Creating a faux lime stone wall treatment
In the design of the Moroccan bedroom, I created a faux lime stone on the upper walls. If you don’t mind getting a little messy, with a little patience this can be a fun project and it’s also very easy to do!
Five gallons of all purpose joint compound
1 cup water
1 tube caulk (do not use the silicone caulk)
Terry cloth towels
Paint roller with a 1” to 1 ½” nap
Start by mixing the joint compound, water and the caulking. I use a metal paint stirrer and attach it to my drill so it’s easier to mix. I’ve been known to divide it in smaller buckets using my hands to mix it but I will warn you this can be messy! It provides a nice arm workout though.
Next you apply a generous amount of joint compound to a clean wall. You don’t need to prime the wall unless it is painted with a high gloss finish, otherwise you’re good to go. I like to apply a rather thick coat of the compound mixture, about a quarter inch or so using my trowel. (Don’t worry about keeping it the same height or how smooth it is, you don’t want it to be perfectly level as limestone is not perfectly level. Trowel on the plaster in sections of 4’x4’ and let it set for fifteen minutes. This is where it gets fun…
Decide how large you want your blocks to be and using a yardstick, gently press the thin edge of the yardstick across the plaster to form a line. Continue to do this in the entire section, creating rectangles. Now, use your finger and follow this line, scooping off the joint compound so it now becomes dimensional and the blocks begin to take form. Have your Terry cloth or rag nearby because it can get messy. Don’t worry about if the lines are perfect, old world limestone doesn’t have a perfect look to it.
Next you will use the paint roller. Wet the nap with water and ring it out so it’s not too wet. Gently roll over the plaster but don’t press too hard, you don’t want to flatten the plaster. What you are doing now is creating a stone like texture and the nap of the roller provides this textured look.
As the plaster dries, it will slightly crack in a few places but again this adds to the old world look. Wait at least 48 hours before you paint the wall so the plaster has time to cure. Have fun with this project and I promise people will be amazed at what you just created with a little bit of plaster and your finger!
Because as we say, design matters!
