Most paints are formulated with chemicals that provide them with varying levels of sheen. While enamel, gloss and semi-gloss paints have high sheens, flat, satin and eggshell paints have little to no sheen. If you are unsatisfied with the amount of sheen on a painted surface, you can make it look duller by utilizing friction-based abrasion methods; however, if the surface is very large, this technique could prove tedious. In this case, your best bet is to repaint the surface with low-sheen paint. Learn the proper way to condition the existing glossy finish for adequate adhesion, or the new paint will flake.
Things You'll Need
- 500-grit sandpaper
- 100-grit sandpaper
- Canvas drop cloths
- Painter's masking tape
- Flat, eggshell or satin paint
- Roller frame
- Polyester paintbrush
Dull Existing Paint
Sand the glossy painted finish lightly with very fine, 500-grit sandpaper. Do not use sandpaper with a lower grit, or you will likely carve noticeable scars into the finish. Do not overdo it. Lightly scour the paint until the sheen appears duller.
Dampen a soft sponge. Ensure that the sponge is clean and free from trace oils and cleanser residues.
Wipe the sanded painted finish with the sponge. Dry the paint with a towel.
Repaint With Low-sheen Paint
Abrade the glossy painted finish or the new, less-glossy paint won't adhere. Scour the glossy paint with 100-grit sandpaper until the existing finish feels slightly rough.
Place drop cloths beneath the existing glossy finish. Attach painter's masking tape to adjacent surfaces.
Apply a particular type of paint based on your personal taste. For a low, muted sheen, apply eggshell or stain paint. For no sheen at all, apply a flat paint. Apply the paint using a roller. Roll vertically while applying gentle pressure. Touch up the surface as needed, using a polyester brush. Let the new finish dry for at least 2 hours.
