Thinning
Thinning is particularly important when spraying. Most paints are supplied ready for brush
application and need to be diluted sufficiently for spraying purposes.
Follow the manufacturers guide for thinning in conjunction with a spray gun. If in doubt
please consult the manufacturer of the paint. The viscosity cup supplied will help you
determine the correct thickness of the paint. As some paints, wood preservatives and
other sprayable materials contain particles and have different qualities, please ensure that
when filling the paint pot on your spray gun, the paint is filtered through either a funnel
with a filter on it, or through nylon tights or stockings. This will ensure no large particles
enter the paint pot, therefore preventing blockages and providing you with trouble free
spraying. Ensure that a face mask, gloves, goggles and ear protectors are worn at all
times when spraying.
Floetrol
®
is an acrylic paint conditioner that you can add to the paint pot which is for
easy, trouble-free spraying. It helps thin your paint however also reduces wear and
replacement cost of parts within the spray gun. It also reduces tip clogging avoiding
freeze up in the trigger which gives you a professional finish. Floetrol
®
is available
from Bunnings Warehouse.
Determining Viscosity
Information regarding dilution or thinning is normally found on the
material tin. Use the viscosity table to determine the thickness of
the coating material.
First stir the spraying material thoroughly then to determine the
viscosity, dip the viscosity cup into the material below the rim
level and fill up. Lift the cup out of the tin and start timing as
soon as the cup is above the surface. Time how long it takes the
viscosity cup to empty (Fig. 3). Use the chart below as a guide to
determine if the material requires further thinning and thin
accordingly, within the material manufacturers recommendations.
This runout time is called DIN seconds (DIN-s). Use this table as a guide only.
