Exploring Color Measurement Methods for Fiber Cement Siding

Posted on February 22, 2018

Fiber cement siding—a sturdy combination of wood pulp, fly ash, portland cement, and water—was first introduced in the construction industry just 25 years ago.1 Since then, it’s become one of the most popular materials that architects use for their projects. Almost 15 percent of all new homes have fiber cement siding, in part because this material is so durable and versatile. Although this material can be made to look just like brick, stone, or wood siding, it is actually far stronger than wood or vinyl materials, and less expensive to make than brick or stone. Quality fiber cement siding is fire resistant, termite-proof, rot-proof, and can withstand extreme weather conditions like heavy rain, strong winds or fluctuations in temperature.

But in order to achieve both the durability and beauty of fiber cement siding, manufacturers have to use appropriate color measurement methods at different points in the manufacturing process. Siding color is often the first thing that visitors notice when they look at a house, which is why it’s so important to test for color accuracy before you sell your products to customers. Even subtle inconsistencies in color could make fiber cement siding appear cheaply-made or weather-worn, and will negatively impact the overall appearance of the house. By using spectrophotometric color measurement during manufacturing, you can ensure that every piece of fiber cement siding meets your exacting standards and that your final product will appear beautifully-crafted.

Why Color Consistency Matters

Fiber cement manufacturers have two choices when they craft their materials: they can either paint the final products themselves or sell their customers the unpainted, unstained siding material.2 Regardless of which option you choose, you need to have accurate color measurement methods in place.

Unpainted fiber cement siding is usually light grey in color. If you offer your customers an unpainted, unstained product, you have to ensure that your products are the same standard shade of grey from batch-to-batch. That’s because your customers need a consistent base on which they can apply their final paint or stain color of choice. If the color of your unpainted siding varies batch-by-batch from light grey to dark grey, then the final coat of paint that your customers apply may appear darker or lighter than expected. To ensure that your customers can create the look they want, they must have a reliable blank slate.

Color consistency is also essential if you offer your customers pre-painted, installation-ready products. You have to ensure that every panel is the same color, as even small variations in paint or stain color could make the final siding project appear less aesthetically pleasing. Using a spectrophotometer, you can attain accurate color measurements for every product you make, whether it’s painted or unpainted.
