 Sweep. Sweep away the dust and dirt left over after the plastering of the entrance to the bathroom of the top flat two days ago . Gather all the stuff that had fallen upon the floor, bits of mortar, bits of wall. Use a shovel to put them all into a bucket.

Examine the work done, and then unscrew the piece of wood that had been fixed to the wall as a guide. When the plank has been removed, the new plaster has a neat edge, just there where the doorframe will be. The main thing is that the work is straight and plumb.

Take the piece of wood, and with a level fix it to the opposite door jamb. To act as a guide for further plastering. Shorten it first with a saw, five millimetres, it is a couple of millimetres too long. Cut further bits of wood, jam the vertical guide in place so that it will hold.

Six litres of water and forty kilogram of mortar, all mixed up with the electric mixer for mortar bought from a foodstuffs chain. Mix it up, realise that the result is too dry. Add two hundred millilitres more water, and that is better. The new mortar smells different from the older stuff, probably a difference in the manufacture. It also takes more water.

Make up a small bucket of extra sloppy morter, and spray it onto the naked wall behind the new guide using a mortar trowel. The sloppy stuff sticks to the wall, the dirty white surface turns gray, almost lunar. Keep it up until the whole surface is covered.

And then, to the other side of the wall, use the normal mortar to plaster over the rough layer left from yesterday. Cut another guide and put it on the floor, and repair the that area, covering a wooden beam. Using the power screwdriver fix many screws with to act as anchors for the mortar. Fill a few holes, and that is the outside done. Then the inside again, throw mortar at the wall filling the gaps behind the guides.

When all the mortar is finished, wash the tools and sweep the floor.

What a waste of time, it would be better to take pictures on the street. Leave plastering to plasterers. But there are simply no builders available, and the plumbers will be there to look at the heating in two weeks.
