A Buying Guide to Polyurethane Spray Guns

A polyurethane sprayer has to incorporate grace with grunt. It must have the ability to go slowly but steadily to achieve that protective, glossy sheen. These magical spray guns can reawaken tired wooden projects with just the pull of a trigger.

Things to look out for in this type of spray gun include:

  • Adjustable volume output.
  • Suitably sized nozzle.
  • Portability.
  • Whether it can handle large or small tasks.

Why Use Polyurethane Coatings?

This magical coating will bring finesse to all wood-based items that you have around your home — both inside and out. It also provides a level of protection from accidental scrapes and knocks, as well as the elements. There are a variety of polys for both interior and exterior use available.

Whether you go for an oil or water-based version depends on which type of finish you desire. If you’re after rich amber tones, an oil-based poly is the best choice. Or maybe you want to seal an item or add a protective coat while retaining the wood’s original color, in which case a water-based coating is best.

Without any impact on the durability, you also have the option of satin, semi-gloss, or gloss coatings. While in essence, they all operate under the same principle, it’s worth bearing in mind that if you decide to go for gloss polyurethane, it is more prone to highlight any imperfection in the wood.

How To Choose the Best Polyurethane Sprayer

Polyurethane is a somewhat finicky substance to spray and it has a reputation for being difficult to use. But if you select the best tool for the job, this is simply not true. To remove some of the dread associated with this coating, let’s go through all the critical features that should be included in the best spray gun for polyurethane.
ease of use

HVLP Technology

A great benefit of spraying polyurethane with HVLP machines is that these not only offer a finely atomized finish when working with oil-based polyurethane, but they also help keep costs down and wastage to a minimum as there’s typically less overspray.

HVLP sprayers also tend to suit smaller tasks and are usually a great deal more portable than their airless cousin.

However, you may find that spraying water based polyurethane with HVLP machines doesn’t quite give the results you were hoping for. That’s because water-based versions simply don’t atomize as well as other coatings, for example, lacquer.

true rms

Airless

As I mentioned above, you’re better off spraying water based polyurethane with an airless sprayer — especially if you’re tackling a big project. Water-based coating is more affected by temperature and tends to increase in viscosity the cooler it gets — a whole 10 percent for every 10-degree drop!

When you decide to start spraying polyurethane with an airless sprayer, make sure that the volume output is variable for the best results.

accuracy

Nozzle Size

Similarly to solid stain, polyurethane is classed as a medium viscosity coating. Therefore, a tip size of between 0.013 and 0.015 inches will usually work best.

If your chosen spray gun maker measures tips in other units (some manufacturers tend to incorporate their own jargon into this already confusing field) check the spray gun’s user guide or the company website for recommendations.

Speed Adjustment Button Icon

Variable Output Settings

The key to a glass-like finish is to go slowly and apply many layers, waiting for each to thoroughly dry in between. If you plan to spray polyurethane with an HVLP sprayer, look out at a two-stage turbine at a minimum.

As airless sprayers operate slightly differently, you want to make sure that there is some level of speed adjustability.

Versatility icon

Sprayer Style

Wood-based projects, where polyurethane is an advantage, can vary greatly from boat decks to indoor tables and everything in between. Hence a sprayer that is easy to move is beneficial.

Polyurethane guns are typically available in a multitude of designs, from compact handheld devices to portable floor-based units. The reach of a handheld spray gun is generally limited by the length of your extension cable. Many sprayers have a separate motor housing with in-built storage, which keeps everything together in one place when you need to transport the unit.

How To Use a Polyurethane Sprayer

Thanks to all the horror stories online, the thought of using a polyurethane sprayer can leave even the most experienced home-improver feeling dread.

To simplify the process, I’ve compiled some helpful info. Below I’ll cover how to use these machines, thin polyurethanes, and cover up old polyurethane finishes with a primer — a skill you might need as wood fashions are prone to change in the blink of an eye!

How To Spray Kitchen Cabinets with Primer: A Step by Step Guide

What You Will Need to Follow This Tutorial

Gather everything together before you start to maximize your uptime.

  • Polyurethane spray gun.
  • Interior or exterior polyurethane coating — depending on your project.
  • Stain (if desired)
  • Suitably sized nozzle.
  • Spray tent.
  • Sandpaper.
  • Floor cloths.
  • Cleaning cloths.
  • Shop vacuum.
  • Water.
  • Coveralls or old clothes.
  • Personal protective gear such as a mask, respirator, goggles, and sprayhood.

Step 1: Preparing Your Furniture and Workspace

  1. Lay down your floor cloth.
  2. Start by preparing your furniture item. You need to remove any undesirable marks and fill in other holes and gaps that you don’t want to appear in the final finish. Once you have finished sanding, wipe it down to remove all the residue.
  3. It is imperative that you apply polyurethane in a dust-free environment since any airborne particles can affect your final finish. A good way to provide this protection is to use a spray tent, which will also act as a barrier and protect the surrounding area.
  4. Put on any personal protective gear that you’re using.
  5. Set up your sprayer following the manufacturer’s guidelines. Now is also a good time to dilute the coating, if required.

