Foundation Skim Coat


What would be the best way to get this mess looking like new again.

There is 5-6 spots like this large building probably built in the 50ís.

Besides peeling all the loose stuff off , what kind of prep and mix?

It may be worth taking the scratch coat off as well as it doesn't look scratched. Use 1/1/4 lime/cement/sand for the scratch coat and scratch it out horizontally.
1/1/5 for the top coat. Use washed plastering sand rather than building sand.

Couldn’t I just grind some scratch into the coat?

It would help, but the scratch coat needs to be in good condition itself and not blown from the brickwork or flaky, sandy etc.
This type of stuff can help adhesion.

Sorry, I haven’t busted into it yet. I am assuming (hoping) that the scratch coat is tight.

If it starts falling off with the rest of it I wouldn’t even think about grinding grooves. Then again if it’s a rock, why mess with it?

Thanks for the link.
