When you paint polyurethane with a brush, there is a much greater chance of creating bubbles on the polyurethane surface. You also have to be incredibly careful when brushing, as there is always the possibility of leaving brush marks and bumps in the finish. You could also trap moisture in the polyurethane when brushing incorrectly which will result in a cloudy finish. Choosing to use polyurethane spray removes these difficulties.
Lacquer is famous for its super high-gloss look and is one of the smoothest clear finishes available. Wood finishing with lacquer requires a high-volume sprayer as it cannot be applied with a brush without leaving noticeable brush marks. Shellac is actually a natural product made from secretions from the female lac bug.
Advantages Of Water Based Polyurethane:
For my taste, that would be something like mahogany or walnut. I was drawn to Waterlox initially for three reasons. First, it’s a tung oil product, and tung oil has been used to seal hardwood floors for a very long time.
Then, you can remove the excess mineral spirits by blotting the brush on an old newspaper. There is little chance of bubble formation with wipe-on polyurethane. You have to sand and smoothen the surface between coats. You don’t need to apply the number of coats that you need for wipe-on poly.
Wet Sanding The First Layer
Where you’ll see the yellowing over time is on lighter woods, like unstained pine. If you ever have had to deal with hardwood floors, this product must ring a bell. Being a household name, this polyurethane product is one of the best products out there with maximum durability. It has an awesome coverage capacity as one gallon could cover up to 500 square feet.
Wood finishes keep moisture out of the wood and keep it from swelling and cracking. While there are many products available, wood finish comes in two different types – penetrating finishes and surface finishes. The biggest reason people stain wood is aesthetics.
Should You Apply Sand Between Coats?
I am painting furniture and read that you should seal it with a polyacrylic sealer. Trying to find out if there’s a difference in “acrylic” vs “urethane” when applying finish over paint. You can use a variety of application methods to apply this finish. Synthetic bristle brushes, foam brushes, and lambswool applicators are all suitable options for interior wood surfaces.
Maple flooringis, most commonly installed because of its natural creamy, light color and very rarely stained because of this. When applying an oil-based poly, it will turn the Maple hardwood floors a warm light-yellow color. For this reason, it’s completely recommended to apply a water bourn polyurethane on this particular species of hardwood flooring to avoid this yellowing effect. As you can see from this picture, the difference is pretty dramatic.
The Difference Between Matte, Satin, Semi
Water-based polyurethane only really gets a great finish from the final coating, while oil based products require fewer coats due to a better finish with each coat. When it comes to finish, most people varathane vs minwax prefer oil-based polyurethane. Should you spray water based polyurethane or is it better to use oil-based polyurethane? Both types work well in their own ways and offer unique pros and cons.

And, at those points in time, the water based poly looks way worse than the oil based – in fact, it’s usually peeling off and the hardwood is starting to look gray. What’ s also interesting is that almost all of my customers who have had water based polyurethane tell me they would NEVER do it again. They felt mislead by their previous flooring contractor. While sanding and refinishing is not terribly expensive, it can be rather inconvenient if you live in the home. You need to move all the furniture out and often go away for a week.
One of the most popular penetrating finishes is danish oil. It’s made from a mixture of tung oil and varnish and is incredibly easy to use. After using a tack cloth to remove any debris from the wood surface, danish oil is applied with a rag and rubbed into the wood. Wet sanding the wood with fine-grit sandpaper before the second coat results in a super smooth finish that is highly desirable.
It gives durable beauty and protects any interior wooden surface. It is considered one of the most durable coatings for the protection of wood. It is used ideally for wood related work, furnishing work, wooden doors/cabinets/floor. Varathane and Minwax offer some of the best wood preparations and stains available. They both produce a broad enough variety that you can find anything that you may want whether it be water or oil-based. Staining wood is a way of adding character the room it is in and makes all the difference in the quality of your furniture or floors.
This means you must sand dry layers of polyurethane to assure adhesion of the next layer between coats. Ordinarily it will take 24 hours between applications. Satin isn’t shiny like a semi gloss, but some light does reflect off it. If you have a local Home Depot, Lowes or another hardware store, they often have polyurethane sheen cards in the stain section. I would recommend checking them before making a decision.
- If brush marks are left behind after applying the polyurethane, they can be sanded away with very fine sandpaper.
- Oil-based polyurethane products were considered superior in terms of longevity and durability.
- Oil base polyurethane not only has a warm golden hue, making natural hardwood flooring warmer in color, but also ambers over time.
- In other words, it isn’t a bold brown yet a subtle brown that can be perfect for that dresser you’ve been wanting to stain.
- Not only does that save you time in the moment, but it makes the entire project go by quicker.
- As with all of their finishes, the Ultimate Polyurethane Oil-Based finish lasts a long time and offers damage protection.
