Long before aerosol cans existed, artists were fixing charcoal and graphite with milk, shellac and plant gums blown through a little hinged tube called a mouth atomizer. Those recipes still work, after a fashion. A DIY fixative for pencil drawings can hold graphite in place for practice work and sketchbooks, but every homemade option has a weak spot: uneven spray, water damage, yellowing, or spoilage. This guide gives the main recipes with ratios, explains what commercial fixative is actually made from, and is honest about where homemade versions fall short.
Quick answer: The most practical DIY fixative for pencil drawings is a thinned acrylic matte medium (about 1 part medium to 4 parts water, with a splash of isopropyl alcohol) sprayed as a fine mist. Traditional options include skim milk, dewaxed shellac thinned heavily in denatured alcohol, and diluted gum arabic. All of them need a very fine mister, light coats and testing on scrap. They suit practice work; for finished drawings, a commercial fixative is more even and more predictable over time.
What Is Drawing Fixative Spray Made From?
Understanding the commercial product makes the homemade versions easier to judge. Any fixative has three parts.
- A binder (resin). This is the part that glues particles to the paper. Modern fixatives typically use synthetic resins such as acrylics. Historically, artists used casein (from milk), shellac, damar, mastic, gelatin and plant gums.
- A carrier (solvent). The resin is dissolved or dispersed in a liquid that evaporates quickly, such as alcohols, acetone or hydrocarbon solvents in commercial products, or water and alcohol in many homemade ones.
- A delivery method. Aerosol propellant atomizes the liquid into very fine droplets. This is the part home recipes struggle to match, and it matters more than the recipe itself.
The most important point: the binder must be applied as a fine, dry-ish mist. Large wet droplets soak the paper, shift graphite, cause spots and can buckle the sheet. That is why a mediocre recipe through a fine sprayer often beats a good recipe through a coarse one.
It is also why aerosol fixatives remain the benchmark. If you want to see how purpose-made formulas differ in resin, finish and UV protection, our comparison of fixative sprays for graphite and pastel lays them out side by side.
Equipment for Homemade Fixative
- Fine-mist sprayer. A continuous-mist bottle, the kind sold for hair styling or plant misting, gives far finer droplets than a standard trigger bottle.
- Airbrush (optional, best results). An airbrush with a 0.3–0.5 mm nozzle gives the finest, most controllable mist of any home method.
- Mouth atomizer (optional, traditional). A small hinged metal tube: one end sits in the liquid, you blow through the other, and the airflow pulls up and atomizes the fixative. It is inexpensive and works surprisingly well with thin liquids.
- Measuring cups and spoons reserved for art use.
- Coffee filter or fine mesh for straining.
- Funnel and labeled bottles for storage.
- Scrap paper with pencil marks on it for testing.
- Ventilation for any alcohol-based recipe, plus distance from flames.
Recipe 1: Thinned Acrylic Matte Medium (Most Practical)
Acrylic matte medium is the same type of binder used in acrylic paint. Thinned, it forms a clear, flexible, fairly stable film. Many artists consider this the most reliable homemade option.
Ingredients
- 1 part acrylic matte medium (fluid medium mixes more easily than gel)
- 4 parts distilled water
- About 1 tablespoon isopropyl alcohol (70–91%) per cup of mixture, optional
Steps
- Mix (3 minutes). Stir the medium into the water slowly until fully dispersed. Avoid shaking hard, which creates foam.
- Add alcohol (1 minute). The alcohol lowers surface tension and speeds drying, which reduces how much the paper absorbs. Start with less and add more if it beads on the test sheet.
- Strain (2 minutes). Pour through a coffee filter to catch any lumps that could clog the sprayer.
- Test (10 minutes). Spray a scrap with pencil marks from about 12–18 inches away. Let it dry and check for spots, sheen and cockling.
- Apply (5 minutes per coat). Mist lightly in sweeping passes, starting and ending off the paper. Let each coat dry fully, about 10–20 minutes, before adding another. Two light coats are usually plenty.
