What is the best adhesive & sealant?
The best grab adhesive, strongest adhesive & flexible adhesive is this particular product from this particular manufacturer? What is the best construction sealant to repair a leaking gutter? With so many different construction adhesives & construction sealants available from different manufacturers, it can be quite difficult to find the best product for a particular job. Adiseal is a multipurpose product that outperforms dedicated products for particular jobs.
Best grab adhesive?
Manufacturers will claim their product is the best grab adhesive, No.1 product, strongest adhesive, most flexible adhesive, top construction adhesive or greatest construction sealant. In reality only one product can be the best & strongest. With so many different products claiming to be the best, the only way to find out is to get them independently tested against each other.
Grab adhesive strength test
To find the best grab adhesive, Ultimate Handyman carried out several independent adhesive tests. The results were quite surprising, where Adiseal literally blew away the competition with record breaking strength.
To carry out the grab adhesive strength test, Ultimate Handyman applied each grab adhesive between hardwood & metal. They were then left for few days to allow the adhesives to cure. After they had cured, a hydraulic ram was used to break the adhesive bond between the hardwood & metal, measuring the pressure at which each bond broke.
The strongest adhesive was easily Adiseal
Adiseal came top from the products tested. It was way stronger than all the other competitor products & was over 3 times stronger than the nearest competitor. In fact it was so good that the screws holding the test rig down started to rip out and the hydraulic ram seal broke forcing the test on Adiseal to be stopped. Adiseal was too strong for even the test rig & easily the strongest adhesive by far.
The bond between the hardwood to metal for Adiseal still did not break at over 3123 psi, whereas all the other grab adhesives broke at 1115 psi or less. The results are in the chart below showing Adiseal is one seriously strong grab adhesive.
The test results of the best grab adhesive

What about other grab adhesives?
Ultimate Handyman has carried out a number of tests over the years, the results of which are on his YouTube channel. Our old formula Adiseal was also tested along with some of these other products, including products from Soudal, Geocel & C-Tec.
Adiseal vs CT1
It would be easy for any manufacturer to claim that their own construction adhesive & sealant is the No.1 product and better than competitor products, but does reality actually match the manufacturers marketing hype. For this reason rather than us just say Adiseal is better than CT1, we say let us prove it to you how Adiseal is better than CT1 adhesive & sealant.
The latest formula of Adiseal is much better & lower priced than CT1 & BT1. For further details & proof on how Adiseal is better than CT1 & BT1, please send us an email. As we can prove Adiseal is better than CT1, for trades people in the UK we are offering a free tube of Adiseal White so you can test yourself how Adiseal is better than CT1 & BT1. See the offer page for more details. We say rather than listen to manufacturers marketing hype, to find out how Adiseal is better than CT1 & BT1 is to test it yourself.
Some manufacturers claim their product is 360% stronger than competitor products but is this bold claim really true without any evidence shown to back it up? Without the evidence to back it up, it’s just manufacturers marketing hype.
Adiseal has proved to be the record breaking strongest adhesive in an independent adhesive strength test. Adiseal was way ahead of the competition in the independent test which competitor products claiming to be No.1 can’t do.
Why pay more for a brand name when it’s performance that matters. We say separate hype from reality.
Adiseal strongest again in metal to metal adhesive strength test
The impressive Adiseal was also the strongest when Ultimate Handyman carried out a similar adhesive strength test between metal to metal. Finishing top again, Adiseal is not just good but the best grab adhesive by far. With Adiseal being such a great adhesive, is it any good as a sealant?
What is the best sealant?
With Adiseal proving it’s the best grab adhesive by an independent test, what is it like as a sealant?
Best mould resistant sealant test
To find out what is the best construction sealant, we carried out several tests including a mould resistance test. The mould resistance test was carried out by applying sealants from different manufacturers inside new clean plastic cups then filling the cups half way with tap water. Each cup was then covered and kept in the same conditions, so as to be fair to all the products being tested. As can be seen in the image, the best sealant was Adiseal again where it had the strongest mould resistance from the sealants tested.
