How Long Does Polyurethane Take to Dry?

For water-based polyurethane, the drying time is about 48 hours. For oil-based polyurethane, it takes around 48 hours to dry. After this fourth dimension, y'all can walk on the surface or bear on it. The consummate drying takes much longer.

This depends on the type of polyurethane you utilise, how you use it, and what the external weather are like. Nosotros accept outlined all of these factors in detail below.

The Dissimilar Types of Polyurethane

Before looking into drying times, you lot volition need to empathize exactly which production you are working with. In that location are diverse dissimilar types of polyurethane coatings bachelor, each 1 with a unique drying time. To meliorate understand this, we have outlined some of the main considerations below for polyurethane coatings.

H2o-Based or Oil-Based Polyurethane

First, you volition need to empathize exactly what polyurethane is and how information technology is formulated. Polyurethane coatings, or varnish, is made up of polyurethane resins that are dissolved and carried past a liquid solvent. This basically forms a type of plastic in liquid form. When looking at the liquid base of polyurethane, there are ii options: water or oil. Both of these produce very different products with unique polyurethane dry times.

H2o-based polyurethane is a safer and less toxic pick. These products incorporate far fewer amounts of VOCs – that is if they contain any at all. Water-based products exercise not produce strong odors, and they are safer and easier to work with. Because water evaporates quickly, this type of polyurethane is much faster drying. The polyurethane cure time for water-based products is also lower because these finishes produce much thinner coatings. You volition probable accept to employ more coatings though – particularly because water-based products are typically less durable.

Oil-based polyurethane is a different story. Different water-based products, these finishes are practical slightly thicker. This thickness, combined with the oil composition, makes the polyurethane dry out time significantly longer. Notwithstanding, y'all will achieve a stronger, more than durable terminate. Oil-based polyurethane can contain high levels of VOCs, and these products can exist fairly harmful due to the many chemicals. Oil-based products besides release a stronger odor.

An of import difference betwixt these ii types of polyurethane is their clarity. Both types of finish go on clear, but oil-based products will oft yellow or darken over time. Water-based polyurethane by and large maintains a better level of clarity over the years.

The Blazon of Sheen

Some other factor to consider on the drying fourth dimension for polyurethane is the type of sheen that the product has. Polyurethane varnishes come in iii different types of sheen. These are the level of glossiness, or lack of gloss, that the terminate offers after it has dried. We have outlined the different sheen types below:

• Satin: A satin finish is non equally shiny as others. This type of polyurethane has an almost matte wait, with a very minimal, subtle shine to it. How long does polyurethane take to dry with a satin coating? This type is the fastest drying polyurethane bachelor.
• Semi-gloss: Semi-gloss polyurethane offers a finish that has some shine, but is non as shiny as high-gloss options. This is the middle ground between glossy and apartment. Semi-gloss polyurethane is a popular pick thanks to its versatile nature and durability. This type of polyurethane dries faster than loftier-gloss just slightly slower than satin products.
• Loftier-gloss: High-gloss polyurethane offers a completely shiny and slick-looking finish. This type of varnish is actually durable and provides great flexibility. Loftier-gloss polyurethane can be used indoors and outdoors for various wooden surfaces. This type of finish takes slightly longer to dry.

Polyurethane Cure Time Table

At present that we have covered the basic types and formulations of polyurethane, we tin compare the different styles side by side. How long does polyurethane take to dry? Accept a expect at our polyurethane cure time table beneath to proceeds a better understanding of the drying times for each type. This is merely a general overview. It depends on the temperature and humidity, as well as the surface.

	Water-Based	Oil-Based
Fix for another Layer	8 hours	24 hours
Dried to touch	24 hours	48 hours
Placing things on the surface*	> 2 days	> 4 days
Fully cured	20 days	30 days

*Await for a calendar month before you place materials with plasticizers (e.g. safety mats) on the surface. Otherwise, y'all will take visible marks on the flooring.

Polyurethane Drying and Curing

When talking about polyurethane dry time, or polyurethane cure time, at that place is a distinct divergence between the 2. Dried polyurethane is non cured polyurethane. When asking how long does polyurethane takes to dry out, it is important to empathise these two definitions.

Drying is when the external finish of the polyurethane hardens. This just ways that the polyurethane is no longer in a liquid form, and it isn't tacky or wet. This does non mean that the coated surface is ready for use though. Dried polyurethane can nevertheless easily get damaged or wrinkled by too much pressure. If you have a floor or countertop coated in polyurethane, make certain that you do non put it under heavy use when information technology is just dry out.

