However, they can confuse new DIYers since they have a similar name and purpose.
Polycrylic is a light-duty sealant that dries quickly with a clear or slightly milky hue.
It’s low in flammability and volatile organic compounds (VOCs).

Polyurethane is better forhigh-traffic areaslike wood floors, though it does take longer to dry.
Oil-based polyurethane is a flammable product with a high level of VOCs.
Water-based polyurethane still has a higher level of VOCs than polycrylic.
The Spruce / Sanja Kostic
Polyurethane can be either water-based or oil-based.
Polyurethane costs more, at about $20 to $50 per quart.
It dries with a clear or slight yellow hue and generally lasts three years before needing to be refinished.
snag the best option based on the look of your finished project.
Remember that polycrylic tends to appear milky white during system, though it is typically clear when it dries.
If you apply the polycrylic in thick coats, it may retain a slight milky white hue.
The appearance of the polyurethane sealant depends on whether it is water-based or oil-based.

There isn’t a significant difference between these products.
This is because polycrylic only has a mild to moderate resistance against water and heat.
Use polyurethane to protect your woodworking projects and delicate furniture for a more water and heat-resistant option.
Water-based polyurethane does not have the same resistance as oil-based polyurethane.
In this regard, oil-based polyurethane is the best choice.
Fortunately, polycrylic can be cleaned with only soap, warm water, and little physical effort.
However, oil-based polyurethane must be cleaned with mineral spirits or paint thinner.
This finish should protect the object from physical damage, like scratches or dents.
Polycrylic is a durable choice that can provide moderate protection to wooden furniture or floors.
This durable finish protects the underlying wood to keep the object in good condition, even in high-traffic areas.
It dries quickly, making it a great choice for small woodworking projects.
Polycrylic should be applied with a brush or sprayer in three thin coats.
Polyurethane is generally easier to apply than polycrylic because it has a thicker consistency.
Use a brush or sprayer to apply polyurethane in about three coats.
Polyurethane is a better option for finishing large woodworking projects.
However, polycrylic is a non-flammable, low-VOC option that is easier indoors than polyurethane.
It also dries noticeably faster, making it a good choice for small woodworking projects.
Cost
If finish cost is a deciding factor, then polycrylic is the way to go.
Regarding the price, polycrylic and water-based polyurethane are about the same.
Oil-based polyurethane costs slightly higher, ranging from about $20 to upwards of $50 per quart.
Polyurethane has essentially the same lifespan as polycrylic.

In this category, both polycrylic and polyurethane are equal.
Polycrylic is a non-flammable sealant that doesn’t have a strong chemical odor.
It also has lower VOCs, though working in a well-ventilated space with an appropriate mask is still recommended.
Polyurethane is not an environmentally friendly option.
Water-based polyurethane isn’t as bad as oil-based polyurethane, but the VOC count is still relatively high.
Always check that to work in a well-ventilated area when you are applying polyurethane.
Water-based polyurethane is better than oil-based polyurethane but isn’t as environmentally friendly as polycrylic.
It is more durable than polycrylic, allowing it to hold up better than polyacrylic.
Oil-based polyurethane is the best option for finishing high-traffic wood flooring or commonly used indoor furniture.
Use only polyurethane products labeled for outdoor use on exterior projects, whether water- or oil-based.
