You will be all familiar with the famous caulking method to make beautiful flexible wargaming mats. However, this technique does not only come in handy to cover an entire gaming table, but can also be used for scatter terrain, such as rough terrain, roads, villages and even hills. It can also be used to create a very versatile photography mat.
In this first installment I focus on making some flexible rough terrain featuring some rocky outcrops, brush and small bushes. I took my inspiration for this piece from ekimdj, who not only has a very nice blog, but also wrote a tutorial for flexible desert terrain on the Sweetwater-forum, so if you are able to read German check it out (it is pretty picture heavy, so you can follow it easily in any case).
This tutorial will also come in handy if you want to learn how to create basic groundwork, flexible or not. This technique can be applied to a small base or an entire terrain board.
Per usual I will give an overview of the materials you need, followed by detailed step-by-step instructions and finally some ‘action’ shots showing off the piece’s flexibility.
The most beautiful terrain piece is worthless if you are unable to place miniatures on it, assuming you don’t model some impassable terrain like a lake or cliff. However, if you make your terrain too ‘gamey’ it pretty much will be flat and featureless, gentle hills turn into staircases and everything will look very stylised to accommodate regiment bases and the likes.
There is no real solution to this dilemma, but as is often the case in life: in taking the middle ground one fares best. Keeping this in mind I tried to create a nice looking piece of rough terrain that can still accommodate regiments or single miniatures, but is a bit more interesting than a featureless plain.
To spice it up a bit I also decided to embed some magnets in the flexible piece, so that one can place trees and other features without them falling over all the time. This way one can make full use of the flexibility of the piece while not being limited by the fear of trees falling over.
My own addition to ekimdj‘s concept is the use of some ‘Self-adhesive fibreglass drywall joint tape’. This tape, or to be more precise fibre glass netting, does lent some impressive tensile strength to the caulking. I tried to rip a test piece apart and using all the force I could muster I was not able to rip it. This also works if you encase extruded polystyrene. What formerly could be easily ripped apart is afterwards very strong (but not crush resistant, for that you need a resin shell or something similar).
What you need
For the groundwork:
- Self-adhesive fiberglass drywall joint tape. About 1.5 metres (if that) to strengthen the gap filler. A roll costs about 25.35 NZ $.
- A tube of caulking/ gap filler. I use Selley No More Gaps. You could use already coloured filler, but that is not necessary. A plain white no-name brand will do. You won’t need the entire tube, maybe 50g or so of a 475g tube, depending how thick you apply it. A tube costs about 4.50 NZ $.
- Different kinds of sand or soil, ranging from very fine to coarse.
- Bark pieces and coarse cork pieces to depict rock outcroppings.
- Different shades of brown and grey acrylic paint.
- Neodymium magnets (optional).
For weeds, brush and moss:
- MiniNatur grass tufts and birch foliage nets. I used a selection of autumn grass tufts. The foliage nets can be used to depict floor creepers and bushes.
- Static grass. If you have different brands mix them all up for a more nuanced and realistic appearance.
- Matte spray varnish to reduce the shine of the static grass. I use Tamiya Flat Clear.
- Brown acrylic spray paint to slightly darken the tufts or alternatively a brown wash to dull the shine of the tufts and grass.
- Fine turf e .g. Woodland Scenics range of fine turf in dark green or any other fine turf. This is basically very finely ground coloured foam. We will use this to depict moss.
- Some fine sprigs of seamoss (optional).
- Wood glue.
- Dark or medium green, yellow and beige acrylic paint. Vallejo Umber wash.
- AK Interactive Grime/Slime effect paint (optional).
- Dried basil to depict fallen leaves.
- Assortment of dry tea to depict roots and leaves.
- Caulking gun.
- Plastic bag.
- Scotch tape.
- Small strainer.
How you do it:
- Cut as many pieces of fiber tape as you need to cover the base of your terrain piece. Slightly overlap each strand of tape.
- Shape the edge with a pair of scissors to achieve a more natural appearance.
- Cut the plastic bag open, glue it to your work surface with some scotch tape and place the fiber tape on the plastic bag.
