Do you guys use 3M 77 for anything other than fixing patterns to wood? I’ve been using 3M 77 for a few things around the shop lately and was curious what you think.

One thing that I did last week was that I needed to face join two pieces of MDF for a jig. I new that I was going to reinforce it with screws but I wanted to glue it too. Using yellow glue can be pain, as you know, because putting a clamp on it is like walking on ice.

Tonight I made the drawer for my new DP table. It’s a small drawer, about 8×10 x 4 and it’s installed w/out slides. I wanted a way of stopping the drawer so that I don’t pull it out and dump everything on the floor. So I 3M 77’d a short piece of hardboard to bottom of the drawer frame. Thinking that if I couldn’t tip the drawer enough to get it over the cleat, it would be a lot easier to remove. It was quick and easy.

Anyone else using 3M 77, or something similar, around the shop?

It works well for lining boxes and drawers for jewelry boxes. I don’t use it for anything that requires structural strength though.

I use 3M77 to attach wet/dry paper to glass plates for sharpening. When worn, the paper can be removed with a putty knife and mineral spirits. I understand that the 3M90 adhesive is much more permanent.

I haven’t used it for several years. Thanks for the reminder about how handy it it :-))

If that is the spray stuff, I use it sometimes to adhere flocking inside boxes.

I have a can on the shelf. As mentioned, it is great for box interiors and adhering sandpaper to something…or other similar uses. I even used it to adhere cardstock paper to some melamine to make a temporary sign. Best part is that while the bond is strong and will hold whatever you are gluing without the edges peeling, it is not permanent. So, you can replace the sandpaper pretty easily and not ruin the substrate. I pulled the cardstock off the melamine, in one piece, and now have good-as-new melamine.

I agree with sawdust that I would not use it for anything requiring structural strength…its not THAT strong.

A can on the shelf is a must in my shop…I mean garage! :)

Theresa,
Do you use it instead of the colored lacquer? Does it work well? Coverage OK?
Thanks,

Another tip:

If possible spray 3M77 outside, or have a lot of back-up paper. The overspray can create a “tacky” mess that is hard to clean up.

8iowa is exactly right…and make sure your car is not down wind from you when you spray it in the driveway! :)

Hey Gene, What I do is use a layer of PVA glue watered down a bit to get an even coat, then put in the flocking. this is because I am really lazy- when it’s all dry I then use a spray of adhesive to do another layer of flocking. It can be a bit fiddly on some of the smaller boxes (if you dont want to get glue everywhere I sometimes make a template so I don’t spray the unwanted areas) but works well on large pieces. And the flocking is thicker too.

Now here is a prime example of what this site should be about without the malarky.
Someone asked a simple question, got simple informative answers and we all learned something.
Thanks TJ and all the rest with suggestions. :-)

I use it in place of double sided tape for aligning drawer fronts to drawers.

Gregn: Great idea.

Something other than sticking paper.
