Soapy Water Method 

To apply this method, you need a bucket with water, a sponge and dish soap that is free of bleach. Mix the dish soap with water and stir thoroughly until the solution produces soapy bubbles. Keep all electronics away from your working area. 

Make sure you inflate the mattress and place it in an open area where you can freely inspect it. You must be careful to avoid over-inflating the mattress since this can lead to larger holes or splitting of the seams. 

The next step is to thoroughly wet your sponge in the soapy water and slowly wipe the mattress in a systematic way. You can start from one end and work in a straight line to the other end and you can apply a bit of pressure to force air around the place that you are working on.

If you notice any bubble, then you would have identified a puncture which you should mark. You must perform this search process over the entire mattress and when you have identified the punctures, make sure that the mattress is completely dry before patching them.

Tissue Paper Method   

This method is simple since you only need a tissue paper to search for leaks on your mattress. You start by inflating the mattress and you must place it in a quiet environment so that you can carefully search for air leaks. Working from one end of the mattress, place the tissue on top of the mattress and apply some pressure to direct air to your working area. 

As you are pressing the mattress, carefully listen for any hissing sound while at the same time watching for any movement of the tissue. If there is a leak, then you can notice the movement of the tissue if the hole is large. You can also hear a hissing sound if the tissue passes over a puncture. Mark the hole and repeat the same process over the whole mattress. 

Other Methods

In case of torn seam leading to leaks, you can use hot glue but make sure that you do not touch the tip of the glue gun when it is hot. 

When you have cleaned the place around the hole on your mattress, cut the right size of the patch that can sufficiently cover the hole. When the patch is ready, you can apply it to the affected area. Some patches are self-adhesive but you may need to apply adhesive glue on other types of patches.

You can leave the weights for about eight or so hours to help create a strong bond. You can re-check the mattress for leaks when the patch has set.
