How long do I need to let the sealant dry?

[gkosel]

I am going to be installing my new Smart Tabs (SX) this weekend. I plan on using the 3M 4200 that many on the board have recommended.

However, I have not read anything about how long you need to let the sealant dry/cure before you can put the boat in the water.

Also, is it best to put sealant on the screws and in the pilot holes?

Thanks,

It's tack-free in 1-2 hours and completely cured in 24-48 hours.

Use it on the screws, in the holes, and on the hardware. With a damp cloth ant excess can be removed before it tacks up.

Thanks of the info Reel Poor.

So, how long do I have to wait before putting the boat in the water?

Is it OK to put it in after a couple of hours? Or should I wait the 24-48?

The boat is at the lake 75 minutes away and I won't be able to get there until Friday, but would like to use the boat this weekend.

Thanks for any extra info you can provide.​

The 4200 Fast Cure will cure thru 6mm in 24 hours at around 70 degrees. If your wanting to use the boat for the weekend I would do the install Friday evening and go boating the nex day. With the thin application you are doing I would allow 6-8 hours.
