Paint buckets hold more paint than paint cans and have a wider opening, making them a good choice for large paint jobs with a paint roller. More efficient and easier to use than paint trays, buckets help eliminate mess and can store leftover paint for long periods of time with their lids. Paint pails are used for mixing and measuring paints and coatings. Pails fit inside buckets to help eliminate mess. Paint cups measure and hold paint for small touch-up jobs. Cups snap shut to reduce mess and preserve paint. Some cups can attach to paint sprayers for mixing color and fluid handling.
