DESCRIPTION
Weldwood Instant Adhesive creates a professional-strength bond that works on all wood types. Weldwood sets in 30 seconds and is ready to plane, sand, or stain in just 30 minutes, minimizing clamping time and getting you back to work faster. Weldwood Instant Adhesive is even repositionable for up to three minutes, giving you time to ensure PERFECT alignment. The clear water-resistant formula is good for indoor and outdoor use.
Don't Use Too Much
Don't use too much - only a small amount of Weldwood is needed.
Joints Fit Tightly Together
Make sure the joints fit tightly together. If you can't make the surfaces touch by clamping, you won't be able to get a great bond.
Cures in 30 Minutes
After 30 minutes of cure time, you can plane it, sand it or stain it. Go ahead. Really. Don’t wait overnight. After 30 minutes it's ready.
Clean, Dry Wood Surface
Start with clean, dry wood surfaces.
If it is Shiny, it is Still Wet
A good rule of thumb to follow when working with Weldwood is if it's shiny, then it's still wet. If Weldwood doesn't cure in 30 minutes then it's likely you over-applied. Simply use a dry paper towel to remove the excess and it will cure properly.
One Surface Only
Apply Weldwood Instant Adhesive to one surface only – not both sides.
After pressure is applied for 30 seconds the initial bond is formed. The bonded repair will cure in 30 minutes. If by chance you didn’t get the initial positioning correct, you can still pull the assembly apart and reposition it within 3 minutes and apply more pressure for 30 seconds.
Weldwood has an open time of 40 minutes – when it is applied in a bead and not spread or touched by both substrates. When you have a big project to complete where 3 minutes of reposition time is not long enough, apply adhesive to one side without spreading to give yourself more time to work. As soon as you use anything to spread the glue or touch both materials together to begin the squeeze out process you will only have 3 minutes of reposition time left to work.
Use Acetone to get cured Weldwood off your skin. Make sure it is Acetone nail polish remover. The non-acetone stuff won’t work. Wash your hands first to remove any un-cured adhesive with soap and water. Then wipe with an acetone soaked cotton pad. Do not try to pull or peel Weldwood off.
You can clamp most projects for just 5 minutes. For the maximum strength bond achievable, clamp for the full 30 minutes.
Just enough to cover the area you intend to bond with a thin coat of adhesive. If it is a wide area you will be bonding, apply the glue in an “S” pattern to apply enough glue to cover the bonding area when squeezed together. When you clamp the pieces together, you will need to wipe away any excess that squeezes out with a paper towel.
Cured adhesive may be cut away with caution using a sharp blade or removed with acetone (if appropriate/compatible with your application surfaces).
Yes. Weldwood is sandable, stainable and paintable. If you have excess cured adhesive on your project, you can scrape or sand it away. And you can stain or paint the cured adhesive that remains.
Weldwood is repositionable for up to 3 minutes. You can pull your pieces apart and realign them for a perfect fit for up to 3 minutes and still get a full strength cured bond. When bonding other materials to wood, like metal, plastic or glass, your reposition time will be less and can range depending on how much adhesive you apply. Don’t apply pressure until you have your pieces lined up perfectly.
