cultured stone veneer falling off house
Two pieces off cultured stone veneer on the front of our house - the bottom near a corner have fallen off during this past winter. Looks like the mortar came off the house, but stayed on the stone.
What's the best way to put it back up? Is there some sort of adhesive I can use or do I need to do it with mortar? Never done this sort of thing before.

If you can chip the old mortar off the cultured stone you can re-mortar it in place. Then, there is always the Liquid Nails solution.

First, determine why it fell off. Was it on the corner where expansion and contraction forces will "work" the joint? If so, cut out the corner mortar joint and replace with sealant. How was the cultured stone held in place? Are there corrugated metal ties holding the stone in place fastened back to a plywood substrate? Is the substrate in good condition, or has water leakage compromised it?
Liquid nails will probably function for a short time, but may not be a permanent solution.

I'll need to take a closer look to answer those questions. I seem to recall wire mesh underneath the mortar, but I'll confirm all of this this week.
thanks guys.

Took a look at this area. Part of it is foundation concrete and above that is wire mesh over some sort of sheathing. Can't see any "workage" - all looks solid. I didn't see any metal ties - at least not here. It's the only outside corner with stone, so I couldn't compare it with anything else.
In any event, what's the recommended mortar type for this? This will be my first job like this so any help would be great.
