The Difference Between Three-Coat And One-Coat Stucco Processes

The Difference Between Three-Coat And One-Coat Stucco Processes

Stucco is a lovely alternative for a textured finish on your house or business structure. You can use a variety of textures as a finish to give your building a unique appearance or to make it seamlessly blend in with the surroundings. However, there is more to the stucco installation process than initially appears.


Stucco is much more than just the textured finish we see on exterior walls. At least one further layer is beneath that texture. This “primer” layer increases durability and provides a strong foundation for the stucco, extending its lifespan.


Processes used to create stucco come in two varieties. The first is known as three-coat stucco, whereas the second is known as one-coat stucco. The differences between a three-coat and a one-coat stucco procedure are discussed in length here, along with which method would be ideal for you in Wayne.


3-layer stucco


Three coats of stucco were traditionally used when applying it. Three layers are involved, with a textured finish on the outer layer.


Chicken wire and paper with asphalt infusion make up the bottom layer, which is dispersed across a weatherproof barrier. Before a brown coat is placed with a long trowel, the area is first covered with a “scratch coat” made of Portland cement, lime, sand, and water. The final finish can then be applied to the texture of your choice.


Given that it is twice as thick as one-coat stucco, this has the significant advantage of being stronger and more resilient. This comes at a price, though, as this method is more expensive and takes much longer to finish than the one-coat stucco process.

One coat stucco


One-coat stucco is actually two separate layers of stucco, hence the label “one-coat” is misleading. The procedure was revised to include a second top coat finish since the original process entailed blending a colored finish coat into the initial blend, which produced an uneven and inconsistent outcome.


Using this method, the scratch coat and the brown coat are combined together to create a single mixture. As a result, a task can be finished in a few days or even a few hours in some cases. Since it is less expensive and requires less work than three-layer stucco, its popularity has increased recently.


The drawback of this method is that it results in a thinner product that is more vulnerable to harm. The durability of three-coat stucco is superior.
