1. Big Gaps Foam Sealant: Ultimate Insulation Power!
I recently tried this spray foam for sealing gaps in my window seal and baseboards, and I must say it works great for big gaps. The color is not the best, but it is strong and gets the job done effectively. One thing to be cautious about is that it does expand, so make sure to use it sparingly to avoid making a mess. It can be difficult to remove from surfaces, so using gloves is highly recommended to prevent it from getting on your hands or the floor. Once you get used to using it, it becomes easier to handle.
In terms of cost, it is relatively cheap for sealing large gaps. However, for larger spaces, you might need to purchase a few cans as one may not be sufficient. I did notice that towards the end of using the foam, the straw tended to get clogged, making it difficult to extract all of the product. This could be something the company could improve upon.
I do want to emphasize the importance of using gloves with this foam as it is extremely sticky and difficult to remove. However, if you choose to go without gloves, using some 80 grit sandpaper can help remove it from your hands once it has dried.
Furthermore, if you are dealing with pests like rats, this foam is highly effective at preventing their entry. Unlike other foams that rats can chew through, this one provides a strong barrier that they cannot penetrate. However, be aware that it can be so effective that it may prevent you from opening your garage if applied excessively. I had to cut through the foam to open my garage, which was a bit inconvenient. But it just goes to show how well it works!
2. Tite Foam: Instant Seal For Gaps & Cracks
I recently used this product to create a vent for a portable AC exhaust hose in a challenging use case – a disgusting and ancient basement window. Overall, I found this product to be great and it accomplished exactly what I needed. However, there was a bit of a learning curve in applying it properly.
The process of using this product involved removing the old shattered glass window from the window frame and chipping out the old mortar to ensure a flush fit for the new panel. This proved to be a difficult task, but eventually, I was able to fit the vent panel into the metal framing fairly well.
I started applying the foam from the outside, and while sealing the gap at the bottom went smoothly, I encountered difficulties when sealing along the right side. The foam would roll off the front of the vent panel, creating a mess and compromising the seal. Similar challenges were faced when sealing along the top and left side.
To rectify these issues, I had to remove the excess foam with my hands, which was a messy process. Then, I decided to start sealing from the inside, hoping to push the panel into place for a better seal and fit. However, I had to work quickly as the foam dried fast. Unfortunately, my hands were covered in the foam, making it challenging to proceed. After cleaning my hands, I discovered the correct technique for using this product.
The key was to apply minimal force on the trigger and spray the foam into a gap. The foam would then expand to fill the gap and create adhesion on all sides, preventing it from sliding or glooping up. I realized that I should have been doing this from the start, and felt foolish for not figuring it out earlier.
With this new understanding, I successfully completed the sealing process both inside and outside. The end result was as good as I could have hoped for, considering my lack of experience in such tasks. While I made a mess of my hands, washing with regular dish soap removed most of the adhesive, and within half a day, it was almost completely gone. It is advisable to wear gloves to avoid this issue.
3. Red Devil Foam & Fill: Small Gap Savior
I recently had the opportunity to try out this product, and I have a few important facts to share. First and foremost, it is important to note that this product is extremely sticky. If you happen to get it on your hands, arms, or even in your hair, I recommend using coconut oil to remove it. The key is to remove it as quickly as possible, as it becomes harder to remove once it dries. Additionally, it is important to work quickly when using this product, as it has a tendency to swell up quite a bit. During my first application, I had to remove the excess material up to 7 times before achieving the desired result. However, I have since learned to spray faster and wait for it to dry before cutting off the excess with a razor blade or knife.
If you do not have coconut oil readily available, I would suggest using any other type of oil to aid in the removal process. It is worth mentioning that cleaning up the mess after the product has completely dried is much easier and less time-consuming.
Now, let's talk about the main reason I purchased this product – to lower my electricity and gas bills. My house and my daughter's house are the exact same dimensions and design. However, due to my house being well-sealed and efficiently insulated, I am able to run my air conditioner at 67°F or even lower. On the other hand, my daughter struggles to get her air conditioner to reach a comfortable 72°F during the summer months. The meticulous sealing of every nook and cranny in my house has proven to be a money-saving technique. Living in Louisiana, where the humidity can make it feel like 110°F on an average summer day, I do not shy away from using my air conditioning. In fact, I treat myself to lots and lots of air conditioning. Surprisingly, my electricity bill for this month was only $43, despite running the pump to my swimming pool and using 12 Flowtron mosquito zappers throughout the night. In contrast, my daughter's bill, without a pool or bug lights, was $180, and her house always feels warm.
Part of my strategy to keep my electricity bill low is to take advantage of the lower rates during the night. I make my house as cold as possible before going to bed, and as the sun starts to rise, I turn off the air conditioning completely. I only run the air conditioner for about half an hour during midday, and surprisingly, my house stays cold throughout the day.
Now, onto the product itself. I have used similar products in the past, although not this particular brand. It is important to note that when using this product, you must wear protective eye gear and gloves. It is not easy to remove, and you definitely do not want it to come into contact with your skin. Despite this precaution, I found the product to be relatively easy to use. It expands to double the size of the line you put out, which is a great feature. In my case, I needed to fill an area on an outside wall in the basement where the vents for my new gas stove went outside. Being able to trim the excess material was a great advantage.
The only reason I gave this product 3 stars for value is that it was a bit pricey for my budget. However, considering the potential energy savings and the effectiveness of the product, I believe it is worth the investment.

This will allow you to easily screw the nozzle onto the can without worrying about the insulation spraying out. By following this method, you can avoid product wastage and frustration during assembly.
Creating a Dress Form for Sewists:
For those interested in using this product to create a dress form, the process can be quite effective when done correctly. Start by covering the desired body part with body oil, followed by layers of newspaper and masking tape. To create a form for the lower body, cut down the side of the full leg and carefully remove yourself from the form. Use duct tape to tighten any loose spots and ensure a secure structure.
When applying the insulation product inside the form, be aware that it expands significantly, roughly three times its original size. It is important to avoid overfilling the form, as excessive expansion can cause seams to burst. To prevent this, tightly seal the seams with duct tape after applying the insulation. Additionally, it is recommended to leave openings at the ankle or leg to allow for expansion.
By following these steps, you can create a dress form for pants fitting or upper body garments. For detailed tutorials, Threads Magazine offers a comprehensive guide for the upper body, specifically using the foam insulation method.
