Spackle and MDF
« on: August 21, 2019, 03:01:35 PM »
I'm not the biggest fan of MDF buildings, but haven't been able to find any decent resin Afghan huts for my 20mm Moderns project so alas... Sizing up the kit, I realize to make it look like a "mud hut' I'll need to texture the walls of the kit with spackle. My question is, will this create noticeable or substantial warping to the MDF?  ???

Try to keep it as thick as possible without adding water.

For added security, you might consider putting on an undercoat of spray on base paint or PVA glue, to make the surface watertight.

But I reckon it will be fine, as long as there is not too much moisture in the spackle.

Imyself  have used ultra light gap filler for stuff like this and that always worked just fine. You can even give it different textures as desired. For mudbrick or wattle and mud walls, I'd suggest applying a blob of the stuff and then spreading it out simply with your fingers. Messy? Yes, but it will also provide very natural results.

It's also sandable, should you require to take some of the biggest protrusions down a bit.

Personally I don't use plaster. I use premixed tile adhesive and grout. It's a lot less likely to scare the mdf. Plus it stays put much better than plaster. Also it sands and carves relatively easily.Unlike plaster it doesn't object to washes of colour.

Ditto on the rattlecan base coat just be sure to cover the edges.  A light coat of filler on top will not warp it.

I use the grout adhesive premix on MDF and have never had a problem with warping on buildings.

Textured basing pastes - I use them on buildings all the time.
Vallejo muds are good, Golden or Liquitex make pumice gels that are great too.

This is the stuff I use. It comes in tubes and tubs. Started out with the tubes, but quickly switched over to the tubs, as I was using quite the volume at the time ;) 

The only thing is that the stuff in tubs, when not used within a reasonable amount of time, tends to harden in storage, as the lids are probably not airtight enough. But after a bit of experience, you'll be able to gauge how much you'll need. besides; it's cheap enough not to worry too much about it...