Mould resistance test result
In the above image even after 90 days of being submerged in the same tap water, both the sealant & water are still very clear in the Adiseal cup compared to other products. One of the competitors product being tested, claimed to be the No.1 adhesive and sealant. This other product which is more expensive than Adiseal, didn’t perform as well as Adiseal in the mould resistance test. Unlike the competition Adiseal doesn’t just claim to be the No.1 construction sealant & construction adhesive, Adiseal can prove it.
As well as Adiseal having the strongest mould resistance, Adiseal also seals instantly, works in the wet & even underwater.
Are you looking for a clear sealant?
Adiseal Ultra Clear sealant & adhesive is one very clear sealant. Other construction sealants might say clear on the tube but when you apply them they are instead cloudy or have coloured tint. Cheaper silicone sealants tend to be very cloudy, almost white in colour when you apply them instead of being clear.
Adiseal has strongest colour retention
As well as Adiseal construction sealant having the strongest mould resistance, Adiseal also has the strongest colour retention even underwater. The competitor product in the image above is more expensive than Adiseal and it also claims to be the No.1 construction adhesive & construction sealant. As can be seen in the image above, this competitors new clear product has turned white when in contact with water.
Colour retention test
The colour retention test was carried out with a number of different clear sealants & adhesives from different manufacturers. To do this, each product was applied inside new clean plastic cups, filled half way with water, covered the cups & then kept them in the same conditions.
Adiseal top in colour retention test
Adiseal was the only product to stay clear in & above the water. The worst performer was the new clear product from the competitor claiming to be the No.1 construction adhesive & construction sealant. It was the only product to turn white completely, even the half that was above the water. In fact their old formula clear sealant & adhesive performed better as it turned white in the water only.
Why pay more for a brand name when it’s performance that matters. We say separate hype from reality.
Separate Hype From Reality
It’s easy for a manufacturer to claim to have the No.1 construction adhesive or construction sealant, but the only way to prove it is to have the product independently tested against the competition. Adiseal has actually proven it’s the best grab adhesive & sealant. Some of our competitors claiming to be No.1 fail to match their hype even when they are more expensive than Adiseal.
In a previous test by Ultimate Handyman to find out the best grab adhesive, one competitor claiming to be the No.1 adhesive & sealant finished 8th out of 10. We say separate hype from reality and don’t fall for manufacturers marketing hype. Why pay more for brand names when they don’t perform as well as Adiseal. The performance of the product is more important than the brand name.

Details of benefits
Works in dry, wet & underwater
The very impressive Adiseal works in the dry, wet & even underwater. Imagine there is a leaking gutter and it’s raining outside. With Adiseal the leaking gutter can be sealed straight away even if it’s raining outside. As the rain is coming down, the location of the leak from the gutter can be seen & fixed immediately.
With other sealants, a dry day will be required first to apply the sealant & there is no way of checking immediately if the gutter has been sealed correctly or not. With Adiseal, the leak can be repaired & tested immediately. It will also provide good strong seal that will last a very long time. That’s just one of the reasons why Adiseal is the best gutter sealant.
Adiseal waterproof adhesive sealant seals & bonds underwater as well, meaning the water doesn’t need to be removed from the item being sealed or stuck to. This can save a lot of time and therefore money as well.
Adiseal is also the strongest waterproof adhesive available. It works great for many different applications where a waterproof adhesive is required providing a strong waterproof bond that will last a long time.
Tip – When using a waterproof adhesive where there is a chance of water running behind the item, it is best to apply the product in thin vertical strips. This allows any water to run down between the waterproof adhesive instead of building up on top of the waterproof adhesive.
Instant Power Grab
Adiseal is also a fast grab adhesive with very high initial power grab & grip, even on wet surfaces plus underwater as well. For even faster instant power grab, use the Adiseal Hi-Grab adhesive. It has phenomenal instant power grab & grip with an extremely strong bond. It is available as a white adhesive only.
For more information on the Adiseal Hi-Grab adhesive see the Hi-Grab page.
If there is no need for extra high initial grab or if temporary supports can be used then it is recommended to use the standard Adiseal adhesive & sealant. The reason for this is because the Adiseal Hi-Grab product is a very thick product therefore requires a lot of pressure to push the surfaces close together.
Please note the Adiseal colours have a stronger initial grab than the Adiseal Ultra Clear. It is recommended to use Adiseal Colours over Adiseal Ultra Clear when being used as an adhesive.
