Works underwater! Slick Seam is a remarkable underwater caulking compound made of fine waxes, pure mineral products, and silicate fibers. Slick Seam is an excellent underwater seam compound for wooden boats. Requires no mixing, stirring or priming. Made of wax, pure mineral products and silicate fibers, Slick Seam adheres well to most solid surfaces whether dry, wet or even oil stained. Applies easily and cleans up fast with mineral spirits. Cures ready for paint in 30 minutes. Stands up well to flexing and swelling wood. One jar is enough to caulk the seams on most boats to 20'.
Slick Seam comes in a 16 ounce jar.

Why do you say boat must go back into water immediately? Product literature says "Slick Seam adheres well to most solid surfaces whether dry, wet or even oil stained. Applies easily and cleans up fast with mineral spirits. Cures ready for paint in 30 minutes. Stands up well to flexing and swelling wood." I would think many to most boats where one would use this product spend 8 or 9 months out of the water each year.
That is incorrect, we will get it fixed on the web site. Thanks

Re-caulking the bottom seams of a 1965 mariner 40 wood hull. How well does this product compare to the Interlux seam compound and what are the differences ?
First and foremost, Slick Seam is for the most part, wax with some mineral spirits and some filler. It stays soft and does not take pain w/o discoloring it. After you have applied cotton or oakum caulk, using a paint knife work Slick Seam into the joint. While soaking the slick seam will be pushed up into the caulking by water pressure. As the blanks expand the compound is pushed out of the seam. This behavior decreases swell time and creates very little chance of a popped blank. It is also very "undoable", it is relatively easily removed. I have used it on my 1961 36 ft Egg Harbor convertible sedan. While I need to reapply every 2 seasons, the behavior and the lower risk to the blanks makes up for it.
I've never used the Interlux product. Slick Seam is basically a wax. If used in all the seams, it makes the hull relatively watertight as soon as the boat goes in the water. As the wood planks swell, the compound is soft enough to displace without putting stress on the plank fastenings. If the planks open up a lot during winter storage on land, you will probably have to renew the Slick Seam every year. Hope that helps.

As a long time wooden boat owner and restorer I have used this product religiously. Primarily as a caulking for open seams at the first launch of the season and for leaks that open up during long hard sailing or rough running. I would recomend it as my primary tool for these purposes. The label says you can use it as a caulk and and paint over it but I have not found that to work well for me. If you are redoing the whole bottom. A well payed seam and standard removable caulk is your better bet. Unless it's a last ditch effort to get a few more seasons before the burn barrel. Remember only below the waterline as it is wax and it will melt an run in the heat.
I have a lapstrake, white cedar on oak frame sailboat.I would like to have more details about the application of this product. also what color is it?
light green in color, it won't help your lapstrake. It is almost a bee's wax which is good in carvel plank seams, which swell and excrete the caulking
The color is dark green. It is incredibly easy to apply. We applied it below the water line at seams. Will haul out in a week; seems like it worked well, tho. Was applied over a water based bottom paint, so we will see...
is it possible to use this product below the water line when the boat is in the water to stop minor leaks - ie by applying it on the inside of the seams?
Yes, You can
Easy to apply and stays flexible
Have used on a wood lobster boat for 12 years. It sticks well wet or dry and stays flexible so you can push it back in or trim each year. Have used during short lifts to stop bigger leaks. Paint sticks to it pretty well and have used it a bit on topsides under semi-gloss white. Have also tried name-brand caulks but they harden, crack and fall out.
Only one I use
Preparing my 36' wooden sloop for launch every spring requires me to fill the seems with a bit of something and the products listed to do this are many. Of all that I have used in the past five years, I have found Sllick Seam to be the easiest and the best. I recommend that the application be done in temperatures above 60* because the stuff is much more manageable when soft (it stiffens up when cold). The key is it does the job in the water till she swells and doesn't seem to mess with the bottom paint.
This Product is Really Slick
I used Slick Seam to seal the seams on my Venetian gondola. It was easy to apply and sealed the few seapy spots perfectly!
