Hidden fixing for ceiling panels

[bigwow]

The ceiling panels in Bigwow were varnished oak veneer that over 20yrs have gone darker. I am in the process of covering the panels with white vinyl. At the moment, they are held up with screws, into batons, covered with oak strips, also screwed, I hope to refit them with no screws showing, so was contemplating using Velcro, hook and loop.
There are eight 8 X 2 4mm panels plus the weight of the vinyl, will Velcro hold them up? will it need the whole 8ft run of velcro? or will alternate one foot pieces do? or is velcro a non starter.
Thanks in advance

I don't think traditional velcro will work, this is what I would use:

Definitely don't use Velcro. The glue isn't good enough. Us 3M Dual Lock. Use it in 2 inch long pieces, or 1 inch squares, every foot or so. If you use it in full strips it is stronger than welding. It is brilliant stuff

There are also plastic plugs and socket things you can buy, but I don't see they are better than Dual Lock if your ceiling is 6-8mm plywood

I don't have pics of them in use for a ceiling but the below shows you them use for my headboards (in the pre-cut 1 inch squares). The headboard panels are perhaps 2x the weight of ceiling panels for a given area so you would use 1/2 the density of 3M blobs if you were doing a ceiling - as I say spaced every foot or so, no more than that

The glue doesn't stick well to raw plywood surface but it is fine if you apply one primer coat of varnish or paint. To align, you attach BOTH sides of the 3M, "engaged" as it were, to the ceiling battens then peel off the backing paper to reveal the sticky glue, then offer up the plywood panel and press onto the glue, then you're done

The Dual Lock will work just fine, the entire interior panelling on the newer Princess's are all held on by 'Velcro', wall panels, roof panels the lot !

By consensus it looks like Dual Lock is the way to go then, I've just ordered a bag of 1" squares, it seems it's not two parts, just sticks to itself, that's if I've ordered the right thing.

Each square should be two parts pre-stuck together (you want it pre stuck to make installation easier, if you think about it)

The two parts are not the same - rather like velcro the textures on each side are different (though, it is not a hook and loop thing as velcro is). If I call the two different textures A and B, you'll find A sticks to B with sensible strength, and A sticks to A with high strength and some high pressure needed to make the bond, but B doesnt stick at all to B. All boatbuilding I've seen uses A stuck to B, and AFAIK the squares come as A stuck to B

Reading your post, I'm wondering if you have just got a load of squares of A which will stick to itself (a bit to strongly tbh - you'll want to use a screwdiver to prise them apart once they're stuck to rigid wood). Not a disaster anyway.

You're right! I bought the wrong Dual Lock, there is quite a range.

3M tells me the Dual Lock for this job is SJ3560

I just thought I'd mention it in case anyone else is doing a similar job.
