Keep Polyurea & Spray Foam Equipment Ready for Production

Clean Applicator Guns, Hoses & Mixing Chambers

SprayFoam Flush 4 dissolves and displaces polyurethane foam residue quickly, helping keep spray foam guns, hoses, and mixing chambers clean and free-flowing between applications.

Reduce Downtime and Protect Your Equipment Investment

Support Consistent Spray Foam Application

Residue buildup can contribute to clogged lines, inconsistent mix ratios, and wasted passes. Regular flushing helps maintain clean equipment so your spray foam system can deliver more consistent output from job to job.

Make Routine Equipment Maintenance Easier

Equipment is a significant investment. Adding Flush 4 to your maintenance routine helps reduce buildup-related interruptions, unplanned downtime, and costly repairs.

How to Use Flush 4

Use Flush 4 at the end of each work session or when changing formulations. Flush it through the applicator gun, hoses, and mixing chambers until the solvent runs clear.
