Understanding

Paint Thinners and Solvents

1.Understand the difference between a paint “thinner” and a paint “solvent”. A thinner is used to thin the paint while it is wet. A solvent is used to dissolve the paint after it has dried.

Paint Type	Thinner	Solvent
Latex	Water	Paint Remover
Water	Water	Paint Remover
Based
Paint
Oil Varnish	Mineral	Paint Remover

	Turpentine
Lacquer	Lacquer	Lacquer Thin-
	Thinner	ner
Shellac	Alcohol	Alcohol

2.There are basically three types of paint: evaporative, chemical and coagulating.

3.Evaporative paints cure when the solvent evaporates. These are quick drying paints, including lacquer and shellac.

4.Chemical paints cure when there is a chemical reaction solidifying the paint, as the solvent evaporates. Oil- based paint and varnish are of this type. They are relatively slow drying, and may cure over months or years.

5.Coagulating paint such as latex and water based finishes are composed of bits of paint suspended in water. As the water evaporates the bits of paint adhere to each other and form

a paint film. The paint film chemically bonds together.

6.While the paint is wet, before it has dried, you can thin or clean away the paint using a thinner.

7.Once the paint has dried, in most cases the thinner can no longer be used. You must then use a solvent to remove the paint.

8.Cleaning the paint before it dries, using a thinner, is much easier than cleaning the paint after it dries using a solvent.

9.Always clean this spray gun immedi- ately after use, before the paint dries. Use the thinner approved by the manufacturer for your paint.

Painting Technique

with this HPLV Sprayer

1.Your goal in painting with this sprayer is to get good coverage of the work piece. You want an even coat with- out drips or runs and with a smooth surface.

2.To get an even coat, hold the spray gun 6 to 8 inches away from the work surface. Keep the distance of your gun from the project, as consistent as possible.

3.Start spraying slightly off the edge of the work piece, move the spray across and end slightly off the work piece. Overlap each pass across the work piece. While this method does create over-spray at the edges, it will give you an even coat without heavier or lighter layers at the edge.
