Atheling I just use simple polyfilla powder mixed with water to the required consistency and then spread it onto the base. I let it dry overnight and then sprinkle a sand and grit mix on top over a slightly watered down PVA.
When dry I lightly sand away any rough edges.
I’m not sure why your bases warp as I’ve never had that problem myself.
Hopefully if you try the Warbases bases it might help. They are laser cut and quite strong. Worth using the craft knife to cut some criss cross grooves on larger bases as it helps stop warping and the filler sticks to the smooth surface better.
Don’t use cheap PVA. I get mine from B&M bargains in a yellow bottle. Lasts me ages.
Your more than welcome to ask any questions and glad to help if I can.
Let me know of this method works for you if/when you try it

Ah, I don't use the PVA watered down as I have had more warping issues if I do add water

I'm beginning to think that it just be the filler/spackle. It must shrink. I definitely use a very high quality PVA.

Which is what I also do! This is getting very odd- I must be going wrong somewhere but I cannot for the life of me figure out what it might be!!??

A mate did suggest using something called Modge Podge glue that is water soluble so I might try that without any filler/spackling at all.

I have had minor warping with some 30mm x 180mm bases, which I used for thorn bush barricades. I thought that I should have primed them, which I will try with the next batch.

I use Minibits / Pendragon for my laser cut MDF bases.

I might just bit the bullet and go for 3mm thick bases when basing anything large and see if that helps. Not my favoured method as you can really see the difference between 2mm and 3mm thick bases.

I should have said, I’m using 2mm bases, with 0.8mm magnetic sheet for troops, but no magnetic sheet for scenic pieces.

Ah.... that reminds me of a long forgotten technique. I used to superglue the magnetic sheets to the bases which seemed to counter some of the warping.

I used a very cheap superglue and if I remember it was a little messy.

I guess you know that these are available as self-adhesive sheets?

Yes, I superglued them anyway to get a stronger bond to avoid as much warping. I'm trying to find the models/stand I used to take a pic or two.
