More PMF Advice

PMF Advice - This is the rear of my trailer. My plan to cover it was to cover the lower horizontal piece first, wrapping it over & around the back of the wood. Next would be the 2 vertical pieces. My canvas is wide enough to wrap 1" onto the sidewalls and in& around the back of the opening. Finally the top piece with a 1" overlap onto the roof and in & around the opening.

My sidewall pieces are long enough to wrap over the front wall and completely wrap the rear corners and are wide enough to overlap the roof. The roof piece is long enough to wrap the top of the rear opening, cover the roof, the slope and the front wall and is wide enough to overlap the side walls. Thoughts? Thanks

In general, overlap should be handled like you would if it were shingles. That is, water will flow over a seam even if the bond at the overlap wasn't perfect. So sides on first, then the top overlapping the sides.

Sometimes, for aesthetic reasons or just the nature of the area you need to cover, you end up with a vertical seam or worse, a seam overlapped in the wrong direction. In that case, take extra care to ensure the seam is perfectly glued and coated with several extra coats of paint and inspect that seam frequently.

Your fabric layup sequence is good. Same thing with fabric sizes.

How are you going to attach and then saturate the cloth?
Paint? Glue?

I attached with undiluted TB2 glue. Rolled onto the wood. Applied cloth.
Then used a 50/50 mixture of TB2 glue and water to saturate it all.
Sanded it when dry. Applied 2nd coat. Sanded again. Painted it.

Could not have been happier with the results. Hope the same for you OP.

I started on the rear opening. Bottom horizontal first. Then the upper horizontal - it overlaps the roof 1". The verticals were last. They overlap the side walls & bottom edge of the 3/4" ply side walls, but not the roof. All pieces are wrapped & glued around the framing of the opening. Sides and back of all the pieces.

Thank you. I'm using undiluted TBII. I changed the application order a bit. Bottom horizontal, top horizontal then the verticals. Top horizontal overlaps the roof 1" as do the verticals on the side walls.
