How should I fill gaps in wooden skirting board etc?
If you only need it to last &quot;a year or so&quot;, use Playdough, chewing gum, Bondo™, duct tape, cement, lime or whatever the heck you want. If it falls out in 6 months, fill it again - this only has to last a year or so, right?
If you want to do it right, then use a quality wood filler. If you want to slap in whatever product you have sitting around the house, then slap it in.
The same holds true for fixing the holes in &quot;etc&quot;. If it's just temporary, use whatever you've got on hand. Heck, you could probably make wood filler work just fine in a plaster wall if it's only for a year...
