Polyfilla vs caulking

[nufcmark]

I have a couple of cracks in a wall (emanating from the corners of an isolation switch). Not are about 250mm lond and about a mm wide. the wall is plaster on block. Woudl I be better filling them with Polyfilla or decorator's caulking?

Polyfilla can be sanded, whereas decorators caulk can't....thats used for filling on top of skirting boards etc where you can smooth the stuff with your finger. Polyfilla for you! Press it in as far as you can then sand down when dry. Open the crack out a fraction if its really fine.

If the crack is deep, I also find decorator's caulk suffers more with shrinkage. So you'll be left with a hollow when it dries.

Agree with Burnerman - polyfilla better for your suggested issue.

Id use Tetrion all purpose or Easyfill - theyre easier to rub down..

If like me you have an aversion to filler dust that sticks to absolutely everything them go for one of the newer light weight fillers,

eg

Unlike the cellulose based fillers (eg Tetrion powdered filler etc) the dust from these fillers is easy to clean up.

Easy to sand and allows for slight movement

Omw yes,forget to mention it, Red Devil onetime filler is the absolute dogs b*****s, Ive been using it for years, pricey but great stuff - slightly flexible too ..
Not suited to larger areas needing skimming though (unless youre rich )

Have you seen the prices at TLC-Direct???

I haven't seen it that cheap since Nu-Line w.11 used to flog it at £13.75 (ages ago)- its about £21 in my local merchants

Toupret Elafib Flexible Filler is also very good for movement cracks:
