Get some cheap wood glue. Any brand at all, I use some I got in a 99p store.
Start the turntable, pour the glue on the record slowly moving from inside to outside.
Ensure the glue is even distributed over the entire surface of the disc. Any large gaps here will cause problems when spreading the glue in the next stage.
As the disc is rotating on the platter, use an old credit card to spread the glue evenly all over the record. Ensure there are no gaps anywhere and try to form a uniform thickness.
Once spread, leave the glue to dry for an hour or two depending on how thickly its spread. Keeping the turntable on increases they drying speed of the glue.
When the glue has dried, it will become translucent and dry to the touch. Keep your eyes out for wet spots or patches of thicker glue. It is not possible to remove the glue until it is 100% dry. If in doubt, leave it another hour.
One you’re sure it’s dry, pick away a small part off the run in grooves. It should come easily enough.
Slowly and steadily pull the glue off. Try to keep it at 90 degrees, this will decrease the risk of the sheet of glue breaking.
After removing the glue, your record is now good to play. I recommend taking it off the platter to dissipate the static. Before playing, make doubly sure there are no spots of glue left on the record. If there are, you’ll need to start the process again.
And that’s that.
