Video of the Week: Boat Painting 101 – Spraying Topcoat

After a very thorough prep and priming job on the BlackWatch 26, (see the prep video here, and priming video here) it’s finally time to apply the 2-part polyurethane Quantum 99 Topcoat. This paint is a high-solid topcoat which was chosen for its durability and ease of repair. Most imperfections in a Quantum99 paint job (from the paint job itself or from light damage to the hull and paint job) can be easily buffed and polished out of this superior 2-part paint.   Brendan will be spraying the paint, onto the hull, a fairly new process for him, and as such Jon Boswell of EMC paints is on hand to give him some tips and show him how it’s done.

Keep in mind, this is a pro doing his first spray job. We understand you might not have a spray booth set up in the garage – or have a compressor and spray guns at the ready, but this paint is easily rolled and tipped and levels itself nicely. We thought showing you how he was taught would be a great way to decide how you want to paint your own boat. And this was using a 3M spray gun bought at an automotive store. Nothing too fancy! Best of all is Quantum99’s repairability once hardened. And we will get to that in the next video! Thanks for watching!

  1. unfortunately I’d give this video a “D” as compared to the other videos in this series. The lack of commentary and overall directions were the cause of this grade. I thought the purpose of these videos was demonstrat the procedures while also promoting your products. Sorry, It did neither.

    Please try again, but use the format from the first video and you will have accomplished something worthwhile!

    • Sorry to disappoint. We will always be trying again and some videos will please some people and leave others wanting more. Hull prep and spray painting a hull are also pretty different and we don’t intend for the tougher jobs on video to be a step by step – but more of a guide to show you the process. Keep watching and we’ll keep trying to make videos you like and want to see!

    • Here is the official reply from EMC: “Being a true high solids we had HVLP in mind to further increase transfer efficiency and lower emissions. But we also kept in mind the other conventional methods of spray application to not narrow ourselves into one category” – Brad Martin President of Technical Operations

      The paint has a specific SPRAY REDUCER that must be used when spraying to make it “specifically” for spraying. Hope this answer helps. thanks

        • absolutely! we have several boats here on site as a testament – and EMC has many many more. The BlackWatch had one run that will be buffed out in the next video (coming Friday) but had zero fisheyes or orange peel. The paint really leveled itself out nicely.

          • Thanks for your response. I’ve had issues with that with other products.

  2. I like to echo above reply by P. Maundrell. Also, unless Quantum 99 Topcoat has some new wave chemistry, I would be VERY wary of spraying polyurethanes without using a forced air respirator.

    • Quantum99 has double the solids, half the VOCs, and no free isosyanates as compared to other traditional high solid marine paints

      • Kristin, thanks for reply. Recommend adding your info to the video. I can not comment about proper usage of Quantum 99 regards short/long term exposure, except to say based upon a career in semiconductor industry as a process development engineer, proper isolation of workers from chemical exposure was necessary first step.
