Pros and Cons of 3-Coat vs 1-Coat Stucco Systems

Pros and Cons of 3-Coat vs 1-Coat Stucco Systems

In today’s blog we are going to talk about the pros and cons of 3-coat versus 1-coat stucco. In order to compare them, let’s do a quick review of what these different methods are.

Stucco in General

So, first, stucco is a textured interior or exterior finish which has been around in one form or another for thousands of years. Today, stucco is typically made of Portland cement, water, sand, and a calcium compound such as lime or gypsum.

1-Coat

What we call one-coat stucco is stucco applied over some kind of foam board and wire. It is actually more than one coat because there will be a finishing coat added to any kind of stucco.

3-Coat

What we call three-coat stucco starts with a layer of paper covered with wire, then a scratch coat, followed by a “brown” coat. Last there will be a finish coat.

The biggest advantages of 3-coat stucco are that it is much thicker and will last longer. Since it is thicker, it will be a better source of both insulation and fire deterrence. It is also less likely to crack and need repair.

The biggest advantages of 1-coat stucco are that it is faster and cheaper to apply because it is not as many coats and not as thick. So, you would save money in the upfront cost but not necessarily in coast over time. One-coat stucco will not last as long as 3-coat, and it does not confer the advantages of the thicker coat.
