I will show how to apply acrylic type edge coat among the two types mentioned above.

The photo shows the watch strap.

You first need to clean the cross section before applying the edge coat.

Since edge coat is well applied if there is no section difference, you’d better to clean the cross section with thick sandpaper right after bonding.

The small block at the bottom of the photo is block sandpaper made easy to use by covering sandpaper.

Remove as much section difference as possible by pushing the block sandpaper a little stronger.

Then, you can clean the cross section by using sandpaper in various steps as shown in the photo according to the purpose.

From the left, there are a little thick sandpaper and thin one.

Thick sandpaper is often used in the early work since it sands the leather a lot. And the thinner sandpaper is used to clean the applied edge coat rather than the leather.

One tip here is that if you use thick sandpaper, you can use all the sandpaper at a lower step to clean the surface more neatly.

If I number from 1 to 4 from the left, you can use 1, 2, 3 and 3 for first grinding, 2, 3 and 4 for next, 3 and 4 for the next and 4 for the last. But this is a tough work.

If you sand too strong, fluff on the cross section of the leather can be made. So just sand the leather as if you hit them by speeding up. And it’s better to clean the fluffed cross section of the leather

This time, we will apply brown edge coat made by Japanese IRS. For reference, you’d better to shake this edge coat up and down before use so that the ingredients are evenly mixed. Since it is made up of various ingredients, there is something deposited depending on the specific gravity.

I use magic form as a tool to apply acrylic type.

This magic form is the cleaning item as you think.

It can be cleaned without detergent, but it is very useful when you apply slightly watery acrylic type.

If you apply edge coat on the magic form, it can moderately permeate on the magic form. Then, edge coat will come out when you apply it by adjusting strength.

For reference, it is good to use edge stick for the thick one like urethane type.

Then, I will arrange from №1 with sandpaper.

Put a little edge coat on the end of the magic form. And wait for 3 to 4 seconds to penetrate into magic form.

I will apply it for the first.

The surface is very rough when first applied.

For the surface that is not smooth

I will use №2 sandpaper.

If I apply it again, you can see that it is a little clearer than the first.

You need to repeat this process until the surface is smooth. And if the edge coat is spread aside, you should clean it immediately. If they are dried, it can be hard to erase.

Dry the surface applied by edge coat enough.

I usually repeat the above process at least 3 more times.

I think it is well applied.

To apply the edge coat well

1. The leather cutting should be done well.

2. There should be no section difference between the two leathers

3. It is cleaned with sandpaper

4. Apply edge coat so that the grain is not made.

Above all, patient about the series of works of applying, drying and grinding is necessary.

It is quite tedious works than we thought.
