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
thinner is added. If the paint requires thinning, start with a 10% dilution of the paint. To do this,
partially fill a container with one quart of paint. The viscosity cup supplied with the unit holds
1/10 of a quart. Block the hole in the viscosity cup with your finger and fill up with the required
thinner. Add the thinner to the paint and stir, and re-measure the viscosity. If the paint requires
additional thinning, repeat this step by adding 5% (5% will be equal to half a viscosity cup) with
the required thinner until desired viscosity is achieved.
If mixing larger batches of paint, for instance a gallon, then add four viscosity cups of appropri-
ate thinner, which is approximately 10% of a gallon. If further thinning is required, repeat by
adding two viscosity cups (approximately 5% of a gallon) until desired viscosity is achieved.
Always follow the manufacturer’s guide for thinning in conjunction with a spray gun. If in doubt,
please contact the paint manufacturer.
THINNING
• With any job, you should always ensure that you have prepared your surface to get the best fin-
ish. You must ensure all surfaces are free from dust, dirt, rust and grease. Lightly pressure wash
decks or exterior surfaces and ensure they are dry before painting.
• With pre-coated or pre-painted surfaces, lightly rub down with sandpaper to ensure a good bond
for the paint. With bare wood surfaces, wipe with a wet rag to ensure the surface is free of dust.
• Because some paints, lacquers, stains and other sprayable materials contain particles that are
not fully dissolved, we recommend that you strain your material through either a funnel with a
built-in filter, a paint strainer or through hosiery when filling the paint container. This will ensure
that no large particles enter the paint container, preventing blockages and providing you with
trouble-free spraying.
• Even though the Paint Zoom
®
Platinum system has very little over-spray, it is recommended that
you mask the edges and other areas and use a drop cloth to ensure that you protect those areas
you wish to remain untouched.
