Preparation

J

• Most paints are sold ready to be used with a brush. They 

need to be thinned before applying with a spray gun. 

Follow the manufacturer’s instructions to thin it.

• Adding a thinner is recommended. Add 5 to 10% until 

reaching the right viscosity to apply the material.

• Use the viscosity measuring glass (not included) to 

determine right viscosity of the paint. Viscosity is 

determined by counting the seconds it takes for the 

material to be discharged into the measuring glass. The 

following table shows the recommended times for 

different products.

• If after thinning the product 

the dispersion capacity is too 

low, add thinner. Add slowly 

from 5 to 10 % until the 

dispersion capacity meets 

your needs.

• If the paint is too thick, the 

painted surface will be too 

rough (orange peel). If the 

paint is too liquid, there is 

risk of dripping.

Thinning the material

• Unscrew the paint gun jar.

• Align the suction pipe suitable for the job:

To spray horizontal objects set the suction pipe forward (

A

).

To spray surfaces above your head, set the suction pipe 

backwards (

B

).

• Set the jar onto a piece of newspaper.  Pour the 

prepared covering material and tighten the jar firmly into 

the paint gun.

Filling the Jar

• To make a good job, it is important to prepare the surface to be sprayed. Thin the paint or product to gain the right 

viscosity before applying.

• Always double check the surface is free of dust, dirt or grease.

• Make sure to cover with adhesive tape, some newspaper and/or plastic those areas that do not require spraying.

• Paint or product to be sprayed shall be mixed perfectly before filling the jar to prevent they settle and to make them 

lump-free.

• Before buying the product read the manufacturer recommendations.
