Acrylic Finish vs Stucco Finish Acrylic Finish vs Stucco Finish

Acrylic stucco finishes are used as the last coating for concrete bases, with acrylic being introduced much later than stucco. The latter has been used for several centuries while the former has only been around for several decades. Although both are great finishing materials, there are several differences between both, and knowing these will help homeowners or contractors decide on which to use best as a finishing material. Here are some common differences between the finishes.

Composition and Manufacture

Since stucco has been traditionally employed in construction projects, it makes use of naturally occurring materials. Stucco is composed of sand, lime and cement, while acrylic is synthetic. This spells the difference, suggesting which one is a more environmentally friendly finish to use. Since homeowners have the last decision when it comes to finishing material, it is up to the contractor to explain the difference between the two.

Color Options

Since acrylic finishes are synthetic, they come in many different colors suited for any type of background. The color is also consistent and quite uniform. It can be made into lighter shades as well as into darker ones. Since stucco only holds a few pigments, color is not that flexible. Although there are colored stucco finishes, homeowners will not find a large variety of them. This is the reason why those who prefer to have colorful homes use acrylic finishes as an alternative to stucco.

 Repels or Absorbs Water

Stucco will absorb moisture and become darker in color when wet. However, acrylic finishes retain the same color even when dampened. Acrylic does not allow moisture to pass through the membrane but will allow vapor nevertheless. Since stucco does not have the same water resistance property as the acrylic finishes, manufacturers provide sealers that can be applied to stucco.

Application and Drying

There is a big difference when it comes to the application and drying processes of both acrylic and stucco finishes. Acrylic dries starting from the outside, meaning that it needs to be applied when external conditions permit. It is recommended that the finish is never applied when the temperature is below 40 degrees F. If the weather is too cold, the acrylic finish will not dry as fast as it should. However, since stucco cures in order to harden, it can be applied anytime, regardless of the temperature being low or high.

Maintenance and Durability

Stucco and acrylic do not require high maintenance, and they can be both painted with any color as well. Regarding durability, stucco has been tried and tested, and it does prove to be very durable. Since acrylic is a relatively new material, it is not easy to say whether it can withstand the test of time for many decades, but it does prove to be durable for the time being.

When deciding on which type of finish to use, make sure you take note of the above information for guidance. Although both have pros and cons, the best thing to do is to ensure a proper application to attain durability.
