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.

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 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!
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
could I use the 3m 5200 on the keel guard to a fiberglass boat
Depends on the types of material being bonded.
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.

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!
I would not use 5200 for wood to wood. Rather, I would use a waterproof woodworking glue such as Titebond 3Terry Ney
I'd head towards epoxy.
Titebond III would be my first choice providing the surfaces are clean. Never have used 5200 for laminations.
I would not use 5200 to glue a dugfir bowsprit together. Epoxy glues work well
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.

Went on smooth gust make sure you uses all of it the first time the leftover we'll harden .
Great Price and Quick ship!
Wow, happy with the product! Restoring a bottom on a 57 Chris Craft. Restorer assisting me wanted $70.00 more a case than originally quoted siting a price rise from his source. Jumped online and found Jamestown had the best price! Thanks!!
The Very Best
3M 5200 is the best since Bearcat body deadener from 1949. Sticks to anything, is strong, cures without shrinkage, & it's DURABLE. Thank you 3M. Don't like to thank mega corporations, but this stuff is fantastic! Nuff said.

New bottom on 22 Hackercraft
great item and fair price
We use this at a telecommunications company to hold plastic corners on large batteries that have cracked and are leaking electrolyte (700 lb batteries with 25 gallons of acid in them.) When properly installed the acid will not leak through the adhesive!! Good stuff for sure
