# Oil painting: brush handling and paint application

**How to use this skill:** It adds specialist tips to your answer. It does not replace your answer. Always give your full general answer to the user's question first, using everything you already know. Then work in the tips below wherever they apply. Do not drop general advice just because a tip covers the same topic.

## When to use medium and the palette knife
- Add medium only when paint doesn't come off the brush easily. Most tube paint is already the right consistency.
- Don't thin so far that the paint looks pale and watery unless a glaze is wanted. Oil paint should normally look solid and cover the canvas.
- A "glaze" is paint thinned with enough medium to be transparent.
- Pick up and apply paint with the bottom (underside) of the palette knife blade, never the top, like a trowel or frosting spatula. Keep the knife clean.
- If paint comes out of the tube with extra oil, put it on a paper towel with the knife to absorb the excess, then move it to the palette.

## Mixing medium and setting up cleaners
- Medium recipe: half linseed oil and half odorless mineral spirits or a turpentine substitute such as odorless Turpenoid.
  - Put a masking-tape mark halfway up a lidded glass jar.
  - Fill to the mark with linseed oil, then to the top with the solvent.
  - Tip the jar back and forth. Do not shake it.
  - Label the jar "medium".
- Water-mixable oils skip this recipe. Use water-mixable linseed oil medium instead.
- Use two small wide-mouthed containers. Mark one "M" (medium) and one "C" (cleaner).
  - M gets about 2 tablespoons of medium.
  - C gets about ½ inch of Turpenoid Natural.
- For water-mixable oils, M gets about 2 tablespoons of water-mixable linseed oil medium, and the cleaner is a large container of water.
- Keep the large stock containers of medium ingredients and brush cleaner out of the way.

## Palette
- Use a purchased paper palette, or cover a 12 × 16-inch piece of cardboard with freezer paper, shiny side up, secured with masking tape.
- Put paint around the edges, with space between colors and maximum free space in the middle for mixing.
- Replace tube caps immediately so they don't get lost.

## Workspace layout
- Put a tabletop easel directly in front of you with nothing in front of it. That space is for resting your painting arm, which gives precise control.
- Keep anything with wet paint out of that space. Don't put the palette there, because reaching over it smears paint on your stomach and the painting.
- Put the palette to the side of the easel nearest your painting hand. Keep medium and cleaner nearby, e.g. behind the palette.
- Keep paper towels or rags near your nonpainting hand. A tear-off stack with one sheet held in that hand allows quick wipes. Have a garbage receptacle nearby.
- Keep a small coffee can or jar for resting brushes, handles down.
- Never lay brushes on the palette. They roll into the paint.
- Choose or adjust a chair so you can reach the painting without strain. A cushion helps.
- Odorless solvents like Turpenoid Natural make it practical to set up in a kitchen corner, patio, or garage.

## Choosing paint thickness
- **Very thin** (thinned with medium): used for underpainting, glazing, and fine lines.
- **Solid but smooth coverage:** the paint doesn't rise above the canvas surface. It is good when you'll paint over the layer while still wet, and for superrealistic styles with no visible brushwork.
- **Visible brushstrokes:** a perceptible layer that rises above the surface.
- **Impasto:** thick ridges. Take care with it because of the danger of cracking.

## Seasoning and loading the brush
- Season a brush before use by dipping it in medium, then wipe it dry. This coats the bristles and makes cleanup easier.
- Never pull on the bristles while drying them, because they may come out.
- Season once at the start of each painting session.
- Do NOT season the hake brush or any brush used for blending. Use those dry.
- Paint with the width of the brush, not the edge, unless told otherwise.
- Load the brush by pulling paint from the edge of a daub. Don't dip into the middle of the daub.
  - Dipping a blue-loaded brush into the center of white paint contaminates the white and costs you clean color.
- After loading, rub the brush gently side to side on the palette to spread the paint evenly across the brush edge.

