If you want to have a long lasting protection for your wood surface and make it look beautiful in a natural way, then covering it with a polyurethane varnish is an excellent choice.

Polyurethane is among the most durable and toughest clear coatings. Spraying polyurethane can be one of the messiest jobs to accomplish. However, if done the right way, it can bring out the inherent grain and beauty of the wood and protect it for a long time.

You can get a smooth and blemish free finish with polyurethane if you follow the essential steps listed in this guide. Tips presented in this article will help you understand the intricacies of spraying polyurethane varnish and teach you how to do it like a professional.

What is oil based Polyurethane varnish?

Polyurethane is an ultra-resistant varnish formulated so that its microscopic chains of resin molecules will bond tightly with one another as it dries. As a result, polyurethane coat adheres to the surface it is sprayed on and gives a finish that is much more resistant to water, solvents, heat, abrasion, and impacts than any other traditional varnishes.

Oil based polyurethane varnish gives the wood a warm and amber tone. It forms a hard and tough film in few coats. Oil based varnish mixture provides attributes of both ingredients, easier application of oil and protective qualities of varnish. It generally dries slower than other varnishes which mean you have to wait longer between coats.

Preparation work: Tool, Material, and Environment

Before you start spraying job, it’s critical to do some preparation work. It involves setting up the tool, material, surface, and environment.

First of all, your workspace must have enough light and proper ventilation. A dust-free space is essential to achieve a perfect and flawless finish.

Polyurethane has a strong smell and is dangerous to breathe, so work outdoors if possible. If you are working indoors, select an area that is well ventilated and wear a respirator to protect yourself. Work with open windows.  The workspace shouldn’t be too cold or damp as it may affect the dry times of coats. During the drying process, fumes have emitted that need to be dispersed. Having an exhaust fan facing out is a good thing to remove vapors.

You need an HVLP sprayer for application. Our recommendation on that is DeVilbiss 802342 StartingLine HVLP Gravity Spray Gun Kit. This sprayer is fast and creates a fine mist of solvent that settles on a surface to give a smooth finish. With this sprayer, it’s much easier to manage the application as you can change air speed, volume, and pressure. It gives you a charming pattern when you spray against the wood.

And more, you need a portable compressor to make air. Set the pressure at very low at around 10-15 psi and then change accordingly to your desired pattern and thickness.  While preparing the solution, you can use 2 parts of polyurethane to 1 part of mineral spirit for wider coverage without being too thick. A good mix will prevent overspray and avoid dripping.

You can see that step by this video (doing by DarbinNotes)

Prepare the Wood

Any varnish demands a smooth surface to sit properly and look good. Make sure the wood surface is ready to receive a coat by first sanding with medium grit sandpaper in the direction of the grain. Then use a progressively finer grit sandpaper.

For small wood projects, sanding by hand is best. Cut the sheet of sand paper and fold it beneath your fingers. For large, flat surfaces, an electric orbital or palm sander can be used, or you can wrap the sandpaper around a scrap piece of wood for flat surfaces.

After done with sanding, carefully examine the surface. Look closely for any scratches left by coarse-grit sandpaper. Once the wood is blemish free, remove the dust. After sanding, wood is ready for a clear protective finish to be applied.

Apply a wood stain

If you plan to stain the wood surface, this is the stage you have to apply it. Choosing a stain is a matter of personal preference. There are a variety of stain colors that feature traditional wood tones and coordinates with your décor. No matter what type of stain you choose, make sure the surface is dry, clean and free of dust. If you don’t plan to stain the wood, you can skip this step and proceed directly to next.

Build polyurethane finish coating: Tips and Advice

Start and stop spraying at far edge

Start spraying the varnish in an even manner, move across the project at an even pace and cover the entire surfaces. Be ready to apply a coat in a continuous manner. Because if you start and stop spraying, it hard to get an even coverage. Spattering is the problem that occurs when you apply the polyurethane improperly, and it can blemish the surface. To avoid this, start spraying before you reach the edge of the wood and stop when you have gone past the far edge. This way ensures spattering free coverage across the entire surface.

Do not spray in an arc

It’s quite natural to spray in an arc. This spraying type gives varnish buildup in the center and light on the edges.  To avoid this uneven spray coverage, move your full arm over the surface of the wood at the same angle. Do not just swing the sprayer.

Keep parallel spraying

Keep the spray tip parallel to the surface at all times. Move the sprayer at a steady pace while keeping it at an equal distance from the surface. The goal is just to spray enough polyurethane to wet the surface. Apply several thin coats instead of few thick coats which create runs. The surface may look blotchy after the initial coat but will lead to more uniform finish in the end.

