View Full Version : Sanding instead of sealing?

After gluing and removing rubbers from a Yinhe Earth 3, which has a really smooth finish on the blade face, and a Korbel, which has a less smooth surface than Yinhe (for my surprise), I noticed something obvious. It is much easier to apply glue and remove rubbers from a smoother surface.
Based on this, since we seal the blades basically to prevent it from splintering when removing the rubbers, what about sanding the surface to get a really smooth surface instead of sealing it?

Off course I’m talking about the finest grit sandpapers to only work on the smoothness, and not to remove thickness. Also, using a straight block and all proper care.

My only concern is if the water on the water based glue could do actual damage to the blade over time.

If you don't seal the blade may be you'll regret.

Yes, seal AND sand. In my (not unlimited) experience the sealing process roughens up the surface a bit, so I usually apply a very thin layer of sealant, let it dry a day or so and then very gently polish it up with a (very) finegrained sandpaper.

Sanding defeats the purpose of sealing, if the sanding exposes the blade at all to the elements.

You want the surface just slightly rough for adhesive purposes. I'd be careful with sanding unnecessarily, easy to get wrong if you aren't experienced.

Did anyone experienced any actual damage to the blade due to the water on the glue?

No. Which is confusing.
