Abaco Plastering & Stucco's applications are always completed with high standards and high quality products. A lath of an asphalt-infused paper with furred chicken wire is laid down over a weather-resistant barrier. Next comes the scratch coat, which is a layer of field-mixed Portland cement, sand, lime, and water with a series of horizontal lines scratched into it. Then comes the brown coat. This layer is applied with a darby, or long trowel, to make sure the cement is applied evenly.