Overlap coasting

Overlap the spray about halfway on to the previously sprayed surface in order to achieve a uniform finish in the end. Overlapping ensures the same finish everywhere.

Finishing work

Before applying the final coating, wet sand the surface with fine grit sandpaper. It will give you a smooth surface free of bumps. Wait at least 48 hours before polishing the surface with rubbing compound. Apply the polish onto the surface using a circular motion. After rubbing, let the surface dry and buff with a dry cloth. Here, you have a great looking finish.

How to Use an Air Impact Wrench Right Way

Air impact wrench is the high power tool. It makes high torque use loosing and tightening nuts and bolt. It mainly used for automotive and significant assembly work. Not like a cordless impact wrench what you can do everywhere you want to do and can operate by the battery, the air impact wrench needs an air supply system to work. But using an air impact wrench is easy, and we write down some easy step to use it, even when you are a beginner.

  1. Prepare work

Air impact wrench

You need one an air impact wrench to loosing and tightening works. Including you must have one air supply system. The air supply system is one air compressor what supply air for the impact wrench to work through a soft pipe connecting the air compressor hose to the impact.

You must read the product description of air impact wrench about CFM and pressure value is needed. Choose one a compressor has CFM higher than SCFM of impact wrench is better. A bigger tank of the air compressor keeps the impact wrench works continuously better than the small one.

For instance, You have one Ingersoll-Rand 231C 1/2-Inch Super-Duty Air Impact Wrench with air consumption is 4.2 CFM @90psi. You need to choose a compressor have from 4.5 CFM more.

If you used compressor before, you know it has water inside, what including with the air and go in the air impact wrench when it is working. Keep for the air dry; you need to prepare one water filter and one oil cup set as well. The water filter only allows the dry air pass and keep the water stay in the both, the air after passing the water filter is dry.

How to Pre-Drill Pilot Holes for the wood Screw’s Best Fit

pilot hole for wood screwPilot holes are pre-drilled small holes that are important when driving screws into the wood. This hole is often created to prevent the wood from splitting into two whenever you are driving a screw through it. Another benefit to pre-drilling pilot holes offer is the ease of installation and accuracy of the driving of the screw, especially if you are working with hard as well as dense wood. With pre-drilling pilot holes, you will be able to get the most effective as well as long lasting fastening power from the screws considering that you are able to do the job perfectly and with the correctly sized clearance and holes.

Determine the Location of the Screws and Marking the Right Spot

Before drilling any hole on the wood that you are working on, you have to determine the exact location of where you want to drive the screw. This is an important step to make sure that the screw will fit perfectly into the pilot hole. Using a tape measure or a ruler, you can measure and determine where you need to pre-drill the hole for precise applications. Once you are able to determine the location, you have to mark the spot using a pencil or any other marking pen.

Prepare All Things Needed, Especially the Wood

It is very important to prepare everything before you start working. All materials must be ready before working. Likewise, you may need to make a small indention on the spot where you need to place the pilot holes. Doing this will ensure that your drill bit will travel straight and will not run off to other directions. You can make a small indention using a punch. This is a small and slim tool with a pointed end on one side. To use this tool, you have to align the punch with the marking you created and lightly tap the tool with a hammer.

Selecting the Right Drill Bit Size to Use

When selecting a drill bit, you have to remember to select the bit that is slightly smaller compared to the diameter of the actual screw that you will be using. If you drill a hole with the same size or perhaps larger than the screw, this will not hold. Thus, a smaller hole is necessary as this will the screw threads to grip the material and hold on to it without splitting the wood.

pilot hole screw size

For most hardwoods, the pilot hole must be at least as big as that of the actual screw’s minor diameter. If ever the screw has a deep thread or that the wood that you are working on is very hard, the pilot hole must be another 1/64 inch larger than the minor diameter of the screw. However, for softer types of wood, the pilot hole may be 1/64 inch smaller than the minor diameter of the screw. See more at Wlfuller.com

If you skip pilot holes or drill a too small one, this can create hairline cracks in the wood. Visible cracks are definitely bad. However, smaller cracks can eventually widen and cause the joint to fail in the long run.

The Actual Drilling Process for Pilot Holes

When you are ready to drill the pilot hole, you have to align the tip of the bit with the invention you have made on the wood. With the power drill, you need to adjust its position until you are able to achieve the desired angle for the screw. You have to remember to drill the pilot hole deep enough so it can accommodate the length of the screw. You have to keep a firm grip on the drill to prevent it from wobbling, as this can increase the diameter of the hole. If this happens, a larger screw may need to be used.

