Stucco protects the envelope and sets the look of the facade. Properly built assemblies manage water first—then carry a durable plaster finish that breathes, cures well, and holds its lines at trims and openings.

Overview

• Scope: new stucco assemblies, targeted repairs, full re‑stucco, fog and color coats, elastomeric recoats, and EIFS (synthetic) patching.
• Goals: dry, well‑detailed walls; straight beads and joints; textures that match; finishes that resist cracking and shed water.
• Surfaces: framed walls with sheathing, CMU/concrete, existing stucco, and EIFS—detailed per substrate and climate.

What This Service Includes

• Assessment & prep: check sheathing, WRB, flashings, and previous coatings; locate moisture entry and repair substrate as needed.
• WRB & flashing: housewrap or fluid‑applied WRB, shingled laps, weep screeds at base, pan/head flashings, and kick‑outs at roof intersections.
• Lath & accessories: galvanized metal lath or paper‑backed lath, control/expansion joints, corner and casing beads, fasteners to framing per spec.
• Cement plaster: scratch coat, brown coat, and finish coat with controlled cure; textures from sand float to lace, dash, Santa Barbara, or smooth trowel.
• Acrylic & finishes: acrylic color coats over brown or base; fog coats; elastomeric coatings where specified for hairline crack bridging.
• Repairs & re‑stucco: crack routing and mesh‑reinforced patches, delamination fixes, texture blending, bonding agents, and full restucco over stabilized substrates.
• Sealants & edges: backer rod and sealant at joints and penetrations; clean returns at windows, doors, lights, and hose bibs.

Assemblies & Materials

• Hard‑coat stucco: traditional three‑coat cement plaster for durability and vapor permeability.
• Acrylic finishes: factory‑tinted, UV‑stable coats with consistent color and texture options.
• EIFS (synthetic): base coat with mesh over EPS, acrylic finish; repairs and drainage details handled per system specs.
• Accessories: galvanized or PVC beads and screeds, pre‑manufactured control joints, and corrosion‑resistant fasteners.

Details, Weather & Curing

• Install in suitable conditions (typically 40–90°F, no driving rain); wind and sun exposure moderated to prevent rapid drying.
• Scratch and brown coats kept moist for proper hydration; finish coats allowed to cure per product guidance.
• Clearances maintained above grade and hardscape; terminations detailed to shed water and vent at the base.

Repairs & Matching

• Cracks evaluated for movement; routed and reinforced with mesh‑modified base where needed.
• Texture matches tested on sample panels; color blending planned (spot match, fog coat, or full elevation as aging dictates).
• Efflorescence and staining treated before recoating; incompatible paints or sealers identified and addressed.

Sequencing & Coordination

• Follows window install and roof flashing; integrates with WRB at openings and penetrations.
• Coordinates with electricians, plumbers, and HVAC for sleeves and light boxes before lath.
• Gutters and downspouts set after fascia/soffit; final coats scheduled within good weather windows.

Quality Markers

• Straight beads and joints; consistent texture with no cold joints visible on the elevation.
• Properly lapped WRB and flashing; weep screeds clear and unobstructed.
• Finish coat uniform in color and sheen; sealant joints sized and tooled cleanly.

Safety & Compliance

• Scaffold and fall protection used; mixing and cutting done with silica‑aware dust control.
• Corrosion‑resistant materials specified in coastal or high‑exposure zones.
• Installations meet local codes and manufacturer guidelines for warranty eligibility.

Care & Maintenance

• Annual rinse to remove dust and mildew; avoid high‑pressure washing that can damage the finish.
• Sealant joints and flashings inspected and renewed as needed; vegetation kept off the facade.
• Recoat cycles planned by exposure: fog coat or acrylic refresh as color weathers over time.
