Nozzle for Skim Coat GRACO HDA541 0.019 inch orifice size

Nozzle for Skim Coat GRACO HDA541 0.019 inch orifice size is a replacement spray tip designed for skim coat application with compatible GRACO spray equipment. It provides a controlled material flow and a consistent spray pattern intended for thin to medium viscosity joint compounds and primers, enabling uniform skim coats on walls and ceilings. The nozzle’s 0.019 inch orifice aids in precise atomization and even coverage when applying finishing compounds where accuracy and consistency are required.

Advantages

The nozzle delivers stable output and a reproducible spray fan that helps reduce rework and uneven finishes. Its configuration is suited to maintain a balanced air-to-material ratio for improved control during skim coat operations. As a direct replacement part for compatible GRACO systems, it integrates without modification and supports efficient material transfer and reduced clogging when used with recommended compounds. The small orifice size offers fine atomization for smooth surface finishes.

Suitable for

• Applying skim coats of joint compound on interior walls and ceilings
• Spraying primers and sealers with thin to medium viscosity
• Finishing and leveling work in drywall and plastering projects
• Situations requiring a narrow, precise spray pattern and controlled output

Key specifications

• Orifice size: 0.019 inch (approx. 0.48 mm)
• Intended material viscosity: thin to medium (joint compounds, primers)
• Compatibility: designed for use with compatible GRACO spray equipment
• Spray pattern: narrow, controlled fan for skim coat application
• Function: replacement spray nozzle for finishing applications

How to use

Install the replacement nozzle onto the spray gun following the equipment manufacturer’s instructions and ensure all connections are secure before pressurizing the system. Select an appropriate material viscosity and pressure setting for skim coat work; test the spray pattern on a scrap surface and adjust pressure or material consistency as needed to achieve an even fan and atomization. Maintain steady, overlapping passes while keeping the nozzle at the recommended distance from the surface to ensure uniform coverage.

Usage recommendations

Flush the system after use with a compatible cleaner to prevent buildup and clogging. Inspect the nozzle regularly for wear or damage and replace when the spray pattern becomes irregular. Use recommended safety equipment and follow the spray equipment manufacturer’s guidelines for optimal results and longevity of the nozzle.
