Learn how to properly apply a primer surfacer.
Prescription for Applying Primer Surfacer
Spraying Primer Surfacer is not a difficult procedure if you follow these
three simple rules:
Rule #1: Always follow the paint manufacturer's recommended mixing
ratios. ALWAYS MEASURE - Never Guess!
Rule #2: Use spray equipment that is specifically designed and
engineered for spraying Primer Surfacer. 1.8 mm Gravity Feed fluid needle and
nozzle is a great choice.
Rule #3: Use low air pressures (see below for all the reasons for this
rule). Sharpe's 1.8 mm Gravity Feed fluid needle and nozzle is designed to spray
a full wet coat at low air pressures.
Adequate atomization with less air pressure allows greater transfer
efficiency resulting in many savings benefits, which include:
- Fewer coats to achieve desired film build = Less spray time
- Less overspray = Saves on cleanup time
- Self-leveling effect = Less texture to sand
- Improved adhesion = Reduced chance of peeling
- Better solvent escape = Faster through dry
- Faster cure time = Reduced sandpaper clog
- Easier sanding = Save on sanding time
- Better color hold out = Fewer comebacks
If you'll follow these three simple rules, you'll ALWAYS do a better job when
spraying Primer Surfacers.
