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.

could I use the 3m 5200 on the keel guard to a fiberglass boat
lucas
Depends on the types of material being bonded.
hcfirstlight
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?
Scooter
It should but I don't know. For sure. We used it to attach sheet metal to side of house. Bond is still good.
mnkaplan
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 use 5200 for everything. Using for your repair would certainly be successful. Use a complete coat, not too thick and clamp tight for at least three days. It should last another 30 years.Donald A. Davis139 Tom Franklin RoadJefferson City, TN 37760Sent: Monday, June 18, 9:05 PM

I would not use 5200 for wood to wood. Rather, I would use a waterproof woodworking glue such as Titebond 3Terry Ney
tney88
I'd head towards epoxy.
jim_goese
Titebond III would be my first choice providing the surfaces are clean. Never have used 5200 for laminations.
danengelke1
I would not use 5200 to glue a dugfir bowsprit together. Epoxy glues work well
shearwater3
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.

Can I use this as a substitute for Dolphinite?If not, does Dolphinite come in smaller quantities? Don't need a lot and don't want to waste a bunch Thx
Robert
I have used 5200 to bed deck hardware and below the water line transducersand thru-hulls.It is very tenacious once cured, there are 2 types normal cure and fast.Fast is great for one day turn around.
timbgallaugher
Pints are unfortunately the smallest size we have for Dolphinite. If you are just rebedding deck hardware, you may want something like 4000uv that is not as permanent as 5200.

i used 5200 to install the screws in a transom mount transducer the launched the boat about 6 hours later the 5200 was old, it was pliable when i used it and it was firm when i launched the boat do you think it would be dry enough or did i screw up
fair catch
If the boat is going to stay in the water all the time, I would pull it and check to be sure it sealed properly. 6 hours is too soon even for the fast cure.

will your 5200 sealant work on abs black water tanks
riptide
It will work as a sealant, not as good for an adhesive.

Will this product work for patching a mesh inground pool cover? I'm planning on adhering a new piece of mesh pool covering over the torn section using this product. Anyone ever try it?
joon
It will probably work, use the fast cure version, the regular 5200 takes a week to cure.

I have an old truck radiator (100+ years old) with a "honeycomb" cartridge core. The issue is that the bottom of it split internally under the cores when someone left water inside of it during a frost. I was thinking of using the tube type application to squeeze the product into a few of the core honeycomb openings that run though to the other side to seal the sections that split. My question is what is the viscosity? For instance, could you theoretically squeeze this product through an opening the size of a straw? Also, what temperature would this be protected up to? I recon the radiator temperature gets up to about 200 degrees F. This vehicle is used very seldom and usually operating times are twice a weekend for about an hour. Thanks
Sean
If the product is warm, the viscosity will be easier to extrude through a fine tube but still a bit hard to do. Second, when it gets hot (200) degrees even when cured it will soften up a bit and may not hold up if under pressure.

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.

3M5200 IS THE BEST
5
BEEN USING 3M5200 FOR A LONG TIME. IT'S STRENGTH AFTER CURING IS AMAZING. SOMEWHAT DIFFICULT TO APPLY IN SOME SITUATIONS, BUT THAT IS OVERSHADOWED BY ITS EFFECTIVENESS. I USED IT ONCE TO SECURE A DOOR SILL TO CONCRETE IN A VERY HIGH TRAFFIC AREA: ITS STILL THERE AFTER 10 YEARS AND HASN'T BROKEN FREE. ENOUGH SAID.