Strengths: Clear, flexible, generally non-yellowing film; acrylic binders are widely used in permanent artwork. Limits: Water-based, so paper may cockle if over-applied; can leave a slight sheen if too concentrated; clogs fine sprayers if left to dry in the nozzle. Shelf life: Several weeks in a sealed bottle. Discard if it smells sour or develops lumps.
Recipe 2: Skim Milk Fixative (Traditional, Cheapest)
Milk contains casein, a protein that acts as a binder when it dries. Skim milk is used because fat can leave greasy patches. This is one of the oldest fixative methods and is still taught as a historical technique.
Ingredients and steps
- Use fresh skim (fat-free) milk. Some recipes thin it with an equal amount of water for lighter graphite work.
- Pour it into a fine-mist sprayer or use it with a mouth atomizer.
- Spray one very light coat from about 12 inches. Let it dry fully, about 15–30 minutes.
- Add a second light coat only if graphite still transfers.
- Rinse the sprayer immediately with warm water.
Strengths: Costs almost nothing, has no solvent fumes, and is easy to find. Limits: Milk is a food product. Over-applied, it can smell, attract insects or encourage mold, especially in humid storage. It can leave a faint yellowish or blotchy cast on white paper. It also adds water, so cockling is possible. Mix a fresh batch each time; never store leftover milk fixative.
Recipe 3: Shellac and Alcohol (Traditional Spirit Fixative)
Shellac dissolved in alcohol was a standard fixative for charcoal for generations. Because the carrier is alcohol, not water, it dries fast and does not cockle paper.
Ingredients
- Dewaxed shellac (clear or “blonde”), either pre-mixed liquid or flakes
- Denatured alcohol
Ratio and steps
- Thin heavily. If you start from a ready-mixed 2-lb cut liquid shellac, a starting point is about 1 part shellac to 8–10 parts denatured alcohol. The goal is a liquid barely thicker than plain alcohol.
- Stir and strain through a coffee filter.
- Spray outdoors with a fine mister or airbrush, from 12–18 inches, in very light passes.
- Allow 10–15 minutes between coats.
- Clean equipment with denatured alcohol right away.
Strengths: Fast-drying, no cockling, strong hold for charcoal. Limits: Shellac tends to amber and darken with age, which shows on white paper. It can turn whitish in humid conditions. Denatured alcohol is flammable and the fumes need strong ventilation. Mixed shellac also has a limited shelf life; old shellac may stay tacky.
Recipe 4: Diluted Gum Arabic
Gum arabic is the binder in watercolor paint. Thinned with water, it can fix light graphite.
- Mix about 1 part liquid gum arabic with 10–15 parts distilled water.
- Stir well and strain.
- Mist very lightly; one coat is often enough for light graphite.
- Dry flat for 20–30 minutes.
Strengths: Inexpensive and non-toxic in ordinary use. Limits: Gum arabic stays water-soluble, so any later moisture can reactivate it. Heavier coats leave a slightly glossy, brittle film and can make paper buckle. It is best for sketchbook pages rather than finished work.
DIY Fixative Recipes Compared
| Recipe | Carrier | Paper cockling risk | Yellowing risk | Odor and fumes | Best use |
|---|---|---|---|---|---|
| Thinned acrylic matte medium | Water plus alcohol | Moderate | Low | Low | General graphite, sketchbooks |
| Skim milk | Water | Moderate | Moderate | None, but can sour | Practice work, historical technique |
| Shellac and alcohol | Alcohol | Low | High over time | Strong; flammable | Charcoal studies |
| Diluted gum arabic | Water | Moderate to high | Low to moderate | None | Light graphite in sketchbooks |
| Commercial art fixative | Solvent plus propellant | Very low | Low (in non-yellowing products) | Strong; ventilate | Finished, archival work |
Application Technique That Makes Any Recipe Better
- Prepare the drawing. Brush off loose graphite and eraser crumbs. Anything loose gets glued down.
- Tape the drawing to a board on all four edges. This limits cockling with water-based recipes.
- Lay it flat for water-based fixatives to prevent drips; upright at a slight lean is fine for alcohol-based ones.
