Mortar below sill of new door frame...

[John Smith Esq.]

Hi all,

I've just had this new door frame fitted.

Underneath the sill needs finishing off. A DPC was put on top of the pre existing bricks at the bottom and foam has been squirted in to fill the main space below the sill (see photos). I won't go into why this space exists or remains, too long a story. Now it needs mortar putting in to finish it off flush with the bricks and seal the space. What can I do to give it the best chance of lasting and not cracking etc? I have a tub of pvc and SBR, would that help?

Thanks

That step might cause problems as against wall.
I would of run a aco drain along edge around or gravel to stop splashing up and take away water.

The step isn't connected to wall, there's a gap. I just put two loose pieces of stone on top. Behind the step is some sloped mortar so any water can run out and then down the stones which fall away from the house.

How do I ensure the best mortar that will last without cracking?

I use the ready mixed although it's gray.
If I want yellow or red mix your own
