Stunning 3D Stencils Are fun, Beautiful & Super Easy
If you can smear frosting on the top of a cake, you can do it!
Though nearly all stencils can be used with plasters, most won’t hold up to plaster use. We use only 14 mil, super heavy duty mylar for our Raised Plaster Stencils because it holds up so well to repeated use.
Mediums to use
3D Stencil Paste (sold in our store)
Pre-mixed joint compound (found in any Walmart or Home Depot)
You can also use paint (roller or brush) - but of course the design will not be raised.
Joint compound dries pure white, but you can pre-color it with any water based paint such as craft, wall paint, and water based tints.
Begin by choosing where you plan to plaster your design. Plaster stenciling can be done over any wall paint (including high gloss), wood, furniture, cabinetry and craft items. It doesn’t do well on glass, mirror or metal. They’re too slick and non-porous.
What you will need:
Masking or painters tape
Plastic scraper or small plaster trowel (we sell scrapers in our store)
To begin, tape the stencil in place to the intended area.
If you are pre-tinting the joint compound, put some in a separate container before tinting. If you choose not to tint it, but to paint it later, simply use it right out of the bucket.
Scoop a small amount of joint compound on to your scraper or trowel. Tilt it to about 45 degrees and then lay the edge of the scraper on the stencil and drag the compound over the stencil openings using a medium amount of pressure. Try to work in the direction of the design wherever possible. On this medallion, I’m working from the outer edge toward the center.
Scrape the compound even with the stencil. This forces the compound down in to all the tiny openings to give you a clear, crisp image. With large openings, use your fingers to hold the opening down as you plaster to prevent it from raising up.
Now, if you want your design thicker (with a higher profile), without removing the stencil, pile on more compound. I get mine up to 1/2″ thick on larger designs and over 1/4″ on designs with smaller openings.
Untape the stencil and while holding down one edge, peel the stencil back gently (do not just lift it off the wall).
Tah Dah! There’s the raised design in all it’s glory!
If you wind up with peaks or ridges that you don’t like, or if you pressed a little too hard and it bled up under the stencil openings, simply wipe it away with a Q-tip. Ridges and peaks can simply be wiped with a damp sponge after it has completely dried.
Now, let it dry completely. This usually takes about 45 minutes to an hour before doing a repeat right next to it. (As in the case of a repeated border or wallpaper stencil design).
To finish - here are some options:
o Keep it as is
o Gently sand if you want to remove sharp edges
o Paint - I like to paint it the same color as the surface and highlight the design with some gilding wax
o Dry brush - paint using a dry brush so some of the white shows through
o Seal - with your favorite sealer
Plaster stenciling can be done outdoors! The exterior surfaces of your home, planter boxes, deck rails and even stair risers can be decorated with raised plaster stenciling. Simply seal the plaster with exterior paint to protect against the elements.
