6) Spray 2 coats in an instant!
One of the key advantages of the HVLP system is that you can spray 2 coats, one on top of the other (wet on wet), provided
you avoid any brush marks.
7) Innovative ability to apply slurry to basement or garage breeze-blocks.
This is one of the most spectacular uses of the HVLP spray station, which for all those users who want to cover bare breeze-blocks in a garage or
basement, or even ceilings, is a good enough reason alone for purchasing this system.
Breeze-blocks are the source of a lot of dust in a basement and painting them white with a roller would require a lot of patience and above all several
coats, which would be quite costly given that the breeze-blocks would ‘soak up’ quite a lot of paint at X euros a litre…
This problem can now be tackled at less expense by spraying white slurry with a spray gun (no, your eyes are not deceiving you!) and a single coat of
paint on top.
Slurry is a mixture of white cement and water, which must be measured out in equal quantities. Slurry ‘stops’ dust forming on breeze-blocks and even
at the drying stage gives a clean, white and more even appearance than paint. As a result, a coat of acrylic or glyptal paint is no longer needed. (One
coat of paint will suffice over the slurry)
How do I go about spraying slurry onto breeze-blocks?
a) Thin the cement with about an equal amount of water and use the 2.5 mm fluid tip-needle assembly.
b) Shake the gun at frequent intervals to stop the cement resting on the bottom of the container; spraying will otherwise be impossible. The mixture
must be consistent at all times.
c) Put 2 marbles in the container to help the mixture stay consistent.
Drying time: users should bear in mind that cement always takes a very long time to dry, even with a supply of air from the motor. The cement should
be left for 3 days before painting over it.

10) CLEANING
• Just like a paint brush, a spray gun needs to be thoroughly cleaned once the work is complete. If the gun is only superficially or partly
cleaned and the paint inside dries, the gun will soon be inoperable. This of course is not covered by the guarantee.
• For those users who follow a few simple rules, cleaning a spray gun will not take much longer than cleaning a paint brush.
• When applying water-based products, the gun should be cleaned using water.
• When applying solvent-based products, the gun should be cleaned using a solvent.
• Simply empty the gun container, remove any grease using a cloth, add a little water or solvent as appropriate, reattach the container to the
gun and then spray the contents onto some newspaper to clear out everything inside.
• The solvent (or water) passing through the inside of the tubes dissolves any of the remaining product and carries it out of the gun.
Removing the fluid tip-needle assembly (for cleaning or switching to a smaller/larger diameter). Your HV4900 comes with 2 fluid tip-needle assemblies:
a 2.5 mm assembly for thick products and a 1.5 mm assembly for runny products.
• Unscrew the adjustment ring (1).
• Remove the air cap (2), the fluid adjustment screw (8) and the spring (7).
• Pull the needle out (6). Press the trigger to help remove the needle.
• Remove the fluid tip (4) using an open-end spanner, the air flow plate (3) and the fluid tip seal (5).
• Remove the gland nut (9) and the gland seal (10). (Not required if changing from one size of needle to another).
• Place all the parts into a container and clean them using a brush (a tooth brush is ideal) and water or solvent, as necessary.
• Clean inside the gun once you have removed, cleaned and dried the container seal (12).
• Thoroughly dry the parts.
• Wipe the needle, apply a small drop of oil to the tip and then reassemble all the parts in reverse order.
Important: each needle is manufactured to fit the size of the corresponding fluid tip. Do not try to fit a 1.5 mm needle to a 2.5 mm fluid tip.
• NEVER DISPOSE OF PAINTS OR SOLVENTS DOWN THE DRAIN. ALWAYS USE YOUR LOCAL WASTE COLLECTION SITE.
• The motor unit itself does not require any specific maintenance apart from checking that the filter is not clogged up (the filter can be removed
and washed). The filter can be found in a sort of cassette at the front of the motor unit.
