Brick veneer over scratch or brown coat?
 
I plan to remove the existing brick wall.
I'm pretty sure there's only a scratch or brown coat under it.

so I can stick brick veneer with exterior grade thinset mortar directly on that, right?

Does veneer need to be anchored to the wall with anything other than mortar?

Are the existing brick actually clay thin-sawn brick?? If so, yes, the substrate "should" be fine, as long as you don't cause too much damage getting the existing brick off. If the brick are faux, like a fiberglass substite or the sort, all bet's are off........

I don't really understand your question, but they look like real antique bricks to me.

They stick out past the window about 3-4 inches.

House was built in the 1960's, so 99% chance they are real bricks.

If they're real full veneer brick, I doubt there's a scratch coat behind it.

Are the new brick going to be a full brick as well? You don't "stick" full brick to a wall, you stack them and let gravity and wall ties take over............

"Veneer" is a relative term. An adhered veneer sticks to the wall, which would be scratch/browncoat. Traditionally, "Brick Veneer" means full size (3-4" thick) that are set on a brick ledge and tied to the back up wall with brick ties. There is normally an airspace between the veneer and the backup wall.


What you have is almost 100% a traditional brick veneer.
