Generality

This machine can use products with a viscosity ranging from 10 to a maximum of 35 (35 DIN-s).
A paint with a much higher viscosity can be used only for water-soluble products for outdoor and indoor wall
applications. The quantity and type of paint are very important.
The main viscosity values for the most commonly used products are:
Filler 10 to 20 DIN-s
Wood dye 15 to 25 DIN-s
2-pack paint
20 to 35 DIN-s
oil paint
The product manufacturer's instructions for the type of thinner and the quantity, in percentage to be added (this
may vary from 5 to 50%).

Preparations

Preparing the Surface

To obtain good results, the objects or surface to be treated must be cleaned.

Remove any traces of rust or scaling from the old paint and, if necessary, rub it using sandpaper.
Stucco or rub with sandpaper, where necessary, to make the surface smooth.

Carefully read the instructions indicated on the paint can. Manufacturers usually suggest to apply a fixative
before painting to obtain the best results and, above all, to save paint.

Preparing the Work Piece for Painting

Shake well. Pour paint inside the paint sprayer reservoir, without filling it to the top (maximum ¾). Use a stick to
mix and stir the product.
Thin the product following the manufacturer's instructions. If necessary GRADUALLY ADD THINNER AFTER
MAKING TESTS ON A PIECE OF CARDBOARD OR WOOD.
After checking that the product has been correctly thinned, the entire work piece can now be thinned. For more