Gap Filling Adhesive
Adiseal has high gap filling properties and is ideal when trying to bond something where there is a gap between the surfaces of the materials being bonded. This is usually the case when the material is not smooth, for example natural stone that is roughly cut. The high gap filling properties of Adiseal allows a strong bond whether the surface is flat or not. Adiseal will also avoid slumping when used in overhead applications due to it’s high gap filling property.
In most cases other products like contact adhesives do not have high gap filling properties. This means even if the products is applied all over the surface area where the bond needs to take place between the 2 surfaces, if there is a high gap between the 2 surfaces, there still won’t be any product holding the 2 items together. This vastly reduces the strength of the overall bond.
Adiseal is available in the following colours: white, black, grey, brown & ultra clear. Adiseal can be manufactured in any RAL colour. It is also over paintable with most paints.
Tip – Own paint colour can be mixed into Adiseal Ultra Clear to make an adhesive & sealant match the exact colour required. Use a piping bag, tube or cartridge to apply the custom coloured Adiseal.
Adiseal is the proven strongest flexible adhesive available. A flexible adhesive allows a bond to be non brittle. Adiseal allows for movement due to temperature & moisture changes as well as soaking up vibration, creating the strongest flexible bond. The bond on a non flexible adhesive will eventually fail because it will become brittle over time. Using a flexible adhesive like Adiseal will create strong & longer lasting bond.
Adiseal does not contain solvents or isocyanate meaning it does not have that harsh solvent smell that comes from other products that do contain solvents. Other products containing solvents will require well ventilated area requirements for use. This is not a problem for Adiseal as it’s very safe & virtually odourless.
Solvents in an adhesive or sealant will attack any item it is applied to. Some items can be very sensitive to solvents like polystyrene which is a common insulation material in buildings & other items like bath panels. Polystyrene will melt when in contact with solvents. Adiseal does not contain any solvents making it non aggressive & the best polystyrene adhesive.
The backing on mirror’s are also very sensitive to damage from aggressive adhesives that contain solvents. Adiseal is the strongest mirror adhesive available on the market.
No Shrinkage or Cracking
Adiseal does not shrink or crack as it’s not filled with solvents unlike other products. Other products are filled with solvents to make them cheaper to manufacture but this results in there being less active product in the cartridge. This causes the product to shrink & crack as the solvents evaporate away. As Adiseal does not contain solvents, there is more active product in the adhesive sealant tube & therefore no shrinkage or cracking when it’s applied. Adiseal is also designed to stays permanently flexible and not become brittle.
Problem of using cheap products
One problem of using a cheap silicone sealant to seal a bath, shower, basin or any other item is that the sealant will start to peel away from the surface before it’s cured. This is because of the sealant shrinking due to the solvent escaping from the cheap silicone sealant. This is the same problem when using a cheap adhesive that contain solvents leaving a weaker bond than better products like Adiseal.
As Adiseal does not any contain solvents, it provides a much stronger bond & better seal that will last a lot longer than other products. Using cheaper products sometimes end up costing more as once they fail, it will have to be removed & replaced with new adhesive & sealant. This costs time & money, especially for tradespeople as they have to keep a reputation for quality work.
EC1 Plus certified
Adiseal is certified EC1 Plus meaning it has the lowest certified VOC for adhesives & sealants.
Adiseal is ISEGA certified meaning it is suitable for use in food preparation areas. Adiseal is the ideal kitchen sealant as it’s certified safe for use in food preparation areas.
Suitable for interior & exterior use
Adiseal is a high performance product that is waterproof. It performs equally well when used as an interior adhesive sealant as well as an exterior adhesive sealant.
Best construction adhesive & construction sealant for specific applications
Due to the high performance of Adiseal, it’s the best product to use for many different applications. It outperforms competitor products in many different applications including:
Adiseal is a multipurpose product but outperforms products that are made for specific uses. As well as it being used in DIY applications, it is also strong enough to perform on high end industrial needs.
Industrial adhesive sealant
Some of the high end industrial applications Adiseal has been successfully used is to:
- Bond industrial freezer panels where other products failed.
- Bond metal bearings to concrete bridges.
- Seal & bond a variety of applications on boats.
- Seal in warehouse used for a food manufacturing production line.
- Maintenance of University halls of residence.
