How many coats of polyurethane should you put on hardwood floors?
2 coatsWe 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.
Can you apply a second coat of polyurethane without sanding?
Apply two to three additional coats of full-strength polyurethane, sanding between each coat. When applying polyurethane, brush along the grain, stretching the polyurethane into as thin a coat as possible. Always allow polyurethane to dry 24 to 48 hours before sanding, to give the surface time to cure and harden.
Can you put too many coats of polyurethane?
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.

Which is better Minwax or varathane polyurethane?
Two of the leading wood finishing products that make the search easier are Varathane and Minwax. Both Varathane and Minwax wood stains and finishes in a wide variety of colors and styles. Minwax is a better option as far as pre-stain preparations go, and Varathane offers better finishes.
Is 2 coats of polyurethane enough?
You are best off using 3 coats of water based polyurethane for the best results. … Not only is water borne polyurethane thinner, but it also raises the grain of the wood, so the floors can sometimes feel rough with just 2 coats of poly (especially if it’s a cheap brand of poly).
Do you really need 3 coats of polyurethane?
There needs to be 3 coats of Polyurethane applied, especially if you are using an oil-based finish. The first coat should be mixed with mineral spirits. This acts as a sealer and provides a barrier between the wood and the oil finish you are using. A bristle brush is needed to apply the coats.
What do you do after the final coat of polyurethane?
Sand lightly with 240-grit sandpaper between coats, then let the last coat dry for at least 24 hours. This is standard practice with any wood finishing job, and is nothing out of the ordinary. That said, sanding bare wood beforehand to create a smooth foundation is key.

one week”Full cure” will not need air to happen, thus you’ll be completely fine with applying wax one week after applying the poly. You could probably get by with less, but a week to be completely safe.
What happens if you dont sand between coats of polyurethane?
Failing to sand between coats of polyurethane does not have a significant impact on the finish. Even so, I still advise that you sand between the coats when applying polyurethane as this will help increase the adhesion between the layers to give you a more level finish.
How long does it take for polyurethane to cure?
4 weeksIt’s the curing that makes the finish hard, durable and creates the full adhesion with the floor. This curing process can take up to 4 weeks or so depending on environmental conditions (e.g. humidity) and how thick a film was applied and number of coats of polyurethane.
Are you supposed to sand 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.
How many coats of polyurethane should you put on?
For protection, two coats are the minimum, but floors and anything else that will see hard wear or occasional moisture should get at least three coats. Each coat also makes the finish a bit smoother.
