Quick answer: To make resin art on canvas, seal and level a rigid canvas, mix a two-part art epoxy resin exactly as the label directs (commonly equal parts by volume) for about three minutes, tint it with pigment or alcohol ink, pour and spread it over the surface, pop bubbles with a quick pass of heat, and leave it covered and level for 24 to 72 hours to cure. Wear gloves and a suitable respirator, and work in a ventilated room.
Resin art has a glossy, glass-like finish that makes color look deep and liquid. It has a reputation for being tricky, and it is true that resin is less forgiving than acrylic paint: it will not wait for you to change your mind, and mistakes harden in place. But the process is quite predictable once you understand the sequence of preparing the surface, mixing carefully, pouring, controlling bubbles and curing without dust.
This guide to how to make resin art on canvas explains each stage in order, including the materials, safety, measuring and mixing, color techniques, finishing and the problems beginners meet most often. If you are still choosing a support, the guide to the best canvas for resin art explains why rigidity and sealing matter so much.
What Is Resin Art?
Resin art uses a two-part liquid, usually epoxy resin and hardener, that cures into a hard, clear plastic. Artists tint it with pigments, mica powder, alcohol inks or paints, then pour it onto a surface and guide it into patterns such as ocean waves, geodes, marble swirls and flowing abstract fields. The result is a thick, shiny layer, often compared to glass.
For canvas, artists commonly use art or “tabletop” epoxy resin formulated for coating, because it self-levels and cures clear. It is different from casting resins used for deep molds and from UV resin used for small jewelry pieces.
Safety First
Resin is a chemical product. Read the manufacturer’s safety data and instructions, and follow them over general advice.
- Gloves: Use nitrile gloves. Do not touch uncured resin with bare skin.
- Respirator: Use a respirator rated for organic vapors if the product label recommends it.
- Ventilation: Work in a well-ventilated area, ideally with a fan pulling air away from you.
- Eye protection: Wear safety glasses.
- Clothing: Wear old clothes or an apron with long sleeves.
- Keep away from children and pets during mixing and curing.
- No open flames near products unless the label says it is safe. Use a heat gun or the method recommended by the product instead of a torch if you are unsure.
- Disposal: Do not pour resin down the drain. Allow leftover mixed resin to cure in its container, then dispose of it as the label advises.

Choose the Right Canvas
Canvas choice matters more with resin than with paint. Resin is heavy, and a thin stretched canvas can sag in the middle, creating a pool and an uneven finish. Look for:
- A rigid support such as a cradled panel or canvas board, or a stretched canvas with a deep, braced frame
- A flat, even surface with no warping
- A size you can pour comfortably, such as 8 by 10 to 16 by 20 inches for a first piece
If you plan to practice before committing to a final piece, use an inexpensive panel or board first.
Step-by-Step: How to Make Resin Art on Canvas
Step 1: Prepare the workspace
Choose a level, protected surface in a room around 70 to 77 degrees Fahrenheit. Cool rooms make resin thick and bubbly, while hot rooms shorten the working time. Cover the table with plastic. Place small cups or blocks on the table and rest the canvas on top so the edges hang clear and drips can fall without gluing the canvas to the surface. Check with a level and adjust with shims until the surface is flat.
Step 2: Prepare the canvas
Tape the back and sides if you want clean edges, or plan to catch drips and sand them later. If your canvas is untreated, apply a seal coat of acrylic paint, gesso or a thin layer of resin to stop the canvas from absorbing resin and releasing air bubbles. Let the base layer dry fully. If you want to paint a background first, do it with acrylics and let it dry completely before pouring resin.
Step 3: Measure the resin accurately
Resin only cures properly if the ratio of resin to hardener is correct. Most art epoxies use equal parts by volume, but some use different ratios or measure by weight, so check your product. To estimate how much you need, multiply the length and width of the canvas in inches and divide as the manufacturer suggests for a coating thickness of about 1/8 inch. A small canvas needs only a few ounces.
Measure into one cup, then pour the correct amount into a second clean cup. This helps reduce errors from leftover residue.
Step 4: Mix thoroughly
Combine the resin and hardener, then stir slowly for about three minutes, or the time the label specifies. Scrape the sides and bottom of the cup and stir again. Stirring slowly reduces bubbles. Under-mixing leaves sticky patches that never cure. Some people pour the mixture into a second cup and stir again, which helps catch unmixed resin.
Step 5: Add color
Divide the mixed resin into small cups and add a tiny amount of pigment to each. Common colorants include resin pigments, mica powders and alcohol inks. Add pigment in small amounts, because too much can affect curing. Typically, colorants should make up only a small portion of the total volume, so follow the product’s guidance.
Alcohol inks create lacing and cell effects when added to resin or dropped onto the surface. The guide to the best alcohol inks explains how they behave and what to look for.
Step 6: Pour the resin
Begin with a base color and pour it over the canvas. Add other colors in streaks, puddles or swirls. Tilt the canvas gently or use a gloved hand or a spreader to move resin toward the edges and over the sides. Work quickly but calmly, because you have a limited working time, often 20 to 45 minutes depending on the product.
