Not strictly a workbench project as everything has been done in situ on the layout but I thought this might be of some use to others.

I recently renewed the entire platform structures at Treheligan station as the Metcalfe card in use had started to shrink and blister slightly after three years. I reckon that's not bad for the outdoor environment but I have replaced all the card with Wills plastic sheets and will see how they go.

The product used is Wills "York Stone" which is available in platform packs which include brick facings and stone / tile edgings as well as sheets of stone pavers.

The pavers are supplied in a nondescript colour of "hangover puce", the bricks are bright red and the edgings are in white.

All were very easy to cut, shape and lay given that I have retained the underlying solid balsa construction.

Then came the "de-plastication" process.

First the stone sheets were painted with two coats (to achieve a good even cover and adequate opacity) of slightly thinned grey acrylic.



When completely dry I then prepared a thin slurry of colour as I wanted to create an effect of having no two slabs quite the same shade. I have mixed beige, warm white, fawn, burnt umber and black in here and thinned it to a milky consistency. It is not fully mixed as I want to retain the ability to add stronger patches of one or another colour as I go.



This is painted onto the platform one slab at a time and in a fairly random order. I found that with a loaded brush I could do about 10 - 15 slabs at a time (anywhere on the platform - it needs to look random) and then come back to reload the brush with a slightly different blend of the colours. A few slabs were left in the base grey.



This needs to then thoroughly dry out. I gave it overnight. Next sprinkle weathering powders across the surface, here mostly black as shown but with a few touches of brown, beige and even orange being used!



Lightly brush the powder to cover the whole job and note it doesn't matter if it's uneven and might actually improve the finished look if it is.



Then the fun part! I took a square of old T-shirt fabric and rubbed quite hard to blend the powders and buff the surface to a low sheen. This is where having solid wood underneath came into its own - hollow plastic structures will need a gentler touch!



The finished stone slabs on the platform surface now look random, used and unevenly weathered. The plastic has a slight surface texture which helps to create the effect of uneven wear as shown. While some areas have weathering powder between the cracks others have had those wiped clean and look more like a pale mortared joint.



The end of the completed platform showing the weathered track through platform 4 and the rest still to do.



Entering platform 3 at the "London" end with the edging strips having received a coat of "warm white" acrylic.



For the sake of completeness here is the original colour of the brick facings.



These were first painted with a rough mix of acrylic reds to soften the colour to a "brickier" shade and then have had black and brown weathering powders applied quite liberally.



The island platform 3 and 4 is done; the main platform 2 and the bay platform 1 await my attention through the weekend.

I must say Rick, that looks very good! Do you have to seal the surface with anything, or will it hold up over time just like that?

At this stage those are unknowns.

The work isn't sealed at this stage and I'm a little reluctant in some ways to overspray with something like Matt Cote (although I could do so quite easily) just in case it affects the finish.

On the other hand this is all outside and while there has never been any problem with rain or moisture in that part of the layout the finish is powder over acrylic and has a potential to be affected by something as simple as a frosty morning (very rare) or extreme humidity (uncommon).

I shall really have to wait and see. And I may yet get the airbrush and Matt Cote out as insurance.

:hmm
