IMPORTANT: SELECTING PAINT
This is a very versatile Spray Station that can be used with several different spray mediums in-
cluding varnishes, wood preservatives, enamels, oil and water-based paints and automotive paints.
However some materials cannot be sprayed so please check the recommendation of the
manufacturer before buying the paint. If a material refers to brush application only then it usually
cannot be sprayed. THIS UNIT CANNOT BE USED FOR TEXTURED PAINTS. USE OF THESE
MATERIALS WILL CAUSE PREMATURE WEAR, WHICH WILL VOID YOUR WARRANTY.
TO OBTAIN THE BEST RESULTS FROM YOUR SPRAY KIT, PLEASE READ THE
INSTRUCTIONS CAREFULLY BEFORE USE.
PREPARATION
Preparation of the surface and thinning of the paint are the two most important areas with which to
be concerned to obtain the best results from your Spray Station. Ensure all surfaces are free from
dust, dirt, rust and grease. If necessary rub down with sandpaper, or similar.
Masking of areas is important to ensure you do not spray those areas you wish to remain untouched.
Your Spray Station 2900 comes with a 3.0mm (0.12") Fluid Tip and a 3.0mm (0.12") Fluid Needle fit-
ted (for thicker viscosity materials and coarser finish). We recommend that you attach the 1.5mm
(0.06") Fluid Tip and Needle, included in pack for thin viscosity material and finer finish.
THINNING
Your Spray Station is supplied with a Viscosity Cup. Viscosity is a technical term used to indicate if a
product is very thin or very thick. If thin, the viscosity is said to be low, while if very thick the
viscosity is said to be high. Viscosity is measured in seconds. In order to spray some materials they
need to be "thinned" (diluted). Thinning is very important when spraying. Most paints are supplied
ready for brush application and may need to be thinned (diluted) for spraying
manufacturer's guide for thinning in conjunction with a spray gun. If in doubt please contact the
manufacturers of the paint. The viscosity cup will help you determine the correct thickness of the
paint. Paint is "thinned" by adding the substance upon which the paint is based. If it is water-based
paint then water is added; if oil based then mineral spirit or manufacturer's recommended thinnner.
As some paints, wood preservatives and other sprayable materials contain particles that have differ-
ing qualities, please ensure that when filling the paint container of the spray gun that the paint is fil-
tered through either a funnel with a filter on it or through hosiery. This will ensure that no large particles
enter the paint container, so preventing blockages and providing you with trouble-free spraying. En-
sure that a face mask, gloves and goggles are worn at all times when spraying.

If paint requires thinning, start with 10% dilution. To do this, fill a paint mixing
container with one quart of paint leaving room to add the required thinner.
Using the viscosity cup, block the hole at the bottom with your finger and fill with
the required thinner (this represents approx 10% of a quart). Pour into your
paint and stir well and re-test your viscosity. If further thinning is required repeat
by adding ½ of a viscosity cup (approx 5%) until desired viscosity is achieved.
If mixing larger batches of paint, for instance a gallon then add four viscosity
cups of appropriate thinner which is approximately 10% of a gallon. If further thinning is required
repeat by adding two viscosity cups (approx 5% of a gallon) until desired viscosity is achieved.