For items that have a small surface area, the Adiglue glue product might be more suitable but will provide a more brittle bond than Adiseal adhesive & sealant.
The maximum strength of any adhesive or sealant will only be as strong as the weakest surface it is being applied to. If the products are being applied to a dusty surface then it will only be as strong as the dust that is stuck to that surface. To get the best results before applying any adhesive, sealant or paint is to make sure the surfaces the product being applied to are free from dust, oil, grease, paint, or any other dirt.
The Adisolve solvent cleaner product is the ideal product to prepare a surface. It is a very effective yet non aggressive adhesive remover, sealant remover & solvent cleaner in one product. Adisolve will also help remove oil, tar, grease, chewing gum, wax & many other stubborn deposits. Adisolve is available in a 500ml aerosol spray can.

Frequently asked questions (FAQ)
The best grab adhesive by far is Adiseal. It was the strongest adhesive in an independent adhesive strength test, way stronger than anything else that was test. Adiseal did not even break at over 3123 psi where as all the other products tested broke at 1115 psi or less, making Adiseal over 3 times stronger than the nearest competitor. Adiseal is also a waterproof adhesive sealant, seals instantly, flexible adhesive, gap filling adhesive sealant, UV resistant, solvent free & many other benefits.

In an independent test Adiseal was the strongest adhesive by far. It still did not break at over 3123 psi where as all other grab adhesives being tested broke at 1115 psi or less.
Grab adhesive is simply applied to the item being bonding, then just press down the item to the surface. Temporary supports may be required if the adhesive does not grip. To get the best results & strongest bond, it is required that the surfaces are clean from any dust, grease, oil, paint & any other dirt.
Adisolve is very effective at removing adhesives that are based on solvents. Simply spray Adisolve on the adhesive to soften it before using a sharp item to scrape off the old adhesive.
Adisolve is the best adhesive remover. It is non aggressive yet very effective at removing solvent based adhesives. Simply spray Adisolve on the adhesive to soften it before using a sharp item to scrape off the old adhesive.
Glue’s usually cure quicker than adhesives but tend to leave a non-flexible brittle bond. Adhesives have more initial grab & grip than glue. Adhesives also have a lot higher gap fill property than glue. Products like Adiseal are also flexible, unlike glue.
Adiseal Ultra Clear is the best clear sealant available. It is extremely clear once applied & stays clearer longer than other products even underwater.
A gap filling construction adhesive allows for a strong bond between 2 materials that are not completely smooth and have gaps between them in certain places, for example natural stone that has a rough cut. When a non gap filler adhesive is used between 2 surfaces with a high gap, the overall strength of the bond is a lot lower. This is because there will be no product between the 2 surfaces being bonded where there is a high gap.
To remove any excess uncured Adiseal, simply wipe it away with a thick cloth. The Adisolve product will also help remove any uncured Adiseal.

Although some grab adhesives have a higher initial grab than others, grab adhesive & construction adhesives are the same type of product.
Adiseal construction sealant & construction adhesive will outperform other products. It’s proven to be the strongest construction adhesive in an independent adhesive strength test. Adiseal is also a great construction sealant. It’s a waterproof adhesive sealant, seals instantly, stays permanently flexible & does not shrink or crack.
Yes Adiseal is a waterproof adhesive as well as a waterproof sealant. Adiseal can be used in places where non waterproof adhesives will not work.
The advantage of using flexible adhesive is it will allow for movement and not become brittle. Movement occurs due to items expanding & contracting because of temperature & moisture changes. The bond on a non flexible adhesive will be brittle therefore it will become weak very quickly. A bond on a flexible adhesive will last a lot longer than non flexible bonds, especially where there is movement is involved.
The final bond strength of both Adiseal & Adiseal Hi-Grab are similar. The only difference is the initial grab. If there is no need for extra high initial grab or if temporary supports can be used while the adhesive dries then it is recommended to use the Adiseal adhesive & sealant. The reason for this is because Adiseal Hi-Grab is a very thick product therefore requiring a lot higher pressure to push the 2 surfaces together. Having the 2 surfaces are close together will result in a much stronger bond.
When Adiseal is used as an adhesive only, it is recommended to use Adiseal colours over Adiseal Ultra Clear. Adiseal colours have higher initial grab & final bond strength.
