What about a stipple coat of rend aid then a scratch coat with OCR with mesh or mesh in top coat?

If you get any loose brick face off the stipple coat will suffice and then dub out as you where needed just let that set for a few days before topping.

If you can dub out first, what you don't want is a mix of Rend Aid and Dubbed out areas with OCR. If you have to Dub out over the Rend Aid because for example you are going over engineering etc. Then Rend Aid over the Dubbed out OCR.
OCR has no waterproofer in it...and doesn't wet down well. So you can imagine what happens if you go over a mixed background OCR and Rend Aid!

It's different with OCR over OCR it pulls in quick I wouldn't recommend it.

Bricks were bad and some loose.
It all ended up needing a scratch coat it was that rough. Mortar joints empty big holes and loose bricks etc...
So looks like scratch coat (done) then rendaid/ mesh (weber tech again) then top.
Done plenty of mono before but by hand.
This machine work is a different ball game I'm just getting used to...

Looks good but it depends what finish he is having if floated OCR don't go over the OCR with OCR. I've done it and it dries to quickly, you won't keep on top of it on a warm day. I dampened it down first to.
