Hi again

The end really is nigh now as I now have a base to sit it on. Not quite what I had in mind though as I chickened out at trying to produce a 'stony' effect

I bought this grass effect mat at Telford last year along with another with slightly darker and somewhat longer tufts. It's the first time I have used anything like this and was not sure how it would perform. It turned out good in some ways and not so good (for me) in another....
The mat was about 60mm longer than this - this was cut to fit the base .....

..and the residue used as test pieces, none save one anything near what I'd hoped for.

I had hoped the Polyfilla sub base would have seeped through the 'Scotchbrite' like sub surface of the mat to fill in between the tufts but this proved extremely resistant to that even when prodded. Soaking the mat improved things slightly but that in effect diluted the surface of the Polyfilla and the resultant very thin watery liquid soaked through and wicked up the tufts rather than just soaking into the sub surface.
This was the best result of a poor lot and close to what I had in my minds eye but still not what I'd hoped for.

I applied PVA on top in between the tufts sprinkling sieved cat litter over then shaking off the residue. This looked good to begin with but the cat litter gradually soaked up the pva and holes began to appear as it dried. The litter dust also had a pigment effect on the tufts.
The decision was made to use the mat as is for effect rather than realism at this stage as more experimenting is required on this. A base was cut from the usual MDF and a pocket milled in to take the mat. 'Green Putty was then spread so as to give an undulating surface.

The instructions with the mat suggest painting beneath - this was vallejo acrylic primer

Once dry a thick coat of Titebond PVA woodworking glue was spread and allowed to semi dry before laying the predampened mat on top

The mat flowed easily over the low contours of the putty without lifting in the low areas but has shrunk a very small amount around the edges. Due allowance will be made in future


At this stage I don't want to risk spoiling this with attempting to fill in between the tufts so will stick with this as is. I may just add a little colour here and there and perhaps lighten the tops of the tufts with a spot of dry brushing to break up the uniformity.
Next session will see this project finished - I had forgotten the air pump propeller so that has to go on, the underneath of the tailplane still requires weathering and there's a nameplate to do but it
is at an end.
If anyone has any experience using this kind of product and has anything to add please, please do so - base work has never been a strong point particularly where any kind of 'foliage' is concerned so any thing you can add will be more than appreciated
That said however, I hope this little foray into the unknown will be of interest to someone
