I'd like to fill two small holes indoors and I only have (Wilkos) exterior filler to hand. Is there any reason why I couldn't use it indoors? It does say explicitly that it's for exterior walls and while I could understand that interior filler might not hold up outside I wouldn't expect the opposite to be true.
Can I use exterior filler indoors?

External filler tends to be cement based, and internal filler is plaster of paris based, so it'll depend primarily n what you're filling. No problems on a wall, might not be so good in wood though. Why not just give it a go.
Okay, thanks; it's for walls; I'll try it.
Yes, I've used it, just a little harder to sand if necessary. In fact I'm sure I had a small box of one once which was marketed as interior and exterior before - so basically just exterior plaster in a different box!
