Water-based polyurethane is a type of finish that dries faster, has less odor, and is easier to clean up with water. Oil-based polyurethane takes longer to dry, has a stronger odor, and requires mineral spirits for cleanup. Both provide a protective coating for wood surfaces, but water-based polyurethane is more environmentally friendly.

What is the difference between oil-based and water-based polyurethane?
Oil-based polyurethane is made with oil as a base, providing a more durable and long-lasting finish. Water-based polyurethane, on the other hand, is made with water as a base and dries faster with less odor. Oil-based polyurethane tends to give a warmer tone to wood, while water-based polyurethane is clearer and does not yellow over time.
What's the difference between water-based and oil-based polyurethane?
Water-based polyurethane is a type of finish that dries faster, has less odor, and is easier to clean up with water. Oil-based polyurethane takes longer to dry, has a stronger odor, and requires mineral spirits for cleanup. Oil-based polyurethane also tends to give a richer, amber tone to the wood compared to water-based polyurethane.
How can you tell the difference between water based and oil base polyurethane once it is on the floor?
Generally a colour difference is the thing to be looking for. An oil based poly will generally have a browning effect on the timber that increases with age. A waterbase poly will generally give very little if any tonal change. Bear in mind that newer waterbased polys are 100% polyurethane products that will exhibit very litlle tonal change in their lifetime, but earlier products (and some "new") are co-polymers that sometimes seemed to bleach or even whiten timbers. Old solvent based poly (a product still available in some countries) will have a definite yellow coloured characteristic.
How long does it take for polyurethane to dry between coats?
Polyurethane typically takes about 4-6 hours to dry between coats.
Is polyurethane epoxy a resin?
Polyurethane isn't epoxy, but they're both resins. They're also both reaction copolymers--you get either one through a chemical reaction between two components. The difference is, epoxy contains epoxide and polyamine; polyurethane contains a complex alcohol (either a "diol" or a "polyol") plus an isocyanate.
How long should I wait to let polyurethane dry between coats?
You should wait about 24 hours for polyurethane to dry between coats.
What grit should be used to sand polyurethane between coats?
For sanding polyurethane between coats, a grit of 220 to 400 is recommended for a smooth finish.
What is the difference between oil-based and water-based polyurethane finishes for wood surfaces?
Oil-based polyurethane finishes are made with oil as the base and provide a more durable and long-lasting finish compared to water-based polyurethane finishes. Water-based polyurethane finishes are made with water as the base and are more environmentally friendly, dry faster, and have less odor compared to oil-based finishes.
How long should you wait between coats of polyurethane for optimal results?
For optimal results, wait at least 2-4 hours between coats of polyurethane.
How long does water-based polyurethane take to dry between coats?
Water-based polyurethane typically takes about 2-4 hours to dry between coats.
What is the recommended dry time between coats for water-based polyurethane?
The recommended dry time between coats for water-based polyurethane is typically 2-4 hours.
What are the differences between applying water-based polyurethane over oil-based polyurethane?
When applying water-based polyurethane over oil-based polyurethane, the main differences lie in the drying time, odor, and color. Water-based polyurethane dries faster, has a milder odor, and may not yellow as much over time compared to oil-based polyurethane.
