Bottom Painting case: is barrier coat necessary?

[Michal]

Hi,

The previous owner did not clean / paint the boat for several years. The original plan was to sand the bottom and apply two coats of paint. Once the boat was removed from the river I got a new quote including additional sanding hours to completely remove the old paint and apply additional barrier coat before (total difference from the previous quote is $1300)

The other (cheaper) option is to just sand off as much paint as possible and apply two counts of the new paint.

Can anyone check the attached photos and advise if the extra work and $$$ are absolutely necessary?

Thanks!

Kind of depends on what you want to do with the boat and the value of the boat. Looks like a lot of paint build up in some areas but unless you are racing you can feather in the rough edges. If racing it will cause a lot of drag. I can't tell if you have blisters under the paint? So in short if you want performance strip it and coat and paint it. If you are just cruising around on a limited budget you can just sand and paint it. I saw a guy sailing with sails made out of blue tarps he got from trash containers, so nothing says you have to spend a fortune to sail.

I don't know what size boat you are talking about but if you know someone who will sand, barrier coat and bottom paint a reasonable size boat for $1300, kiss him. You just met your guardian angle.

I think the $1300 figure is on top of what he was originally quoted. It just cost me $1200 to have to have all of the old paint blasted off of my E-28/2. I'm doing the rest myself.

don't know what your long term goals are with your boat ...if you plan on keeping it any length of time i would have it soda blasted down to the gel coat ....and then repair any blisters that may be there and since your boat is only 3 numbers newer than mine you can almost bet there will be blisters if not thats great after that if you are still keeping her for long put a barrier coat on then use what ever kind of bottom paint is suitable in your area

the interlux barrier coat E 2000 ( about 2 gallons at a cost of about 250.00 materials)seems like a good product if you dont want to do the west systems method (again a bare minimum of two-three gallons at a cost of about 450.00 materials)

to answer your question yes for long term a barrier coat is necessary for short term you may get away with not doing it but that is what someone would do if they were flipping the boat they usually get out as cheap as they can ...but the next guy gets stuck that way ...i personally don't like that kind of attitude...it's likened to putting lipstick on a pig

Maybe you have barrier coat under all that paint? I'd definitely sand it down and see what the hull looks like as you get close to gelcoat. It's a lot of hard work, and is going to cost if you are paying someone else to do it. I just did mine, and figured on 3-4 days in the yard. Took me 13 days......but worth it.
