The Comprehensive Guide to Stucco Fasteners

In the realm of construction and stucco application, the choice of fasteners plays a pivotal role. My expertise in stucco application and construction spans over a decade, providing me with ample experience to guide you through various fastener options. This article, enriched with references and a focus on accuracy, aims to be a definitive guide for homeowners and DIY enthusiasts.  Fasteners for Wooden Substrates Staples for Stucco Lath   Staples are the preferred method for attaching wire to paper or foam in wooden substrates. A specialized staple gun is used for this purpose, capable of firing wide crown staples. For a three-coat stucco process, 1 1/4″ staples are standard, while 2″ staples are used for a one-coat system. Ensure at least 3/4″ penetration into a stud, adjusting for thicker sheers.  Nails for Stucco Lath Two types of nails are predominant:

• 4 Penny Nails: Used in three-coat stucco, these galvanized nails are partially driven and then bent over the wire for securement. 
• Roofing Nails: Preferred for one-coat applications, they simultaneously hold down foam and wire. 

 

Self-Furring Nails

These nails, which create a gap for cement to key in behind the wire, have become less common due to the advent of pre-furred wire and staples.  Fasteners for Masonry/Concrete Substrates Masonry Nails   Stronger and thicker, these nails are designed to penetrate hard surfaces like concrete and cinder blocks.  Ramset Nails   Shot into concrete using a special tool, these nails are ideal for attaching lath to concrete surfaces. A variety of Ramset guns are available, catering to different budgets and user-friendliness.  Concrete Screws   These are used when nails are impractical, providing secure contact on masonry surfaces. Some varieties may require pre-drilling.  Fasteners for Metal Projects   In buildings with metal studs, typically in commercial construction, self-tapping galvanized screws with wider heads are used to attach wire lath.  Fasteners for Existing Stucco Light Duty Fasteners   Outdoor hooks, available in various sizes and colors, are suitable for weights ranging from 2 to 5 lbs.  Medium Duty Fasteners   Traditional screws and nails, requiring pre-drilling with a masonry bit, can support approximately 10-20 lbs. Metal hooks are recommended for their durability.  Heavy Duty Fasteners   Lagbolts, larger in diameter and length, are ideal for supporting heavy items like sun canopies.
