Stucco & Exterior in Altadena
Stucco in Altadena run in a set order with full cure times between coats, for ADUs, rebuilt walls and recoats of the main house. Cedarline Design Build.
Curing time between coats sets the calendar for an Altadena stucco wall. The scratch coat has to firm up before the brown coat goes over it, and the brown coat needs about 7 days before the finish coat is applied. Rushing either wait locks shrinkage cracks into the finished face. On an ADU or a rebuilt wall of the main house, everything else in the order of work is planned around those pauses.
Before the scratch coat
Ahead of any plaster, damaged sheathing is replaced and the framing is checked for straightness. Windows and doors go in with their flashing. The weep screed is fastened along the base, then two layers of building paper are hung from the bottom up, each course lapping the one beneath and the lowest lapping the screed's flange. Lath goes on last, and the county inspects at that stage, since Altadena is unincorporated and its permits run through Los Angeles County Public Works. With some of Altadena shown on the fire hazard maps, vents and eave details on a mapped lot are settled before the walls close.
After the finish coat
Once the finish coat has cured, sealant goes around fixtures and the trim is painted. Sprinklers are switched back on only after they have been aimed away from the base. Gutters and downspouts are reattached last, with their outlets carried well away from the wall and onto splash blocks. For an ADU built at the same time as a recoat of the house, the two can share each stage, so their finish coats go on in the same week from one batch of color.
Stucco & Exterior in Altadena: common questions
It can, when the match is planned from the start. Sample boards are troweled in the house's texture and colored from a chip of its finish, then judged dry against the old wall. An Altadena ADU finished in the same week as a recoat of the main house matches most closely, because both surfaces come from one mix.
Sort the wall by what lies behind the finish. Small cracks over dry, bonded plaster are filled and color coated. Soft sheathing, rusted lath or brittle paper found in a test opening calls for new layers in that section. A sound but discolored or patchy surface gets a recoat across each whole wall plane, so the color reads evenly.
Here the county is the building authority, with Los Angeles County Public Works reviewing stucco and exterior permits. Cosmetic recoats often need none, while new lath and paper, sheathing repairs and the walls of a new unit usually require one. On a mapped fire hazard parcel, exterior details face ember-resistance review as well. We confirm the scope before the quote is final.
