Create Faux Stone for Collages

How to Use Drywall Compound in Multi-Media Collage

Drywall compound is an excellent medium to use when you want to add depth, dimension, and weight to a collage or multi-media piece. It is also very easy and fun to use.

Supplies

• canvas
• collage components
• adhesive (decoupage medium is a good choice for the paper elements and a sturdier adhesive is desirable for the heavier elements)
• drywall compound
• putty knife
• crayons
• blow dryer
• beeswax
• slow cooker or electric skillet
• brush

Technique

1. Design your collage layout. Remember to leave space for drywall compound wherever you want to have the faux stone look.
2. Fix all design elements in place using adhesive of choice (Figure 3).
3. If you are using paper elements and don't wish your crayon to color or soak into them, brush a coat of decoupage medium over the element. The medium will create a resist that won’t allow the crayon to soak into it.
4. Use a putty knife to smooth drywall compound wherever you want on your collage (Figure 4).
5. Allow the drywall compound to thoroughly dry (if you do not allow it to dry completely, you risk cracking it in the next step).

If you like the white plaster look of plain compound, you are finished. However, if you want to add color for a faux stone look or the look of painted plaster, continue.

1. Select several different colors to use on the drywall. Color the drywall while at the same time blow-drying the area you are coloring (Warning: Be careful. Avoid burning yourself).
2. The crayon will melt and absorb into the drywall compound, incorporating the color into the "stone" for an aged look. Switch crayons regularly for a blended effect. (If you have more crayon wax than you want, it can be absorbed with a paper towel).
3. Place beeswax in the skillet to melt.
4. When you are satisfied with the coloring results, seal it with a coat of beeswax. Paint the wax on with a brush and then use the blow dryer to smooth the finish and blow off excess wax.

Suggestions and Ideas

• It is a good idea to buy color changing drywall compound so that you are certain that the compound is dry. Many compounds will go on pink and turn white as they dry, making it foolproof.
• Drywall compound is brittle so avoid leaving sharp peaks or they will break off later.
• Try smearing a little compound over three-dimensional pieces to make them look buried.
• For a decorative hanger, drill holes through the collage, string a piece of hemp through the holes and use beads to anchor it (Figure 1).
• Instead of using canvas for the foundation of your collage, try recycling an old clipboard for a fun self-hanging collage (Figure 2).