Curing is a more thorough process where the polyurethane completely hardens throughout. This is when the polyurethane has been completely exposed to oxygen and has gone through a complete chemical reaction with the oxygen. Cured polyurethane is the finish in its final, hardest grade. Once cured, yous tin utilise regular pressure to the surface. Curing is a much longer process and can take anywhere between 24 hours to a month.

Factors That Influence Curing Times

Polyurethane can as well dry at different times depending on external factors. If you lot use the verbal same product in two different conditions, the drying time will change. We have outlined some of the most important factors that volition influence drying time below.

Temperature

One of the about important factors when applying a forest end is the external temperature. The best atmospheric condition would exist anywhere effectually 70 degrees Fahrenheit. If the temperature is too common cold below this, then the polyurethane will take far also long to dry. Drying in cold conditions can cause a strange white film to develop over the polyurethane. If the temperature is too hot, then this might affect the resulting stop of the polyurethane.

Humidity

Ideally, you want a humidity of fifty – 70% when applying polyurethane finishes to the woods. If the humidity is likewise high, the finish will struggle to dry out properly, and the resulting finish could be affected in the way it looks and adheres to the wood. If humidity is an issue, then it'due south best to use oil-based polyurethane. This is considering water-based products are more sensitive to humidity.

Thickness of Layers

The other factor that determines the polyurethane drying fourth dimension is the thickness of the layers applied. Quite simply, the thicker the coats, the longer the polyurethane will take to dry. This is influenced by 2 unlike factors. These are the method of awarding and the product used.

If you paint polyurethane on with a brush, the layers will more often than not be a bit thicker. This will take longer to dry. If rolled or sprayed on, the layers of polyurethane will exist thinner. This will event in a significantly faster drying time. You tin also go sure special wipe-on polyurethane products for, particularly sparse and fast-drying layers.

And then at that place is the type of polyurethane used that will influence this. Water-based products tend to be a lot thinner than oil-based products. If yous are using a water-based solution, the thinner layers volition result in a speedier drying fourth dimension. Thicker oil-based polyurethanes will be much slower.

Tips and Tricks for a Faster Drying Fourth dimension

Now that we know what makes polyurethane dry and what influences its curing time, we tin can endeavour to add our ain influences if nosotros desire to make the product dry out faster. If you are struggling to go the polyurethane to dry apace, so follow our elevation tips below to assistance get the procedure going faster.

• Apply oestrus in cold conditions. If the weather is too cold for the polyurethane to dry out properly, y'all can merely apply a estrus source to speed up the procedure. This can include things like a wall heater or hairdryer. Just brand certain that you utilise a gentle layer of rut – too much and the finish will be affected.
• If the polyurethane comes on too thick, yous can smooth it out for a faster drying time. Using a paint roller works very well. Simply roll over the applied cease to create fifty-fifty, thin layers. This also allows the blanket to be completely smooth.
• Bank check the atmospheric condition. This may sound silly, but it is then important. Always check the atmospheric condition report if y'all are applying polyurethane outdoors. If there is rain or humidity heading through, then reschedule your DIY projection.
• Water-based polyurethane is particularly sensitive to humidity. If you are applying the cease in boiling atmospheric condition, then rather choose an oil-based product. This volition dry faster in very boiling conditions, and it will leave you with a longer-lasting event.
• Make sure that the surface you lot are applying the polyurethane to is properly prepared. A clean, sanded, and smooth wooden surface will help the polyurethane to adhere better and dry faster.

How Long for Polyurethane to Dry in Layers

How long does polyurethane take to dry when painting in layers? This is important to empathize considering when you utilize this stop, you will need to practice it in multiple coats. Y'all volition need to know when to utilise the adjacent layer and when the underlying coat is dry enough.

To know when the polyurethane layers tin be applied, you will demand to empathise the deviation between dry out times and cure times. Apply the showtime layer and leave it to dry. Depending on the product, this could accept anywhere from ane 60 minutes to viii hours. When we say dry out in this case, we don't hateful fully cured though – just dry to touch.

The polyurethane should non exist tacky or wet anymore. When y'all tin can affect the finish, yous tin can apply a second glaze. The same rule applies to a tertiary coat. After the last coat, you will need to leave the polyurethane to cure fully earlier use.

You lot can use a paint sprayer to apply this cease in the thinnest layers possible. This will allow you lot to use the end much faster and in much thinner layers. Only make sure that the sprayer tin handle polyurethane. Otherwise, rolling or painting on the finish is recommended.
