How Long Does It Take for Latex Paint to Dry? (& Speed Up Tips)

Waiting for latex paint to dry before sanding, recoating, or sealing is important if you want a good finish. So how long does it take for latex paint to dry? 

Latex paint dries to touch in about 1 hour. Each coating of latex paint can be recoated safely in about 3 hours. However, it takes at least 48 hours for latex paint to cure. On average, most latex paints take about a week to fully cure.

The drying time of the latex paint is quick because the paint is water-based. The water-based nature of the solvent makes it evaporate quicker so the paint pigments can solidify faster.

However, that’s not all. This post reveals more about the drying time of latex paint including 5 simple hacks that you can use to make latex paint dry faster.

So let’s dive in.

Dry Time Between Coats of Latex Paint

Most of us apply multiply coats of latex paint. So, how long should latex paint dry between coats?

It takes between 2 hours and 5 hours for water-based or latex paint to dry between coats. On average, it takes 3 hours for latex paint to dry between coats.

Usually, the first latex coating can be recoated safely in less than 4 hours. The final coating usually takes longer because it has to cure before a sealant can be applied. It can take up to 2 weeks for latex paint final coating to fully cure.

Latex paint has the fastest drying time of any paint type. The paint dries to touch within the first hour after application. This is because the paint uses water as its solvent and water evaporates from paint pigments quickly.

Also, the paint doesn’t have a high volume of strong chemicals, oils, and volatile organic compounds. This means that latex paints don’t require any chemical reaction to bond and cure. So successive coats can be applied quicker.

The drying time of latex paint between coats is also subject to certain factors. These factors include room temperature, humidity, and weather.

Latex paint like any other paint should be applied at the right room temperature (between 50 – 85 degrees F). The paint also should be applied during the day and in a dry and dust-free environment.

If all of these conditions are maintained, then the latex paint will dry for recoat within 3 hours. However, if the paint isn’t applied under the required conditions, the latex paint coating will take a longer time to dry enough for a recoat.

Different Drying Stages of Latex Paint

Latex paint goes into different stages of drying — dry to touch, dry to recoat, dry to use and curing time. It takes about 4 weeks for latex paint to fully cure. But, that doesn’t mean you can’t use the object you just painted before that

Dry To Touch

The dry-to-touch stage is when you can touch the surface you just painted and the latex paint won’t stick to your hand. This usually happens 30 minutes after you applied the paint. The “dry to touch” is when the solvent has evaporated from the top coat but hasn’t evaporated underneath the paint. 

So, while you can touch the latex paint, it doesn’t mean you can apply another coat over it. If you apply another coat while the solvent hasn’t evaporated completely, you will end up with sticky latex paint. 

Dry To Re-coat

The “dry to re-coat” time means how long should latex paint dry before you can apply another coat over it. The more coats you apply, the longer the dry time to re-coat is. However, you have to wait for 1-2 hours for the first coat to dry before you can apply another coat over it. 

When 2 hours have passed by, latex paint has evaporated most of its solvent and the paint particles have bonded enough to accept another coat. The wait time can be longer if the temperature is low and the humidity is higher than 50%

Dry To Use

“Dry to use” refers to the time to wait until you can use the object you painted. For example, if you just painted a chair, you have to wait until the paint dried properly before you can sit on it and use it. This takes between 24-48 hours, but it can take longer if the temperature isn’t ideal and the humidity is high. 

Also, if you didn’t wait enough time to re-coat the latex paint, the “dry to use” will take even longer. 

Cure Time

The “cure time” refers to the time when the solvent has fully evaporated from the latex paint and the paint particles have bonded and hardened perfectly. This is the time when you can wash the object you just painted and the paint won’t come off. This usually takes 2-4 weeks. 

How To Make Latex Paint Dry Faster?

Latex paint dries quickly but maybe you are in a hurry and you need the latex paint coating to dry faster. Here are 5 effective methods on how to speed it up:

  1. Use a Hair Dryer
  2. Open More Windows
  3. Thin The Latex Paint
  4. Apply Thin Coats
  5. Paint During The Day

1. Use a Hairdryer

Use a Hairdryer

The key to making latex paint dry quicker is to make the solvent evaporate quicker. When the solvent (water) in the paint pigment is fully evaporated, the paint will dry.

You can use a hairdryer to make the solvent evaporate quicker.

To do this, turn on your hairdryer and move it over the painted surface. Don’t let the dryer come in contact with the painted surface. Just keep it a few inches from the surface and hover the hairdryer across repeatedly.

Hairdryers are designed to make hair dry faster. This design can also work to make latex paints dry faster. You can also use infrared heaters.

As an expert tip, stay away from heating equipment that can produce intense heat. This means no heat guns. 

2. Open More Windows

Open More Windows

Another hack to making latex paints dry faster is to allow sufficient ventilation.

As stated earlier, the paint will dry quicker if the solvent is evaporated quicker too. Allowing air or proper ventilation in the room will make latex paint coatings dry faster.

You can also turn on the fans in the room or install more fans for more air. Air will work just as well as heat on latex paints.

