Effects and Mediums


Typically, when the paint lifts from the surface while removing the foil layer or burnishing the foil, there is an issue with the actual basecoat of paint’s adhesion to the surface below the Leaf & Foil Size. If the paint doesn't fully stick to the surface, the pressure of rubbing and pulling during foil application can essentially peel off the paint. This most often occurs when the surface below the Size and the basecoat paint are glossy, lacquered, slick, or waxed. The best way to avoid the basecoat of paint lifting is to make sure the paint is fully hardened/cured to the surface before Leaf and Foil Size application or prime/sand any surface that may be a bit slick/glossy before applying the basecoat of paint.

If you’re able to easily pull/peel up the foil from the surface: Lift the foil off the surface, re-exposing the Leaf and Foil Size layer. If you’re not able to easily pull/peel up the foil from the surface: Using a precision cutting tool like an Exacto knife or razor blade, find an edge of the foil and gently try to pry the foil from the Size. Rubbing Alcohol on a Q-tip may help soften the Size adhesive as a last resort. 

Re-apply Size if needed and apply foil. Remember, foils should be applied shiny side (color) face up. 

When pulling off the foil, some Size and paint may pull off due to the extra strength bonding of the Size medium. If sticky Size comes off or bubbles, patch the missing areas with more Size. If paint lifts, depending on the severity of the paint lift, some touch up paint maybe required. If areas are small: touch-up with paint and reapply Size. If paint needs to be removed and the entire surface repainted: To remove old Size and paint from the surface, use a chip brush dipped in rubbing alcohol to soften the Size adhesive. Next, sand off the Size and paint. Then repaint and reapply Size. Make sure the alcohol residue is completely evaporated and removed from the surface prior to repainting.

Yes. Once Leaf and Foil Size has been applied to a surface it remains tacky indefinitely if not sealed. Seal metallic surfaces with Artisan Enhancements™ sealers Clear Topcoat or Clear Finish. For dusted foils we recommend a “Matte” sheen of our sealers. For glossy foils we recommend a “Gloss” sheen for our sealers. If using traditional metal leaf, do a sample piece to determine the desired sheen.

Note: Wax and Scumble glaze maybe used over foiled surfaces. To add an additional layer of wax or Scumble glaze, first seal the foiled surface with one thin coat of Clear Topcoat sealer. Allow the surface to cure a minimum of 72 hours before wax or Scumble application – for best results allow 1 week of Clear Topcoat cure time before wax or Scumble application. Follow wax manufacturer’s instructions for wax applications. Follow Scumble Tip Sheet for Scumble application.

Use hand sanitizer to remove “tackiness” from hands and fingers. Use rubbing alcohol to remove sizing from tools and stencils. After cleaning with rubbing alcohol rinse with warm water to remove any remaining alcohol residue.

Yes! Scumble can be used as a slip coat for blended and dry-brush techniques. However (depending on the formula of the basecoat of paint), occasionally Scumble can re-wet and re-open painted layers with the reintroduction of moisture leading to muddy and inconsistent glaze applications. For best results, make sure the basecoat of paint is completely dry before the application of Scumble. If you’re nervous about the paint re-opening, seal the painted surface with Artisan Enhancements™ Clear Topcoat prior to the Scumble application. We always recommend doing a test piece of your Scumble technique to see how the basecoat responds.

To use Scumble as a slip coat before paint application, apply a thin coat of Scumble to a dry pre-painted (basecoat) and sealed surface. While Scumble is still wet, apply paint over the Scumble layer. Use a brush or sea sponge to blend, soften, and manipulate the paint. To learn more about Scumble techniques and dry times review the comprehensive Tip Sheet.

Yes. Once fully dry, we recommend sealing all Scumble applications with Artisan Enhancements™ sealers. If the Scumble technique is left unsealed it can re-open and re-activate if exposed to moisture. Note: Wax maybe used over surfaces with Scumble Glazes. To add an additional layer of wax, first seal the surface with one thin coat of Clear Topcoat sealer. After 72 hours of dry-time, additional colored waxes can be layered over the Clear Topcoat sealed surface. Follow wax manufacturer’s instructions for wax applications.

Scumble is a translucent water-based effect medium. Scumble was developed to be worked and manipulated into the surface. Due to the performance properties and application method, occasionally (depending on the formula of the basecoat of paint) Scumble can re-wet and re-open painted layers readily with the reintroduction of moisture leading to muddy and inconsistent glaze applications. For best results, if painting before application, make sure the basecoat of paint is completely dry before the application of Scumble. If you’re nervous about the paint re-opening, seal the painted surface with Artisan Enhancements™ Clear Topcoat prior to the Scumble application. We always recommend doing a test piece of your Scumble glaze to see how the basecoat and tinted glazes respond.

Yes! Scumble can be used to extend open-times (to keep paint from drying out on larger surfaces) and as a leveler (to improve flow and help reduce brushstrokes) for water-based paints. Add 5% by volume Scumble to paint to extend. If using a Scumble + Paint mixture, allow the surface to dry overnight before recoating or sealing.

Yes! Scumble can be tinted with a variety of pigment sources including universal tint systems, water-based paints, and mineral pigments. To tint Scumble: Start with a 3:1 ratio (3-part Scumble to 1-part tint/paint/pigment). Add tint source to Scumble glaze medium. Stir mixture thoroughly to combine. Test on a sample piece. To learn more about tinting Scumble review the comprehensive Tip Sheet.

Yes. Seal with Artisan Enhancements™ sealers or wax.

Note: If creating a multi layered finish - adding more layers of paint, plaster, glaze, or a color wash - once crackle layer of paint is dry, a thin layer of Artisan Enhancements™ Clear Topcoat may be needed to protect the crackle paint/plaster layer from reopening with moisture.
