Realistic Corrugated Plate Roof

Description

MRA Contributing Editor Martin Tärnrot creates realistic corrugated plate roof for buildings in a layout. Numerous ways to create it exist—the advantages of the method presented in this video are that it comes out self-adhesive and that the method is valid for both glass-fiber semi-transparent roof and corroded plate roof.

(Another method for making HO-scale corrugated metal for building roofing and siding is in this linked video.)

MATERIALS

The base material for creating this HO-scale corrugated metal roof is a 3M product called Micropore, which is used to make Band-Aids, so you can buy it at a pharmacy. The tape consists of a large amount of non-woven fibers. With Micropore, you can create both corrugated glass-fiber and plate roof.

We also need a template to copy the shape of a corrugated roof from. Here, Martin uses Evergreen 4526. He places a piece of tape over the Evergreen styrene sheet, then with a toothpick pushes the tape into the recesses in the sheet. Next he paints two layers of Elmer’s Construction Glue over the tape, which absorbs the glue.

PAINTING

To achieve a metal appearance, Martin uses Liquid Silver acrylic paint from Vallejo. After one layer of paint, Martin creates two washes, one iron red and the other black-brown. The washes will float into the recesses of the roof. After a few minutes, remove the excess with a Q-tip.

FRAME CONSTRUCTION

The frame for the HO-scale corrugated metal roof is made from 3D-printed styrene profiles that can be downloaded for free from Model Railroad 3D on CGTrader. (Search for Model Railroad 3D.) After you have painted the Micropore, cut the piece of roof and affix it to the frame with adhesive.

If you need or want to build a complete shed, not just a frame, we have a video about that too. Check out Martin’s tutorial about scratch-building a shed with corrugated metal.

    Martin mentions using this method to make fibre glass green roofing material but there isn't any mention. I'm guessing different paint, maybe a clear acrylic medium instead of the Elmer's white glue and a transparent green paint instead of the metal, but I'm just guessing.

Hello, and welcome to a "Model Railroad Academy" video. In this video we will create realistic corrugated plate roof. Ja, there are numerous ways to create this popular theme of roof, of course. I would say that the advantage with this method, which will be presented in this video, is that it comes out self-adhesive, and the method is valued both for glass fiber semi-transparent roof and the good old corroded plate roof. We will use a product from 3M, it's called Micropore, as base material creating these plate roofs. This product is used to make Band-Aids so you'll find this product in your pharmacy. The tape itself consists from a large amount of nonwoven fibers. With this tape you can create both corrugated glass fiber and the plate roof. We also need a template to copy the shape of a corrugated roof from, so in this video I'm using Evergreen 4526, which is the pattern of a plate roof, corrugated. And I just peel a piece of the tape off and put it onto that styrene sheet, and then I use a toothpick to push the tape into each of the recesses. With that done, I just paint Elmer construction glue. This glue is absorbed by this fibery material and after the second layer, I have a glossy surface and then I can start to paint this. The tape with the glue is very thin so if you want to avoid any light shining through when ready you should start painting with black paint. Then to achieve a metal appearance I'm using acrylic paint, this one from Vallejo. I really like that metal paints now are available as acrylics. Back in the days, they were only oil-based paints. Now we're gonna create two washes, one is kind of iron red whilst the other is more towards black-brown. The wash will float into the recess of the roof and once a few minutes had passed, then I removed excess paint on the edges with a cotton swab. The roof construction itself is made from 3D-printed styrene profiles. This is a huge set of, I think, 69 different profiles which can be downloaded free of charge from Model Railroad 3D and you find that on a site called CGTrader. So once you glued that together, painted it, it's just to cut the piece of that roof you just created and with the adhesive, you just put it in place on that construction and you see it's a very thin and nice looking roof. All right, so you can prepare for both making large Band-Aids as well as you're preparing to make corrugated plate roof for your model railroad in the same purchase. That's something, isn't it. All right, I hope you have use for this method presented in the video. Thank you very much for watching, I'll see you in the next one.
