What Is Construction Adhesive?
Construction adhesive is a high-strength bonding product designed to attach building materials together. It is commonly used in construction, renovation, installation and repair work where a strong, durable bond is required.
Unlike conventional household glue, construction adhesives are formulated to bond larger surfaces and different building materials, including wood, concrete, brick, metal, stone and certain plastics.
Construction adhesive is available in different formulations, each offering different properties depending on the application.
Different Types of Construction Adhesive
Understanding the different types of construction adhesive helps you choose the right product for your project.
| Adhesive type | Typical characteristics | Common applications |
|---|---|---|
| MS Polymer | Flexible, moisture-curing and versatile | General construction bonding and sealing |
| Polyurethane (PU) | Often provides strong, durable bonds; flexibility, moisture resistance and curing characteristics vary by formulation. | Wood, masonry and building applications |
| Solvent-based | Often provides strong initial grab | Installation and general construction |
| Acrylic | Often water-based and easier to clean before curing | Interior trim and lighter applications |
| Epoxy | Typically high strength and rigid after curing | Specialist bonding, repairs and structural applications |
The best construction adhesive depends on the materials being bonded, the environment, the required flexibility and the loads involved.
MS Polymer construction adhesives are particularly useful where a combination of strong bonding, flexibility and resistance to moisture is required. Unlike many rigid adhesives, they can accommodate movement between bonded materials after curing.
What Is the Strongest Construction Adhesive?
Adiseal demonstrated exceptional bond strength in an independent construction adhesive test conducted by Ultimate Handyman.
During the test, several construction adhesives were subjected to increasing pressure to determine how much force their bonds could withstand before failure. A hydraulic ram was used to try to break the adhesive bond between wood and metal.
Adiseal exceeded 3,123 PSI without the bond breaking. The test was abandoned because the testing equipment approached its limits.
This means 3,123 PSI represents the minimum demonstrated strength in this test, rather than the actual maximum strength of the Adiseal bond.
Independent Construction Adhesive Strength Test Results
The table below shows the maximum pressure recorded for each adhesive during the independent test.
| Product Name | Max Pressure Recorded (PSI) | Test Outcome |

2. Permanent Flexibility
When two building materials expand or contract at different rates, a rigid adhesive may experience stress at the bond line. A flexible MS Polymer adhesive can accommodate some of this movement, helping maintain the bond.
Adiseal remains flexible after curing, helping accommodate thermal expansion, contraction and mechanical vibration.
3. Excellent Gap Filling
Construction surfaces are not always perfectly flat or even.
Adiseal’s gap-filling properties help bond irregular surfaces where small gaps exist between materials.
This makes it useful for construction applications involving masonry, timber, metal and other building materials.
4. Waterproof Bonding
Adiseal is formulated to provide waterproof bonding and sealing.
It can be applied in dry and wet conditions, including underwater applications, making it suitable for certain repairs and installations where moisture is present.
For the best results, always follow the product’s application guidance and allow sufficient curing time.
