Loctite IDH# 2474240 Review

I have tried different adhesives, but Loctite PL 300 Foamboard VOC Adhesive is one of the best.

I used it to attach insulation sheets to my attic walls and ceiling, and I could use one tube for both jobs. The adhesive sticks tight, which is why it stays around for a very long time.

One significant quality of it is the strong, durable bond it makes to all kinds of foam board insulation products, as well as because it’s made of latex, you can use it on anything from foam board to wood to metal without worrying about whether or not it’ll ruin them.

I love how it can be used in so many different ways!

It’s quick and easy to use, has a high grab (which means you don’t need any fasteners) and sets in just 20 minutes. This product cures fully in 24 hours, ensuring that your project will be strong enough to last for years!

Resistant to the effects of weather and water, it’s an appropriate adhesive for use outside on projects where these variables may present a problem.

Compared to other adhesives, this adhesive has a more smooth texture and a longer shelf life.

Gorilla Clear Glue Review

I love the Gorilla Clear Glue Adhesive because it can bond various materials and is strong. No matter what you want to join: wood, metal, ceramic, or foam board. It bonds it all!

The glue is clear and does not foam, making it appropriate for many projects. It is water-resistant too, so you do not have to worry about spills or rain destroying your work.

I applied it to my glass table top, which had a broken corner, and the bond is extremely strong! The glue has not given out over time, even after daily use.

The only drawback is that it can take up to 24 hours to cure, but this is a small sacrifice to make for such an excellent product! This glue has been my adhesive of choice since I first discovered it. The word winner perfectly encapsulates it!

Gorilla Clear Glue Pros And Cons


  • Bonds virtually everything
  • Water-resistant
  • Incredibly strong


  • It can be difficult to remove once dried

What You Should Know Before Buying

  1. Adhesives come in different forms, so you’ll need to decide which type is best for your project. 
  2. You’ll also need to consider the thickness of the adhesive and the size of the area you’re trying to cover. 
  3. Make sure to read the adhesive instructions carefully before starting your project. 
  4. It’s also essential to test the adhesive on a small area before you commit to using it on your entire project. 
  5. Once you’ve decided on an adhesive, follow the manufacturer’s instructions for application and curing times.

What Happens If The Adhesive Doesn’t Stick?

If the adhesive doesn’t stick, the foam board will start to come off of the metal. This can be a big problem if you use the foam board for insulation or soundproofing. 

The best way to avoid this problem is to ensure you buy the right adhesive. Here are some tips:

  1. Ensure you get an adhesive specifically designed for foam board to metal. 
  2. Check the labels and ensure the adhesive will work with your metal. 
  3. Follow the instructions on the label carefully. 
  4. If possible, test the adhesive on a small area before you commit to using it on your project.

Things To Look Out For When Buying Foam Board to Metal Adhesive

When you’re looking to buy adhesive for foam board to metal, there are a few things you’ll want to keep in mind. 

First, you’ll want to ensure that the adhesive is of good quality. This means it should be strong and durable to hold the foam board and metal together securely. 

Second, you’ll want to ensure that the adhesive is easy to apply. You don’t want to struggle to apply foam board to metal glue, as this can cause frustration and damage the foam board or metal. 

Third, you’ll want to make sure that the adhesive dries quickly. You don’t want to have to wait around for hours or even days for the adhesive to dry completely.

If it takes too long, you might have problems such as rusting. The last thing you want is an issue like that!

So when buying adhesive for foam board to metal, consider these three points: high-quality, easy application, and quick drying time.

With these three qualities in mind, the adhesive will work well on your project!
