Old holes in the clinker wall

An old wall lamp in the backyard at the clinker house wall is to be moved, the old holes are then seen and should disappear.

Here is my tip:
It does not matter what color the clinker have, it is important only there is the color in the spare pile of clinker from the wall, looking for the appropriate and go into a wind-protected room, put the clinker now in a clean shoe box, take the drill with a stone drill and diligently drill many holes in this stone, sense of the thing is, the accumulating Bohrstaub (drill dust). Put about a heaped teaspoon of it in a tin (film can), add about 10 drops of ACRYL clear-lime-silk matt water-based and stir until you get a thick paste. Carefully put this paste in the old holes, but really only the holes.

Let the filled holes dry for 2-3 days and try to find the old holes, if you have done everything right, the search will be difficult. Whole broken house corners on the clinker I have already repaired!
