last minute rust bullet install questions

[TwinFins]

Planning to start the first coat in a couple hours.

Humidity today is around 55% with an afternoon temp of 85 dropping to 70 this evening.

I plan three coats of rust bullet with a heavy flake thrown into the last coat while still wet. It will be finished with 2 coats of clear.

I am guessing re-coat times will be in the 6 hour time frame. With the 1st coat going on at 1:00 PM that would put the 2nd coat around 7:00 PM and third with flake around 2:00 AM. Sound about right? I know it is dependent on conditions so if it cools off and humidity goes down re-coat times could go up.

What is the drying time before the clear goes on? Still the standard 6- 8 hours ish? What about the re-coat time for clear? Again the 6 - 8 hours?

Last, I understand the surface needs to cure for 72 hours before regular use, but if it were to rain, after say 24 hours, and the 6" apron on the other side of the garage door got wet (planning to rust bullet this as well) would this be an issue? There is rain in the extended forecast....

Thanks for any answers in advance!

First and foremost, please don't get up at 2:00 am to do your third coat

In humidity 70% or lower you have a 24 hour recoat period. The period is actually longer than that in many cases but to be safe we say 24 hours.

In all cases, including the clear, the dry time is going to vary some. Typically in 4-8 hours you can touch the floor with a gloved hand without any coating coming off on your hands. That is your indication that you are good to go.

I'm not a huge fan of coating the apron. People do it. You will find tons of posts here on the pros and cons. Mostly cons. Is there a saw cut before the apron? I absolutely would not coat any area that is going to be exposed to rain before the full coat time.

Please watch the installation video too. Some good information there on roller technique etc.

Good to know I have up to 24 hours, but with rain in the extended forecast Im actually looking to recoat as soon as possible. As long as it is dry to the touch between each coat, can I just keep recoating until finished? At a guess of 6 hours dry time per layer and allowing an hour to roll each layer out, that would total 35 hours start to finish.

I don't like the look of stopping the rust bullet at the garage door, I would much prefer to extend it the additional 6 inches past the door...there is no saw cut to use as a transition in that location. In fact, even if there had been a saw cut it would have been filled...I already filled all the saw cuts with the flex joint filler you sell. A tent of plastic over the 6 inches of apron would protect it from getting wet during the 72 hour cure time. Im confident it would be dry to the touch before rain shows up.

I understand your concerns. I just don't think this is the best idea in this case. If you could post a picture of the area or email it to me that would be great.

I coated my apron and I love the way it came out. Its been down now for about three months with NO problems, not even the leading edge.
