What happens in this clip
Once the stain is completely dry, prepare to apply the topcoat. The video recommends Minwax Polycrylic Crystal Clear Topcoat in a satin finish. Before application, it's extremely important to thoroughly stir the polycrylic, as it contains a flattening agent that settles at the bottom, and improper mixing will prevent you from achieving the desired satin finish. Use a high-quality brush, such as a Wooster Gold Edge 2.5" Firm brush, to apply the topcoat. For interior decorative products, one coat may suffice, but for furniture or items requiring more durability, apply multiple coats. The polycrylic dries quickly, typically within a couple of hours to the touch. After the topcoat has fully dried, gently rub the surface with a crumpled paper bag. This step helps to smooth out any lingering texture and provides an even smoother finish.
Goal: Protect the stained wood and achieve a smooth, durable final finish.

About the full video
This project provides a concise, step-by-step guide on how to properly stain and finish pine wood, from initial wood preparation (sanding and filling imperfections) through applying pre-stain, stain, and a protective topcoat, focusing on achieving a smooth, even, and durable finish.
Step 5 of 5: Apply Protective Topcoat
Once the final coat of paint or gel stain is completely dry, apply one to three thin coats of a clear protective topcoat, such as polyurethane or a polycrylic finish. Use a high-quality synthetic bristle brush for application. Allow each coat to dry thoroughly between applications, and allow the final coat to cure for the time recommended by the manufacturer before use.

Stair Banister Refinishing
This project outlines how to paint or gel stain a stair banister without complete removal of the existing finish. It involves cleaning, light sanding, applying a bonding primer (if painting), then applying paint or gel stain, and finally, a protective topcoat. The process aims to refresh the banister's appearance while minimizing labor-intensive stripping.
