SUBSTRATE AND SURFACE PREPARATION
SoFlat Matte Acrylics may be applied to any surface typically able to accept acrylic paints. Smooth substrates improve uniformity. Non-porous painting supports such as glass and metal may require additional preparation to improve overall adhesion.
ALWAYS stir before use. Separation may occur in some colours, which can alter performance, evenness and sheen. For the uniform paint application, use a soft, synthetic flat brush and apply paint as evenly as possible before setting up and drying.
Unevenly applied layers, as might occur when using a coarse bristle brush, may not completely level before drying.
Adding water up to 15% to thin the paint should not significantly impact adhesion; however, higher amounts of water will cause water sensitivity.
All waterborne GOLDEN paints and mediums should blend easily with SoFlat Matte Acrylics; however, most will compromise the matte finish. We recommend GOLDEN Super Matte Medium (Item # 3531) for extending colours to retain the matte consistency of SoFlat Matte Acrylics. Adding more than 25% (3:1 paint to gel medium) will noticeably increase gloss and reduce the opacity.
INCREASING WORKING TIME
To slow drying time, add GOLDEN Retarder (15% suggested maximum amount) or GOLDEN OPEN Thinner (25% suggested maximum amount) to maintain the matte quality of SoFlat Acrylics. Because these additives do not contain acrylic binders, caution should be used when adding them to paint – follow the guidelines specified on the label. Too much thinner or retarder in paint results in weaker paint layers that may also remain tacky.
GOLDEN Airbrush Medium and GOLDEN Satin Glazing Liquid may also be used with SoFlat Acrylics. Adding more than 25% medium (3:1 Paint to Medium) will increase gloss and reduce the opacity. Testing is suggested if maintaining the low sheen is critical.
Multiple Paint Layers – Additional paint layers may be applied as soon as the underlying layers are sufficiently dry. Multiple layers tend to increase gloss slightly.
Thick Applications – Product consistency dictates how thick paint layers can be. However, thicker layers are more prone to cracking as they dry. For this reason, we recommend applying multiple layers or incorporating a thick gel, such as GOLDEN Extra Heavy Gel Matte when a thick application is desired.
Products that can be blended with SoFlat Acrylics without a noticeable change of sheen:
- Super Matte Medium
- Light Molding Paste
- Fibre Paste
- Pumice Gel
- Crackle Paste
- Pastel Ground
- Color Pouring Medium Matte
Clean tools with soapy water immediately after use and avoid allowing the paint to dry in brushes or other tools.
