The Look of Enamel
When I think of the word “enamel” a vision comes to mind of a beautifully smooth brushless glossy surface. The word is now commonly used for a variety of paint types, and I’ll avoid getting too technical here – as I’d rather focus on the point of this article – which is how to customize fine art acrylic paints to create a brushless, smooth and glossy surface.
Definition from Wikipedia
“… the term “enamel paint” is used to describe oil-based covering products, usually with a significant amount of gloss in them, however recently many latex or water-based paints have adopted the term as well. The term today means “hard surfaced paint” and usually is in reference to paint brands of higher quality, floor coatings of a high gloss finish, or spray paints. Most enamel paints are alkyd resin based….” view Wiki’s full article
5 ways to get this look
Painters can obtain an “enamel” appearance using any of these five methods, along with fine artist’s quality acrylic paint.
Method 1. Use thin paints
Start with a paint that is naturally or formulated in a thin consistency: Use the fluid acrylic paints that come in bottles, or the new super thin (but with highly saturated color) High Flow acrylic paints. Thinner consistency paints offer a smoother application with less visible brushstrokes or texture. The thick acrylic paints that come in tubes and jars have thickener added to them to look and act like oil paint. These are great for adding texture, but will take more effort on your part to get them to look smooth. By using the Fluid or High Flow paints you still have strong color, but won’t
Method 2. Change your paint
Customize your paint by adding thin mediums to make a thinner color mixture: Add to your paint color some hard, clear mediums like Golden’s GAC500 or GAC100. These can be added to thick paints to help thin them, although the color will become less intense, so if possible use thin paints to start with as stated previously. Adding these mediums to your Fluid or High Flow paint colors will make them harder and glossier, increase refraction and increase leveling capabilities. Additionally add up to 15% retarder to this mixture to slow down drying, enabling even smoother applications.
Method 3. Apply paint smoothly
Position brush properly for smooth applications: Apply paint or mixtures onto your surface using a soft wide flat brush, spreading thinly by working in small areas at a time. Keep brush positioned at a low angle to your surface for smooth applications, instead of a 90 degree angle or perpendicular to the surface which will create more texture.
Method 4. Layer the Paint
Alternate layers of paint with medium: Another option is to first apply a thin layer of pure paint color undiluted onto your surface and let dry. Do not add any water or medium to the paint color. If using a thicker paint sand smooth after drying. Over this dried paint color layer, brush apply a thin layer of GAC500 (or any thin undiluted gloss acrylic medium). Let dry. Repeat by applying another layer of paint color, then another layer of medium. Repeat as many times as you like, waiting until each application or layer is dry before applying the next. By building up in layers alternating between paint and medium you can achieve a very smooth brushless highly refractive surface. If your paint color layers are holding brush strokes you can lightly sand each layer when dry with waterproof sandpaper, using water to keep any sanded particles from getting airborn. Wipe off the sanded areas while still wet with a soft rag.
Method 5. Pour the paint
Add some paint color to a glossy pouring medium, and apply onto your surface by pouring. This eliminates brushstrokes and easily creates the perfect enamel look. Spray the freshly poured layer lightly with alcohol immediately after pouring and while still very wet to eliminate bubbles.
