Adhered veneer is a facing, not a wall
Manufactured stone veneer is cast from cement and lightweight aggregate, coloured through the body, and bonded to the wall through lath and mortar rather than stacked on a foundation. Nothing above it rests on it, and it carries no structural load.
That is a genuine advantage: it goes onto a normal framed wall without the footing and wall ties that full-thickness masonry needs. It also means the bond and the substrate are doing all the work, so preparation is not a stage that can be shortened.
It gets wet behind, and that is normal
Mortar and cast stone both absorb water. Wind-driven rain reaches the back of the veneer, and the assembly is designed on the assumption that it will. The job of what sits behind the stone is to catch that water and drain it back out at the bottom.
That means a continuous water-resistant barrier over the sheathing, lath fastened through into the framing, and a scratch coat for the stone to bond to. Stone applied straight onto sheathing, or onto a barrier with no way to drain, traps water against the wall. It looks identical on the day it is finished.
Clearances are not optional trim
Veneer is held up off the ground, off paving and off roof surfaces, and a weep screed at the base gives water somewhere to leave. The gap looks like an unfinished edge to anyone who has not seen a wall opened up.
Stone run down into soil or mulch wicks ground moisture upward continuously and freezes in it every winter. It is the most common reason we are asked to look at spalling stone and a damp interior wall, and it cannot be fixed from the outside without taking the bottom courses off.
Choosing it, and where to use it
Manufactured veneer is lighter, cheaper and easier to fit than natural stone, and the good ranges are convincing at the distance anyone actually stands. Natural thin stone costs more, weighs more and reads differently up close on a porch or an entry where people are within arm's length.
As for how much: stone tends to look most convincing where a real stone wall would plausibly have been — a base, a pier, a chimney — rather than applied evenly across a whole elevation. We will lay it out against your roof and trim colours before anything is ordered.
