Applications / Choosing the Right Paint Strainer for Your Project

January 30, 2026

When it comes to achieving a smooth, professional-quality paint finish, few tools are as underrated (and essential) as the paint strainer. Whether you’re a DIY painter or a pro contractor, incorporating paint straining into your workflow can prevent clogged spray guns, eliminate debris in your paint, and ensure a flawless final coat.

Trimaco understands how important straining paint is for any scale project. We’ll walk you through why painters use strainers and how to choose the right paint strainer from Trimaco’s lineup of paint strainer bags, cone strainers, and the E-Z Strainer.

Why use a Paint Strainer?

Even when paint looks smooth in the can, unwanted particles can settle or form during storage, things like dried paint flecks, dust, and impurities. A painting strainer acts as a final filter before the paint touches your brush, roller, or sprayer.

Using a paint strainer helps you:

• Prevent equipment clogs: Especially important for spray guns.
• Achieve a smoother finish: Clean, strained paint applies more evenly.
• Extend paint life: Removing contaminants improves the consistency and longevity of your paint.

How to Choose a Paint Strainer

Selecting the best paint strainer depends on your coating type, tools, and workflow. Trimaco offers several reliable options designed for different needs. Here’s a breakdown to help you decide:

Cone Strainers

Trimaco’s cone paint strainers are ideal for small batches of paint and spray equipment prep. These disposable, easy‑to‑use funnels fit securely inside most paint cups or small buckets and come in both medium and fine mesh options for filtering latex, stains, and solvent‑based coatings. Their shape and size make them perfect for quick jobs where precision matters. If you want fast, reliable filtration without setup or cleanup, cone strainers are a go‑to choice.

Bag Strainers

Paint strainer bags are designed to filter larger quantities of paint quickly. The elastic‑top bags stretch over 1‑gallon or 5‑gallon buckets, making them stable and mess‑free during high‑volume use. Available in multiple mesh sizes, they’re great for thicker materials and repeated straining throughout a project. Choose paint strainer bags when you need speed, consistency, and the ability to handle more paint at once – especially on professional or extended jobs.

E-Z Strainer

Trimaco’s E‑Z Strainer is a durable, elastic top strainer designed for projects that actively use a paint sprayer while the paint is still being strained. Its small slide‑access hole allows a sprayer to pull clean, strained paint directly from the bucket, even as the strainer continues filtering more paint above it. This makes it perfect for uninterrupted workflow and continuous spraying. Offered only in a 5‑gallon size and 600‑micron mesh.
