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.

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.

After applying 5200 to my wooden boat seams, can it be sanded and painted after it cures?If it can be sanded, then how much time after application do I need to wait before I can sand it? Can I cover it with bottom paint? Can I cover it with top-side paint?
Robert
It will take about 8 days to fully cure to be sanded. You can paint it but it doesn't stick very well.

3M 5200 remains flexible and doesn't hold paint well. I'd recommend Sikaflex 291.

will this product work for gluing stainless steel hinges to fiberglass (boat storage deck compartments)
carl
It is a real strong adhesive sealant but it is recommended to use mechanical fasteners also. It takes about a week to fully cure.

I am replacing the plexiglass lens in the hatch on my bow. Need a product that will permanently adhere to the edge of the plexiglass and the aluminum frame of the hatch . Strong enough to withstand the pressure of opening and closing the hatch . Will this product work ?
Jobe
No, use either 3M 4000 or Sikaflex 295UV
JD Tech Team
can this be applied underwater?
Richard
No, the surface must be dry for it to adhere.

Permanent construction. Paintable and lasts at least 30 years! Took stuff apart that was asembled in 1986 as it is still viable.

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.

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.
