Give pretty much any object, metal or not, the expression of pewter by layering and texturing glaze over a gray or silvery base coat. The secret to a successful artificial pewter impact is to utilize matte or non-shiny paints, otherwise the artificial finish may appear more like aged steel or silver.
Cover the work surface with paper, and then set the job piece in addition to it. If you are making the end on a wall or other immobile surface, cover the ground at the surrounding area with paper.
Scuff up the job area with fine-grit sandpaper, sanding only sufficient to make the area more receptive to primer and paint. Wipe the dust away with a clean rag.
Cover places that you don’t wish to paint with painter’s tape, then smoothing the tape borders along the project surface.
Open and stir the primer, pouring some of it into a paint tray. Brush a coat of primer over the entire project area, and allow it to dry fully.
Open and stir the gray or silver latex paint, and pour some of it into a paint tray. Coat the entire project area with a layer of the paint, allowing it to dry fully. If the primer is still visible in some places, apply a second coat of paint, and then allow it to dry as well.
Pour a tiny clear latex glaze to your container, and include approximately two times as much silver paint. Mix both together with a paint stirrer. Examine the shade by brushing a small onto a scrap of paper or cardboard painted the dark gray shade; mixture in a drop or two of black paint, if needed, to tone and darken down the silver.
Ball up a paper bag and then dip one side into the glaze mixture to get a small amount of glaze. Pounce the bag all around the project, reloading it with the glaze blend as needed.
Soften the appearance by gently wisking a feathering brush or soft makeup brush during the wet glaze; that blends the end and makes it appear more realistic. Allow the glaze to dry fully.
