Which roller cover material is appropriate for latex paints?

• A. Nylon
• B. Polyester
• C. Polypropylene
• D. Wool

Answer: (A)

When painting with latex, the goal is a roller cover that handles moisture well and doesn’t shed fibers. Latex paints are water-based, so you want a synthetic fiber that stays stable in water and cleans up easily. Nylon fits this well: it resists swelling, maintains its nap shape through repeated use, and gives a smooth, even finish with water-based paints. It’s durable and less prone to leaving lint in the coating, which is why it’s a reliable choice for latex finishes. By comparison, wool is natural and tends to absorb water and shed fibers, which can ruin a latex finish. Polypropylene is less common for finishing with latex and may not deliver the same balance of durability and smoothness. Polyester can work, but nylon’s combination of performance and ease of cleanup makes it the best match for latex paints.