Safety Consideration When Drilling Pilot Holes

When working with power drills, it is very important to take note that most power drills operate with high RPM or rotations per minute. Thus, this power tool must be handled carefully. You should always wear protective gear for your eyes and hands to prevent any accidents and injuries. Moreover, you should also the manual of the tool for the manufacturer’s operating instructions as well as the guide for safety precautions.

Opt To Pre-drill A Pilot Hole On Hardwood

Holding screws in place is ideal if you are working on pine woods and the same type of wood. However, if you are working on the hardwood, you have to pre-drill a pilot hole. This should make the job easier.

Applying Additional Pressure Using Your Hands Or Shoulders

If you notice that the screwdriver bit is slipping out of the head of the screw, this would mean that you are not applying enough pressure on the tool. To address this problem, you can compensate the applied pressure by pushing down harder on the top of the back portion of the drill using your left hand. Moreover, you can also put your shoulder into the screwdriver to apply additional pressure on the tool.

Achieve Controlled Pressure By Using On And Off Technique

You have to remember to ease back on the pressure once you notice that the screw is almost in place. If you fail to do this, the screw will end up sinking deeply into the wood. You can make use of the on and off technique as this can give you more control over how deep the screw that you are working on is driven into the wood.

Practice First Before Working On The Actual Project

If you are fairly new to using a cordless screwdriver, you have to make sure that you practice on a piece of wood first before working on the actual project. With practice, you will learn how to control the tool. It is also worth reading the manual of your power tool and learning about the different features of the tool, as this will ensure that you will know what to do when working on the actual project.

When it comes to ensuring that your tool performs well is preventive maintenance. Here are some tips that can help ensure that your cordless impact wrench will work properly while on the job.

Lubricate Your Cordless Impact Wrench Properly

Unlike most pneumatic impact wrench which should be lubricated daily, a cordless impact wrench should be greased every few months, depending on the application as well as usage of the tool. Lubricating your cordless tool properly will help extend its life. In addition, this should also help improve the tool’s performance. The areas that need to be lubricated are those parts where you can hear noise from the tool when the tool is powered on. If there is a change in this noise, you can wipe off the old grease and reapply new lubrication to improve the tool’s performance. If you are in doubt, you can check the tool’s manual to determine which parts of the tool require lubrication.

Wipe Fuels and Solvents on the Tool Immediately

When you are using your cordless impact wrench and it has come in contact with fuels and solvents like a thinner, gasoline, and acetone, you should wipe them away quickly. You should use a paper towel when wiping the tool but skip using any cleaning solvent. You should also skip abrasive cleaning as this can affect the appearance of the housing.

Keep Dirt and Debris Away from the Tool’s Openings

When using a cordless impact wrench, you have to make sure that you keep any dirt, debris or perhaps metal fillings away from the openings of the tool’s housing. Dirt and debris can actually affect the tool’s performance. Moreover, it can become stuck in the tool’s mechanism. This can result to damage on the different parts inside the cordless impact wrench.

Store Batteries Properly and Ensure Proper Charging

In the past, it has been a considered a concern when it comes to preserving the life of cordless impact tools like the cordless impact wrench. However, with recent advancements in technology, there is no memory effect on the new and improved lithium-ion batteries of cordless tools. You just have to keep in mind that the life of this type of batteries is maximized if you keep then in 50 percent stage of charge. Additionally, it is normal to charge the battery overnight. In fact, this will not have a negative effect on the battery and its performance.

Use the Appropriate Type and Size of Accessories for a Cordless Impact Wrench

When using cordless impact wrenches, it is important to take remember that you should use the right type of accessories for the tool. Impact wrenches are designed to work with impact sockets. Thus, you have to make sure that you use one when working with a cordless impact wrench. Using regular sockets with a cordless impact wrench affects the performance of the tool. In addition, this also poses a significant safety concern while in the workplace. A regular socket cannot withstand the amount of torque that an impact wrench delivers. The regular socket can shatter and become a safety hazard.

Regular sockets cannot handle high torque delivered by an impact wrench because of the materials used to make the sockets. Regular sockets are created using chrome, which is fairly brittle and can shatter when subjected to excessive vibration. On the other hand, impact sockets are made from a more malleable and softer material that allows it to absorb vibrations and higher impact.

Wear the Right Protective Gears

When working with cordless impact wrenches, you have to remember to wear the right protective gears. Just as with any other power tool, it is important to be mindful of personal protection. It is vital that you wear eye protection and gloves when working with a cordless impact wrench. The glove type that you need to use will depend on the type of job that you are doing. It is also a good idea to wear protective headgear, especially if you are working on projects over your head.
