Most interior/exterior latex (medium body) 100–150 Mesh Balance of flow and filtration
Heavier coatings / primers 60–100 Mesh Helps minimize clogging with thicker materials

Care & Maintenance Tips

  • Inspect and clean the screen at each material change or after long spray sessions.
  • If you notice pressure fluctuations or poor pattern, check the strainer first.
  • Replace worn or damaged screens to prevent pump wear and hose clogs.
  • Match mesh size to the coating to avoid unnecessary pressure drop.

Frequently Asked Questions

The Graco 238450 Q Strainer 200 Mesh is the short style manifold screen. Confirm your sprayer uses the short screen before purchase.

200 mesh excels with thinner materials like stains, varnishes, polyurethane, and many solvent-based paints where a smooth, fine finish is desired.

Frequency depends on materials and usage. Inspect and clean regularly; replace if the mesh is damaged, deformed, or persistently clogged after cleaning.

It may, if your unit uses the same short manifold screen housing. Check your model’s parts manual or contact support with your exact model number for confirmation.

Consider a coarser mesh (e.g., 100 or 60) to reduce restriction and clogging with heavy materials. You can keep 200 mesh on hand for fine-finish work.