## Basic strokes
- **Flat stroke** (smooth, no visible strokes):
  - Use a seasoned #6 flat bristle brush and the wide side to cover a 2-inch square with a solid, smooth layer.
  - Add stripes of other colors and blend them while keeping the application flat.
  - Soft sable flats and filberts are ideal for this.
- **Edge-of-brush stroke:** turn the brush to make lines with its tapered edge.
  - Newer brushes give sharper edges than older ones.
  - Sable or synthetic sable gives sharper edges than bristle.
  - An angled shader also makes good lines.
- **Impasto:**
  - Load a lot of paint on a seasoned #2 flat bristle brush and use thick, short strokes so the paint stands up in ridges.
  - Place other colors side by side without blending so the strokes stay sharp and distinct.
- **Flip-flop stroke** (backgrounds, woven surfaces, fast filling of large areas):
  - Season a #10 flat bristle and load both sides with a light color.
  - Paint a straight diagonal stroke about ¾ inch long.
  - Turn your hand thumb up and draw the next stroke at a right angle.
  - Repeat to fill a 3-inch square.
  - Clean the brush, load both sides with a darker color, and work it into the lighter area with the same stroke. Few strokes give distinct chips of color. More strokes blend them.
- **Stipple / pounce** (distant grasses, wood or shell texture):
  - Use a large stiff brush such as a #10 flat bristle or a utility brush.
  - Plunge the brush head-down into the center of a daub of dark paint and pull it straight up without disturbing the paint on it. Tap it on the palette to remove excess.
  - Tap straight down onto the canvas and lift straight up, with no stroking, until the paint runs out. The imprint changes as the brush empties.

## Dry brush and scumbling
- Both techniques drag fresh color over a dry, painted layer so some of the underlayer shows through.
- Use a dry (not seasoned) brush for dry brush on real paintings.
- Hold the brush in an overhand grip: four fingers on one side, thumb on the other. This lays color on lightly without digging into wet paint.
- Dry brush:
  1. Load the whole side of the brush from the edge of a daub.
  2. Rub it on the palette until almost dry.
  3. Lightly rub it on the surface with the broad side level with the canvas. The paint catches the surface weave and lets the color underneath show.
  - Uses: scratchy weathered wood, blending one color over another, adding light, a subtle contrasting overlay, softening an edge.
- Scumbling:
  - It is like dry brush but with more (thick) paint on the brush. Either a regular or an overhand grip works.
  - Lightly drag the loaded side over the surface so it skips and leaves irregular gaps.
  - It is useful for highlighting heavy impasto and textured underpaintings, where the scumble catches the ridges.
- Burnt Umber dries quickly. A lighter color can be scumbled over it a day or so later.

## Fine lines
- Three keys: use a brush with a fine point, dilute the paint to ink consistency, and paint with only the tip.
- Procedure for a dark fine line:
  1. Put a puddle of medium next to the paint and mix a little paint into it until it looks like ink.
  2. Load the brush fully and stroke the tip on the palette to reshape it.
  3. Hold the brush at a right angle to the canvas, not like a pencil, so only the tip touches.
  4. Keep the pressure light and even.
- Rest your arm on the table for control. Laying the canvas flat can help.
- Fine straight lines can also be made with the edge of an angled shader or another sharp-edged flat.
- Thin-to-thick lines: more pressure gives a wider line. For grass, hold the brush midway on the handle and press at the bottom of an upward stroke, releasing as you lift. Work quickly, lean and overlap the strokes.
- Thin light line on a dark color (don't thin to ink consistency, or it won't show):
  1. Paint a patch of dark color solidly but not too thickly.
  2. Load a pointed brush with white mixed with just enough medium that it comes off the brush.
  3. Paint the line however you can, ignoring thickness and unevenness.
  4. Cut it down to a thin, even line with a clean sharp-edged brush such as an angled shader.
  - If the underlying paint is dry, dampen the clean brush slightly with medium. This works over wet or dry paint.

## Blending and transitions
- **Hake brush:**
  - It is very soft, made for blending, and melts colors without smearing unless they are very thick.
  - Never season it. Use it dry.
  - Uses: softening background leaves to push them out of focus, melting spots on fruit or fish into the surface, blurring water reflections.
  - It is wide, so use just the corner on small areas.
  - Hold it with four fingers near the bristles and the thumb opposite, handle angled up between thumb and forefinger.
  - Keep the arm still and whisk gently back and forth with the wrist. Wipe on a paper towel if it picks up too much paint.
- **Smooth blend:**
  1. With a #10 flat bristle, paint a 2-inch stripe of one color. Clean the brush.
  2. Paint a touching stripe of another color.
  3. Wipe the brush dry, place it at the top half on each color, and stroke down repeatedly until blended.
- **Bumpy texture blend:**
  1. Use the corner of a #2 flat bristle to paint solid daubs in a 2 × 1-inch column.
  2. Clean the brush, leave a ¼-inch gap, and paint a second column in another color.
  3. Fill the middle ¼ inch with dabs of both colors, keeping them as separate as possible.

## Sgraffito
1. With a #10 flat bristle, apply a thin but solid layer of Burnt Umber in a 1½-inch square. Push the paint into the canvas weave so it has no perceptible thickness.
2. Use a palette knife to lay a smooth "frosting" of Yellow Ochre over the wet umber.
3. Scratch a design through the top layer with the most pointed brush handle you have, exposing the layer below.
- It can add fine lines more easily than painting them.

