Hi all,
Want to preface this by saying I am very new to the whole DIY thing.
A while ago we had our multiple split systems replaced with a ducted system. I've started to patch up the holes but am now considering I may not have approached this correctly. For the larger holes I used Earl's All Purpose Multifil over the expanding foam. Looking at some of the guides on here it looks like mortar and topping compound should have been the way to go.
Would it be best to remove the expanding foam and multifil and patch with mortar and topping compound or will it be ok to just go over with topping compound?
Cheers
