If you need interior latex paint in a container close to 20 liters, the EVOLVE 5-gallon options are the closest matches in this selection: 5 U.S. gallons equal about 18.9 liters. The EVOLVE Ultra White flat paint is best for broad wall coverage, while the Soft Violet satin paint suits buyers seeking a colored, subtly reflective finish. The other options are quart-size paints for smaller projects, trim, or moisture-conscious rooms—not substitutes for a bulk container.
| Product | Size and finish | Best for |
|---|---|---|
| EVOLVE Ultra White | 5 gallons, flat | Large interior wall projects |
| EVOLVE Soft Violet | 5 gallons, satin | Bulk painting with a colored satin finish |
| Krylon ColorMaxx | 1 quart, gloss | Small interior or exterior tasks |
| Rust-Oleum Advanced Dry | 1 quart, satin | Doors and trim |
| Zinsser PERMA-WHITE | 1 quart, eggshell | Interior areas where moisture resistance matters |
EVOLVE Ultra White Flat Interior Paint

This 5-gallon container is about 18.9 liters, making it the closest listed option to a 20-liter paint bucket. Its flat Ultra White formula is described as paint and primer with one-coat coverage, excellent hide, low VOC, low odor, and a washable finish.
Best for: Buyers painting a large interior area who want a near-20-liter quantity and a white, low-sheen finish. It was selected for its bulk size and stated interior-specific features. Choose this if a flat finish fits the room; avoid it if you specifically want satin or gloss. Coverage can vary with the surface, so one-coat claims should not replace checking project needs.
EVOLVE Soft Violet Satin Interior Paint

Also offered in a 5-gallon size, this paint provides roughly 18.9 liters—close to the requested 20-liter quantity. Its satin finish and Soft Violet color distinguish it from the flat white EVOLVE option. Listed features include paint-and-primer formulation, one-coat coverage, excellent hide, low VOC, low odor, and washability.
Best for: Buyers who need bulk interior paint but prefer a colored satin finish. Choose this over the Ultra White option when the listed color and sheen better suit the project. The specific Soft Violet shade may not fit every room, and the product details do not specify coverage per gallon.
Krylon ColorMaxx Gloss White Latex Paint

Krylon ColorMaxx is a 1-quart acrylic latex paint in gloss white, labeled for interior and exterior use. The supplied product information also states that it is made in the United States. Its small package makes it a practical size for limited painting tasks rather than a full-room project.
Best for: Buyers needing a small quantity of gloss white paint for a touch-up or compact project. It was selected as a latex option, but it is not close to 20 liters. Avoid this if you need enough paint for multiple large walls or want a flat or satin finish.
Rust-Oleum Advanced Dry Door And Trim Paint

This quart-size, pre-mixed satin white paint is formulated for doors and trim. Its water-based formula is described as lower odor and resistant to fading. The listed product information says it is suitable for interior or exterior metal, wood, and fiberglass, and dries to the touch in 45 minutes.
Best for: Buyers focused on refreshing doors or trim rather than coating broad wall areas. It was selected because it offers a specific finish and surface use that general wall paint may not address. Its quart size is a clear limitation for anyone seeking a near-20-liter amount.
Zinsser PERMA-WHITE Eggshell Interior Paint

Zinsser PERMA-WHITE is a quart-size eggshell white interior paint. Its listed features include a self-priming formula that requires no sanding, resistance to dirt and moisture on the paint film, and a mold- and mildew-proof film with a stated five-year guarantee.
Best for: Buyers choosing paint for an interior area where moisture resistance is a priority. Its eggshell sheen offers an alternative to the flat and satin bulk options. This is a specialty quart, not a 20-liter solution; it also should not be treated as a remedy for an existing moisture problem.
Buying Guide: Choosing Interior Paint Near 20 Liters
Is a 5-gallon bucket the same as 20 liters?
No. A U.S. 5-gallon container holds about 18.9 liters, so it is close to—but slightly smaller than—20 liters. The two EVOLVE products are the only listed options in a bulk size near that target. Check the container volume before ordering if your project requires a precise amount.
Which finish should you choose?
Flat finishes have little sheen, while satin has a more noticeable soft luster, and gloss is more reflective. These listings offer flat and satin in bulk, plus gloss in a quart. Match finish and color to the room and surface; the products here do not provide a like-for-like comparison in the same color and size.
How much paint should you buy?
Estimate the area to be painted and consult the product label for coverage and application instructions. Wall condition, color changes, and the number of coats can affect how much paint a project needs. Do not assume a one-coat claim guarantees full coverage in every situation.
When does a quart make more sense?
Choose a quart when you have a small repair or a focused job such as doors and trim. Quart products are easier to match to limited tasks, but they are not suitable substitutes for a bulk bucket when painting several rooms.
