The WWM lap is specified as one grid plus how many inches?

When installing WWM lath, the overlap length is defined to ensure the plaster can bond across joints and the layers stay continuous. The overlap is measured using the lath’s grid pattern, a repeat unit that tells you how much material is involved in each lap. The required lap extends one full grid plus an additional two inches beyond that grid. This extra two inches guarantees there’s enough overlap for the plaster to key properly and for joints to transfer stresses without opening up.

That’s why the correct phrasing is one grid plus two inches. A lap of just one grid wouldn’t provide sufficient overlap, while two grids would be unnecessarily long. One brick isn’t relevant to lath overlaps.
