Hi! Did you know it´s really easy to mold corrugated steel roofs, as well as tiled roofs using PVA-glue.

Amazing!

Pretty neat technique!  And so simple, too!

I wonder if, since it sort of looks clear before painting, it could be used for a greenhouse covering....

Thanks for posting, Martin!

Wow

Martin, you never cease to amaze with your simple, inexpensive techniques.  I wished I watched this a few days ago...

Ok something is not looking

Ok something is not looking right here.

in the video he is basically casting a one sided piece or an open face mold and it is a really interesting technique.  The open face results in one side being corrugated   and the other side being flat.  But in the photo at the beginning the corroborated metal is corigated on both sides,

Hi! Thank you for all the

Hi!

Thank you for all the positive feedback! This way of copying shapes using PVA-B glue has been around for a while, so I don´t want to take the inventors cred here... My mission is to spread knowledge..

Okay Doug.. Yeah.. It depends on how you will use the roof. If you glue it towards a balsa sheet, or plywood then you can make the layer of PVA-glue really thick. The roof will be more ridgid and easy to handle. In the case with the thin corrugated sheets at my finger tip I just painted on a tiny layer of glue and let it dry.. Then painted with Humbrol silver/metal colour. This will get hard over time, but still a bit fragile..

There was another comment here on the paint. Yes, it´s a solution based Humbrol paint "metal". (Water based is a bad idea..)

Hi Al,

No, not clear enough.. I would go for something like WS watereffect to get that really clear surface suitable for windows. However, I use plastic packing from toys and food and stuff for that purpose..

Personally I don't need double sided I am thinking it could be useful for coal tipples.  Make a core from plastic then glue this on.

 

I wonder if you could use one of the yellow water resistant glues

Thanks for sharing!

Martin, thanks for the video.  I am assisting on a project of building a warehouse in HO.  Actually we are doing only 1/4 of the warehouse as the complete building would be 9 feet long and over a foot wide.  Even 1/4 of the warehouse has a lot of roof to cover! This might be the perfect solution: good looking, inexpensive, and quick enough to allow us to complete the roof in our lifetime...

I think this would be fine to represent the 'clear' fiberglass often used for green houses, as that stuff is really not clear but, rather, translucent.

Everyone is entitled to an opinion. It's rather a shame that not everyone keeps it to themselves. That's my opinion.

Very clever, Martin!

Gets a big  from me!

I'm thinking that perhaps giving the "glue casting" a coat or two of a matte spray sealant, such as Dullcote, would enable me to safely apply a follow-up color coat of water-based acrylics. What do you think?

     I doubt there would be a problem spraying acrylic over the dried glue since thin coat of acrylic would dry in a couple of minutes ,especially if you hit it with a heat gun. A coat of spray sealer might a add unwanted thickness to the corrugated material. I guess a shot of spray bomb sealer could be tried on a test piece if the acrylic directly over the dried glue method didn't work......DaveB
