Using Aluminum Composite Panels

[aggie79]

[quote="Andrew HerrickDo you know how thick the alunimum facing is? I'm curious about the product, too, but I'm wondering how it will hold up years down the line ... can it be acid washed seasonally? [/quote]

I guess I'm curious as to why anyone would want to acid wash aluminum annually? Maybe it is a corrosion issue from road salts or something.

The aluminum sheeting on my teardrop is anodized. I do apply a coat of carnuba wax annually to help wash off tree sap and bird droppings but that is about all the maintenance I do.

I bonded my first piece if ACM to the camper last night. Just a small piece for the rear bumper area. Glued it to plywood with Loctite PL Premium. The 3x version, not the 8x Fastgrab. Played with the 8x a little and didn't like it. The 3x is much easier to work with. Sanded the back of the ACM before applying the adhesive, and clamped it in place. I don't think I could tear it apart without destroying something. I think this is what I'm going to use for the rest of the project.

Looks great! I'll be following your ACM experiences and your build closely. Thank you for posting this.

Things are moving along, and the ACM is working great.



Cut the basic wall out of 3/4 plywood



Roughed up the backside of the ACM with some 150 grit sandpaper to help the adhesive have something to grab onto



Loctite Premium PL adhesive



Laid the glued up wall down on the ACM, walked all over the backside to spread out the adhesive, and "clamped" with a bunch of cinder blocks

Let dry for 24 hours



After it dried, flipped the wall over onto the worktable to trim the edges. Moved it outside because cutting ACM can get messy.



Flush trim bit on the router



Router cuts extremely well thru the ACM. Thought I might need to pretrim closer to the final shape, but no need.



And there is the final wall mounted to the floor.
