Sample boards are a great tool for reducing headaches when working with clients on texture options. They allow clients to visualize different textures on a small scale before committing to a larger project. It's important to have clients sign off on their chosen texture to ensure clarity and avoid misunderstandings. Using sample boards with larger sizes provides a better representation of how the texture will look on a wall. Different textures like stomp knockdown, skip trowel, faux plaster, swirl, and random plaster can be demonstrated on sample boards to showcase various options to clients. Keeping the application simple and consistent on sample boards will make it easier to replicate on a larger scale. Overall, sample boards are a practical and effective tool for communication and decision-making in the drywall industry.
