A sleek glossy and luxurious great finish on your wooden projects will make them look pleasable to the eyes. And to overwhelm you with that certain look is the reason why the polyurethane exists.

However, as we said before, the answer is not quite finished right there. There are various kinds of paint and different dry times for them. And even there are paints that donâ€™t even require the polyurethane.

Types Of Paint For A Wooden Surface
There are variations of paints that you can use on a wooden surface. Each of those has different and itâ€™s own unique qualities. So, weâ€™re going to check out what you have in hand:
Latex paints are available around you and work quite perfectly on a wooden surface. Youâ€™ll find them at the local home improvement stores or hardware stores.
Professionals consider the latex paint one of the easiest paints to work with when it comes to painting a wooden surface like furniture.
You can get by without a top coat of polyurethane if you use something with a semigloss or gloss sheen. It totally depends on how much surface youâ€™re covering with the paint.
However, if youâ€™re using a flat, satin, or eggshell latex paint on a surface, youâ€™ll need the polyurethane to give it a finishing touch. That topcoat will be adding protection to the paint.
Also, to minimize the brushstrokes, you can use a good high-quality paintbrush and mix a little Floetrol in it.
Now, how long does it take latex paint to dry? Well, it takes about 1 hour to dry but if you want to safely recoat it you should wait for 4 hours. The more you wait the better it sets on the surface.

For furniture, oil-based paint means durability over time. The finishing of the oil-based paint wonâ€™t chip as some latex paints do. On the other hand, oil-based paints are a bit harder to deal with.
Oil-based paint goes the best with a brush on the surface rather than a roller. That means that putting it on a wider surface will be quite time consuming for you.
To get it off the brush or yourself, youâ€™ll need to use mineral spirits or paint thinner.
It takes 6-8 hours for the oil-based paint to dry before you put another layer on top of it.

Since the past decade, the furniture painting has really taken off. And there have been a few specialty paints that are created specifically for painting on the furniture.
Fortunately, this velvet finish is one of those specialty paints. It has a built-in topcoat and usually, you donâ€™t need to sand or prime unless the surface is already shiny or glossy.
You should give it 8-9 hours to dry and sit completely on the wooden surface.

Another one of the specialty paints is the chalk paint. There are some chalk paints that donâ€™t require you priming or sanding the surface before the painting.
On the other hand, some chalk paints do require you to give it some sort of topcoat. You can also use wax to seal it.
However, it takes about 24 hours to let the chalk paint dry completely. After 24 hours you can apply polyurethane on it.

Factors Affecting The Dry Time Of The Paint
There are a few factors that might increase or decrease the dry time of your paint. Letâ€™s check those factors out-
Type Of Wood
There are various types of wood and some of them donâ€™t cure properly because they produce chemicals that inhibit the crosslinking process.
Now the question is which woods should you avoid?
Youâ€™ll find the rosewoods and some aromatic cedars which include this category of wood. So, avoid the surfaces that are built with those.
Type Of Paint
As you saw before, different types of paints have different drying times. Itâ€™s mostly because of the material that the paint consists of.
Temperature is a natural cause that might highly affect the dry time of the paint.
You see, some paints thicken in the lower ambient temperature and that causes a longer drying time for you. The longer it takes the more running or sagging starts.
The result of that running or sagging will turn the paint ugly and create an uneven surface. And that means youâ€™ll need the painting to start over again.
On the other hand, if itâ€™s too cold, the overall life expectancy of the paint will reduce without any doubt.
High humidity means that you have increased water vapor in the air and on surfaces.
As you know that wood is porous and will absorb any excess moisture from the air, itâ€™s problematic to paint.
And the paint might often peel off or create a bubble on its own because of the added moisture.
If you have a high humidity while youâ€™re applying the paint, it doesnâ€™t matter how many coats you use because the result will be the same.
Most of the time the paint takes longer time to dry because of the lack of proper ventilation in the area.
So, if youâ€™re painting a surface in a closed room, make sure that you allow the room to be properly ventilated in order to increase the drying time.
However, if youâ€™re painting something that you easily move, you should move it a free space like your backyard and then paint it. Itâ€™ll have the best ventilation out there.
