9) HELPFUL HINTS

1) Using the fluid adjustment screw (8). Fig.1

This screw stops the trigger from being pulled back. The more you tighten the screw, the less far back the trigger can be pulled, which means that less

of the product is released. The reverse applies if you loosen the screw. In other words, the screw allows you to apply a consistent amount of pressure

on the trigger.

For a very small application, on a stencil for example, tighten the screw as much as possible to be sure of obtaining an even, mini spray. If on the other

hand you’re about to take on one of the outer walls of your chalet, loosen the screw to obtain a larger spray, as you will need a high output.

The amount of product you spray on the work surface depends on 2 factors:

a) The pressure applied to the trigger (the more you pull, the more product is released).

b) The speed at which you move the spray gun in front of your work surface.

While users will find it relatively easy to move their arms in a steady manner, they should nonetheless use the fluid adjustment screw (at least at the

beginning) to alter how far the trigger can be pulled back so that a consistent amount of product is sprayed.

With a little practice and common sense, users will be able to apply the paint evenly, which is difficult to achieve with a roller. Users can soon save up

to 20% or 30% of the product or paint they are spraying!

It should be noted that is it not essential for users who become familiar with operating the spray station to use the adjustment screw if they are able to

apply the correct amount of pressure to the trigger.

2) Only the forearm should move, not the wrist (fig.4)

3) It is better to underspray than overspray (you can always spray over what you have done).

In addition, you should also avoid spraying over a surface without moving the spray gun so that the product does not run.

The main problem for novice users is how to avoid overspraying, as this can cause products to run.

4) Floors and ceilings

The HVLP spray gun can be used at an angle, even at a 90° angle, when applying a product to a floor or ceiling, provided that a few common-sense

rules are observed. No unsightly touch-up marks will be left if you use a HVLP spray gun to paint a ceiling.

In particular, ensure that the motor is switched on before the spray gun is held at an angle so that none of the product runs down into the air hose.

(The air produced by the motor will stop this from happening)

a) Floors

Make sure that the angled feed tube in the container points towards the front of the spray gun, i.e., in a position consistent with the angle at which the

spray gun needs to be held to the floor.

b) Ceilings

When the spray gun is aimed at the ceiling, the feed tube should be pointing in the opposite direction towards the handle of the gun.

5) What distance should I hold my gun from the surface I want to spray?

There is no set answer to this question as the distance will depend on the viscosity of the product being sprayed as well as the desired accuracy. First,

the user should test the distance and move forwards or backwards as s/he sees fit. The product can be applied from just a few centimetres away for

small touch-ups in corners, alcoves or other types of decorative work, each time a certain level of accuracy is required. (For this kind of work, the user

should only apply light pressure to the trigger, hence the interest for novice users of tightening the fluid adjustment screw as mentioned above).

For large surfaces, the user should crisscross horizontal and vertical lines from about 15 to 20 cm away from the surface.