Step 7: Create patterns
Choose a technique and keep it simple on your first pour.
- Puddle pour: Pour several colors in separate puddles and tilt gently so they flow together.
- Dirty pour: Combine colors in one cup, then pour all at once.
- Swipe: Drag a spreader across the surface to create smooth streaks and cells.
- Ocean waves: Pour blue and teal, add a white band for foam and use a heat gun lightly to push the white into lacing.
- Geode: Paint a geode shape, pour translucent resin and add glitter or crystals along the edges.
Step 8: Remove bubbles
Pass a heat gun or torch quickly over the surface, holding it several inches away and moving constantly. Bubbles rise and pop. Do not hold heat in one spot, which can scorch the resin. If using a torch, follow safety instructions and do not use it near flammable materials.
Step 9: Check the sides and drips
Run a gloved finger or stick along the underside edges to smooth drips, or leave them to be sanded later. Check for sagging and add more resin to thin areas if needed during the working time.
Step 10: Cover and cure
Cover the canvas with a box or a tent that does not touch the surface. This keeps out dust and hair. Leave it undisturbed on a level surface for the time given on the label. Resin often becomes tacky to touch within 12 to 24 hours and reaches full hardness in about 72 hours, but times vary by product and room temperature.
Step 11: Finish
After curing, peel off tape, sand away dried drips on the sides and wipe dust. If the surface has flaws, you can sand lightly and add a thin second coat of resin, called a flood coat, to restore the gloss.
How Much Resin Do You Need?
Running short mid-pour is one of the most common beginner problems, so do the math first. Multiply the canvas length by the width (in inches) to get square inches, then multiply by the coating thickness you want. Many art coats are about 1/8 inch (0.125). One fluid ounce is roughly 1.8 cubic inches.
| Canvas size | Area | Volume at 1/8 inch | Approx. mixed resin |
|---|---|---|---|
| 8 x 10 in | 80 sq in | 10 cu in | About 5.5 fl oz |
| 12 x 16 in | 192 sq in | 24 cu in | About 13 fl oz |
| 16 x 20 in | 320 sq in | 40 cu in | About 22 fl oz |
| 24 x 36 in | 864 sq in | 108 cu in | About 60 fl oz |
Add roughly 10 to 20 percent extra to cover the sides and loss on the cup and tools. Divide the total by two if your product mixes at 1:1 to find how much resin and how much hardener to measure. A surface that is not perfectly sealed may soak up more, so a spare allowance helps. The canvas sizes and prep advice in the resin art canvas buying guide make planning easier.
Common Problems and Fixes
Sticky or soft areas
Usually caused by incorrect ratios, poor mixing or low temperature. Scrape off small areas if possible, or cover with a new layer of resin after cleaning.
Bubbles in the cured piece
Mix more slowly, warm the resin bottles in a warm water bath before mixing, and pass heat over the surface soon after pouring. Seal the canvas to reduce bubbles from trapped air.
Dust or hair in the surface
Cover immediately and work in a clean area. Remove surface debris early with a toothpick while the resin is still wet.
Cloudy resin
Often caused by moisture, cold or too much pigment. Work in a dry, warm room and use pigments made for resin.
Canvas sagging
Use a rigid support. Prop the center from underneath if needed.
Colors turn muddy
Avoid overmixing colors on the canvas. Pour distinct colors and let them flow together.
Resin runs off unevenly
Check that the surface is level and pour slightly more than you think you need.
Tips for Beginners
- Do a small test pour before the real piece.
- Read the resin instructions in full before starting.
- Mix more than you think you need, since running out mid-pour is hard to fix.
- Keep paper towels and extra gloves within reach.
- Start with two or three colors.
- Keep a timer for mixing and working time.
- Work at a comfortable temperature and let the resin warm up if it is cold.
Caring for a Resin Canvas
- Dust with a soft cloth and clean with a damp one if needed.
- Avoid direct sun for long periods, since some resins can yellow over time.
- Do not hang in very hot places.
- Handle by the edges and avoid sharp objects.
FAQs
How do I start making resin art?
Begin with a small rigid canvas, a quality art epoxy resin kit, pigments and basic safety gear. Practice a simple pour before attempting complex techniques.
Do I need to seal a canvas before resin?
Yes, usually. Sealing with gesso, acrylic paint or a thin resin coat helps prevent absorption and bubbles.
What ratio do I use for epoxy resin?
Many art epoxies use a 1:1 ratio by volume, but follow your product’s instructions exactly.
How long does resin take to cure?
Most resins become tacky to touch in about a day and fully cure in a few days. Check the label for your specific product.
Can I use acrylic paint with resin?
Yes, on the canvas beneath the resin, as long as it is fully dry. Small amounts of acrylic can also be mixed in some resins, but it can affect clarity and curing, so test first.
How do I get rid of bubbles in resin?
Mix slowly, seal the surface, and use a heat gun or torch quickly over the poured resin.
