3M 5200 is a single part sealant that cures to form a firm, rubbery waterproof seal. When fully cured, this high strength marine adhesive remains flexible and suitable for use where shock, vibration, shrinking or swelling are concerns.
Use 5200 on wood, fiberglass, hardware, motors, on fiberglass transoms, seams, joints, between struts, and planking stern joints. This permanent adhesive bonds and seals: fiberglass deck to hull, wood to fiberglass, portholes and deck fittings, motors on fiberglass transoms, under moldings, hull seams above and below water line, centerboard trunk joints, between struts and planking, stern joints and more.
Apply with a manual caulking gun. Sealant remains workable with a trowel or spatula for up to four hours, and won't sag or flow in vertical or horizontal seams.

This high performance polyurethane adhesive sealant becomes tack-free in 24-48 hours, and completely cures in 5-7 days with no shrinking. The seal is extremely strong, retaining its strength above or below the waterline. 5200 stays flexible and allows for structural movement.
Consider using 5200 Fast Cure instead if the quickest possible cure rate is a consideration. It has slightly less tensile strength, but provides full cure in as little as 24 hours.

Can 3M 5200 be used in a hot tub to seal around the jets? Will it be ok in 104 degree water that is chlorinated?
I can't even guess on that one. Have only used it on boats and it is outstanding, but then I avoid sailing in really hot water.
what type caulking gun is used for 3m 5200 sealant
No gun needed for the small tubes I bought
I have to cut a Proline center console fiberglass decking to replace the leaking fuel tank. If I have a clean cut, can I use the white 5200 to reseal the decks back together? Of course with the proper support for the section that was cut and removed.
Not the best. The seam should be ground down to a bevel and laminated with fiberglass tape and epoxy resin.

Will this work to repair rubber boots? Muck Boots?
It may, use a piece of inner tube, rough up the area and the patch. Use the fast cure. Be sure there is full contact for it to set up.

I have used 3m 5200 on my sailboat and it is multipurpose. I want to use black on my gutters but when I try to order it, the number comes up as 06504. Is this the same product?Thank you
Yes the MMM-06504 is 3M 5200 in black a 10 oz tube.

What color will it dry to?
It comes out white and dries to white. It also stays pliable when it dries.
Will it adhere to concrete and block?
I realy don't know i only used on my boat
Yes it will as long as it is clean and dry to begin with
I never used it on concrete but have caulked deer blinds, fishing wells in my old boat!I don't think you would have problem with adherence to concreteIt's water proof and better than other caulking!Doesn't shrink but it takes a good 24hrs to cure!Hope that helps!
could I use the 3m 5200 on the keel guard to a fiberglass boat
This would depend what material that the keel guard is. Please feel free to reach out to one of our techs at (800) 497-0010 so we can help you find the best product for this application.

Depends on the types of material being bonded.
Will 5200 seal a shower joint and last better than caulking?
It should but I don't know. For sure. We used it to attach sheet metal to side of house. Bond is still good.
5200 will be a much stronger bond, but if silicone was used in that spot in the past the 5200 may not be able to bond properly. If the substrate will not let it bond, it will not perform any better.

Any reason not to use 3m 5200 to laminate a delaminated bowsprit back together? I'm sure it was originally glued with resorcinol. It lasted for 32 years and was still stuck pretty good but I managed to get it apart without damage. The bowsprit belongs to a 1986 Pacific Seacraft and is made of Douglas Fir. Appreciate any and all recommendations. Thanks!
5200 may not be the material for fixing the delimitation. We commonly recommend epoxies, or thickened epoxies to bond with the wood and add strength.

Titebond III would be my first choice providing the surfaces are clean. Never have used 5200 for laminations.
I'd head towards epoxy.
I would not use 5200 to glue a dugfir bowsprit together. Epoxy glues work well
I would not use 5200 for wood to wood. Rather, I would use a waterproof woodworking glue such as Titebond 3Terry Ney
I have been using this product for years.
I use it on my wooden boat to hold hardware and some of the planks ,because its flexible. Also use it on my inground swimming pool tiles.
I would buy this product again
Used this to glue a rib system on a paddleboard. Works awesome
Slow to cure and difficult to clean up but PERMANENT.
I would buy this product again from Jamestown.
Chalking adhered great to fiberglass and concrete.
Permanent construction. Paintable and lasts at least 30 years! Took stuff apart that was asembled in 1986 as it is still viable.
Two Rivers, wi.
Used for bedding.
Excelent service from the person who filled my order.I would have liked a spare nozzle with the tube, as I don't use a complete tube at once. Theremaining adhesive in the nozzle hardens and I have to dispose the remaining adhesive.

I bought this to seal the seams on a v-bottom aluminum boat that was leaking water into the boat. I used a brass wire wheel to clean the seam, and applied the material, waited a week, and no more leaks. Some people said that it was hard to apply, however I didn't think it was any different than caulking you would use at home to seal your house.
