Crack Filling.

Hi All,
I have a few small cracks to fill in my internal walls, near cornices etc and was wondering what best to use. Acrylic gap filler or flxible silicon or what? All comments gratefully received

There's some stuff at bunnings which i use a lot. I think it's called One Time , or something (I'm not home at the moment but can check later). It's pre-mixed and very fine making it great for small gaps and hairline cracks. Great for this sort of thing. I always have some in the cupboard. If you don't get any other advice, I'll give you the name tonight.

Other than that, there's lots of premixed stuff at Bunnings. Go for a wander around, it's a good excuse. ;)

I just use your basic polyfiller. Seems to work for me....

Thanks guys,

What about expansion and contraction though?

acrylic filler for gaps between eg cornice/wall/ceiling; arch's/walls; skirts/walls etc, sandable filler for gaps/cracks in walls. acrylic filler isn't sandable so the repair line may be visible.
I generally use a total joint compound or spakfiller heavyduty.
Cheers
Michael

I reckon if you use a solid filler which won't expand or contract, then the crack opens again. Flexible fillers stretch or will poke out if compressed. Either way, if it moves again, you have work to do.

So true.

Al :D

I've gone with polyfilla mirror finish. We'll see how it goes.

I guess he uses it one time there, one time somewhere else.... ;-)

Maybe Phil can help?

Problem with the solid type polyfilla "mirror finishes" is that they look great for 6 months but then as house moves due to drought, heavy rains, whatever, they crack up again.
I find the acryllics/silicones last far longer,and have that inbuilt flexibility lessening risk of cracking or bulging. In fact some are ok after 5 years but I find it very difficult to achieve the same standard of finish with them as I can with the solid types.
