Noticed a rip in your foam mattress? Do you want to turn two into one larger bed? Learn how to safely glue foam together.

Glueing a foam mattress requires a few simple steps. The foam must be free of dirt and debris. The right glue and amount of pressure must also be applied.

These days, fixing foam can be done by anyone with the right tools. Here’s everything you need to know!


How To Glue Foam Together For A DIY Mattress Project

There are two main reasons why a handy person such as yourself would wish to glue a foam mattress. There might be tears in the memory foam. You might also need a bigger bed and decide to foam two single foam mattresses together. In the past, glueing foam together had really bad consequences. The glue either did not work or dissolved the foam, causing more damage. 

For the best success, you need to follow a few simple steps.

  1. Clean the foam.
  2. Choose the correct glue.
  3. Apply the glue correctly.
  4. Apply correct and timely pressure.
  5. Allow the foam and glue to set properly.

How To Clean A Foam Mattress

Before glueing foam, it is essential that the surface is clean and free of debris. If anything remains behind, like dust, tiny bits of foam or moisture, the integrity of the glue will be compromised. Either the glue will fail immediately or a few days down the line. 

Your new mattress needs a protector! We have a good article that explains how to make your own mattress protector at home.

How Do I Clean A Foam Mattress?

The proper way takes a little time but you will thank yourself later when the glue sticks! As a bonus, you will also enjoy a clean and odourless mattress. Here are the basic steps to follow.

  • Strip off all the bedding. Those need to go into the wash.
  • Treat all the stains by spraying a mixture on them (equal parts white vinegar and water). Do not drench the spots. 
  • After leaving the vinegar solution for about half an hour, sprinkle a lot of baking soda powder on the areas to soak up the moisture and the odours. 
  • Next, focus on the rips on the sides that you plan on glueing together.
  • Brush the tear or surfaces with a brush to wipe away debris and bits of sponge. 
  • Use a commercial spray if you want to do a deep cleaning of the areas.
  • Always remember to work in a well-ventilated area.

Can You Recommend Extra Reading To Clean My Mattress?

If you really want to do a thorough cleaning job, we wrote several articles to ensure that your mattress is spanking fresh. Also, remember to make sure that your foam is completely dry before you glue anything. If any moisture remains behind, then mould and mildew will develop. These goobers are dangerous to one’s health, especially to those with asthma or allergies. 

How To Choose The Correct Glue

There are countless glue products for foam. But which are the best? One must think in terms of efficiency and results. In other words, you do not want to spend hours applying the glue and the stuff must actually work! 

It’s best to do your research to find a brand that you are satisfied with. But we do recommend choosing an aerosol variety. This allows you to spray the glue onto the surfaces. Needless to say, this saves a ton of time if you want to glue two large pieces together but do not have time to waste. Nothing is worse than applying glue and watching it go dry because you cannot work fast enough. An aerosol glue will prevent this from happening. 

Also, choose a glue product that is specifically designed for glue. Never use glue meant for something else because it will either fail to work or dissolve the foam. 

We definitely do not recommend using a hot glue gun! But here’s an interesting DIY project for your gun. Learn how to patch an air mattress with a hot glue gun.

How To Apply The Glue Correctly

When it comes to using the glue, keep two things in mind – correct application and your own personal safety. Most glues today are still packed with chemicals that are not entirely safe to inhale. So wear a mask and don’t allow pets or kids to stand nearby while you work. 

To apply the glue, read the instructions on the back of the box or aerosol can. These must be followed down to the last letter. A good product will explain how to use it, how long it takes to work, what not to do, and how to apply the correct pressure to seal the foam. If you are glueing together two large slabs, you might need the help of another person to apply enough “push” to keep the slabs together long enough for the glue to take hold.

No matter what type of mattress you use, a flat sheet that has a life of its own can disrupt a good night’s sleep. Learn how to keep a flat sheet tucked in by making hospital corners.

Allow The Glue Some Time To Set Properly

The instructions should also reveal how long the foam must be left alone before you can sleep on it again. Never rush this timeline, even if you do not have another mattress. If that is the case, then don’t worry. There are plenty of ways to get a good night’s rest without a bed! Don’t believe it? Then hop on over to our popular article that reveals 5 ways to make a comfortable bed without a mattress!

Allow the mattress more time than the instructions suggest. This is to get rid of the glue smell which, needless to say, is not a pleasant aroma when you are trying to fall asleep. 


A Quick Summary On How To Glue Foam Mattresses

  • DIY masters have two main reasons when they want to glue a foam mattress – to fix tears or to make two smaller beds into a single large mattress.
  • A few simple steps will ensure success.
  • One of the most important preparations is to clean and dry the mattress beforehand.
  • Using the right glue and pressure also helps foam to stick together.
