Temperature should be between 50 degrees F and 85 Degrees F with the air humidity below 85 percent. Avoid painting in too much wind or sun. A rapid loss of solvents will occur under these conditions and will decrease the flowing ability. Add thinner up to the specified percentage to compensate for the faster release of solvents.

I'm in Portsmouth, NH It's 78 to 89 daily.How much thinner should I use.Paint my wood Tayana 37 Mast.What thinners can I use?
Call Epifanes for a data sheet, they will email it to you. This is a new product and it is not included in their online manual. The data sheet will give you the thinning ratios and temp range. I am on my boat now so don't have the sheet with me, though I think 80deg and 85% is the upper limit. It is a great product, you will like it.
I used Epifanes Brush Thinner well mixed into the primer by 10-15% when rolling and tipping. I try to keep below 85 degrees F and 85% humidity. Let it dry for two days; the sandpaper will tell you when to put the paint on.For spray, I do the same and use Epifanes Spray Thinner and run the mix through a paper strainer before loading the gun.See Epifanes data sheets for more info. -B
what coverage rate does the epifanes multimarine primer give on fiberglass?
The side of the can says "8-10 meter squared per liter. Also says 80-100 sq ft per liter. The small can holds 750 ml and should be thinned by 10%.Stir it well; I stir for three minutes then pour and use.I use mine in an HVLP sprayer and thin to spec with Epifanes spray thinner.If you roll it on, roll it thin. I suggest so thin that bubbles form off of a 3" foam roller cover. I quickly tip with a foam brush to break the bubbles. Then, let it alone.Also, keep within Epifanes weather limits. Between 50F and 85F with humidity less than 85%. I found this to be important when using Epifanes products.Jamestown Distributors or Epifanes has a download describing all of Epifanes products.I use Epifanes products exclusively and am very happy with them.I'm building a 21ft coastal cruising catamaran and have already used Epifanes non-skid powder with their mono-urethane paint on top of the Multi Marine Primer.Works Great!-Bruce
Coverage with primer is somewhat less than Epifanes Monourethane paint so you will use a little more. It does dry fast. I can tell you I painted an anchor locker cover with Epifanes on one side and Interlux on the other. My wife used very hard, sharp fingernails in progressive scratch tests over a period of two weeks. Testing confirmed video demonstration on Jamestown website. Epifanes didn't allow scratching or marking after a few days while Interlux continued to show scratches even after drying for over a month. It is truly a hard drying product.
I used about 1/2 a quart on about 60 square feet of glassed plywood. This primer was my first foray into marine paints. Wow what an improvement over the house paint market.
Would buy again
rolls on great, sands very well . . . a little more buildup would be nice, but I think it is a very good primer. Used it on the topsides of a new wooden sailboat.
So far, so good.
Not the easiest primer to sand but by far not the hardest. Left a nice finish with 220 grit and filled the grain on my 40' wooden mast nicely. Applied 2 coats and sanded with a palm sander and paper over a sanding sponge for the corners. Haven't painted the mast yet so not aware if it will stick or not. Will update later. So far I'm a happy camper,eh.....boater.
How long do you have to paint your boat?
Primed my wooden 17' Custom Fishing Boat.Probably would be a good primer if I had all summer to wait for it to dry.
Follow the instructions
I have just finished painting the interior of a small craft, having done the exterior hull last year. Multi marine primer works great but you MUST follow the directions - even call Epifanes if you wish. They will give detailed instructions on how to prepare the surfaces prior to painting. I have had no trouble and so far it has provided an excellent one part primer for the top coats of yacht enamel. First coat was diluted with Epifanes thinner (10:1) I have put 3 coats on prior to topcoats, sanding between each. I applied using chinese bristle brush. Good product, great customer service.
One tough primer
Dilute 5 to 10% with same brand of thinner. Spray using good technique and put down multiple thin coats. Let it cure before sanding between coats. It will give you a tough, superior base for the Monourethane paint. It is not forgiving, so keep a cool head and make any "repairs" when you sand. The tech help was very instructive. I used it on a rowing shell I was building.

Great primer with good ahesion
I have used this on my side guard rails as I was tired of trying to keep varnish on them. I striped off the old varnish ,put on two coats of Epifanes multipurpose primer, and covered that with one component Epifanes enamel. That was 3 years ago and it still looks as good as the day I put it on. There are no short cuts and one must watch the temp, wind and humidity
I would not buy this again
The first time I tried this product, I brushed it on. After a week of letting it "dry", it was still soft and could be easily dented with a fingernail. I tried sandding it, and it loaded 80 grit sandpaper so badly, I had to scrape it off with a putty knife. I tried a second coat rolling it on as thinly as I could. Again, I waited a week to try to get it to dry... I was finally able to wet sand it using 220 grit sandpaper.
