Rock face
« on: February 21, 2017, 01:36:57 PM »
How I propose to make a rock face back scene :-

To make a rock face, along my back board.

cut a piece of MDF Board, to fit along the back.

Mix plaster in a bowl.
And cover the board.
When tacky make the rock face :-
By dabbing the plaster with a damp dish cloth.
Add grooves with a tooth pick.

When dry mix grey paint and apply, all over.
Then mix brown, in the same bowl, and apply to selected areas.
Then wash out the bowl.
Mix some just brown, then apply to selected areas.

Mix some PVA glue, adding some washing up liquid.
Brush over selected areas.

Sprinkle over some woodland scenic scatter, various colours !

There are many different approaches, depending on what type of rock you wish to represent and what materials you use.  Definitely develop your own method which works for you.

I use polystyrene blocks glued with PVA and carved with an old kitchen knife and/or an old hacksaw blade, to create rough lumps of shape. Then cover with plaster bandage to give the final plaster layer something to adhere to.

For the final plaster layer I suggest you mix black powder paint in with the dry plaster powder, to give your rock some pre-colouring in case it gets knocked or cracked.  Experiment with small quantities first, to see which ratio of paint to plaster gives a suitable base colour when dry.

I find it useful to work with the board tipped at 30-45 degrees, and after creating the main rock faces I sprinkle more paint/power mix over the wet plaster to give a bit of texture, allowing some to fall to the base of the rocks for loose scree etc.

Have fun with your rocks!

Something else you might like to consider are the Woodland Scenic rock molds, there are various different sets to choose from.  My lad used them and got some nice looking results on his 009 layout.  Again, pre-colour the plaster as part of the mix.

You might find pre-cast molds an easier way of working if you're constrained by your backscene board?

Scrunched up kitchen foil can provide interesting variations press it onto the plaster to mould surface

Yes, as Ian says crumpled kitchen foil will give you some useful effects.

Once you've got your base colour, an airbrush is great for adding some highlights and variations, then use very thin washes of brown, black, dark green and other suitable "dirt" colours to run into cracks and features.

You won't need to use a detergent / surface tension modifier, just have a blob of PVA in a bowl, dip an old paintbrush in water and then into the PVA, and apply thinly where you want to have grass and other growth, eg. typically the more horizontal parts of the rock.  Sprinkle your chosen scatter on the gluey areas.

There are some excellent tutorials on such things on Youtube, created by war-gamers.

also buggie/birdcage grit is great for rock's/boulders that have eroded down the rock face .

I think these are brilliant. However, if you want a few different shapes and sizes they can get pretty expensive at £7.50 a pop but the results are well worth it. I Just bought some more molds today just so the shapes aren't repeated.  :thumbsup: :thumbsup:

Hi,

Not sure if it's just me, I am a bit worse for wear this morning, but what am I looking at here ?

Looks like a blur with a reflection of a computer keyboard at the bottom of it.

Some trees can provide very effective chunks of bark which have all the natural variety that WS rock moulds can't provide cheaply.  Bark is light, is easy to fix in place, provides lots of crevices and ledges for foliage, is cheap and gives an extra interest to walks in the park!  I'll try to post a picture, though I've not got to the stage of fixing the Teifi gorge yet.
Perhaps the proof that there is intelligent life in outer space is that they haven't contacted us.

In the sixties and seventies, model shops used to sell cork bark, which still looks OK in small doses, I reckon.
