3m 5200 curing problem

[pimpchevy07]

i bought a tube of regular 3m 5200 to glue my bilge pumps down. the tube says it takes a week to fully cure. i applied it 5 days ago and is just barely tack free. the temp has been about 85. i dont know if this is normal or if i got a bad tube. should i wipe it off and use the fast cure? i want to go ride! please help.

i always use regular rtv silicone... have never had one pump break free... dries in hours. wipe it up and silicone it in. just my opinion...


some will say "gas will eat away at the silicone". well i have had puddles of gas soaking around the bilge mounts for more than a week and nothing happened.

It takes a long time for 5200 to cure. For future reference they make 5200 fast cure.

you can use the 4200 for the bilge hold dopwn, or liquid nails ( Ive been using hte liquid nails most recently)

it dries in an hour or so, and is dirt cheap, like $2 per caulk tube.

Probably nothing wrong with your 5200 though, it just takes DAYS, and even longer if its humid.

the 5200 instructions say 7-14 days of curing time.

i would stick with 5200, just buy the fast cure

What is the cure time on 5200 fast cure? Is it faster than 4200? I know that you have less strength w/ the 4200, but how strong does it need to be to hold down a bilge?

i just wiped the old stuff off. i didnt even apply that much and after 5 days it was like it just came out of the tube.

go with what ever is cheap. silicone or liquid nails is cheap

5200 did not hold down my bilge(s). I let it cure for close to a month, fully sanded the spot and cleaned it with acetone. I would definetly make a bracket if at all possible!

 

[Mouthfulloflake]

Its held down several of mine.

You have to sand and clean the hull AND the plastic bilge bracket.

I have to use a chisel and hammer to remove them, and then it takes a bit of glass from the hull with it.

this is true of 5200, and liquid nails also.

go buy some of that loctite fast grab adheasive, it is a urethane based adheasive. takes about a day to dry and it works.........

 

[Mouthfulloflake]

if you want Urethane get a tube of PL-II at lowes for $3, but I cant tell a difference in it and liquid nails ( the LQnails smells worse initially I think)

silicone... easy to remove and pump doesn't break free.

I have used that and some stuff we have at work (same type of stuff). I have also used west systems with 404 adheasive filler.......
