Caulk is an essential part of many construction and renovation projects, but it can also be used in freezer applications to great effect. Specialty caulks are a useful tool for sealing a commercial freezer or controlled environment space. Caulking is designed specifically with durability and flexibility as the priority, so that you can be sure your job looks good, lasts long, and continues to work.
Whether you're a contractor installing a new freezer for a restaurant, or an owner dealing with maintenance issues for their own commercial freezer or cold storage unit, specialty caulks will get the job done. Using the right sealant can make all the difference when it comes to creating air-tight seals that keep your food safe and secure from extreme temperatures and moisture.
In this article, we will discuss the different types of caulks available, and why silicone caulk is the best choice for freezer applications. There are also helpful tips on how to apply freezer caulk successfully.
Caulk is a type of sealant that is used in many commercial and residential applications, like kitchens, bathrooms, window frames, and more. As a professional contractor, restaurant owner, or grocery store owner, it's important to understand the power of caulking.
Reasons to caulk:
In short, caulking is an essential tool for any business in helping maintain building integrity, as well as appearing aesthetically appealing for customers.
Applying and smoothing out acrylic latex caulks is a breeze. They are the only type of sealant that can be cleaned with water. If you want an acrylic latex caulk that will hold up well and stay flexible, look for versions labeled siliconized or plus silicone.
Poly caulks are typically more durable than other types of sealants, which makes them ideal for use in high-traffic areas or locations that experience drastic temperature changes.
Hybrid caulks usually include silicone and polyurethane for the best adhesion, flexibility, and durability possible. They're more attractive to apply than polyurethane, but not as clean looking as acrylic latex. However, in applications like commercial walk-in freezers, this is usually not an issue.
Caulks used in freezers are subjected to severe temperature extremes, especially cold. Standard exterior or interior silicone-based caulks are generally rated for temperatures between 20 degrees and 120 degrees Fahrenheit.
While a freezer will never reach the high end of these extremes, it will regularly exceed the lower level. A typical walk-in freezer used in commercial applications will maintain a temperature between -10 degrees and 0 degrees Fahrenheit (-23.33 to -18 degrees Celsius).
If the temperature is below 40 degrees, many caulks will lose their adhesive qualities. If you're using caulk in frigid temperatures, you will need to get a type of low-temperature caulk that contains silicone or rubber.
Although latex caulking is best applied in temperate weather between 40 and 80 degrees Fahrenheit, other types of caulk can be used even in frigid conditions. In fact, high-performance caulks with a rubber or silicone base are less likely to freeze than their latex counterparts.
Polyurethane sealers are an effective way to protect various surfaces, including wood, metal, plastic, masonry, aluminum, and stucco. They provide a waterproof and flexible solution that can withstand any temperature conditions. They are ideal for sealing gaps and joints on both the exterior and interior of structures - including walk-in freezers.
Dynatrol I-XL is a moisture-curing, single-component non-sag polyurethane sealant that is perfect for sealing joints between diverse materials with varying coefficients of expansion and contraction. Dynatrol I-XL can be used on both porous and nonporous surfaces. Once fully cured, it forms a low modulus rubber with amazing adhesion and can accommodate joint movement of up to 50% of the original joint width. Some more benefits of this product include:
