Putting a topcoat or sealer is the most complex task when painting a wooden surface. A slight mistake in such a task can ruin the look of a newly painted surface. That is why professionals suggest using sprayers for painting or varnishing wood as sprayers have fewer possibilities of making errors than brushes or rollers. But do all the sprayers have the ability to spray varnish liquids like polyurethane? Varnishes or polyurethanes are way thinner than usual paint products. Their dry time is also a bit different. For these reasons, you have no other option than buying the best spray gun for polyurethane here. 

Using a normal spray gun for finishes can give you a worse result than using rollers or brushes. This means, both your money and effort can go in vain as sprayers are a bit costly tool. Now, you can ask me what makes a spray gun capable of spraying complex things like polyurethane. If this is your question, then my today's article is the answer to that question. I am showing some top-class spray guns along with a simple guideline to get a sprayer, especially for polyurethanes.

Generally, a sprayer needs to have smaller tips and balanced pressure creating construction. Together, they can create and release very small particles of polyurethane while spraying, which mainly creates a firm coat on the surface. Apart, the sprayer needs to maintain the volume pretty well as topcoats on woods should be thinner. So, polyurethane spraying guns are those which powerfully releases the liquid to create a firm and smooth coat, but keeps the coat thinner and smoother.

Reviews of the Polyurethane Spray Guns

​Here are my top ten picks that I have tested in painting wooden stuff. I have also given priority to experts' opinions while making this list and reviewing the products.

​What to Concern Before Buying a Polyurethane Sprayer?

The considerations before buying a spray gun are as important as doing some warm-ups before playing a game. So, here are some common facts that you should not forget if you are looking for new paint sprayer.

Price

For me, anything above 50 dollars is not eligible. You can easily find a quality sprayer within 25 bucks. A top-class sprayer for finishing can rarely have a price of more than 45 dollars.

Type of Sprayer

When you need to spray a thin and smooth coating, HVLP sprayers are the most common and reliable options. Even I can't trust anything more than HVLP guns. But still, you can get some model which can perform better than HVLP guns in some ways.

Type of Work

​Lots of things depend on the type of work you are going to do. Only a few sprayers are vital in both indoor and outdoor paint jobs. Apart from that, you should also keep in mind the size and difficulty of the task before picking any gun. It helps to clarify your confusion in many ways.

​How to Buy the Best Spray Gun for Polyurethane

The buying guide for the polyurethane paint sprayers is almost like other paint sprayers. But there are some exceptions between other guns and guns specially made of spraying polyurethane and varnish. Our buying guide helps you to know what you should judge that can make you reach the best spray gun for wood finishing quickly.

Power

One of the vital aspects before opting for a spray gun is its spraying efficiency. Spray guns with high power efficiency recruit superior finishing that is long-lasting enough. The power range comes with the spray guns are 500 watts to 800 watts. With high power efficiency, it covers smooth finishing to uneven surfaces too.

Material
