Nevertheless, consider the benefits of spray-on or wipe-on polyurethane formulas. Brushing on polyurethane is the best way to cover large areas. However, small surfaces and/or tiny details can be accomplished easier with the use of spray-on and wipe-on pads of polyurethane products.
2) A quality brush
You can go for a synthetic or natural brush with the same success upon application. A foam brush is also welcome. Just make sure you stay away from low-quality brushes because this will end up causing ugly strokes on the wood surface.
3) Sandpaper/ Sander
You will need to utilize sandpaper continuously throughout the process of polyurethane application. You need both fine grits, as well as coarse-grit sandpaper.

Step By Step Tutorial On Applying Polyurethane To Wood Surfaces
Step 1: Prep the wood and start applying polyurethane with controlled, long strokes.

Use coarse-grit sandpaper to clean the wood precisely before adding the first layer of polyurethane. It is best to opt for coarse-grit sandpaper at the start. Remove any traces of dirt, grime, sand or tiny particles left behind before you begin coating the wood with polyurethane.
Before you even dip the brush in polyurethane, it’s important to follow the manufacturer’s instructions indicating the best way to mix the concoction before getting started. Next, dip the brush and remove the excess quantity. Proceed with long strokes which follow the grain of the wood. Do not apply too much pressure.
Step 2: Let the coat of polyurethane dry out and sand once again.

Water based and oil based polyurethane require a different amount of time to dry out. Thus, it is essential that you stick to the instructions available on the label of the polyurethane variety you have chosen.

Once the first coat has dried out completely, you can proceed with sanding the surface of the wood. Sanding the wood is a continuous practice throughout the entire application of polyurethane. It helps to avoid rough patches and makes up for a smooth, even surface.
Ultimately, you will want to keep repeating the process of layering a coat of polyurethane and sanding the surface of the wood until you achieve the results you are aiming for. You will need at least 2 basic coats of polyurethane. The more you keep layering precisely, the better finish and durability you can enjoy at the end.
