Re: Painting a boat on a budget....Need help

Bond-o has it right. Most all of the bottom paints will not prevent osmosis blistering except one and that's Interlux VC-Performance. That's what it was called when I bought it but the name has changed since. This however is not an anti-fowling paint like you currently have. The only way you'll ever prevent blistering is to buy yourself a hydro-lift. My brother and his buddy learned that lesson the hard way with their 65,000.00 Nautiques. Fortunately, osmosis blistering is not structurally damaging and can be repaired back to original conditions. Not something you want to do every year mind you but it can be fixed.

In short, it doesn't really matter what you use on the bottom with a glass boat, if you leave it in the water for extended periods of time you're going to risk blisterning.

Re: Painting a boat on a budget....Need help

My Question is for paiting the boat with rustoleum. I planned on applying three coats waiting a day between coats and sanding in between. Is this correct or do I apply two heaver coats. Thinner coats are better, In my opinion and in the opinion of Rustoleum

I read the car forums and they suggest thinning to 40-50 percent and applying 5 coats which seems crazy to me. What do you recomend. I will be using a tack cloth between every coat. Rustoleum recommends thinning no more than 30% and I would say 3 coats is adequate, maybe 4.

I also have questions regarding whether to use a seperate roller to go over the rustoleum and remove air bubles or use a badger hair brush like interlux perfection recomends. Sorry for the hundred questions. I recommend a semi-dry foam roller for the second roll over. I dip it in thinner and then squeeze out ALL the excess and towel dry.

This is what I recommend.

Final question(no gauarantees lol)
You go over the freshly applied paint directly after it was applied or wait a little bit. Do i paint say a five square foot area then go back and smooth that area out or do it immediately after. Thanks again

Yeah, that IS the way the MFG's suggest doing it, but the guys here on iBoats have found that the Roll n' Roll yields superior results with FAR less bush marks or overlap tracings. DREWPSTER and others experience tell the tale.

Did you mean Roll and Tip? Or there another method I'm not familiar with?

No, I meant the MFG's say Roll and tip, but the guys on here, me included, say to Roll n' Roll like the video's I posted.

I like that method too! I've used it with excellent results. I used the really hard little hot-dog style rollers and changed them frequently. Even the ones rated for epoxy that I found tended to break down pretty quickly. West Marine was selling the larger epoxy rated rollers but I didn't have much luck with them. I did cut them up and use them in the corners. That worked very well.

I will have to look into that. I have not bought my badger hair brush yet. I will try your way.

Its hard to tell in the video but about how much time did he allow from rolling to flattening. Is it a time thing or can you tell when the paint starts setting up? Is five minutes the standard amount to start out then tailering it to you specification.

Gloss white. Not trying to attract attention to old betsy but make it presentable looking. I appreciate the help guys.

When I do it I roll about two feet then go back and flaten it out then another two feet and flatten. You have to keep a wet edge at all cost.

Re: Painting a boat on a budget....Need help

Conditions vary, but you want the paint to just start to tack up a bit before you hit it with the dry roller. To wet and the dry roller will just take the paint off, to dry and you won't get the bubbles out. You kinda got to experiment a bit and you'll get on it. Won't take long and you'll be a PRO.

Agree, I used a wet but unloaded roller and I didn't have any problems flattening before it tacked.

When you say wet I assuming you mean dipped in thinning fluid. then all the excess fluid squeezed out and then towel dried the roller. This is what woodonglass suggested. So i guess it should just contain a small amoutn of thinning fluid. Just enough that it is not dry but not to much that its wet. Seems this is another area I will have to get a feel for because there is no exact science to it. Should be easy though

I am going to try and flatten with a roller. If i find it unsuccesful I will go get the badger hair brush and try it out. Should be a good learning project.

Do you guys suggest sanding between coats? I am defenitly going to sand between primer coats but if the paint coats look fine should I sand or just leave it alone? 300 grit should be ok to sand in between the coats right.

Re: Painting a boat on a budget....Need help

I just use a Scotch Brite pad and water to sand between coats. This will Knock down any dust nubs you might have but is very NON aggresiive to the paint. Towel Dry, Tack Rag it with a little thinner let it dry a few minutes and Roll it again.

I worked on my boat all weekend and figure I would give an update.
I used rustoleum fiberglass primer. Its part of their marine series and I bough two quarts of this stuff. When you pop the lid off of the can you are greated with brown water on top and what looks to be playdough on the bottom. After mixing for 10 minutes you now have something that resembles a very thick milkshake. I did not thin this primer at all; I applied it directly after mixing it in the can. I applied my first coat a primer a little prematurely. I thought I was done my bodywork but as the first coat of primer revealed I was not. I had to do a lot of scratch repair and apply a little filler hear and there.

I next applied the second coat of primer and was once again greated by the playdough. I rolled the primer on with the four inch hot dog rollers. I only used around 3/4 of a quart of paint to paint the entire exterior from the rub rail to the bootom paint and the transom including the storage area. I was very happy with the coverage of the rustoleum paints. Boat is a 20 foot cubby cabin grady white with waist high gunals( i am not sure how to spell it maight be gunnels?).

I used rustoleum professonal gloss white paint with 15% thinner and the magic hardener in it. I applied the first coat of paint and found it difficult to roll the paint on and then roll out the air bubbled because my boat is not flat on the sides. It has the fake wood look(dont remember what its called) so its very time consuming to get all the edges covered fully in paint; looks like lap board siding. Then disaster struck I dropped my air bubble removing roller in the grass twice. I was not having any luck using two rollers at this point so I only used one roller from hear on out. I adopted a new technique using this roller as well.

My new technique was to roll the paint on as usual. Then basically I would have to roll the area several times after the paint had time to set tup and I had a relatively dry roller. I basically combined the functions of two rollers into one. This worked remakable well. i had zero runs or roller marks but I did get some very ligth orange peel. My brother and father in law came out and were amazed with how it looks. I am going to do one or two more coats depending on how my second coat looks. I am very happy with the results and hope that the orange peel settles some as the paint dries. after my second coat if there is still orange peel can I do anything about removing most of the orange peel. I am thinkign about trying with the badger brush for my next coat though.

I think it looks beautiful especially for a 32 year old boat. I did not get any pictures because as soon as I finished it felt like it was going to rain so I hurried the boat back into the garage to dry. By the way the father in law was so impressed he asked me if I could help him with his 28 foot boat. I guess I impressed him. I should apply my second coat tonight. Sorry for the thousand word response but I was trying not to forget any details for people wanting to try this on their boat.


EDIT:
One thing I forgot to mention is that I went to my brothers house directly after painting the baot to help him with some things. I probably spend two hours there. I went home to try to get this paint off of my arms/hands and I could not remove it. I took two showers and scrubbed my arms/hands and there is still a lot of paint on there. If this is and indication of how tuff this paint is I am very pleased. I am definitly going to where gloves when applying another coat tonight.
