Unlike conventional caulk, non-shrink ones have the least shrinkage or no shrinkage at all, therefore creating a more solid seal. However, finding the best non-shrink caulk isn’t an easy job.
Most of the caulks available on the market advertise to have shrinkage prevention, so figuring out which caulk will back their words up is a tough job.
Moreover, to ensure you are spending your money on the right non-shrink caulk, you also must consider some factors. In this article, I’ll help you out with this matter.

Finalizing the top 3 non-shrink caulk wasn’t an easy job. There were so many great options available on the market, and after thorough research, I have come up with a list of my top 3 non-shrink caulk.
So, let’s see what each of these caulks can offer you in terms of sealing and what will be the best choice for you, depending on your requirement.
Sashco Big Stretch Caulk
The main reason why Sashco has earned the top spot on my list is because of the durability it possesses.
No matter which job you throw at this amazing caulk, it’s completely preventive of any kind of cracking and peeling.
The main purpose of Bug Stretch caulk was to use it in various indoor and outdoor projects like doors, windows, vents, etc.
It means the manufacturer had put enough attention to the product to withstand the constant abuses of these project parts.
I loved the extreme elasticity of Big Stretch caulk. No matter how much movement there is, the caulk will be there to handle that effortlessly.
The surface compatibility of Sashco is exceptionally well too. Whether it’s plastic, wood, or concrete, the caulk just sits there perfectly. Due to the UV resistance, outdoor use isn’t a big deal for this caulk either.
Whether it’s carpenters or interior workers, Sashco Big Stretch is an excellent choice for any type of sealing activity. Big Stretch is manufactured in the USA, so the price is just a few bucks more than other options.
However, that also ensures the performance at the same time. Though it doesn’t work great against water, the rest of its features are enough to make it a great deal.
Tips: The packaging recommends you wait for one week to cure before latex paint. However, giving the caulk 48 hours should be enough.
Permatex Black Silicone Adhesive Sealant
The next item I have on my list is an adhesive sealant. However, it does the same job as a non-shrink caulk and sometimes does it even better.
The first thing I noticed about this sealant is its surface versatility.
Plastic, metal, glass, fabrics, or any other surface you name, you can easily use Permatex Black Silicon adhesive sealant on it.
That’s why this sealant can come in handy for a wide variety of people, like DIYers, housebuilders, car mechanics, and many more.
Unlike the Big Stretch I discussed above, Permatex adhesive sealant can easily withstand water.
However, the elasticity might not be superior to Big Stretch.
So, you probably want to keep that in mind while applying the sealant. If you are in a hurry to complete a project, this sealant can be a helping hand by curing fast.
With proper exposure to moisture in the air, Permatex sealant can easily cure within 24 hours.
Lastly, I would like to address the extreme temperature resistance of this Permatex sealant. Anything between the range of -59°C To 232°C, this sealant can hold up pretty easily.
Tips: The adhesive sealant comes out pretty thin out of the tube. Creating a mess by suddenly pressing the tube is common among users. You can use a Q tip and napkin to apply evenly for the best application. Otherwise, it can stick to your hand or any other surface you work on.
Tower Sealants Tower Tech 2 Acrylic Urethane Caulk sealant
The last option I have brought is the Tower Sealant. Now, this brand might be less familiar within the community, but the sheer quality earned this caulk a place on my list.
This Tower Tech 2 caulk sealant is different from the rest of the competition in its manufacturing formula. This sealant is completely acrylic-based.
Being acrylic-based brings certain benefits to the table that other caulks don’t offer.
For starters, acrylic urethane sealants are paintable. So, no matter where you apply it, you can just paint on top and make the sealant merge into the surface.
If you are someone concerned about environmental effects, there is good news too. Acrylic is way less toxic and environment-friendly compared to other materials.
For being odorless, you can use Tower Tech 2 sealant anywhere you want in your household. According to users, though there is no exact fire rating from the manufacturer, it can withstand high temperatures.
As far as surface compatibility is concerned, Power Tech 2 caulk sealants tend to fall behind a little. According to the manufacturer, this sealant is only compatible with vinyl, wood, and aluminum.
Except for this matter, this is a solid non, shrink caulk you should spend your money on.
Tips: Tower Tech 2 Acrylic Urethane Caulk sealant is paintable. But you have to give enough time to dry and cure, as the curing happens after drying.
Points To Remember Finding The Perfect Non-Shrink Caulk
Even with a simple product like caulk, there is a lot of this to consider if you want the best result. Remembering the following points while buying a non-shrink caulk will guide you to the product you should purchase.
Caulks are manufactured based on different materials. Each of these materials also has other characteristics. So you have to decide the formula based on the type of your project.
For example, if you want to paint, go for acrylic caulk. On the other hand, if you wish durability and flexibility, go for silicon-based caulks.
Non-shrink caulks typically comes in cylinder cartridges or squeeze tubes. Deepening on your convenience and precision requirement, choose the packaging carefully.
For large caulking projects requiring precision, go for cylinder cartridges. For smaller jobs, squeeze tubes should suffice.
- Water resistance
If you are planning to apply the non-shrink caulk on a surface with continuous water contact, pick a caulk that has water resistance.
While lots of good options are great in quality, they don’t offer any sort of water resistance. So, before making the purchase, keep this matter in mind.
- Surface compatibility
Every caulk on the market is compatible with a different group of surfaces. While there are a few commonly compatible surfaces, like vinyl or aluminum, other surfaces may vary.
That’s why make sure the caulk you purchase is compatible with the surface you’ll apply on.
Tat’s wrap for today. I hope my review of the best non-shrink caulk will come in handy for you going forward. I tried to cover different types of caulks in my list, so there is something for everyone.
If you are still confused, you can just try to follow the points I mentioned above. Hopefully, you’ll get the caulk you have been looking for.
