How to apply varnish without brush marks

What is a varnish brush

Bristles

Soft hair bristles work best with varnish. They can glide smoothly without causing any bubbling or streaking. If you have a big budget available, look for artificial fiber filaments. These are more durable and are highly recommended because they can work with any varnish. Nylon brushes will give you a good flexibility level. Stiff brushes should be avoided because they often leave marks on the surface. 

Shape and Size

Flat brushes with a broad surface will provide you with the most effective application motion. These brushes are the optimal option for applying varnish. It will help you cover more ground much faster. The improved speed is because, with this brush, you can perform broad and continuous strokes. This motion prevents marks and saves time. A 2” broad brush is the most recommended option. This choice should mainly depend on your personal preference and comfort. 

Durability

Durability is an essential factor because varnish brushes are costly and often cannot be replaced. It would help if you did not paint with the same brush you used to varnish. Mixing the two can lead to contamination and enhanced longevity.

How to apply varnish without brush marks

A simple method to avoid brush marks is to use a very thin coat of varnish. This consistency helps to make brush marks less likely to remain as they dry. The process is much smoother when you use mineral spirits in your varnish. Having a smoother solution works to help the finish to flow out more consistently.

Applying varnish with a rag

Start by using a clean towel or cotton rag that has been folded. Ensure that it is folded with corners so to allow for simple application. Place a corner of the rag into the solution container. Try your best only to use a small amount. Try to make it as even as possible. You want the solution to be wet and enough to cover the surface of your project. Apply the solution moving in line with the wood grain. Continue to wipe the surface with the liquid gently and carefully use overlapping strokes.

How to apply varnish with a cloth

This task should be performed with a clean cotton cloth. Any dirt will cause bubbles and brush strokes to remain on the surface. The key is to use a wiping motion rather than a brushing one. Using circular strokes, wipe the finish gently. Make sure that you are following in the direction of the wood grain. The goal is to keep it level and well coated. Once complete, let it dry overnight. Apply the finish with circular strokes

Applying varnish with a sponge

Place the broad side of your sponge into the varnish. Try to ensure that you collect a level and consistent amount. Once complete, you can use broad and long strokes to apply the varnish. This method will help reduce the varnish you need because of its equal application.

  1. Apply the solution quickly and carefully. 

Using long strokes will save you precious time. Working fast is essential because the solution will dry immediately when you begin working. 

  1. Left to right motions 

Make sure you build on your work as you go. Ensure each motion helps you to overlap each stroke slightly. This method will help to prevent any visible brush marks.

  1. Avoid going back for areas that you have done. 

Do not try to be a perfectionist and fix already applied varnish further. Doing such an action will risk dragging partially dry resin into wet. This method will end up giving your wood a dry cloudy color. If you wish to go back, allow the wood to dry completely. Three thin coats will work better than one thick one.