For further information on how to do this, see the section below.

Step 2: Start Layering

  1. Check you’ve installed the correctly sized nozzle and adjust the volume output dial. The individual sprayer manual should have a chart showing the optimum settings for polyurethanes. As a general rule, you want the pressure to be enough to leave a thin even layer with each pass. Not so much that paint pools are formed and you end up with an uneven surface.

    Try and practice on a piece of cardboard before you start to ensure that the gun’s settings are correct.

  2. If using a stain, now is the time to apply it. Leave it to dry completely.
  3. Now the fun starts! Make like a Jedi Knight with a lightsaber and start spraying your project — sound effects optional. Keep the sprayer around 10 to 12 inches away from the surface and spray in long continuous sweeps. Try to avoid stopping mid-stroke as this will lead to an uneven pattern, which is tricky to correct later.

    If you are not using a stain, treat this first layer as your basecoat.

  4. Once you have coated your piece entirely, step away from the sprayer and allow it to dry thoroughly. For drying time, refer to the paint manufacturer’s instructions.
  5. After the first coat has dried, sand lightly with 220 grit sandpaper. This is not to remove the previous layer but to create a slightly porous effect so that the next coat adheres properly. Once you’ve sanded your item, use a vacuum to remove the dust.
  6. Repeat step two. Depending on how many coats are recommended, you may have to repeat steps three and four too before you’re done.

Step 3: Finishing Up

  1. Once you have applied your final coat, allow your piece to dry completely before touching it.
  2. Thoroughly wash your sprayer and allow it to dry before storing it.
  3. When your item has dried, move to its final home. Then disassemble the spray tent and tidy up any floor cloths that were used.

How To Thin Polyurethane for a Paint Sprayer

Since polyurethane will not stick to itself, it is a good idea to either stain your piece before applying this coating or use a base layer.

What You Will Need

  • Polyurethane paint.
  • Water (if using water-based poly)
  • Paint thinner (if using the oil-based version).
  • Mixing container.
  • Plastic stir stick.
  • Paint measuring cup.
How To Mix a Base Coat

Mix one part of the paint thinner with two parts polyurethane. If you’re using a water-based poly, use water as the dilution fluid.

How to Prepare Additional Coats

For additional coats after the base layer or stain, measure out your desired quantity of polyurethane, calculate what five percent of this volume is. Then measure out the calculated five percent volume of thinner and mix.

For example:

If you want one quart (32-ounces) total volume, measure 1.5 ounces of thinner and mix with 30 ounces of polyurethane.

How To Prime Polyurethane Wood Finishes

Wood fashions change almost as often as my wife changes her mind, which feels like five times a day! For this very reason, you may want to update your beautiful polyurethane finish to another coating. However, as I have previously mentioned poly coatings don’t play well with others so a little preparation is required first.

What You Will Need

  • Trisodium phosphate solution.
  • Cotton cloth.
  • Sanding block, sanding sponge, or power rotary tool.
  • Lower grit sandpaper.
  • Tack cloth.

Process

  1. Add some trisodium phosphate solution to a cotton cloth until it’s just slightly damp, then use this to remove all the grime, grease, and dirt from your item. You may have to scrub fairly hard to remove any stubborn stains. Allow the wood to dry before step two.
  2. Using the power rotary tool or sanding block, remove enough layers until the glossy finish is no longer apparent and the surface is smooth.
  3. If you need a rougher surface or the poly is particularly thick, you can use lower-grade sandpaper.
  4. Grab the tack cloth and wipe away the sanding residue and dust.

You’re now set to start painting your piece with your preferred medium.

Polyurethane Sprayer FAQs

Q: What Is the Best Sprayer for Polyurethane?

In my opinion, the best sprayer for polyurethane is the Wagner Control Painter. Incorporating HVLP technology and Wagner’s iSpray fluid nozzle, it handles medium to large surface areas with ease.

Q: Can You Spray Polyurethane With an HVLP Gun?

Yes, spraying polyurethane with an HVLP device is possible, provided you use the right size tip and have a machine with enough power for this viscous coating. Plus, HVLP technology offers advantages over an airless machine, such as reduced overspray and less wastage.

Q: Can You Dry Polyurethane in the Sun?

In theory, heat speeds up drying times, however, the UV rays from the sun could cause irreparable damage to the finish. Furthermore, you risk dust particles landing in the coating, which would ruin the high-gloss sheen, and put all your hard work to waste.

Q: Is Polyurethane Water Resistant?

Yes, while polyurethane will not completely waterproof an item, it does provide a level of resistance.

Q: Is One Coat of Polyurethane Enough?

As a general rule, you need a minimum of two coats to achieve a perfect overlay. Some manufacturers even recommend three.

Q: How Long Does Spray Polyurethane Take To Dry?

After around two hours, polyurethane should be dry to the touch. This being said, I would recommend that you leave the polyurethane to dry overnight before moving or using the item.
