How Long Does Caulk Take To Dry? – Step By Step Guide
There is nothing better than fresh caulk, it’s a waterproof filler and sealer, used mainly in house construction and repairs. For example, if you want to give your bathroom a clean and bright look, like if something is broken, like a bathtub or has a leak or gaps then the caulk is the product you should go for.
Moisture can over time consume the best sealant and allow mold and mildew to grow. But instead of bleaching and scrubbing, using caulk is the smart move. When questions like “how long does caulk take to dry?” popping up in your mind, you can consider our research regarding the same. The answer to this question is 12 hours, but if you don’t give it time to dry it can easily wash away making all your hard work go in vain.
Therefore, to know more about caulk and its uses, keep reading the article.
Factors That Affect Drying Times
Remember the most important thing about caulk, there is a difference between ‘dry time’ and ‘cure time’. Most products will dry within 30 minutes of applying but that doesn’t mean it fully cures because after applying caulk you need days for it to completely cure.
There are factors mentioned in the following while determining how long does caulk take to dry:
1st Factor : Formulas Take Time
You will find silicone caulks advertised as ‘fast drying’ claiming a one-hour dry time. I recommend you to do your research while you plan your project based on this information.
It depends on a narrow range of temperatures and humanity levels. Products like this need at least 12 to 13 hours for drying and days to completely cure. In the case of a latex-based product, it needs 24 hours to fully cure. Polyurethane caulks take 10 days to cure.
2nd Factor: Some Caulks Are To Cure Beneath A Coat Of Paint
If you want to paint over caulk, like if there is a tile molding situation in your restroom that separates tiled backsplash from your painted wall. Then caulk should be applied to cure under the coat of paint.
After putting the caulk you can apply your paint within 30 minutes easily, but if it’s a polyurethane caulk you must wait for 7 to 10 days until the surface you applied the caulk on is ready and fully cured before painting.
Whatever formulae you use make sure you have gone through the instructions properly, as different manufacturers use different formulae with methods for application and drying.
3rd Factor: Not All Caulks Responses In The Same Way
If you are applying acrylic latex-based caulk then you need to wait till the water evaporates from the material. To fasten up the drying process you can put a table fan in the room by turning it towards it.
Silicone caulks need moisture to dry and cure. Go for a humidifier, it will help. Polyurethane caulk should not come in contact with direct water and added moisture for 3 days of a week.
4th Factor: Temperature Plays A Vital Role In The Drying Time Of Caulk
The perfect temperature for applying and curing caulk is in the middle of 40 to 80 degrees Fahrenheit. Therefore adjust your thermostat carefully and accordingly. If you want to work with caulk in winter when the air is drier it’s going to take longer to cure.
Make sure you don’t add heat to it because it will soften and melt the silicone. Latex on the other hand will freeze in too much cold. It will lack enough moisture for a proper cure, therefore don’t apply the caulk in freezing cold weather.
5th Factor: Caulk Will Always Give The Best Result
Old silicone and latex caulk can become cheap quality and will not cure fully even in a sealed tube. Companies generally put an expiration date on the tube for you to understand the given time for use.
So if you find a caulk tube somewhere in your house don’t use it as it will not give any result. Buy a fresh one, check the manufacture date first and to test, use it on a solid surface. If it’s fresh it will form a firm skin within 30 minutes of applying.
Remember Polyurethane caulk should be used within 12 months of the manufacture date.
Here you go with the 5 factors that matter in drying and curing a caulk. It gives an idea about how long does caulk take to dry.
Now let’s move forward into knowing different types of caulk and their curing times.
Silicone Caulk
Silicone caulks work the best when applied to glass, ceramic, and metal. It sticks easily with smooth and impenetrable surfaces.
It creates a stretchy yet long-lasting bond. You can find silicone caulks with antimicrobial additives which keep germs away from bathrooms and kitchens.
Acrylic Latex Caulks
If you want to fill gaps and joints in wood then go for Acrylic Latex Caulks. It will work best on the areas that will get colored and are exposed to water, not even a little amount.
Why take this measurement because acrylic latex caulk shrinks and crack over time leaving the surface exposed to water damage. Some acrylic latex caulks now have silicone additives in them to push waterproofness, durability, and flexibility. It makes them appropriate to get used in bathtubs and sinks as well.
Polyurethane Caulks
It is a caulk that is growing in popularity. Especially for seals of windows and outdoor uses. Polyurethane has greater elasticity, creates a damp-proof, repels dirt, and is paintable.
It takes a long time to fully cure, longer than the other two. There you go with the section ‘different types of caulks’ under the article how long does caulk take to dry.
People often ask a lot of questions about how long does caulk take to dry but we have one question that is frequently asked.
What Happens If The Caulk Gets Wet Before The Cure?
Well, if the caulk gets wet before the time of cure, then the formulae won’t give you the result you were waiting for.
It can either take longer than expected or can completely get destroyed. In that case, you will have no other choice than to start your project again.
How to Get Your Caulk to Dry Faster?
You cannot easily dry your caulk since there is no specific way to speed up the process. The speed of drying or the drying time depends on the formula of the caulk and the type of caulk you use. But, there are processes for setting up your space that will help the caulk dry fast and efficiently. But, first, we recommend reading your product label very carefully and following any instructions provided there.
Here are some tips that you can follow –
Do Not Use a Hair Dryer
You are mistaken if you think using a hair dryer can dry the caulk. Direct heat often softens or melts the silicone, which eventually prevents it from drying. If you really want the caulk to dry up faster, then you need to ensure that it remains in temperature between 40 degrees to 80 degrees Fahrenheit. So, say no to hair dryers.
Avoid Water
This is not a tip to hasten the drying process for your caulk. But following this tip will allow you to keep the cycle of caulk drying steady. Avoiding water to disrupt the caulk’s formula is probably the best way to complete it without any problem. Also, letting water disrupt the process of drying the caulk. In the end, you may end up redoing the process all over again.
Do Not Use Extreme Cold
Yes, having water around does make caulk melt. But if you want the caulk to dry effectively, it must have some air with the necessary level of moisture in it. If the caulk is in extreme cold, it will freeze, making the caulk grow hard and lacking the humidity needed to adjust properly. Moisture that most caulk needs to cure. So extreme cold is also not too good for caulks.
Use Humidifier
Silicone can easily cure moisture in the air. You can use a humidifier to create perfect weather conditions for the caulks. If you use a humidifier around the caulks, it will create an ideal condition for the caulks to dry. This condition will not work for acrylic latex, though. So, keep that in mind.
Turn Of The Heat
If you have a room heater, then the caulk will not dry so fast. The room heater dries the air in the room, making the process of drying the caulk longer and more difficult.
Use A Fan
If you have acrylic latex, then I would suggest using a fan. Acrylic latex dries when the water evaporates from the caulks. So, if you want to speed up the process of drying the caulk, then you might as well use a fan. That will surely speed up the curing process.
