Tips for Perfect Pours

Mix Thoroughly: Stir paint and medium together until completely smooth with no streaks, but avoid creating bubbles.
Consistency Matters: Paint should flow like warm honey. Test by dripping from a stick - it should flow in a steady stream.
Add Silicone Last: Mix silicone oil into each color just before pouring to create cells. More oil means larger cells.
Level Your Surface: Use a level to ensure your canvas is perfectly flat. Unlevel surfaces cause paint to run unevenly.
Work Quickly: Once mixed, paint begins to dry. Complete your pour within 30 minutes for best results.
Protect Your Work: Cover finished pours to keep dust off while drying. Allow 24-48 hours before touching.

Frequently Asked Questions

Q

How much paint do I need for acrylic pouring?

For standard coverage, you need approximately 0.028 fl oz of paint per square inch at 1/16" depth. A 16x20 inch canvas requires about 9-12 fl oz of total paint mixture (paint + medium) depending on the technique and desired overflow coverage.

Q

What is the best paint to medium ratio for acrylic pouring?

The ideal ratio depends on your technique: Dirty Pour and Swipe use 1:1, Flip Cup uses 1:1.5, and Dutch Pour uses 1:2 (thinner consistency). Ring Pour and Puddle Pour typically use 1:1. Start with these ratios and adjust based on your paint brand and desired consistency.

Q

How many drops of silicone oil should I use?

Use 1-2 drops of silicone oil per fluid ounce of mixed paint. For a typical 16x20 canvas requiring 10 fl oz of paint, add 10-20 drops total. More silicone creates larger cells, less creates smaller cells. Add silicone last, just before pouring.

Q

What consistency should acrylic pour paint be?

Your paint mixture should flow like warm honey or melted ice cream. When lifted with a stirring stick, it should drip in a smooth, continuous stream without breaking into drops. Too thick and it won't flow; too thin and colors will muddy.

Q

Why do I need extra paint for overflow in pouring?

Paint needs to flow over the canvas edges to achieve full coverage and eliminate bare spots. The calculator adds 20% overflow to ensure paint reaches all edges and creates the signature drips on canvas sides that characterize fluid art.

Q

Can I reuse leftover acrylic pour paint?

Yes, store mixed paint in airtight containers immediately after pouring. It typically lasts 1-2 weeks. Remix gently before using, and check consistency as some settling may occur. Don't add fresh silicone to old mixture; use within a week for best cell formation.
