The Redstone Paste Mod adds the ability to turn redstone dust into a paste that allows you to place it on walls and ceilings.

The Redstone Paste can be placed in a variety of directions that will allow you create a more compact redstone path. It breaks up the blocks into four sections. Each section can be removed after placed or you can click the center of the block to remove the paste from the whole block.

The Paste is easily created by combining traditional redstone with slime balls. You can also create sticky repeaters and sticky comparators to help maintain your redstone paths to your desired length.

Probably the best feature of this mod is the ability to place the paste underneath slabs. This allows you to create a much more compact system. You can even place a slab over the path on a wall.

You can also use the paste in conjunction with regular redstone if you directly connect the lines. However, you can use it independently running next to redstone and still maintain both connections without any issue.