- Of course, you can apply water-based polyurethane directly over a wood stain.
- Without sanding back some of the dark stain, a lighter look can not be achieved with lighter stain.
- Try to choose one that works best for your needs and work.
This is is a strong and versatile solution for all kinds of projects. Rust-Oleum, a well-respected brand, has created this finish to be scratch-resistant and anti-yellowing. This finish can be used over a range of indoor uses, including furniture, trims, doors, cabinets, and more. This polyurethane dries to a clear satin finish which makes it enhance the look of the wood underneath it.
There is no contest on the durability between the 2 options. Water based polyurethane has lower VOC’s – which is a bit of an environmental benefit – but because it has lower VOC’s , it doesn’t last as long. Water based poly is thinner, and you often need 4-5 coats to equal the durability of 3 coats of oil based. This is because I normally use an oil based stain and finish, so I just wanted to be consistent. I do have a water based one as well, but I didn’t test it. Using an oil-based stain creates a more traditional look when finishing furniture.

Exterior finishes are typically designed to be more flexible to allow moisture to enter and evaporate out of the wood, but they require sunlight to evaporate. I used to think that exterior products must be better and more durable since they are designed for exterior uses. In fact, many interior use products are really excellent on table tops, floors, and other applications where they stand to be exposed to heavy wear and chemicals.
Wipe On & Brushing
There are other methods of coloring and staining wood besides what I have shown here, each with their pros and cons. Some of the methods do not require conditioning the wood, even with woods such as pine. If you have a large project then I suggest segmenting it out so that you can keep up with the conditioner that you apply. I use this wood because it is relatively cheap, especially compared to certain hardwoods. Of course pine is not really great for “fine” woodworking, but its good enough for me.
You can easily wipe away drips and spills with warm water. If you’re sensitive to smells, you’ll appreciate this water-based polyurethane’s mild to non-existent odor. Since Bona Mega never yellows, it’s an excellent option for dull, white, and gray wood.
You need to use a wood conditioner when applying stain to pine. Wood conditioner is usually just one part varnish with two parts mineral spirits. It is not a complicated formula and it can differ based on what the finisher wants to do with the rest of the project. Different topcoats will require different wood conditioners.
That specific finish is perfect for adding a nice, warm sheen to your wood. As with all of their finishes, the Ultimate Polyurethane Oil-Based finish lasts a long time and offers damage protection. Wood finishing products serve more purposes than just enhancing the look of the wood it is applied to. In fact, without adding a wood finishing product to the wood, it would be susceptible to damage. Adding a finish to the wood protects it from scratches, humidity, dents, and spills. Two of the leading wood finishing products that make the search easier are Varathane and Minwax.
If you want to keep the wood’s natural look and are willing to go with the less durable option, a water-based poly is what you’re looking for. Extremely helpful breakdown of the two products without all the non-sense you don’t need. Your summery was also a nice touch to wrap things up. My project happened to be removing the paint from a Guitar neck and going bare with a light cover of protection. So far, I’m very happy with the results and the product was very easy to use. Both spar urethane and polyurethane are good compounds that you could use to achieve fine quality finishing.
In fact, adding naphtha probably has no noticeable effect on the drying of the finish beyond the impact of thinning described at the end of the second myth. Some brands of polyurethane, such as Minwax, bubble noticeably more than others, but this is rarely a problem because the bubbles tend to pop out quickly. Polyurethane bonds especially poorly to sanding sealers, so most manufacturers of polyurethane discourage their use. Furthermore, polyurethane sands easily, so there isn’t any need for a sanding sealer.
Just like with other kinds of paints, wooden finishes may require more than one coat. The recommended number of coats is a critical factor to keep in mind before purchasing a water-based or oil-based wood finish. If you have to apply several coats, you will spend more time finishing the wood, and the price of your project can increase. One of the big draws of water based polyurethane is that it doesn’t have much of a smell and it dries quickly. Oil-based polyurethane, on the other hand, is known for its distinct aroma.
Minwax is a brand that has been manufacturing wood preparation and finishing products for more than a century. This company is known for products that deliver excellent protection for your wood which last a long time. Condition the wood.After sanding wood, using something like Varathane’s Wood Conditioner or Minwax’s Sanding Sealer to prepare the wood. If you jump right into staining without preparing the wood, the stain simply will not take or dry the way that you want. Oil-based polyurethane seems to be where it’s at as far as having a finished product that’s sustainable and doesn’t fade over time. However, the application process is a bit more involved than a water-based product.
For every 10-degree drop in temperature the viscosity increases by 10 percent. You might find that the best solution for your problems is just to raise the temperature in your spray area. First, before you even begin spraying, you should be more diligent than with lacquers to strain the finish. Solid pieces of lacquer falling into the finish from the lip of the can dissolve back into the finish.
