Glazed Metallic Plaster Technique

Here’s a very cool and dramatic looking faux finish I think you’ll like. It works great as an accent wall or in, dare I say it, powder rooms. The images attached to this post shows the finish with a harlequin design and upholstery tacks to embellish the finish but this decorative faux finish could stand all on it’s own.

The process to create this decorative finish is rather simple but the finish does use some specialized materials. The materials needed are Palette Deco, a metallic plaster and Stain and Seal. Both of these products are from Faux Effects International. Faux Effects manufactures a wide array of decorative and faux finish products including venetian plasters, metallic plasters and glazes and all kinds of media to create distinctive decorative and faux finish techniques.

This technique begins with a base coat of black satin paint. Once this black base coat dries fully you will roll on a thinned coat of the metallic plaster. The metallic plaster I choose for this first scratch coat was copper and I thinned it with a mixture of 1 part water and 1 part glaze. A 100 % coverage is needed but allow some of the black base coat to peak through. The first coat of rolled plaster serves a scratch coat for the subsequent coat of plaster that will be troweled on.

Once this first coat of plaster is dry, you will trowel on two colors of metallic plaster at the same time. I selected copper and red but the colors of this decorative finish can be changed to suit your needs. Trowel on the red and copper plasters together blending them as you go but making sure to leave areas where both colors are distinct. In other words, don’t over blend the two metallic plasters until you they become one color. This layer should be pretty much a tight smooth coat. Allow to dry fully.

This next step is where the texture of the finish is created. You want a certain amount of depth and texture because the nooks and crannies is where the stain will accumulate and give the finish real depth. I created this texture by using a plastic grocery bag. I take the bag, bunch it up and dip it into both metallic plasters. I then pounce the bag lightly over the surface just enough to deposit irregular bits of the plaster through out the surface. I allow this plaster to set up a little bit then lightly knock it back down with a plastic trowel or bondo knife.

The final step in this faux finish is to give the entire surface a unifying and toning glaze. I used Stain and Seal in the color Rich Brown. The stain is thinned down with about 20 % water and applied with a 4 inch chip brush. I then smooth and feather out the stain with a cloth rag. In some areas I may go a little heavier with the stain in order to add further depth to the finish.

Once this stain coat is dry, I can then add the diamond pattern. My trick was to use a Sharpie to create the diamonds. Finally, to further embellish this decorative finish, I used upholstery tacks and placed them at the intersecting lines of the diamonds. This decorative finish doesn’t need to be top coated as the stain does that for you.

Try this technique using any combination of metallic plaster and different stain colors to create a variety of very distinctive looks.
