Essential Brush Techniques
Flat Wash
For large numbered sections, use your largest brush and apply paint in smooth, even strokes in one direction. Don't go back over partially dried paint — it creates streaks.
Detail Work
For tiny sections and edges, switch to your smallest brush. Load less paint (dip only the tip) and use short, precise strokes.
Blending Edges
Blending is optional. For a softer boundary, test two wet colors on a separate practice surface before altering the numbered canvas. Keep the supplied colors separate when you want to follow the reference image. Flat numbered areas do not require blending.
Color Management
- Choose a sequence: Dark-to-light is one option. Working from the top down or within a small area can also help keep your hand clear of wet paint
- Build coverage: If a number shows after drying, add another thin coat instead of flooding the area with paint
- Don't mix on the canvas: Use a separate palette if you want to blend colors
- Keep pots closed: Acrylic dries fast — open one pot at a time
Common Mistakes to Avoid
- Using too much water: This dilutes the paint and makes it transparent
- Rushing: Let an adjacent area dry before touching its edge unless you deliberately want the wet colors to blend
- Skipping the reference image: Check the reference photo to see how the final piece should look
- Pressing too hard: Gentle strokes preserve brush tips and prevent paint buildup
Finishing Touches
- Touch up: After the full painting is dry, check for any numbers still showing through and add a second coat
- Clean edges: Use your smallest brush to sharpen lines between colors
- Allow for drying: A dry surface can still have wet paint beneath it. Layer thickness and conditions affect drying; there is no verified 24–48-hour curing rule for these kits
- Finish coating (optional): Check compatibility, application and drying instructions for the exact coating you choose. Test on a separate painted sample; do not assume any clear spray gives verified UV protection
Display Your Finished Art
Once the paint is dry enough for the intended handling, plan the display. Framed catalog kits and Ready-to-Hang Custom kits are pre-stretched on wooden bars. No Frame canvases need a suitable mounting or framing method. Measure the finished canvas: 40 × 50 cm is about 15.7 × 19.7 inches, so a rounded 16 × 20 in label does not guarantee a precise fit. See our measured framing advice.

How Much Water Should I Use?
Keep water for rinsing brushes and blot before picking up the next color. Pre-mixed acrylic does not need activation with water. If it is too thick to spread, test a small portion with a drop at a time, as shown in our thick-paint guide. If it flows outside the shapes or dries transparent, avoid adding more water and build coverage after drying.
Clean wet paint from the brush when you stop. Mild soap and cool water, followed by a thorough rinse and reshaping, are supported by Winsor & Newton's brush-care guidance. Do not leave the tips pressed against the bottom of a water cup.
How Should I Store Paint and a Work in Progress?
Wipe pot rims, close lids fully and keep the numbered reference with the project. Store the supported canvas where it will not be rubbed or splashed. Do not fold or tightly roll a painted canvas. GOLDEN's drying notes distinguish surface drying from drying through the whole paint layer; they do not establish a fixed curing time for our kit paints.
