Thanks for the reminder about the extension pole!
It just so happens that I already have two pieces of 3/4 inch plywood, already cut, each 8 feet long and 2 feet wide.
I measured the interior roof bow spacing and then transposed marks with a black marker onto the top of the exterior of the roof so that I can see where the roof bows are. That aluminum skin is very thin. I do not want to step between the bows and make the skin bend concave which would cause water puddling.
I think I will first paint the entire perimeter about six inches wide with a paint brush. I have an awning bolted on the curbside roof edge and do not want to dribble paint onto it or down the sides. Then I will start applying the coating at the rear end with a 3/4 inch knap paint roller (with an extension handle!), coating from driver’s side to curb side, and work my way back towards the front to the V nose. Probably ought to buy an extra roller to use to paint the second coat. Don’t want to risk washing the first roller and not having it dry by the time I need to apply the second coat.
Which reminds me, I will need to either shorten my planks or cut a couple of more planks that are shorter. Otherwise, as I slide the long planks back as I paint, the long planks would hang too far over the front of the trailer and flip off. I think I will cut more short planks and keep my 8 footers because they will make it really easy to apply both coats at the rear end.
Today I bought 4.75 gallons of Henry 587 from Home Depot. I had to drive 50 miles each way to get to the closest store that sells the stuff. There is a chance of rain predicted for almost every day for the next 7 days here in southern Indiana.
The instructions for the Henry 587 say:
1. After washing (with TSP soap), allow roof to dry completely before application.
2. Surface may be dry or slightly damp, but not wet.
3. Do not apply if rain or temperatures below 50° f (10° c) are expected within 12 hours.
4. Apply on a sunny day when roof surface is warm to the touch.
5. If the roof surface is too hot to touch >140°, it is too hot to coat.
6. Apply second coat when the first is dry, preferably on the same day.
7. Allow to dry fully between coats.
However, the instructions do not say how long to let the first coat dry before applying the second coat. I guess I will have to watch it dry and keep touching it periodically to see how hard it gets. I do not want to put the planks on top of a gooey first coat and wreck the job.
Geez, and all this has to be done in one day. Who knows how long it will take for the weather to cooperate so that I can stick with the seven instructions; all on a time table consistent with my work schedule. Not complainin … just sayin!
Again, thanks for the help!
