There are so many different types of fasteners used in lathing. Stucco can be applied to virtually anything, so different substrates require different fasteners. Let’s take a look at some of the various types to get a better understanding of the different types and what they are used for.
Fasteners Used For Wooden Substrates:
- Staples – These are the recommended and code enforced method to attaching the wire to the paper or foam. They have a wide crown and come in different lengths to meet the required depth of the specific stucco system you are using.
- Nails – There are two specific types of nails used in the lathing process involving wooden substrates. One is made for the three coat process and tyhe other is intended for the one coat process (aka, two coat stucco).
- 4 Penny Nails – For three coat stucco, galvanized 4 penny nails are the common choice, seeing as how they are the proper length. These are nailed in about three quarters of the way and then bent over the wire to secure the wire.
- Roofing Nails – For one or two coat stucco, roofing nails are a better choice because the head of the nail holds the foam down and the wire at the same time. They come in a variety of lengths, but are typically 1 and 3/8 – 1 and 3/4 of an inch in most stucco applications.
- Self Furring Nails – These have a spacer on the nail that “gaps” the wire off of the wall so that the cement can key in behind the wire. These are not typically used nowadays because the wire is furred.
Fasteners For Masonry Surfaces:
- Nails – There are a couple of different kinds that are used for concrete and masonry surfaces. They are much stronger than the average nail and can take quite a bit of abuse without breaking or bending.
- Masonry Nails – These are stronger than typical nails, they are thicker and hardened in order to penetrate harder surfaces such as concrete and cinder blocks.
- Ramset Nails – These are very strong nails that are shot in using a special tool. It uses gunpowder to shoot the nail into medium to hard surfaces. They can have a washer on them if one is required.
- Screws – These are used when nails cannot be utilized, or when constant pressure is need at all times, like installing weep screed or plaster stop on a hard surface.
- Concrete Screws – These are designed to grab the concrete and provide a secure contact point on any type of masonry surface. Some may require pre-drilling.
