How determine alkyd or acrylic?

To determine whether a paint is alkyd or acrylic, check the label for specific terms; alkyd paints typically indicate they are oil-based, while acrylic paints are water-based. Additionally, you can perform a simple solvent test: apply a small amount of mineral spirits to a cotton swab and rub it on the paint; if it softens or dissolves, it’s likely alkyd. Conversely, if it remains unaffected, it’s likely acrylic. Lastly, the drying time can also be a clue; alkyd paints generally take longer to dry than acrylics.
