Can You Spackle in Hot Weather

Weather and temperature tend to play an important factor in construction, renovation, or painting projects.

If these essential materials are not used in an ideal environment, they become more prone to failure, mold growth, cracking, and other problems. If the ambient conditions are not suitable, the materials will cause unnecessary delays and expenses. Their drying times will be reduced and they will adversely affect the health condition of the builder, painter, or DIY worker.

One such product is spackle, a thick, moldy paste-like putty or filler used to repair cracks, holes, and holes in walls. It is also known as joint compound, drywall mud, or “spackling.” It can be made from a variety of ingredients, but the most common are gypsum or plaster mixed with water.

How to rehydrate Spackling Compound

If the spackling compound is not dried and sanded at the proper temperature and weather conditions, it will experience either or all of the following: 

  • Beading,
  • Board sagging,
  • Bond failure,
  • Cracking,
  • Delayed shrinkage,
  • Joint shadowing,
  • Nail popping, 
  • Starved Joints.

As a result, you will have to wait even longer to begin painting. Extremely lengthy drying times also imply more time on the job, which costs you money.

So, don’t hurry through your current or next project. 

Read the article to find out what temperature and weather conditions are best for allowing spackle to dry for the best possible finish!

Can You Spackle in Hot Weather? 

You cannot Spackle in hot weather. This implies that if you’re working in extremely hot weather or a humid environment, your spackling will take much longer to dry. 

As a result, you must work with spackle in cold, damp weather or keep your workspace cool and less humid. Such an environment will quickly dry the spackled patches, spots, or surfaces! 

How does it normally take for the spackling compound to dry?

Spackle generally takes 2 to 4 hours to dry. However, When deciding the drying rate or duration of the spackle, several factors must be considered. 

Firstly, this varies depending on the weather and heating rate. Spackle dries extra slowly in hot weather or places with higher humidity than in areas with low moisture content. In certain instances, you may have to wait up to 24 hours for the spackling compound to dry completely.

Secondly, the size and depth of the hole or gap will also matter. Small holes or cracks will take only a few minutes to be filled with spackle. However, if you’re stuffing a larger area with the very same spackling compound, you will have to expect a much longer drying time.

Finally, different spackling compounds of different market brands have different dry durations. Some of them dry quickly, while others take a much longer time. Below are listed the main types of spackle available in the market, along with their drying time:  

  1. Standard Spackle: Standard spackle is the most basic form of spackle. It is a pre-mixed paste made of gypsum (calcium sulfate) and glue that can be applied directly to small to large drywall holes and cracks in the patched wall or ceiling. You simply have to allow the spackle to set and dry for at least two hours after implementation. Do go through the manufacturer’s instructions for a specific drying rate as well for confirmation as it might vary among brands.  
  2. Acrylic Spackle: Acrylic spackle is ideal for repairing multiple deep cuts, cracks, or fractures in brick, drywall, plaster, stone, and wood. It does not disintegrate or crack after drying, making it a unique choice for major renovations. You simply have to wait for this spackle type to dry for 2 to 4 hours.
  3. Epoxy Spackle: If you are dealing with repairing large-sized cracks, gaps, holes, fractures, or patches, epoxy spackle is an excellent choice. This is because the epoxy spackle has greater bonding strength and durability than other types of spackle. However, you will, unfortunately, have to wait for a whole 24 hours for this spackle to dry completely before you start painting.
  4. Vinyl Spackle: Similar to acrylic spackle, vinyl spackle is often used to fix brick, cement, drywall, rock, and wood as well. Due to its elastic polymers, this product can achieve adaptability easily. However, this sort of spackle requires about 2 to 5 hours to dry, based on the scale or size of the renovation and environmental conditions such as weather, climate, temperature, humidity, moisture, etc.
  5. Quick-Drying/Fast-Drying Spackle: As the name itself suggest, these spackle products can dry rapidly in a few minutes after implementation. They are typically used when a person does not have much time on their hands and is only working with minor drywall damage. The powder quick-dry spackle must be filled with water and mixed before application. This product category dries in minutes once applied. On the other hand, the premixed quick-dry spackle takes at least 30 minutes to dry.

Is it necessary to let spackle dry before painting?

Yes, it is necessary to let the spackling compound dry before painting, to let the area fixed with the spackle match with the rest of the wall. 

Fast-drying spackling compounds could take just a few minutes to dry. However, the normal spackle will take 1 to 2 hours to dry. 

As a whole, you can directly wait for 1 to 2 hours before sanding and another 24 hours before painting.

Is Fast-Drying Spackle Effective Enough?

Spackling comes in two varieties that dry quicker than other similar organic building compounds. To enhance drying time, both require a different chemical change. Let’s talk about the two:

  1. Fast-drying Powder Spackle: This spackle product is manufactured in powder form and is used as a quick-setting drywall compound. It must be mixed thoroughly with water before implementation. The water initiates a chemical change that shortens the drying duration. The reaction begins after all the water and powder are blended, and therefore, you have only a brief time before the spackle dries completely. These products are popular because they are a great alternative for rapid-fix tasks. They dry harder and faster than many other products, but they are more difficult to work with and need to be given a quick clean.
  2. Premixed fast-drying Spackle: When exposed to the air, this type of compound starts to dry. These types dry slower than the powder and water versions and may contain ingredients that impact the final product, like acrylic, epoxy, vinyl, etc.

