Dust Mitigation

The customer took her index finger and ran it across her grand piano in her living room and asked me if I could see the dust streak.

Q. Stiffening a Pony Wall for Tile I’m framing a new slab-on-grade home where the master shower is enclosed by a pair of 6-foot-tall pony walls that are connected to the flanking walls only at their ends.
