Hi fellow diy-ers.
Noticed a few hairline cracks in the ceiling presumably resulting from temperature changes going into winter.
Was looking to diy repair. Any tips before I wing it? After bit of googling was thinking of going over with selleys spakfilla or similar using a spatula then painting over a few coats. Not sure if I need to prime after using the spakfilla.
Would appreciate any advice
Cheers
Hairline - I would rub some no more gaps in with your finger, wait a few minutes - prime and paint. You will never see it, not worth the hassle of sanding back etc.. will only make the problem more noticeable . Source - I am a builder.
Hey mate…thanks so much for the input. Appreciate the advice. Was trying to PM you but you have PM turned off. The existing paint is dulux ceiling white. Is the primer really required? Minimum size is 1L which is actually more expensive than 1L of the paint but will get it if it is necessary…
Can get away with no primer.
Do paint shops still do sample pots?
Bunnings do, you can ask them for any paint/colour in a sample pot, I think we paid $5 for some paint last year as we only needed a little bit.
Dont use hard fillers - NO WAY!
They will crack in no time
Use the "white" gap fillers in the long tube sold next to the silicone tubes.
They are very cheap and water soluable so you can fill the crack then wipe with a wet sponge to get a nice clean finish.
Then paint over when dry.
Its the only way, ask any painter or builder
Thanks. Can you suggest a specific filler?
Depending on how big the cracks are, I would suggest plasterboard joint compound instead, assuming your ceilings are made out of plasterboard like normal homes. It's essentially the same material as the plasterboard, so it will have the same thermal expansion properties.
You should prime, but for very small patch work it should be ok without.
Never had any in the ceiling but on walls I just use Sika fine surface filler with spatula or putty knife etc, let set, sand, thoroughly remove dust (I generally wash with sugar soap then once dry wipe over again with a microfibre to ensure all dust is gone) then paint without priming.
