Pick fair test areas
Use areas that see similar airflow, dust exposure, cleaning schedules, lighting, and traffic. Good options include support rooms, plant corridors, storage areas, maintenance rooms, doors, trim, and painted walls near production traffic.
Use the same paint system
Keep the paint brand, color, sheen, primer, surface prep, and application method the same. The only thing that should change is the RepelX dose.
Compare these areas
- Control area: same paint without RepelX
- Standard RepelX area: 1 oz per gallon
- Heavy-dust test area: 1.5 oz per gallon
Do not overdose
Do not exceed 1.5 oz per gallon without direct guidance. More additive does not automatically mean better dust resistance and can start to affect the finish.
What to measure
Take photos after painting, then again after normal facility exposure. Ask maintenance, cleaning, and operations staff which area looks better, cleans easier, and still looks like the intended paint finish.
