How do I troubleshoot poor adhesion or uneven thickness with spraying equipment?

Poor adhesion or uneven thickness usually points to incorrect nozzle standoff distance or angle, water ring miscalibration, or air pressure that does not match the specific mix being applied, particularly when switching between dense and lightweight insulating castables. Adjusting one variable at a time and checking against the mix manufacturer's recommended parameters typically resolves the issue faster than replacing equipment. Sparkline Group's technicians can diagnose whether the cause is equipment setup or mix-related during a site visit. Addressing this early avoids costly rework on large surface applications like kiln preheaters.
