Brilliant stuff - forget dot’n’dab
If you’re fitting plasterboard or skirting or any trim, forget mixing powder or using nails or screws or no more nails - use this. When it sets, it sets rock hard. I once “temporarily” fixed a bit of 2x4 to the ceiling with this - I could literally hang from that 2x4 and had to use a pry bar to remove it It’s looks expensive but it’s so worth it. Trust me.
