Introduction Stucco at window sills is the way the exterior plaster and the window flashing work together to shed water away from the opening; a proper setup keeps water off the wall below and prevents staining. In practice that means installing a flashinged sill, a drip edge or kerf, and end dams where the stucco […]

Introduction Galvanic corrosion is a common issue that affects stucco accessories, particularly metal beads and trims. This process causes rust stains on your otherwise pristine exterior, marring its appearance and potentially leading to more serious damage over time. The good news? Understanding the cause of this problem can help you prevent it from happening again.

Rust Stains at Stucco Beads: Start With the Source Orange or brown streaks at a stucco bead, casing bead, reveal, weep screed, or fastener do not prove galvanic corrosion. Ordinary corrosion of exposed or cut steel, water leaking from flashing, and rust bleeding from concealed lath can produce similar stains. Treat galvanic corrosion as a

Introduction Painting stucco with maximum breathability means choosing and applying coatings that let moisture vapor move through the wall rather than trapping it behind the finish. In practice that means picking a paint or coating labeled for masonry/stucco breathability and preparing the surface so the coating can adhere and perform; check product labels and manufacturer

Introduction Installing stucco window sills with drip edges and end dams is a crucial step in waterproofing your home’s exterior. But how long does this process take? Let’s break down the timeline so you can plan your DIY project effectively. Whether you’re a seasoned DIYer or a first-timer, understanding the duration of each step will

Introduction A stucco edge beside brick or stone is not one universal detail. The correct termination depends on the stucco system, the wall’s drainage plane, and whether the masonry is full-bed masonry, adhered veneer, framed veneer, a jamb, a roof intersection, or a base-of-wall condition. A visible joint can look simple while the flashing and

Introduction A parapet leak is rarely solved by filling the nearest crack. Water may enter at a coping joint, a roof-membrane-to-wall transition, a wall crack, a penetration, a window intersection, or—when dampness occurs without rain—from condensation. A durable repair restores the water-shedding layers in the right order: roof flashing and coping first, then the wall

Introduction Stucco penetrations for electrical conduit are the sleeve and sealing details that keep water out where the conduit passes through the stucco wall. In practice that means a rigid sleeve or short piece of conduit, a backing, and a proper sealant or flashing so water sheds away from the opening; check product labels and

Introduction Stucco around roof-to-wall kickout flashing is the detail where the siding meets the roof and the flashing diverts water away from the wall; fixing it means making sure the flashing, substrate, and stucco meet cleanly so water can’t get behind the finish. This is a hands-on job that usually involves removing a bit of

Introduction Removing loose stucco safely means knocking out and replacing only the failing material while keeping dust off you and your house and protecting the weather-resistive barrier behind it. Start by finding the delaminated areas with a tap test and visual checks, then plan cuts and containment before you touch the wall. Use dust control