## Printing textures
- Materials: paper doilies, burlap, exposed corrugated cardboard, cheap hard paper towels, sponge, crumpled newspaper.
- Procedure:
  1. Use an overhand grip to load a smooth layer of paint on the side of a #10 brush.
  2. Rub the paint over the material so it lands only on the bumps.
  3. Press the material face down on the canvas, hold it firmly (movement smears the texture), and rub the back of your thumbnail over it.
- With a doily, lay a sheet of paper over it before rubbing.

## Glazing
- A glaze is paint mixed with lots of medium until transparent. For a lighter glaze, add more medium rather than white, which makes the glaze cloudy.
- Uses: tone down garish color, darken, brighten, fix "chalky" areas, add depth and transparency to water, enhance underpainting texture.
- Apply glazes over areas that are solidly dry to the touch, not sticky.
- Always glaze darker over lighter, or you get a haze.
- Use a soft brush and a light touch. Don't rub back and forth, or the underlayer may dissolve.
- Use your regular medium so all layers dry at a uniform rate.
- Avoid prepared fast-drying glazing mediums unless you fully understand them. Many require the painting to have dried at least six months.
- Never put something fast drying over something slow drying, because of the cracking danger.
- Wet techniques run. Use a fresh canvas laid flat.

## Spattering
- Setup:
  1. Mask areas you don't want spattered with paper towels (newspaper for directional spatter).
  2. Pour a small puddle of medium next to the paint.
  3. Use a large stiff brush (a #10 flat bristle or an old toothbrush) to mix a little paint into the medium.
  4. Load the brush with plenty of the mixture.
- Point the brush exactly at the target and run a finger or palette knife across the bristles.
- Directional spatter:
  - Use a big mop brush that holds a lot of thinned paint.
  - Snap the brush in the direction you want the spatter to travel. Use a wrist snap only, not the whole arm.
  - It suits crashing-wave spray.
  - Practice until you can control it before using it on a painting.
- Thinner spatter into a glaze (starry sky exercise):
  1. Paint a 3-inch square with a blue glaze, damp but not runny.
  2. Load a large brush with paint thinner (odorless Turpenoid or mineral spirits).
  3. Spatter the thinner into the glaze. It makes holes that reveal the color beneath, which works well over a contrasting color.
  4. Lift out lines with a pointed brush dampened with medium, e.g. a tree against the sky.
- Spattering thinner also works over a thoroughly dry underpainted color.

## Cleaning up
1. If the medium looks clean, pour it back for reuse. Discard dirty medium and paint residue safely.
2. Wipe paint from the brushes and rinse them in the cleaner (Turpenoid Natural). Press the bristles gently on the bottom of the can, then stroke back and forth so the cleaner reaches the inside.
3. Scrape off usable wet paint from the palette to save, or discard it. Discard the palette paper.
4. Let the cleaner settle, then pour off and reuse the clear portion. Discard sediment and dirty cleaner safely.
5. Wash brushes in mild soap and lukewarm water.
   - Work up suds by circling the brush in your palm.
   - Spread the bristles with your thumbnail or a stiff brush to reach the center and scrape out remaining paint.
   - Rinse, squeeze out excess water, and reshape the brush.
6. Store brushes handles-down in a coffee can, or lay them flat to dry.
   - Don't store wet brushes in a box where the bristles press against the sides and bend.
   - Avoid roll-up carriers, which bend the bristle edges.
7. Wash hands with ordinary soap and water. Use brush cleaner for paint under the nails.
8. Remove paint from clothes promptly with Turpenoid Natural, then fabric stain remover if needed. Turpenoid Natural is nontoxic and water soluble, so the clothes can go in a regular wash load.
- Check local rules on hazardous waste disposal. Don't store dirty rags in closed containers.

## Saving paint
- Plastic wrap (e.g. Saran Wrap) over the palette works poorly. Don't freeze a whole wrapped palette.
- Better: transfer usable paint to a smaller piece of palette paper, put it in a covered container, and freeze it. Alternatively use a plastic tray (like a small frozen-food tray) inside a freezer bag.
- Freeze special mixtures in plastic film canisters.
- If you keep the whole palette under plastic wrap, move usable paint to fresh palette paper next session. Little will still be usable.
- Don't use paint that has started to harden. The bond to the canvas forms during drying, so using it weakens the paint layer.
- Never start a session with a palette of dried or drying paint.
- Getting unsoiled paint back into a partly empty tube:
  - Pile paint into the opening with the palette knife, then rap the tube bottom on a table. Don't pound it.
  - Or hold the tube at the metal collar and at the bottom and pull apart with a twist to create a suction that draws paint in.
  - Only worth doing for expensive colors.
