Gap Filling Adhesive
A gap filling adhesive is required where there is a gap between two materials that require sticking together. Adiseal is a high performance gap filling adhesive & sealant. It provides a high strength bond that has high gap fill, remains flexible, waterproof and solvent free. In this article we will also look at what is the best gap filling adhesive.
Why use a gap filling adhesive
When trying to stick two items together, sometimes the materials are not completely smooth. When the items are not smooth and when the items are pushed together, there will be places where the item surfaces will touch and places where there is a gap between the two item surfaces.
If using a glue or adhesive that does not have high gap fill, the bond will only be in the places where the two surfaces are close together. In the places where the gap is high, sufficient glue or adhesive will not remain between the gap. This will create a much weaker bond than a gap filling adhesive like Adiseal. There might even be places where the adhesive does not reach the other side leaving a hole.
Best gap filling adhesive
Adiseal has proven to be the strongest gap filling grab adhesive in an independent test. Ultimate Handyman carried out this independent test by testing the bond strength between wood and metal. The results of the test were surprising. Nothing came even close to the best product Adiseal. Watch the test in the video below.
Construction adhesive strength test
- Cleaned the metal sheet.
- Applied each construction adhesive from the different manufacturers to a piece of hardwood.
- Firmly pushed the wood down on the metal.
- Waited until each adhesive had cured.
- Used a hydraulic ram to break each construction adhesive bond.
- Measure at what pressure each bond broke at.
The best grab adhesive was Adiseal
“That is actually unbelievable!”Ultimate Handyman
- That Adiseal is phenomenal!
- That Adiseal is some stuff though, definitely need to get some of that bought!
- I instantly went looking for Adiseal!
- Need to get my hands on some of that to try out.
- Looks like a cracking product.
- Having used the two most expensive brands on numerous occasions, I’ll be trying out the others, especially the Adiseal.
- Adiseal certainly surprised me in this test!
- Fantastic tests. It’s unbelievable that Adiseal test with the hardwood.
Solvent free gap filling adhesive
There are numerous problems with adhesives that contain solvents. One of the main problems affects gap fill. Cheaper adhesives tend to be filled with solvents as it’s cheaper to manufacture. These adhesives cure as the solvent evaporates away from from product.
A disadvantage of solvent based adhesives when it comes to gap fill is the adhesive shrinks as it cures. This is because there is less active product in the cartridge. As the solvent based adhesive shrinks, there is a chance of the adhesive pulling away from the material it is stuck to. This will leave a weaker bond and less gap fill than a non solvent based adhesive like Adiseal. As Adiseal adhesive & sealant is a solvent free adhesive, it doesn’t shrink once applied.
The video below shows how a solvent based mastic adhesive shrinks whereas Adiseal, which is a solvent free adhesive, doesn’t shrink.

Gap filling grab adhesive
The Adiseal adhesive & sealant is a gap filling grab adhesive. For even higher grab, use the Adiseal Hi-Grab gap filling grab adhesive. The Hi-Grab product is designed to be very thick which gives it even higher gap fill and higher grab properties. For this reason, it requires a good quality sealant gun (caulking gun) to get the product out of the cartridge.
Gap filling glue
Adiglue has higher gap fill than traditional glues. It has a thicker gel formulation allowing it to remain in place in the gap whilst the glue dries. Adiglue is also solvent free. This means it does not shrink like other solvent based products. Adiglue activator can also be used to speed up the drying process.
The video below shows the thicker gel formulation of Adiglue.
Frequently asked questions about gap filling adhesive
In an independent test, Adiseal was found to be the best adhesive. It was a lot stronger than all the other products that were tested. As it is solvent free, it does not shrink or crack. It remains flexible and is waterproof as well.
In the UK, Adiseal can be purchased from stockists. For other countries Adiseal products can also be purchased from https://guglue.com
A gap filling adhesive is an adhesive that can fill a high gap between items that need sticking together. It will remain in place in the gap whilst it dries instead of running down.
