I've got 3 filling jobs to do on a house I just had built.

The first is in a concrete wall (block and morter)wich had 2 10mm holles drilled in it that were never used.

What kind of filler should I use.

Next I had a concrete wall same as before which had a doorframe set in it.I got the builder to replace the doorframe.Which he did and re-mortered the gap between the new doorframe and the wall but when the new render dried it left a large crack between it and the doorframe.

I need to fill this gap.What filler should I use.

Thirs i have a room with drywall(plasterboard)sheets on the outside with light coming through in spots.I'm not going to render these walls I just want to fill the gaps and paint it.

What king of filler should I use.

Are they all inside your house?

If so I would simply use a flexible decorators caulk. Its cheap, can be painted over and quick. you can buy it in a small tub or a caulking gun and tube. I would use the gun and tube it always comes in handy.

if its outside, you may need to upgrade into an external weatherproof frame mastic. Go for one that doesn't shrink (in 6 months) but they all do eventually.

they even have the equivalent of polyfiller here, in a small tub but in fairness they give you a flat spatula to spread it so ok for cracks but a nightmare for holes!

Cheap, easy to use (photo from HomePro).

All 3 are outside.

That wall putty sounds good,can it be used outside,will it shrink,is it good for the

dryboard too.

That's what I use. It shrinks a bit - so one application sand a little bit and then apply another - then sand or scrape to level.

Yeah, the Bosny stuff works well for in and out.

Easy to use and reasonable cost.

Stays a bit flexible.

Thank you.
