Product Details

Interlux Seam Compound is available in two versions: one for above the waterline (white), and one for below waterline (brown) applications. Both boat seam sealers exhibit excellent adhesive qualities when applied over properly primed surfaces. Easy to apply either formula using a putty knife or spatula.

Seam Compound Brown 30 is specifically designed to the fill seams of wooden boat bottoms and to fill keel joints that flex. Brown 30 is a tried and proven performer that remains durable and flexible after immersion to absorb expansion and contraction of planks. Not for use above the waterline or on aluminum outdrives.

Seam Compound White 31 is a tight sealing material used to fill wooden boat hull seams above the waterline. The seam sealer remains pliable to allow plank contraction and expansion. Not for use below the waterline or on aluminum outdrives.

Sand bottom before applying to seams. Apply with two opposing knife strokes. Finish seam with rag soaked in paint thinner as you apply. Drying time is up to two days.

The viscosity varies greatly from can to can. Some is way too hard to force into the seam and some had a hardened layer on top that had to be removed. Perhaps a product this specific to wooden boats ist on the shelf for a long time.

Interlux Seam Compound

7 years ago

When I opened the can and tried to scoop out some of the compound with my putty knife. I discovered that the compound was quite dry and hard. I read on the can that you are not to dilute the compound,but I had to in order to get it pliable enough to put into the boat seams. I would have returned it to you however I was in a hurry to get the boat ready for bottom paint I decided to thin it enough to make it pliable to press into the boat seams., I think It was part of old stock. Just thought you might like to know

My order when placed said I could order this with free shipping if I spent $99 or more. I placed the order. When it shipped the full shipping was applied to everything ordered. I then read their policy fully and fund this item does not qualify because it is Haz Mat. I wish that had shown at the time I placed the order. I wound up spending $40 more than I thought it would cost. Not very happy with JD.

Q: Can brown #30 under water seam compound be placed directly over cotton wicking/caulking?

A: Best practice is to prime it first with your waterproof primer or bottom paint of choice.

Q: Will this apply over seams first hit with cpes? Does the cpes take the place of oil primer, or should I use both?

3 years ago

1 Answer

A: After applying several coats of CPES, I applied two coats of an Interlux wood primer for marine applications. This white coat was applied with a foam roller on the flat surface and hand brushed into the seams. After drying I used painters tape to mask off the seams. I then applied the Interlux Seam Compound with a narrow putty knife. I then applied two coats of a copper based anti-fouling paint for the final coverage. Scott Valentine

Q: I have an above water seam. Wood is painted. I have corked with cotton. Directions say to stuff wide seams with cotton. Next sentence says paint. Seems weird to paint the cotton. Shouldn't the seam compound be worked into the cotton?

4 years ago

A: Seemed odd to me also, but the cotton will draw the solvents out of the seam compound and make it brittle and it will crack.

Q: We have a 80 year old wood boat with cedar planks and varying gaps between planks. We completely raked the seams 3 years ago and installed new cotton. Then used the below water line interlux seam compound (brown). The can we had was quite hard and difficult to install. After it cured in the seams for several weeks we applied pettit copper bronze anti foul paint to bottom. Unfortunately this year the below water line seam compound is hard, brittle, and falling out in spots. Is there any reason that the anti foul paint caused the seam compound to dry out? Anyone else with a similar experience? Suggestions for moving forward?

A: To update my previous reply. I now water tested the boat after applying the boat life caulk. That product worked wonderfully and was way easier to apply than the interlux product. I also was impressed with the service speed by Jamestown as always. I also used the interlux compound during this past winter on the below water bottom wood of my 1963 Chris Craft. I raked the seams and installed new cotton also. My can was also very hard which made it difficult to work with. I just figured that was the way it was. Results turned out to be disappointing. When launched this spring I had many leaks and took on water at an uncomfortable rate. After less than 10 minutes I retrieved the boat onto the trailer and brought it home. On examination, I see the interlux product is very brittle and seems to have shrunk and is coming off. I did not apply paint over it as I had suspicions as to how well it was going to do and wanted to do that initial water test. I purchased Boat Life Life Caulk which is a below water caulk and have applied that everywhere I see the need. Will do another launch test late this coming week. I just want the boat to be serviceable for the summer family lake visitors and do a complete rework on the boat during winter 2020 when I decide what product to use. The Caulk product was wonderful to work with by the way and the service from Jamestown was excellent as always.

Q: Hi I have a wooden john d little catboat. I've stripped the varnish off the hatch and now need to fill in the seams between boards (top is made up of 3 boards). What should I use for that? and do I caulk before or after varnishing? thanks for your help.l

4 years ago

5 Answers

A: I would varnish first. I had a problem with the seam compound as it never set up. Even months after putting it on it still smeared. I don't know if I did something wrong or what but it never set. I ended up digging it out and put 5200 caulk in its place and it looks and works great. Dave

Q: Can I use interlux brown seam compound above the waterline to fill seams on a hatch which will then be varnished? I only need a small amount for the hatch (filling 2 - 24"" seams) and I will use the remainder of the can for the bottom. Hoping I could use brown for both. Thanks for your help.

A: I would not use the seam compound for this purpose. I would use a caulking compound like Life Caulk, Sikaflex or 3M. These come in a teak color. ?

Q: I have a 1936 mahogany planked boat that has been out of the water, my guess is at least 1 1/2 years. It was partially glassed and I removed the glassing. I am in the process of caulking the seams with cotton and compound. The seams below the water line were splined and I have begun to remove them. Upon removing the splines I discovered the planks are battoned inside the hull. The seams have a 3/8"" gap. My question is will the battons allow the wood to seal the gap when she is returned to the water. Thanks!

Q: what type of primer should I use on the seams prior to applying the interlux seam compound brown?

6 years ago

4 Answers

A: If you are applying the seam compound over caulked seams, no additional primer is needed. However the compound is much easier to apply if it is heated first. This makes it more liquid and eliminates the crumbly texture. You might find it helpful to add some thinner as well.