- Prime the sprayer off to the side so the first coarse burst does not land on the drawing.
- Keep moving. Sweep steadily, overlapping passes by about a third, and never pause over the paper.
- Go lighter than feels right. The surface should look misted, not wet. If you see shine from pooling, you have applied too much.
- Dry completely between coats, and leave the drawing taped down until fully dry to keep it flat.

Storing and Labeling Homemade Fixative
Homemade mixes do not carry the stabilizers or sealed packaging of commercial cans, so storage makes a real difference to how long they stay usable.
- Label every bottle with the recipe, ratio and date mixed. Clear liquids look alike, and spraying shellac when you expected acrylic medium can ruin a drawing.
- Use opaque or amber bottles for shellac, which degrades faster in light.
- Keep alcohol-based mixes tightly capped and away from heat; the alcohol evaporates and the remaining liquid becomes thicker and sprays poorly.
- Refrigerate nothing you would not want next to food. If you mix a small batch of milk fixative, use it the same day and pour the rest away.
- Clean sprayers after every session. Run warm water through for water-based mixes and denatured alcohol for shellac. Dried binder in the nozzle is the most common reason a homemade sprayer starts spitting.
- Retest after storage. A mix that worked last month may have thickened or separated. Spray a scrap before every use.
What Not to Use as a DIY Fixative
- Household clear-coat sprays designed for furniture or crafts: often glossy, heavy and not made for paper, with a risk of yellowing.
- Glue diluted with water (PVA school glue): can work in very dilute form, but tends to leave a shiny, uneven film and is hard to spray finely.
- Sugar water: sticky, attracts pests and stays humidity-sensitive.
- Whole milk: the fat leaves greasy marks.
- Hairspray on work you want to keep: convenient, but full of fragrance, conditioners and other additives meant for hair rather than paper.
Honest Limits of Homemade Fixative
Homemade fixatives fall short of commercial ones in a few consistent ways.
- Spray quality. Even good misters produce larger droplets than an aerosol, which raises the risk of spots and uneven tone.
- Water content. Most homemade options are water-based, and water is what makes paper cockle and graphite shift.
- Unknown aging. Commercial fixatives often state non-yellowing or archival properties. Homemade mixes come with no such information, and some traditional binders, especially shellac and milk, are known to discolor.
- Consistency. Batch to batch, ratios and results vary.
That does not make DIY pointless. For sketchbooks, studies and learning, it is a cheap, low-fume way to stop smudging. For work you plan to frame, sell or keep for decades, a purpose-made archival fixative is more predictable.

FAQs
What is the best homemade fixative for pencil drawings?
Thinned acrylic matte medium, about 1 part medium to 4 parts water with a little isopropyl alcohol, is generally the most practical. It forms a clear, flexible film with low yellowing risk, provided you mist it very lightly.
Does milk really work as a fixative?
Yes. The casein protein in skim milk acts as a binder and has been used for a long time. It can leave a faint cast, may sour or attract mold if over-applied, and adds water that can cockle paper, so it suits practice work best.
What is drawing fixative spray made from?
Commercial fixative combines a resin binder, often an acrylic, with a fast-evaporating solvent and an aerosol propellant. Historical fixatives used binders such as casein, shellac, damar and plant gums dissolved in water or alcohol.
Will homemade fixative yellow my drawing?
It depends on the binder. Shellac is known to amber over time, and milk can discolor. Acrylic-based homemade fixative is less likely to yellow. No homemade mix carries an archival rating, so results over decades are uncertain.
Can I use a regular spray bottle for DIY fixative?
A standard trigger bottle sprays droplets that are usually too large and wet. A continuous fine-mist bottle, an airbrush, or a mouth atomizer gives much better results.
Is DIY fixative safe to use indoors?
Water-based recipes like milk, gum arabic and thinned acrylic medium have little odor, though ventilation is still sensible. Alcohol-based recipes such as shellac are flammable and give off fumes, so use them outdoors or with strong ventilation, away from any flame.
