Start taping. I wanted to have more of a stone look than a brick. With a brick pattern you may have to use a ruler or level. You can see the fireplace is just wood. Almost like the back side of paneling
Fireplace Faux Stone
Took my plain paneled fireplace and made it look like stone. Less than 4 hours and less than $10
I tried to only have the top center have somewhat of a pattern
Mud all over the tape as well
Carefully while the mud is somewhat wet, pull the tape off. If you wait too long the mud will dry and you'll have trouble. After the tape is all off I used a fan to speed up the drywall drying process.
Now just start painting over the mud. I used all leftover paints I had. Used an aluminum foil plate to mix some colors together. I even used a bronze and a black spray paint I had.
Keep painting until you like what you see I guess.
Finished and enjoyed a fire by the end of the night. Less than 4 hours!!!!
