Traditional stucco is a proven, cement-based cladding that holds up when it is installed as a true three-coat system with proper drainage and control joints. Superior Stucco St. Louis has served St. Louis since 2018, installing and repairing traditional stucco on homes and commercial buildings with clean details and durable finishes.
Good traditional stucco starts with prep, straight planes, and a solid base. We protect landscaping, set up staging, and verify framing, sheathing, and flashing at windows, doors, and roof-to-wall tie-ins before any plaster work begins. For new installation, we install a WRB (weather-resistive barrier), weep screed at the base, casing beads at terminations, expansion and control joints where needed, then self-fur 2.5 lb galvanized metal lath fastened to studs, followed by a scratch coat and brown coat mixed to the right cement-lime-sand ratios and applied to uniform thickness, typically about 3/8 inch each coat for a true three-coat assembly.
St. Louis weather swings from humid summers to freeze-thaw winters, so traditional stucco needs smart water management and curing. We pay close attention to kick-out flashing, drip edges, and positive slopes so bulk water sheds fast, then we fog-cure and protect fresh plaster to reduce shrinkage cracking and strength loss. For repairs, we cut back to sound material, patch with compatible base coats, tie into existing lath when possible, and blend texture so the repair does not telegraph through the finish. Finish options include fine sand float, lace, skip trowel, dash, and smooth trowel (when appropriate), plus acrylic or elastomeric coatings when the wall needs additional water resistance and color uniformity.
Customers choose us because we install traditional stucco the way it is meant to be built, not as a thin decorative skim over questionable surfaces. You get clear scope, straightforward recommendations on whether to patch, recoat, or remove and replace, and a crew that respects jobsite cleanliness and adjacent materials like brick, limestone, EIFS trim, and painted wood. We are licensed and insured, and we bring the right equipment for consistent results, including mortar mixers, hawk and trowel sets, stucco pumps when the job calls for it, and moisture meters for diagnosing leak-driven damage before we cover it up.
At the end of the job, we walk the walls with you and document what was repaired or installed, where joints land, and how drainage details were handled at the base and around openings. You receive a written estimate up front, a defined finish sample or mockup when needed, and practical maintenance guidance, including recommended repaint cycles, sealant checks at penetrations, and when to address hairline cracks versus structural movement. We clean up daily and leave the site broom-clean, with protected windows and fixtures free of overspray or stucco residue. If you are comparing bids, we will explain thickness, coat count, lath type, joint layout, and curing steps so you can make an apples-to-apples decision.

Yes. We provide a free written estimate that outlines the scope, materials, and the recommended repair or replacement approach.
Yes. We repair and install traditional cement stucco and EIFS systems, using compatible base coats, mesh, accessories, and finish coats for the existing assembly.
Temperature and moisture matter for curing and adhesion. We schedule work around conditions and use appropriate protection so base coats and finishes cure correctly and avoid washout or freezing.
Frequent causes include missing or incorrect flashings, poor WRB laps, buried weep screeds, inadequate lath fastening, lack of control joints, and sealant failure around penetrations and openings.
Small patches may take 1-2 days plus cure time, while larger remediation or full replacements take longer due to demo, substrate repairs, multiple coats, and drying time between steps.
Traditional stucco is a cement-based exterior plaster system built in layers to create a durable, breathable cladding. When installed correctly with a drainage plane, metal lath, proper jointing, and controlled curing, it performs well on both residential and commercial buildings. Superior Stucco St. Louis focuses on true three-coat work and compatible repairs that protect the wall assembly instead of just hiding symptoms.
Traditional stucco (cement, sand, lime, and water) is different from EIFS and different from a one-coat synthetic system. It relies on a layered approach: a scratch coat keyed into metal lath, a brown coat to build plane and strength, and a finish coat for texture and appearance. The details around windows, doors, decks, and roof intersections matter as much as the plaster itself, because bulk water is the main cause of staining, cracking, and substrate deterioration. That is why our installations emphasize WRB layering, proper laps, sealed penetrations, and drainage at the base with a weep screed.
For repairs, we start by identifying why the stucco failed, impact damage, movement, poor curing, or moisture intrusion. We remove loose material, address rusted lath or deteriorated sheathing when present, then patch with compatible base coats so hardness and permeability match the surrounding wall. Texture and color blending are handled carefully, whether the finish is sand float, lace, or a heavier dash, and we will recommend breathable coatings when uniform color and added water resistance are needed.
