« Part 5: Time to Zig Part 6 of Router Table Extension Wing series no next part

This weekend I decided to work on my workbench a bit so I put this project to the side for a while. While I was out working I took a really close look at the laminate and noticed that it is starting to debond at the edges! I have no idea why this is happening or if it will stop. I put the top on a flat surface and piled up as much weight as I coudl find on top to try to press the laminate down. The final cure time on the contact cement is supposed to be 7 days and I made the top 7 days ago so it is probably too late. The top came out really nice so I hope that this is just limited to the edges maybe and doesn’t cause any kind of waviness on the top.

If anyone has any ideas why the contact cement didn’t stick properly let me know. As I wrote in the entry where I put the top on I noticed that the wood kept sucking up the cement and I had to really apply a lot in order for the surface to be “glossy” the way the instructions said it should look. So far my guess is that I didnt put enough cement down along the edges.

Termite you don’t say how many coats of contact cement you put on before putting the laminate together. I have had great luck with 2 coats on both surfaces that will be put together. Let each coat dry to the touch before putting on the next and then let the final coat dry.

Once it is dry to the touch the final time put your separator sticks on and then the laminate. Start to remove the sticks from the center out. Use a hard rubber roller to remove the air bubbles when you have them all out, and then put on the clamping culls! Leave the culls on for 48 hours! and let dry for another 48. After that you can trim edges and do what ever you need to finish up.

I know it isn’t following the directions but sometimes you have to go with the old timers. A fantastically smart man told this to me a loongg time ago!

I used two coats on both pieces and then added some touch ups after that to areas that were not glossy. I also didn’t have a roller so I tried something different and now that I think about it I realize you really need a roller. I am also not too sure how well I applied pressure to the edges and I didn’t use any clamps or weights while the glue was drying. :(

I found some information online about repairing laminate countertops. Apparently you can reactivate the contact cement with a clothing iron. I am going to see if I can heat the surface enough to reactivate the cement and then roll it out (with the roller that I now own) and then leave some weight on the top.

Hopefully that fixes it.

I had the same experience and fixed it.The iron didnt work for me but my heat gun did.Getting it too hot concerned me but didnt seem to be a problem.I used clamps and cauls as you really cant stack enough weight on to equal the clamp pressure.I left the clamps on for 24 hours and it has stayed stuck for over 6 months so far.I didnt have a roller and was too cheap to buy one.
