PAINT THINNING
Paint thinning is particularly important when spraying. Many paints are
supplied ready for brush application and need to be sufficiently diluted for
spraying purposes. Always follow the paint manufacturers instructions. If in
doubt, always consult the paint manufacturer.
A Viscosity Cup (not supplied), will assist in determining the correct thickness of
the paint.
The ideal viscosity for most paints is as follows:
1. Dip the cup into the paint and fill to the brim. Time how long it takes for the
cup to empty.
2. Thin as required until times are achieved.
3. Alternatively if a viscosity cup is not available, the following information
can be used as a rough guide.
• Water based paints (emulsions) 10-20% water.
• Oil based paints (gloss) up to 10% thinners.
• Cellulose paints up to 50 % cellulose thinners.
If in any doubt, contact the paint manufacturer.
Having mixed the paint thoroughly in a separate container, pour into the spray
gun paint container through a fine filter.
• DO NOT OVERFILL PAINT CONTAINER - never more than three
quarters full.
