1. Oil based polyurethane looks better. It has a more depth – both in color and shine and it looks the way we expect hardwood to look. Water based polyurethane has both a duller color and a duller finish.
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.
Which is better water or oil based polyurethane for hardwood floors?
Oil base poly is a thicker product, and will build up a thicker layer of protection for your hardwood floors. It is a great choice for longevity and high traffic areas. 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.
How good is water based polyurethane?
Water-Based Polyurethane Finishes Like the oil-based polyurethane, water-based polyurethane can form a hard protective film, but more applications are required. Because water-based polyurethane dry quickly, more coats can be applied in less time than with oil-based products.
Does water based polyurethane dry faster than oil based?
It takes anywhere from 2 hours to 24 hours for the polyurethane to dry, depending on the type of polyurethane you use. Water-based polyurethane takes about 2 hours while oil-based polyurethane needs about 8 hours to dry.
Does water based polyurethane make wood waterproof?
No, polyurethane does not make hardwood waterproof, but it does make wood water resistant. Polyurethane gives hardwood its protection. It repels water and prevents water absorption, but it never fully blocks it so it will never make it 100% waterproof. Polyurethane also protects wood for scratches and discoloration.
What is the most durable polyurethane?
The best and most durable finish for water based polyurethane is Bona Traffic HD and for oil based poly, Duraseal. The steps generally get the most traffic and wear and tear (along with hallways), so it’s even more important to have a high grade finish in these areas.
Does oil based polyurethane turn yellow?
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. This holds true for viirtually all species.
Is water based polyurethane safer?
Water based polyurethane is safe to apply without a respirator, and will not stink up the house like an oil based poly. It is safe for people and pets to occupy a house while undergoing coatings of water based poly. Water based poly, an acrylic product, is a thinner, but harder coating.
What’s the difference between water based polyurethane and oil based polyurethane?
THICKNESS AND HARDNESS: Oil based poly is a thicker poly, but it is also softer. Water-based poly, an acrylic product, is a thinner, but harder coating. Oil poly can be more susceptible to dents, while water-based poly can be more susceptible to surface scratching.
Is oil based better than water based?
Oil-based paints are typically slower to apply than water-based paints, as the paint has a stickier and thicker feel to it.Application. Oil Based Drying Times Water Based Drying Times Touch Dry: 6 to 8 hours Touch Dry: 30 to 60 minutes.
What is the toughest finish for hardwood floors?
What is the hardest wood floor finish? The hardest wood floor finish is aluminum oxide, but it only comes on prefinished boards. If you want something durable you can add after installation, acid-cured is your best bet.
Can I use oil based polyurethane over water based polyurethane?
Flooring wholesalers and veteran floor finishers agree that you can recoat water-based poly with oil-based as long as the original coating has completely cured—generally 30 to 60 days. You’ll have to lightly buff the old finish with a power buffer to prepare it for the new polyurethane.
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.
Is oil based polyurethane safe?
As long as you apply polyurethane correctly, whether it is oil-based or water-based, you and everybody around the product will be safe. Even better, we have non-toxic polyurethane such as Green poly.
Is 2 coats of polyurethane enough?
2 coats of polyurethane are enough to protect the wood from moisture and contaminants. However, for added protection against water damage, about three or four coats of polyurethane would suffice.
What happens if you don’t sand between coats of polyurethane?
For some types of poly, nothing happens if you don’t sand between coats of polyurethane. However, most polyurethane will not adhere properly if you skip sanding dust nibs and brush marks on the finish. The polyurethane finish will eventually peel off or become deformed.
