How Do You Seal Shiplap for Backsplash?

Sealing shiplap for a backsplash is an important step in the installation process to protect your walls and maintain the beauty of your space. Shiplap is a popular choice for backsplashes due to its timeless and classic look, but it requires proper sealing to prevent moisture damage and ensure longevity. In this blog post, we will discuss different methods of sealing shiplap for a backsplash and provide tips on how to achieve a professional finish.


Before you begin sealing your shiplap backsplash, it is essential to properly prepare the surface. Start by thoroughly cleaning the shiplap with a mild detergent and water to remove dirt, dust, or grease. Allow the surface to dry completely before proceeding with the sealing process. It is also important to fill any gaps or cracks in the shiplap with caulk to create a seamless finish.

Choosing the Right Sealant

When it comes to sealing shiplap for a backsplash, there are several options to choose from. One popular choice is a polyurethane sealant, which provides a durable and water-resistant finish. Other options include oil-based sealants, which offer excellent protection against moisture and stains, as well as water-based sealants, which are environmentally friendly and easy to clean up.

Applying the Sealant

Once you have chosen the right sealant for your shiplap backsplash, it is time to apply it to the surface. Start by using a brush or roller to apply an even coat of sealant to the shiplap, working in small sections to ensure thorough coverage.

Allow the sealant to dry according to the manufacturer's instructions before applying additional coats if necessary. Following the recommended drying times is essential to prevent the sealant from bubbling or peeling.

Finishing Touches

After applying the sealant, take the time to inspect the shiplap backsplash for any imperfections or areas that may need touch-ups. Use fine-grit sandpaper to smooth out any rough spots or drips in the sealant, and apply additional coats as needed to achieve the desired level of protection. Once the sealant has cured completely, you can install your shiplap backsplash using adhesive or nails, taking care to align the planks evenly for a professional finish.


It is important to perform regular maintenance to maintain the beauty and durability of your sealed shiplap backsplash. Clean the surface with a mild detergent and water as needed to remove dirt and grime, and inspect the sealant for any signs of wear or damage. If necessary, apply a fresh coat of sealant to protect the shiplap from moisture and stains and ensure its longevity.
