Clearly the course this guy did only briefly covered “external expired coatings, their uses and application”.........
He obviously was clever enough to buy a book covering the subject. However, I surmise that the page after scratch coat, the one that said “apply the tyrolean mix to the resultant flat surface”, had been torn out, along with the one that said “apply several thin coats of the tyrolean mix from differing angles, taking care to cover the beads evenly”.
So. I think we can all agree that this bloke has made a fine effort, and that it’s not his fault.
