding) you need a system that will keep particulate matter out.  If you are dealing with fumes (painting), you need a system that filters out the vapors (organic compounds).  They are different.  The little hospital type masks that you buy at the local hardware stores will not protect you.  You need either a full face mask or half mask (depending on the project) that has replaceable filter cartridges - and use the proper filter cartridge.
