There are different techniques to apply the glue on the latex, none of them is right or wrong. That what matters is what works best for you. So see this as suggestions!

To apply the rubber cement

Remember to apply glue on both seams you would like to glue together and to have a equal thin layer of glue!

1. Paint brush
I prefer small, flat soft brushes. It makes it easy and fast to apply the glue on the latex sheeting and gives you a good control over that what you are doing. Remember to clean your brush properly after you finished your project.

2. Cotton buds
They are cheap, you have them always in the house and they give you as well a good control. Just throw them out after they a unusable anymore. Usually you will need a couple to finish one project. I also use them from time to time.

3. Old Credit cards etc.
I have also seen people using those to apply glue on the latex and had to try it myself. What to say, not the right method for me! Not handy at all, especially if it comes to curves, less control and it makes in my eyes a too big mess on the workspace.

To apply the white latex milk

First of all you have to apply this glue fast, equal and in a thin layer! Dont wipe to much around with your brush on the latex or it will cause little dried glue “left overs”.
You have to wait until the latex milk dryed on the latex. When the white latex milk turns transparent after you applied it, you know that its ready to be glued together. Just give it a few minutes.

1. Paint brush
You can of course also use a brush for this glue. It should be soft and clean. It might take 2-3 strokes over the to be glued seam to get a nice layer of glue on the latex sheeting. Dont put much glue on your brush or it might make a mess on your workspace

2. Sealing tape
This is like using a small piece of a sponge. You will need a long flexible piece of plastic, metal or wood etc. to place a piece of the sealing tape on.
Then you will “dip” it slightly in the glue (Not to much, a drop of glue on the sealing tape is totally fine! You can always add more!).
Then apply the glue on your seam. But be fast, otherwise your sealing tape starts to stick to the latex sheeting and it leaves little traces which you might see later after you are done gluing. You would be surprised how fast that can go!
