Apply Protective Wood Top Coat

What happens in this clip

After the stain has completely dried, apply a durable wood top coat (sealer) designed for floors or stairs. This will protect the stained wood from wear and tear. The video creator used a regular brush for application. Ensure to follow the manufacturer's instructions for application and drying times. This step is critical for the longevity of your stained stairs. The creator notes that stairs in high-traffic areas will need to be unused for approximately two days after the top coat is applied to ensure proper curing.

Goal: Protect the stained stair treads from damage and wear.

About the full video

This project details the step-by-step process of transforming carpeted stairs into stained wooden stairs. It covers the removal of old carpet, replacement of damaged treads, preparation of the wood surfaces, application of an oil-based stain and a protective top coat, and finishing with painted risers and caulking for a clean, modern look.

Step 11 of 11: Apply Finish (Stain and Sealant)

If staining, apply the stain evenly with a brush or cloth, following the wood grain. Wipe off excess stain as per manufacturer instructions. Allow the stain to dry completely. Once dry, apply the first coat of sealant (e.g., polyurethane). Allow it to dry thoroughly, then lightly sand with very fine-grit sandpaper (320 grit or higher) and wipe clean. Apply subsequent coats of sealant, repeating the light sanding and cleaning process between each coat for optimal smoothness and durability. Typically, 2-3 coats are recommended for staircases.
