Walls and Ceilings - Need a wall texturing solution

I have a bad tape/mud job -- mine -- that needs to be covered with some kind of very heavy texture.

Can I mix mud and paint to do the job in one textured coat? What solutions do others who are bad at taping use?

This is an easy and cheap way to texture.

I'm not sure what they are called, but at your drywall store where you purchased your tools there are probably some metal squares with handles in the middle. Buy 2 of those and a bucket of joint compound.

Water the compound down just a little, you want it kinda thick for texturing..

Put a thin coat of mud on both squares and then slop 3-4 random blobs of it on 1 square. Holding both squares, press them together and pull them apart repeatedly to evenly distribute the mud, rotating 1/8 a turn each time you press and pull. You'll end up with pointy mud on both squares. Press the squares against the wall, rotating it for each section. Only do about 3-4 blocks at once for each square and then add more mud. It goes a lot quicker if you have someone to fling the mud on your square while you are holding them so you don't have to keep putting one down.

After that take the widest taping knife you have and run across the mud pressing it flat (not completely flat of course).

Unless you're really good at it, you'll probably want to sand down any ridges and lines the day after.