- Now follows the fun part: Squeeze some of the caulking onto the fiber mesh. Using gloves and your fingers spread the paste until you have covered the entire piece. You must use gloves for this step, as it will be near impossible to getthe the caulking off anything it touches. Given there are more fun activities than washing your hands for two hours (or your carpet etc.) it really pays to be careful during application. You can also use a spatula to even out and smooth some of the areas.
- After you applied a first coat embed bark pieces and the magnets. Just push them into the caulking and smooth the transitions out. I covered the magnets with a thin coat of caulking, Given they are rather strong this does not inhibit their ability to attract things. I use small bark nuggets you often find in the gardening section of your local DIY store. Put them in the freezer for some weeks to kill anything that may dwell inside and then cut them to size using a handsaw.
- After you smoothed out the caulking use a small strainer to drizzle different grain sizes of sand onto the terrain piece. You can also add some dry tea leaves to depict roots and dirt. Gently push the sand into the caulking when you are finished, but don’t overdo it, as you could leave an impression. You can also add some coarse cork pieces to depict bigger rocks.
- Let completely dry for several days. This is important. If you try to peel your piece off too early it might deform, so give it plenty of time.
- When everything is dry, peel your piece off the plastic bag and remove any sand that did not catch. Keep this sand for future pieces.
- Now we need to paint the piece. It is not necessary to colour the caulking. Adding too much paint can make the caulking brittle and given the piece is very flexible there will be no chips or cracks that could reveal the white base. Using different shades of slightly diluted brown acrylic paint apply a goodbasecoat. Through the different grain sizes and colours of the sand one can already achieve some variations as the sand takes the paint differently. You can also add a wash in some places at this stage to add more depth and colour variations. When everything is dry, you can also give the soil a gentledrybrush. Do not go crazy, a subtle dry brush will look more realistic.
- Next are the rock outcroppings. Using different shades of brownish-grey paint followed by a brown wash we already achieve some definition.Drybrush them withsuccedingly lighter shades of your base paint. Here it is important to not make the rocks too grey and to not overdo it with thedybrushing. Too stark contrasts will look unnatural.
- Time to add more interest to the rocks. Using some thinned down green paint or the excellent effect paint by AK Interactive, we add some green to the crevasses, giving the impression of some light moss. The AK effect paint is enamel based which gives you better control. You can also go back and rework an area with some enamel thinner on your brush.
- If subtle moss growth is the idea, then you can keep it at that, but if we want to depict a more humid environment some more moss can be added. Here I used my trusty moss paste (check out my Crypt of the Damned tutorial for details).
- After the moss is toned down with a brown wash and drybrushed we move on to placing some of the brush, floor creepers and tufts. Here we aim at placing the plants in a more or less random fashion.
- The vegetation is still a bit bright and has a lustre to it. To fix this we first spray a thin coat of matte varnish over the whole piece, followed by applying a brown wash to the plants.
- We do this with all remaining plants and achieve a nice naturalistic look.
- Now it is time to add loose static grass. If you have a static grass applicator you will be able to achieve better results than I did. I am planningto built one myself, but as of now I use a plastic bottle and spray the fibers in the thinned down PVA.
- Remove any excess with a vacuum cleaner (if you slide some old stockings over the hose you can even reuse the grass without getting it mixed up with dust). Repeat the process if you want denser growth. You can also add some dried basil to depict fallen leaves or different kinds of tea.
- Finally we have to tone down the lustre again using matte varnish. A brown wash in places adds some colour variations and will result in a very realistic appearance. As a final touch I added some seamoss twigs and MiniNatur foliage nets to depict two taller bushes. This is naturally optional.
Voila, you have a realistic looking terrain piece that can be used to depict rough going or even a small grove if you add some trees to it. The picture below illustrates that you can also depict gentle hills if you use it as a photo mat.
So, the big question is how flexible is this piece? Well, very flexible. A picture is worth a thousand words, so here we go:
I hope this tutorial inspires you to give it a try yourself. It is an easy technique that produces very nice results. There is no reason why one could not use it for villages, forest bases and hills. You could also combine different methods and have a solid core piece and only use the caulking to make the borders of a piece flexible. This way they can conform to your gaming mat or board.
