Loctite Sumo Glue Instructions
Selected instructions from archived web site for Loctite Sumo Glue:
How should I apply Sumo Glue?
Apply Sumo Glue with a pure mind and heart. This is the essence of the Sumo Master.
First, make gluing surfaces clean, and be sure fit closely together, like two sumo warriors in mid-struggle. Lightly sand very smooth surfaces before gluing to get better stick.
When bonding porous surfaces like wood, concrete and stone, apply Sumo Glue evenly to one surface and clamp for at least 30 minutes.*
When bonding non-porous surfaces, such as metal, plastic, glass, dampen surfaces to be bonded, apply Sumo Glue evenly to one surface, and clamp for at least 90 minutes.*
*Clamp time depends upon humidity. Low humidity may extend clamp time.
Why do I need to add moisture prior to gluing?
Sumo Glue needs moisture to cure. The less moisture that is present, the slower it will cure. Porous surfaces often have more moisture. Non-porous have less so you may add moisture to accelerate the curing process.
Moisture is a small price to pay for the awesome power of Sumo!
How much glue should I apply?
Enough. A Sumo Master would not need more guidance. But you are still learning so I will interpret.
Apply a few drops so that you can evenly and uniformly coat both of the materials you will bond. Too much and it will make a mess. Too little and it may not stick.
Why do I need clamps to repair things with this glue?
Polyurethane adhesives foam during the curing process. This is inherent in the technology and although Sumo foams less than other polyurethane glues, this foaming can still push unclamped parts apart from each other as the product cures. Clamping is required to maintain positioning until the glue is set.
I clamped my repair and some glue came out of the sides, what do I do?
Always keep your composure. Wipe any excess glue and foam from the parts before it cures. If you are reading this too late, dried glue can either be cut away with a sharp tool, or sanded away after cure.
How do I store Sumo Glue once it is opened?
With great reverence. After using Sumo Glue, squeeze out the remaining air prior to closing the bottle, and secure the cap tightly. Store in a cool, dry place, and not in direct sunlight. If air remains in the bottle during storage, the glue may skin over in the bottle. However, if the skin is removed, any liquid portion of the glue can still be used.
When should I Sumo it?
When your project or repair requires a high strength and/or a waterproof bond, use Sumo Glue!
