What is recommended for sealing the edges of a hardwood floor?

Sealing the edges of a hardwood floor is essential for protecting the wood from moisture and dirt, as well as providing a finished appearance. Wood putty is specifically designed for this purpose because it adheres well to the wood fibers and can blend in with the color and finish of the hardwood.

Wood putty is easy to apply and can fill small gaps and imperfections, ensuring that the edges are properly sealed. It is also paintable and stainable, allowing for seamless integration with the surrounding wood, enhancing the overall aesthetic of the flooring.

In contrast, silicone sealants are typically used for areas where flexibility is needed or where water resistance is a priority, but they may not provide the best finish for hardwood flooring. Construction adhesives are more suitable for adhering flooring materials but not for edge sealing, as they can create an uneven surface. Nail fillers are primarily used to cover the holes left by nails, which is different from sealing the edges of the entire floor. Therefore, wood putty is the recommended choice for effectively sealing the edges of a hardwood floor.
