Unibond 800 FAQ
Q: What is the coverage per gallon?
A: Between 200 and 250 square feet depening on the porosity of the material being glued.
Q: Which is the Glue and which is the catalyst?
A: The liquid resin is the glue and the powdered hardener is the catalyst.
Q: How water resistant is Unibond 800?
A: The glue can be used in high moisture conditions as well as exterior exposure but not where it will be sitting in water continually, like the hull of a boat.
Q: How do I determine if my glue is still good?
A: The simplest way is to examine the viscosity of the liquid resin. Unibond 800 will thicken on itself when the shelf life is up. When usable it is roughly the consistency of maple syrup. When the shelf life is up it thickens to the consistence of a cold honey.
Q: Will Unibond 800 Work on oily woods?
A: Yes, it works very well on oily woods.
Q: How do I apply Unibond 800?
A: A foam roller and paint pan applies a thin uniform glue line quickly and efficiently.
Q: What is the average shelf life of Unibond 800?
A: Shelf life depends on the temperature the glue is stored at. The colder the storage temperature, the longer the shelf life. Glue kept in the fridge will last well over a year. The powdered hardener has no shelf life.
Q: What is the working time of Unibond 800 once it is mixed?
A: Once the hardener is mixed with the liquid resin the work time of the glue depends on two factors, the amount of hardener added and the room temperature. Low room temperature and a “slow mix” allows for up to 45 minutes, high temperatures in the 90’s and a “fast mix” could start to set in as little as 15 minutes.
Q: How do I choose which hardener I should get?
A: Unibond 800 comes in two hardener colors, medium brown and dark brown. The medium brown hardener is a good match for woods in the tonal range of cherry and oak. The dark brown hardener is ideal for woods like mahogany and walnut. For very blonde woods Unibond 800 white tint can be added to the glue.
Q: Do I need to apply glue to both sides of my work with Unibond 800?
A: Except for commercially sliced “raw” veneer (which you never apply glue to the veneer). Both sides or just the substrate is fine. Obviously you guarantee good glue transfer if you apply lightly to both surfaces.
