Paint thinners and Solvents

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.

There are basically three types of

paint: evaporative, chemical and

coagulating.
Evaporative paints cure when the

solvent evaporates. These are quick

drying paints, including lacquer and

shellac.
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.
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.
While the paint is wet, before it has

dried, you can thin or clean away the

paint using a thinner.
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.
Cleaning the paint before it dries,

using a thinner, is much easier than

cleaning the paint after it dries using

a solvent.
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

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.
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.
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.
