Fiberglass Bottomkote® NT uses a dual resin technology that provides a universal durable, fast dry antifouling paint that delivers the benefits of both hard and ablative antifouling paints for use on all power and sail boats. The universal formula of Fiberglass Bottomkote® NT has durability of a traditional hard paint but has a slow polishing mechanism built-in that continuously smoothes and renews the active surface avoiding the heavy build-up of paint layers much like an ablative paint. The fast dry formula allows the boat to be painted and launched in the same day. Fiberglass Bottomkote® NT provides clean stable colors for effective season-long protection. Fiberglass Bottomkote® NT is recommended for use on the underwater areas of fiberglass, wood, and properly primed metal (except aluminum) boat hulls. It can be used in fresh, salt and brackish waters.

|How Much AntiFouling Paint Do I Need? |
|Determining how much antifouling you will need is fairly simple. You can calculate the area to paint by multiplying the length of your hull (LOA) by the beam and multiply by 0.85 (LOA x B x 0.85 = Area). Then divide the area by the coverage of the paint you've chosen to determine how many quarts per coat you will need. |
|Refer to the reference chart below for another quick estimate of how much antifouling paint is required for two coats. |

Video Transcript Matt: Hi, I’m Matt Anzaro with Interlux Shop Finishes and we’re here today at Brewers Sakonnet Marina here in Portsmouth, Rhode Island, and today, we’re going to be conducting the Fiberglass Bottomkote NT challenge. Before we talk about the challenge, let’s talk about the new product. Fiberglass Bottomkote New Technology or NT, utilizes the latest in anti-fouling technology.
By formulating a product using two premier resins our dual resin technology, we’re able to provide the benefits of a traditional hard paint along with the added benefits of an ablative paint.
So what are these benefits? The benefits are slow polishing rate for optimal performance. It also has a durable, smooth surface optimizing speed. Super fast resin which allows you to paint and launch the same day. A smart copper release system with all the performance without the excess copper, and it has a reduction in paint build-up over time. Fiberglass Bottomkote NT offers all these benefits and comes in multiple colors and sizes all at a great price.
What is the Fiberglass Bottomkote NT challenge? Well it’s a way to show how during application, that the Fiberglass Bottomkote NT will actually go further than the leading competitor product, which we’ll be calling Product X.
Now I’m joined by Dave Rodericks, and he’s the yard manager here at Brewers Sakonnet, and he and his crew are going to help us paint this boat with doing the NT challenge. And so Dave, can you tell us a little bit about the boat?
Dave: What we have is a Wellcraft V-20 step lift. It’s 20 feet long, typically it should use probably two or three quarts of paint, but we’ll see what happens.
Speaker 1: Twenty-Four?
Matt: Twenty-four. So what we’re doing with the NT challenge is we’re going to split the boat down the centerline, and on the port-side we’re going to be painting the Fiberglass Bottomkote NT, and on the starboard side, we’re going to be painting on the Product X. See which one goes further. We’re going to be using the same rollers. A three-eighths snap roller for both applications.
What I’m doing now is checking the film build on this, and we’re getting about five to six mils wet which is where we want it recommended. Generally we recommend about four or so. You can go a little lighter if you wanted to.
New Technology. He’s putting on four mils wet still, still putting on at four mils.
Speaker 1: Really?
Speaker 1: Huh. Might want to try this.
Matt: Okay. Let me try this still four mils because I think all we need is one more ounce to be honest.
Speaker 1: I’m probably going to finish it all.
Matt: Alright. What we got now is we painted the port-side with the Fiberglass Bottomkote NT and it took 25 ounces to paint the boat. So now we’re going to use Product X and paint the starboard side.
This is Brand X and what we’re going to do is we’re going to mix it up. We’re going to pour out 25 ounces and we’re going to be painting the starboard side with this and see how far this goes.
Speaker 1: This one’s really thick.
Matt: What he started out with NT is already dry to the touch. It’s about a half hour since we painted this section. We’re using the same rollers – a three-eighth snap roller for both applications. We’re going to check the film build on this as well, and what we’re seeing is four mils wet.
Dave is still putting it on at about four to five mils which is again per manufacturer recommendations, but he’s all out of paint at this point in time. So what we have here is that the Fiberglass Bottomkote 25 ounces painted the entire side where the Product X left about a third of the boat unpainted.
What we’ve done is we obviously have more boat to paint so we have to get some more paint. We’re going to add another seven ounces and that will be a total of 32 ounces for this side. First is 25 on the Fiberglass Bottomkote NT.
We’ve added another seven ounces to the tray here to finish up painting the starboard side with Product X, so it’s a total of 32 ounces that we’re going to be using for the starboard side with Product X and 25 ounces for the Fiberglass Bottomkote NT.
So Dave, what does this mean for you?
Dave: Well from an applicator’s point of view, it’s going to be savings, obviously, material-wise for customers. The fact that we can launch the boat the same day we paint it is also a substantial goal for us as far as saving time and getting our customer’s boats in the water.
Matt: So what we found now with the Fiberglass Bottomkote NT challenge is that the Fiberglass Bottomkote NT took 25 ounces to paint the portside of this 20 foot Wellcraft. And Product X, it took 32 ounces still wet as well. The Fiberglass Bottomkote NT gives you 20% more product in that can than Product X. So it gives you better performance, it goes further, and you’re able to paint and launch in the same day. More time to go boating. All at a great price.
I’d like to say thanks to Dave and his guys here at Sakonnet Marina and if you’d like more information about Fiberglass Bottomkote NT, or other Interlux products, please go to our website at yachtpaint.com, and remember, your bottom leads the way, so make sure it’s Interlock on your boat.
Thank you and have a great day! read less
