Wood Whiz- Eric Hawkings

Welcome to woodwhiz.com. My name is Eric Hawkins. I love all things wood. After getting a degree in engineering, I followed my passion of working with wood in different capacities like woodworking, staining, polishing, oils, crafts, finishing, refinishing and much more.
Most of my family and friends call me a wood wizard. Whenever I can help them with their projects I do but I soon realized that the problems they were encountering were not unique. Many people on the internet were having  similar issues. So one day I thought, why not create a space where I can help more people with all wood related issues. So the idea of ‘ woodwhiz.com’ was born!

FAQ's about Oil-Based Polyurethanes

For woodworking oil-based polyurethanes are abundant and easy to use, but there area few questions surrounding their application and how they age. Read on for more information about these amazing products.

Typically a finish will last around 10 years, with good care up to 20. The amount of sunlight and the amount of use that the piece in question gets will determine the overall life. Some finishes can last up to 30 years with good care, but 15 years is a typical mid point. At a minimum you can expect 10 years of life out of a good finish. You might have to touch up once in a while and when necessary you just sand it down and apply another layer to refinish the piece.

Oil-based polyurethane are not completely waterproof, but they are water resistant. It can be used outside and in places that get wet, but should not be used in places where water will pool and sit for long periods of time. For general use it’s close enough to waterproof and it does seal wood to prevent damage. A sealed deck won’t rot and the side of a house won’t get damaged, but you wouldn’t want to use it to seal wood at the bottom of a pond or in a water feature.

An oil-based polyurethane will darker or apply an amber hue to wood over time. This often leads to a richer look, but can be frustrating if you want your wood to look exactly like it did when you made or bought the piece. The darkening process can be slowed by limiting the amount of sun exposure, but generally you will notice a slight darkening effect over time. Sanding down the old coats before applying new ones when resealing the piece in question will reverse the effect for a time.

You do not typically sand the final coat of polyurethane when finishing a piece. Many people do thin the last coat and then buff it to a smooth finish. Sanding unless done with a very fine grit and done extremely lightly will lead to a cloudy finish that ruins the effort put into the piece. This makes it even more important to sand the lower layers to ensure a smooth finish.

 

You can use tung Oil with polyurethane and it’s actually a great way to get the best finish. tung oil helps create a more rustic yet rich look, making it look like you put in more time than you did on your finish. Many professionals prefer a mixture of tung and linseed oils to be used with their polyurethane.

Oil-based polyurethane does yellow a tiny bit, but modern versions do so less than older ones. The yellowing is of a light amber hue, and light coats with proper drying time between them lead to less yellowed pieces than improperly applied coats. The yellowing effect will get a bit darker over time, so plan for this process to take place.

    My daughter is opening up a salon in an older warehouse. The floors are natural wood , no finish. Someone told us to get oil based polyurethane. We are concerned that if hair color or bleach gets spilled on the floor, that it will stain the floor. We don’t have time to sand the floors at the present time.. PLEASE help

  • Eric Hawkins says:

    Hello Marty,

    Thank you for your question. For a Hair Salon, I suggest avoiding hardwood flooring in the treatment areas that is more prone to stains and moisture. You can install a different kind of flooring in that particular section. Hope that helps.
