Which is better oil based polyurethane or water based?

Durability of Water Based vs Oil Based Polyurethane

Oil based used to be unquestionably more durable. Today though, water based polyurethane has evolved with better formulations that are equally durable as oil based polyurethane.

What is the downside of oil based polyurethane?

Cons of Oil-Based Polyurethane

Longer dry times. Dents easier due to it softer finish. The odor is unbearable (respirator use is recommended). The floor darkens over time.

What is the main disadvantage of using water based polyurethane?

Cons. Water-based polys cost twice as much as oil-based polys. They won't give wood the rich glow that oil-based polys impart; some even consider them cold looking. Some waterborne polys go on so clear that you'll have to mark each swath of finish as you go.

Is oil or water based polyurethane stronger?

We generally recommend and apply 3 coats of oil based polyurethane. Water based finishes will lay out thinner, but are slightly harder than oil based.

Is oil or water based polyurethane better for furniture?

Should I use water-based or oil-based poly? A: If you're looking purely at durability, then an oil-based polyurethane is still superior, but only marginally. There used to be distinct differences between water- and oil-based polyurethanes when it came to durability. Today, the differences are fairly minor.

Quick Tip #6 - Oil

How long does oil based polyurethane last?

Gloss oil-based varnish, polyurethane and Danish oil can last 10 or 20 years, though satin finishes and stains may fail sooner as pigments and flattening agents disable the driers. Water-based coatings and paints can also be viable longer than three years. Shellac, though, can go bad in under a year.

Does oil based polyurethane yellow over time?

Oil based polyurethanes turn the floors yellow…and over time, they become more yellow…and sometimes even a bit orangish. It's the UV rays from the sun that turn them a darker yellow or amber and the more they are exposed over time, the yellower they get.

What is the most durable wood finish?

Oil-based polyurethane is the most durable finish you can apply by hand, and catalyzed lacquer and varnish are the most durable sprayed finishes.

Does oil based polyurethane dry clear?

COLOR: Oil based poly has an amber hue, whereas water based poly is clear. An oil based polyurethane will continue to amber and darken over time, while water based poly will remain clear for the lifetime of the hardwood floor.

Is 3 coats of polyurethane enough?

For ideal results, you should use about three or four coats. You will also have to wait quite some time between coats, as this polyurethane takes longer to dry. No matter how many coats of polyurethane you apply, it will always be quite a time-consuming process when using an oil-based finish.

Can you sleep in house after water-based polyurethane?

No, it is not recommended, and you shouldn't take chances. Polyurethane will be off-gassing heavily for the first 24 hours, even for the water-based type. It is worse if you use oil-based finishes: it's highly toxic and can cause several health problems.

What is better oil based or water-based stain?

Oil-based stains are stronger and usually more durable than water-based stains. One reason for this is that oil-based stains take longer to dry so the stain has more time to harden than water-based stains.

Which is better Polycrylic or polyurethane?

The formula has an acrylic base; polyurethane is added for better adhesion and durability. Polycrylic is not as durable as polyurethane and is meant to be used only on interior surfaces such as cabinets, furniture, and trim.

Can water based poly go over oil based stain?

Can You Use Water-based Polyurethane over Oil-based Stain? Yes, you can apply water-based polyurethane over oil-based stain. You may be thinking, “But oil and water don't mix,” and you'll be right. You won't be mixing them; you'd just be applying the polyurethane over the stain.

Is oil based polyurethane waterproof?

Neither oil-based poly nor water-borne poly is waterproof. Instead, they are water-resistant and will create a protective coat on the wood surface, resilient to water and moisture damage.

What is better lacquer or polyurethane?

Despite being available in variances, polyurethane is more durable. It is thick and leaves a strong coating. Lacquer is thin and penetrates the wood surface. It is also durable but susceptible to scratches and discoloration after some time.

Will water based polyurethane turn yellow?

Water-based polyurethane rarely turns yellow over time. This is because the polyurethane has a very low level of oils in the coating. Also, water-based polyurethane has a low level of VOCs, paint chemicals, and solvents which means the paint coating is less likely to react or turn yellow.

What is oil based polyurethane used for?

Oil-based polyurethane coatings provide excellent abrasion and scratch resistance. This makes them a good choice for wood floors or for any application such as cabinets, railings, or countertops where durability is critical. Oil-based polyurethane coatings achieve a rich, golden glow in few coats.

What's the difference between satin and semi gloss polyurethane?

The key difference between satin and semi-gloss polyurethane is its appearance. Satin reflects less light, giving it a duller, low-sheen appearance, while semi-gloss reflects more light, making it more lustrous and shiny.

What is the toughest polyurethane finish?

Moisture-cured urethane is considered one of the hardest finishes available, but also has one of the highest VOC's. Because it dries so fast, it's difficult to apply, so it's not recommended for DIY'ers.

What is the hardest clear coat finish for wood?

What kind of polyurethane does not yellow?

To avoid a yellowing wood finish, use a water-based polyurethane instead of an oil based polyurethane. The best water-based polyurethane is Minwax's Polycrylic, which is formulated for easy consumer use.

Does oil based polyurethane darken wood?

An oil based polyurethane will continue to amber and darken over time, while water-based poly will remain clear for the lifetime of the hardwood floor. This color difference is less noticeable over a stained hardwood floor, but an oil based poly will still exhibit an amber hue that will continue to darken over time.

What finish does not yellow?

Acrylic based finishes, both water and solvent based are the best choice for non-yellowing finishes. Waxes also will not yellow as well as some catalyzed lacquers and varnishes.
