    Posted: 02 Oct 2011 at 1:15am
I have removed the badly deteriorated gelcoat from my decades-old 15' Cape Cod Mercury sailboat. I completely sanded to bare fiberglass. I have done some fairing work with compound made of epoxy and filler. I plan to do a barrier coat of 3 coats of epoxy. After much research, and much frustration at the lack of products appropriate for the bottom of a small, trailered sailboat, I finally found VC Performance Epoxy which seems to be exactly appropriate for my needs. I plan to paint the entire hull with this including the topsides. My question is this:

How much will I need? I haven't been able to determine the exact sq. area of the Cape Cod Mercury hull. A very sloppy calculation of the 15' length by a guess as to the average width dimension of 6' gives me 90 sq. feet. I've seen coverage figures for this paint of 200 sq. ft./gal on the Jamestown Distributor's website and I believe 120 sq. feet on your site. Is this for all three recommended coats or for one coat? If I buy a gallon and have some left over, can I use it on the interior of my cockpit? How about on the deck? (which is mostly non-skid) If not, which of your products would be best?

Also, is a cartridge respirator adequate if I am going to be spraying outside? Do I need to have shade to spray? I am in Fort Myers, FL and the weather is finally starting to cool and dry a bit here. Probably will be in upper 70's to mid 80's F by the time I'm ready to spray.

Hi Dan,
The VC Perfomance Epoxy would certainly be a suitable paint for you to apply to the bottom of your sailboat. However I would recommend that you avoid the application of this product anywhere above the true waterline (hull, topsides, deck, cockpit), the reasoning behind this would be that the VC Performance Epoxy has no UV filters/protection therefore if it is applied to surfaces which are exposed to the sun the coating may yellow and begin to chalk out. With that being said, I would recommend that you apply the VC Performance Epoxy from the waterline and below only. Based off the dimensions in which you have provided I would estimate that you have 77 sq ft of a surface to be covered (15 x 6 x 0.85 = 76.5/77). The actual coverage for VC Performance Epoxy would be 200 sq ft per gallon. Therefore you will require 1.5 quarts per coat and a total of 4.5 quarts for 3 coats. The product will remain good in the can as long as it had not been mixed with the curing agent and each can had been completely sealed.
With regards to respirators which are suitable for spraying this would be a question which would be best awnsered by the respirator manufactuer such as 3M as they would be able to tell you what their catridges can handle. When calling 3M they will ask for a bit of information with regards to the coating specifically, this information can be found on our MSDS's. The following links will bring you to the MSDS for each component of the VC Performance Epoxy:
When applying the VC Performance Epoxy whether it is by spray/roller/brush it is always best to work in shaded environements.
As for surfaces above the true waterline I would recommend that you apply a topside finish such as Perfection or Brightside.
Hope this helps!
