Spackling compound


Why does the spackling compound crack? What can be added to the compound to prevent cracks and shrinkage?
Thanks

Spacking cracks when the hole being filled is too big. No big deal. Use it, let it dry, go over it if you have to.

Spackling compound


Spackling compound cracks, because it's water based. anything with water will shrink as water dries out. it cracks more if coats are too thick! better to use more thin coats than try to fix with 1 or 2 thick coats adding more water, makes for smoother coating, but adds more water to need to dry out. I usually add about a quarter of water to a 5 gallon bucket and mix thoroughly.

as usual, my own thoughts

good luck

Spackling compound


Spackling is made for filling small holes like there pictures were hung. If you trying to repair cracks in dry wall then you need to apply joint compound not spackel then dry wall tape then apply a thin coat of drywall compound over that once dry knock off the high places and apply more joint compound with a wider drywall knife. The last coat gets sanded and a really thin coat of drywall compound. Let try and lightly sand, prime then paint.