Can you dry spackle with a heat gun?

Yes, you can use a heat gun to dry spackle, however, it is not advised. Using a heat gun on the spackling compound could be enticing, but can result in significantly irregular drying lines that are difficult to sand down. 

Here’s a video on using a heat gun: Using a Heat Gun to Dry Drywall Joint Compound. 

Heat will not assist the spackle much in drying. This could sabotage your healing attempts by drying the outer surface rather than the inner surface.

Instead, you could just set the compound to dry completely before actually implementing any form of refinishing.

Other than that you can make use of the quick-setting drywall compounds spoken above. They are sold in powder form and have drying durations of 20, 30, and 45 minutes.

How long would it take for the twenty-minute drywall mud to dry?

The mud dries faster or slower depending on several factors in your homes, such as air temperature, humidity, and moisture content. However, the twenty-minute drywall mud will usually dry up quickly after about fifteen minutes.

Can you quicken the drying duration of drywall mud?

While you cannot control the temperature outside, you can certainly try to raise the temperature in a drywalling room. Place and switch on the heater or furnace in the room to help the drywall dry faster. 

A hairdryer can also be used to clean a small patch of wall. Keep the hairdryer away from the affected area with holes or patches.

How can I speed up the drying time of the spackle?

With the help of an air conditioner or portable fans, you can speed up the drying time of the spackle. When dealing with spackle, air conditioning or fanning will optimize both the humidity and the airflow. Air conditioners or portable fans will eliminate moisture in the air, allowing the spackling to dry more quickly all thanks to the increased evaporation. 

Other than these, you can also add a coat of water-resistant paint and apply it before actually adding the spackle to prevent moisture from seeping into the region and making it hard to dry.

Will a fan aid in the drying of drywall mud?

The best relative humidity range for soothing drywall mud is from 20% to 40%. If you do not possess a dehumidifier, you could indeed prepare the room for mudding by implementing fans to achieve better air movement a few months, weeks, or days ahead of the repair or renovation project. The fans’ breeze will help decrease humidity levels.

Is it faster to dry drywall mud with heat or cold?

The right approach to drying the joint compound or drywall mud is to apply a little bit of heat. Warm, moist air speeds up the drying duration of drywall mud or joint compound in the same way that a dryer dries a huge pile of clothes faster on the “Hot” mode than on the “Cool” mode.

Is it possible to mud drywall when it’s too hot?

The ideal temperature before, during, and 48 hours after the finished drywall compound implementation is 55°F. You just have to confirm that the temperature isn’t dropping below 50°F or rising above 95°F.

It should be noted that the suitable temperatures for drywall will vary depending on the manufacturer and the type of ingredients mixed into it. So, do check the specifications on the product labels. 

Is thick spackle dryable?

Yes, if you’re using thick layers or coats of spackle, it is possible to make it dry. 

In most situations, one thin coating will dry more quickly than several thick ones. Nevertheless, the thicker you apply, the more drying duration you need to allow for the evaporation to occur.

How Many Coats of Spackle Are Required?

The number of coats of spackle required would be determined by the thickness of the ultimate coat. If you wish to get seamless and even finish, one or two thin coats are usually sufficient. 

However, if you want to obtain a more textured effect, the number of coats could very well increase based on how distinct each layer is.

How hot does drywall mud have to be to dry?

The suitable environmental factors for drying drywall mud are temperatures ranging from 65°F to 80°F and relative humidity levels ranging from 20% to 40%.

Is drywall mud affected by humidity?

When the water has evaporated from the wet material, the solid content of the mud remains. This helps form the finished hard surface. In humid weather or environments, the mud remains wet longer and absorbs more deeply into the face paper of the gypsum wallboard.

How do you reduce the level of humidity for renovation or repair projects with drywall mud? 

There are a few simple steps you can take to help limit the impact of humidity on drywall mud renovation or repair projects:

  • Reduce the amount of mud in each coat.
  • Do not thin the mud too much.
  • To thin the mud, use little to no water.
  • Space heaters powered by propane should not be used because they generate a lot of moisture.
  • Assist the evaporation process by providing sufficient ventilation and air passage.

What temperature is too high for drywall?

Thorough research has shown that permanent gypsum temperature problems occur mainly after temperatures exceed 176 °F. Dehydration occurs at temperatures ranging from 140°F to 176°F. However, research shows that they’ll most certainly be recovered to normal levels at this range and the drywall quality will not be compromised.

How does moisture control affect the drying time of spackle?

If your renovation or repair zone is moist or humid, it will be more difficult for the spackling compound to dry quickly without making a mess. To avoid this major issue, you must get yourself a moisture-resistant primer and use it before adding the spackle. This will help to hold the water away from the repair surface and prevent it from breaking or cracking.
