Regarding home improvement projects, Flex Seal is one of the most popular products on the market. But how long does Flex Seal last?
Flex Seal can last three to five years on average, depending on the surface and environment. Additionally, exposure to extreme temperatures, frequent use, and certain types of surfaces can reduce its lifespan.
In this article, we’ll take a closer look at how long Flex Seal lasts and offer tips for keeping your sealant looking great for years to come!
Introduction To Flex Seal
Flex Seal is a revolutionary product that helps protect and SEAL virtually anything from water damage. It’s an easy-to-use formula that forms an airtight, waterproof coating on various surfaces, including wood, metal, brick, concrete, and asphalt shingles.
There are different types of Flex Seal, including Flex Seal Liquid, which comes in a can and is used for larger projects such as roofs and chimneys. Flex seal liquid stretches up to 1000% of its original size and can be used in both wet and dry conditions.
Additionally, you can buy a Flex Seal Spray, which is great for SMALLER projects like sealing windows and doors.
There’s also Flex Tape, which you can use to patch holes or seal cracks in virtually any surface. Flex tape is 5 times thicker than regular duct tape and will stay put even in wet conditions.
Finally, Flex Shot is a silicone-based sealant that works on wet and dry surfaces. Flex shot is great for sealing cracks, small holes, and plumbing joints.
The Average Lifespan Of Flex Seal
When it comes to the average lifespan of Flex Seal, it can vary depending on the surface and environment. Generally speaking, Flex Seal lasts three to five years in normal conditions.
If you’re using it outdoors, you should expect a SHORTER life span due to exposure to harsh weather elements such as rain, snow, or extreme temperatures. In addition to environmental factors, certain types of SURFACES can also reduce the longevity of Flex Seal [1].
For example, porous surfaces like wood absorb more moisture than non-porous surfaces like plastic or metal. The extra moisture can cause the sealant to BREAK down faster over time.
Additionally, if you’re using Flex Seal for frequent repairs in high-traffic areas (such as a leaky roof), it’s likely to wear out QUICKER than in the regions that don’t experience as much use.
Factors That Affect the Lifespan Of Flex Seal
Here are a few factors that can affect the lifespan of Flex Seal products:
Exposure to Extreme Temperatures
Flex Seal is designed to WITHSTAND temperatures from -40°F (-40°C) to 160°F (71°C). However, if the temperature is outside of this range, it can cause the sealant to become brittle or even crack.
So if you’re using Flex Seal outdoors in extreme temperatures, consider using a DIFFERENT product or taking extra precautions to protect the sealant.
Frequent Use
Flex Seal is designed to withstand regular wear and tear, but if it’s exposed to TOO much usage in high-traffic areas, it can start to break down quicker than usual. So if you’re using the sealant in an area that experiences frequent use, check it regularly and REAPPLY Flex Seal if necessary.
Certain Surfaces
As mentioned earlier, porous surfaces can absorb MORE moisture than non-porous surfaces, reducing Flex Seal’s lifespan [2]. Use it on a non-porous surface such as metal, plastic, or glass to get the most out of your sealant.
Storage Conditions
To prolong the life of your Flex Seal, it’s essential to store it in a cool and dry place. If you live in an area with high humidity, keep the container tightly SEALED to prevent moisture from getting inside and affecting the sealant’s performance.
Preparation of the Surface
Properly preparing the surface before applying Flex Seal is key to ensuring it lasts as long as possible. Make sure to REMOVE any dirt, dust, or debris from the surface and use a damp cloth to wipe away any excess moisture that could seep into the sealant and reduce its lifespan.
Be sure to dry any wet surfaces before applying Flex Seal, as the sealant won’t adhere to a wet surface.
Application Method
When applying Flex Seal, use the correct method for the surface you’re working with. For example, if you’re using Flex Seal on a metal surface, use a brush or roller instead of spraying it on directly.
This will help ensure EVEN coverage and prevent any gaps from forming that could reduce the sealant’s longevity.
Pro Tip: Make sure to read the instructions on the Flex Seal container carefully before use and follow all safety guidelines.
How To Properly Maintain Flex Seal
Proper maintenance is key to extending the life of your Flex Seal. Here are a few tips for maintaining your sealant:
Check Regularly
Inspect the area where you applied the Flex Seal regularly for signs of wear or damage. If nePLY more sealant and make sure to use even pressure to ensure it’s sealed properly.
Protect from Weather
If you’re using Flex Seal outdoors, consider using a WATERPROOF material like plastic sheeting or tarps over the area to prevent water from seeping in and damaging the sealant.
Replace If Necessary
If your Flex Seal is no longer performing as it should, REPLACE it with a fresh coat. This will help ensure that the area is sealed correctly and prevent further damage from occurring.
Pro Tip: Apply Flex Seal in multiple thin coats instead of one thick coat for best results.
Alternatives To Using Flex Seal
If you’re looking for an alternative to Flex Seal, several other options are available. Take a look at some of the other sealants you can use to protect your surfaces and extend their life:
Silicone Sealant
Silicone sealant is an excellent choice for sealing and protecting surfaces against moisture, dirt, dust, or other external elements. This RESILIENT material can be applied to various surfaces, including metal, wood, plastic, glass, and more.
It forms a WATERPROOF barrier that creates an airtight seal while maintaining flexibility to expand and contract with temperature changes.
Additionally, silicone sealant is exceptionally DURABLE and resistant to UV rays, making it an ideal choice for outdoor applications. It will also last longer than other sealants, meaning you won’t have to replace it as often.
Rubberized Sealant
Rubberized coating sealant is another excellent option for protecting and sealing surfaces. It has a unique rubber-like consistency that allows it to be highly MALLEABLE, making it easy to apply and form around corners or irregular surfaces.
It also creates an airtight seal that effectively blocks moisture, dirt, dust, and other external elements. In addition, a rubberized sealant is highly DURABLE and resistant to UV light and extreme temperatures. This makes it an excellent choice for both indoor and outdoor applications.
It also has excellent ADHESION properties, meaning it will stay in place longer than other types of sealants while still easy to remove when necessary.
Epoxy Sealant
Epoxy sealant is another excellent option for sealing and protecting surfaces from moisture, dirt, dust, and other external elements. It forms an extremely STRONG bond with the surface it’s applied to, creating a waterproof barrier that will last for years.
An epoxy sealant is highly resistant to UV light, making it an excellent choice for outdoor applications. It’s also highly durable and can withstand EXTREME temperatures, making it an ideal choice for areas exposed to harsh weather conditions.
Finally, an epoxy sealant is easy to CLEAN with just soap and water, so you won’t have to worry about any harsh chemicals damaging your surfaces.
Urethane Sealant
A urethane sealant is an excellent option for sealing and protecting surfaces from moisture, dirt, dust, and other external elements. It forms a strong bond with the surface it’s applied to, creating an airtight seal that will LAST for years.
Additionally, urethane sealant is highly resistant to UV light and extreme temperatures, making it an ideal choice for OUTDOOR areas. It’s also easy to apply and can easily conform to irregular surfaces, allowing you to seal any area quickly and efficiently.
Finally, urethane sealant is HIGHLY durable, so you won’t have to worry about reapplying or replacing it often.
Butyl Sealant
Butyl sealant is an excellent choice for sealing and protecting surfaces from moisture, dirt, dust, and other external elements. This material is highly resistant to UV light and extreme temperatures, making it an ideal choice for outdoor use.
It’s also easy to apply and can easily CONFORM to irregular surfaces, allowing you to seal any area quickly and efficiently.