3. Thin The Latex Paint

Thin The Latex Paint

Another method to make latex paints dry faster is to thin the latex paint. This means mixing the latex paint with a base or solvent to make the paint lighter.

To thin the latex paint, you can add water to it. But be careful of the amount of water added so you don’t over-mix the paint. Usually, you need just 1/4 cup of water for a gallon of latex paint. Then stir the paint until there is color and flow uniformity.

Thinned latex paints dry faster.

4. Apply Thin Coats

Apply Thin Coats

Latex paint like every other paint takes longer to dry if thick coats are applied. Thicker coats mean more latex paint and subsequently more drying time.

To make latex paints dry faster, apply light or thin coats on the surface. Thin coats dry faster because there is less paint and subsequently, less drying time.

If you apply thin coats, you can cover larger areas quicker and even recoat faster. Thin coats are also easier to control and are less likely to drip.

Another hack similar to thin coats is fewer coats. Usually, 2 coats of latex paint are enough if a primer is used before painting. 3 coats of latex paint or more and you are sure to wait longer before the paint coating dries.

5. Paint During The Day

Paint During The Day

Painting during the day will make latex paint dry faster. When you paint during the day, especially between 10 am and 4 pm, the latex paint will dry quickly because the weather is warm.

Painters usually advise finishing paint application before noon. This is because the weather is guaranteed to get hotter by noon. So it’s best to take advantage of the hot weather to dry the latex paint coating.

Painting at night isn’t ideal because the weather is cool at night. This will cause the paint to take longer to dry.

Other tips that can help you get a faster drying time are to paint at the right room temperature and ensure the humidity is not above 50%.

What Happens If You Recoat Latex Paint Too Soon?

If you recoat latex paint too soon, the new coat will not adhere well to the existing coat. The latex finish will also split and peel off after a few weeks. This is because the existing coat hasn’t cured.

Also, the finish will have a whitish appearance. This is because moisture is still trapped in the paint coating. You will also notice streaks and uneven colors when the paint dries.

Latex paints can be deceiving when it comes to drying times. This is because the latex paint can be dry enough to touch in a few minutes.

Many DIYers confuse this to mean that the second coat can be applied. This is usually not the case. The paint solvent has to be fully evaporated before another coat can be applied and this will take a few hours.

To experiment with this theory, apply a latex paint coating on a surface. Then leave it to dry enough to touch. After, place a large drop sheet on the latex paint coating and tape the drop sheet down for about 2 hours. After 2-3 hours, raise the drop sheet. You will notice tiny droplets of water or moisture trapped on the underside of the drop sheet.

This is what happens when you apply a second coat of latex paint too soon or finish the final coating too soon. The large drop sheet placed on the latex paint coating serves as the second coat of latex finish.

This coat prevents air from getting in. This increases the heat under the drop cloth. The increased heat causes increased evaporation of the paint solvent from the paint pigments. This is why you noticed moisture trapped underneath the drop cloth.

Since the drop cloth was another paint coating, the moisture being evaporated will prevent good bonding. And, the whole paint coating will split and begin to peel off.

Why Does Latex Paint Stay Tacky?

Why does latex paint stay tacky even after it has been dried?

Latex paint stays tacky due to improper surface preparation, lack of a water-based primer, and or painting in a moist environment. When latex paint isn’t applied under the right conditions, the paint is bound to remain tacky or sticky even after the required drying time has elapsed.

Though latex paint dries quickly, the paint still needs to be applied on a clean and smooth surface.

If latex paint is applied on a greasy or filthy surface, the paint coating will remain tacky or sticky. This is because the latex paint was applied on the filth or grease rather than the surface.

The dirt and grease on the surface will repel the paint coating and prevent adhesion. Since the paint doesn’t adhere properly, it can’t dry well. This will cause some parts of the paint coating to dry while other parts will remain sticky or tacky.

Latex paint will also remain tacky if a primer wasn’t used. Water-based primers are used before applying latex paints to improve paint adhesion and seal holes in the surface.

If you don’t use a primer, the surface to be painted will be riddled with pores or tiny holes. These holes will suck the latex paint causing uneven paint application. Uneven paint application will cause the latex paint to stay tacky.

Another reason latex paints will stay tacky or sticky is if the paint was applied in a cold or moist environment. When humidity is more than 50 percent in the room, the paint will take longer to dry. This means the latex paint will remain sticky even after the required drying time has elapsed.

So to prevent latex paint from being tacky, use a good primer and ensure proper surface preparation.

FAQ’s

How Many Coats of Latex Paint?

Latex paint is thicker than most water-based paint. So, you need just 2 coats of latex paint to properly cover a surface. You shouldn’t apply more than 3 coats of latex paint because it can turn sticky if you don’t wait enough between coats. 

Does Sanding Speed Up Drying Time?

No, sanding doesn’t speed up drying time, But, sanding can help latex coats to stick better. If latex paint coats stick properly you will get a durable finish, If the coats don’t stick properly, latex paint will turn sticky and peel off. 

Final Words

Overall, latex paints dry quickly due to the paint’s thin and water-based nature. However, you can speed up the drying time by using any of the hacks revealed above.

Always ensure the surface is properly prepped and use a primer before applying latex paint for the best results.
