Is two coats of polyurethane enough on hardwood floors?
We recommend at least 2 coats of oil based polyurethane + a lacquer sealer coat as a minimum for hardwood flooring. Extra coats = extra protection, but only one coat of oil based polyurethane may be applied per day, as it needs 24 hours to dry before applying another coat.
How many coats of polyurethane do you put on the floor?
For best results, apply at least two coats of polyurethane. When working on floors, tables, chairs, and furniture that will be used often, apply at least three coats. If you are using water-based polyurethane, you can apply up to four or five coats on floors and sheds.
How many coats of finish do you put on hardwood floors?
The standard for a hardwood floor is at least three coats. This consists of one seal coat (which may be the stain) and two coats of finish.
How many coats of poly is too much?
Generally, more than 3 coats of poly doesn’t do much good. It’s really not needed nor recommended. Each additional coat needs to be buffed so you are kind of buffing off half of the previous layer. So 4 coats is more like 3.5 coats.
Do I have to sand between coats of polyurethane?
For fast-drying polyurethane and most water-based poly, it will still remain glossy even after sanding, so it won’t necessarily help with adhesion. In conclusion, it’s necessary to sand polyurethane between coats for a perfect finish.
How long does polyurethane last on hardwood floors?
What a new coat of polyurethane does is it adds another layer of protection to your floors, extending the life of the floors usually for another 3-5 years. Doing this every 4-6 years will prevent you from ever having to fully refinishing your floors again. Don’t wait until it is too late and “wear” begins to show.
Are more coats of polyurethane better?
For proper protection of the underlying wood, multiple coats are required. Oil-based finishes usually require fewer layers than water-based versions. This is because water-based polyurethane is thinner. This type of varnish is usually best after about four to five coats.
How long after polyurethane can you walk on floors?
Water, and essentially all liquids, can also damage your new floors. Thus, it’s best to wait until all coats have been applied and dried before walking through the room. After that final coat, your floors should be off-limits for 24 hours. This is the only way to avoid any damage.
Can you wait too long between coats of polyurethane?
When you recoat after 2 hours you get a chemical bond between layers. If you let it go longer than that, you need to wait 24 hours so it’s hard enough to sand and get a mechanical bond.
What type of polyurethane is best for floors?

How long should polyurethane dry between coats?
In-between Coats
Always allow polyurethane to dry 24 to 48 hours before sanding, to give the surface time to cure and harden.
Do you buff hardwood floors after polyurethane?

You are best off using 3 coats of water based polyurethane for the best results. And, this is is especially important on the 1st floor of your home and heavy traffic areas (e.g. kitchen, entryway, family room).
What do you do between coats of polyurethane?
Allow each coat to dry fully. To give the subsequent poly layers something to bond to, sand lightly between coats with 320-grit sandpaper wrapped around a hard block. Note: The first coat needs the most sanding to appear smooth; don’t worry if it doesn’t look as flawless as you’d like at first.
Does polyurethane make wood shiny?
Polyurethane wood finish is used to coat surfaces, protecting them from scratches and helping to resist water damage. Learning how to apply polyurethane can give wood furniture and flooring a glossy, smooth finish while improving its durability.
How do you prevent brush marks on polyurethane?
When the brush marks don’t resolve themselves, try a few corrective techniques.
- Use a foam brush or a lambswool applicator instead of a brush.
- Use a natural-bristle brush rather than a synthetic one if you are using a bristle brush.
- Thin your polyurethane with paint thinner, mixing it with a paint stir stick.
Can you sleep in house after 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.
