Upstairs, I have a 50 cm x 100 cm approx. mortar patch.
Old house, I presume there was a fire place there because it is on the outside wall where the chimney is.
The mortar is sound but has a crack.
Yesterday, I gave it a skim of ready mix post mortar and mixed in a some lime to lighten the colour.
This morning, pleased I'd done a great job. It looked solid and sound.
Don't laugh - I cleaned up the area with vacuum cleaner and the whole lot disappeared up the hose.
Tips and encouragement welcome.

Re: mortar skim patch
It sounds like you did not wet the wall sufficiently before you put the new mortar on. What happened is that the wall drew all the water out and the mortar did not harden or bond properly.

Re: mortar skim patch
The said area is on the floor surrounded by floorboards.
I did dampen it but maybe not enough.
Wondering if there is a sealer I can paint on after the mortar has set?
I will have another go with more water.
