Accurascale Cemflo. Step 6 - Finishing Details.
Mick Bonwick commented on Mick Bonwick's blog entry in Mick Bonwick's Blog
Thanks, Steve. I have used a dark grey pigment, MIG Volcanic Ash, lightly dusted around the loading hatch area. I have now taken a photograph but not yet processed it. I'll do that and post it here in a few days time, when I return from a trip to darkest Sussex. https://airbrushes.com/product_info.php?cPath=400_405_195_199&products_id=22721&osCsid=vsqdvlt48sjhc9b27abi3cldu1 -
Accurascale Cemflo. Step 6 - Finishing Details.
Mick Bonwick posted a blog entry in Mick Bonwick's Blog
Final touches include the wiping of the pigment brush, which still has a residue of light grey pigment on it, over horizontal and protruding surfaces. Note that this does not mean that the brush is dipped in pigment at all, we just make use of the miniscule traces that are still embedded in the bristles. A bit like dry brushing with paint. The Blue Circle board on the tank has also been rubbed with the pigment brush, in vertical streaks, to replicate the dusty buildup of cement dust. Only after the photographs were taken did I discover that I had broken one of the hatch latch handles. Be warned! I have now realised that I have not photographed the darkening process for the area around the hatches that arises from lubrication of the hinges and latches, and the vehicle is now with its owner. The second photograph below will show you how this appears, but on a much later PCA. -
Accurascale Cemflo. Step 5 - Underframe (Details).
Mick Bonwick posted a blog entry in Mick Bonwick's Blog
The holes in the underframe strengthening plates presented a small problem. How do you get an even coverage of paint on the solebars that will be seen behind the plates? I put the nozzle of the airbrush right up against the holes and sprayed through them onto the solebar. The consistency of the paint allowed it to spread far enough inside the gap to cover the whole area. The Railmatch frame dirt was applied first, to give an overall tint to the whole area. Wheels were done by using the airflow from the airbrush to turn the wheels and then applying the paint and watching the excess fly all over the inside of the spraybooth. Railmatch weathered black was mixed in with the frame dirt and then randomly airbrushed over the top to introduce a change in tone to the accumulated grime. The photographs show this much better than (my) words can explain: -

Accurascale Cemflo. Step 4 - Encrustation 1.
Mick Bonwick commented on Mick Bonwick's blog entry in Mick Bonwick's Blog
Portland cement powder would have been too dark (to my eye) and I haven't got any left from all my failed DIY projects - it went hard! I am attempting to show a scale effect by using a pigment that is lighter than cement powder, and it is also as finely ground as the real thing. The choice of using a sieve was present, but I decided to not use one, to see how well the pigment performed. I should have used the sieve! -
What colour do you use for a wagon roof?
Mick Bonwick replied to Brinkly's topic in Weathering, Painting & Transfers
Anything dark grey, but warmed up a little for some vans with a drop of tan or brown. Lifecolor Roof Dirt, Railmatch Weathered Black or Roof Dirt, a mixture of Revell Dark Earth and Anthracite, a mixture of Humbrol Matt Leather and Matt Black, anything that matches the photograph you're working from. -
It's the turn of the underframe. Railmatch Weathered Black and Frame Dirt are used in this case. A first layer of frame dirt is followed by a second layer of weathered black/frame dirt mixture, giving some variation of colour to random areas of the chassis.

Accurascale Cemflo. Step 4 - Encrustation 4.
Mick Bonwick posted a blog entry in Mick Bonwick's Blog
Cement dust builds up gradually on the tank sides, forming a crust as time and precipitation both do their work. In places the weight of this buildup is too much for the grip of the gunk on the metal of the tank, and lumps fall off. On the model this effect can be shown by using a cocktail stick, or similar precision tool, to chip away at the previously created mess. The pointed end will remove small areas at a time, or it can be used at a much shallower angle to reduce the height of the lumps more quickly than an old brush. -
He's simply checking that the cab door is shut.

Accurascale Cemflo. Step 4 - Encrustation 3.
Mick Bonwick posted a blog entry in Mick Bonwick's Blog
Once the Dullcote has dried, the pigment is well and truly stuck. Working with an old filbert brush, the mess is being reduced to smaller lumps by the simple expedient of rubbing the lumps down to size. The harder you rub the smaller they become. Notice the piece of paper in a nice shade of pink. This is being used to capture the powder falling off the tank, so that it can be re-used. -

Accurascale Cemflo. Step 3 - Couplings.
Mick Bonwick commented on Mick Bonwick's blog entry in Mick Bonwick's Blog
This is a weathering exercise, so functionality is not paramount. I understand the problem with the couplings and it's a shame about that, but I wonder how many of these could be placed in a train before the superglue gave way. I'm not in a position to test the theory, but from some of the posts I've seen there must be a few people around who can check it. -

The idea of using the Dullcote is to create a quick-drying sticky surface upon which the pigment can be plonked. Sorry for being technical. No attempt has been made to be careful where the pigment goes because the Dullcote dries very fast, and the pigment needs to land on it while it's still wet. You would have been amused had you been able to see me struggling to spray Dullcote, plonk (sorry again) pigment and take a photograph all in the space of 10 seconds. It looks an absolute mess so far, but things will improve. Honest! -

Preparation for the cement application. Materials to be used now are Testor's Dullcote and Lifecolor N. Europe Dust pigment. I searched through many pigments to find a suitable grey cement powder colour, and this one is the closest (to my eye) I could find. -
Not a weathering post, I know, but I thought that I'd remove the supplied couplings and fit the cosmetic screw couplings before proceeding. They look so much better that I took a photograph. Or two.

Accurascale Cemflo. Step 2 - Oxidisation.
Mick Bonwick commented on Mick Bonwick's blog entry in Mick Bonwick's Blog
Simple to use, straight from the jar. 16/17 PSI gives quick, even coverage. It is very suitable for fading colours, although a bit stark.
