Question

I would like to know what solvent is used for what painting job. There are a few solvents on the market e.g. Turpentine, thinner, methylated spirit, white spirit, kerosine, etc. that I am afraid that I might use the wrong solvent for thinning. I am aware that latex paint uses water for thinning. What I am specifically interested is the solvent for lacquer, shellac, varnish. What is the difference between methylated spirit and white spirit?

Personally, I think you're reading a very old book (which should either thrown out or you should learn the conversion names), you're reading a book published in the U.K. or Europe (in which case the same advice applies), or it some sort of homework assignement.

In todays World of painting this information rarely applies, but, since this is a Do It Yourself Web Site, here is a list of the more common solvents, after which, you are on your own.


MEK "Methel Ethel Ketone"
(AKA "Synthetic Reducer" - may be combine with other solvents)
A high strength solvent.
Use:
A specialty solvent to be use only where directed and as directed.
Generally for epoxies, fiberglass resins, and specialty coatings.
Cleaning:
Use to clean painting tools after applying any type of coating.
Will soften hardened coatings and most synthetic materials including synthetic brushes.
WARNINGs:
Flammable. Read cautions on the label carefully.
Do not use a confined area without proper ventilation.
Toxic, with cumlative affects. (Death, Brain, and Nervious System disorders).
Will attack some synthetic brushes.
!! Do not use with standard spray equipment.
!! Spray applications: wear a fully self-contained positive pressure suit.

Toluol - Toluene
A high strenght solvent.
Use:
A specialty solvent. Use as directed to thin many lacquers, rust inhibitive, rubberized, marine and other specialty coatings.
!! Not for use with most oil based paints, varnishes, stains, shellac or polyurethanes.
Cleaning:
Use to clean painting tools. All coatings except shellac.
Will soften hardened coatings and most synthetic materials including synthetic brushes.
WARNINGs:
Flammable. Read cautions on the label carefully.
Do not use a confined area without proper ventilation.
!! Vapors linger at floor level. Do not use a confined area without proper ventilation as the possibly of an explosion from an ingnition source is real.
!! Nitified Toluene is the explosive "TNT".
Toluol is a octane booster for gasoline. Some Hot Roders add it to gasoline for performace reasons.
Toxic, with cumlative affects. (Death, Brain, and Nervious System disorders).
!! Do not use with standard spray equipment.
!! Spray applications: wear a fully self-contained positive pressure suit.

Xylol - Xylene
A high strenght solvent.
Use:
A specialty solvent. Use as directed to thin many lacquers, rust inhibitive, rubberized, marine and other specialty coatings.

Acetone
A high strength fast evaporating solvent.
Use:
A specialty solvent to be use only where directed and as directed.
Generally for epoxies, fiberglass resins and specialty coatings.
Cleaning:
Use to clean painting tools after applying any type of coating.
Will soften hardened coatings and most synthetic materials including synthetic brushes.

Flammable. Read cautions on the label carefully.
Do not use a confined area without proper ventilation.
Toxic. (Death, Brain, and Nervious System disorders).
!! Do not use with standard spray equipment.
!! Spray applications: wear a fully self-contained positive pressure suit.

Paint Thinner
A general purpose solvent.
Use:
Most oil based paints, varnishes, stains, polyurethanes and wiping oil finishes.
Increases flow, reduces brush drag, and extends drying time slightly.
!! Do not use with shellac, lacquers or latex paints.
Cleaning:
A mild solvent. Clean painting tools while coating is still wet.
Will not soften dry paint films well.
WARNINGs:
Flammable. Read cautions on the label carefully.
Do not use a confined area without adequaret ventilation.
Toxic. (Death, Brain, and Nervious System disorders).

Gum Turpentine
Use:
Thinning most oil based paints, varnishes, stains, polyurethanes and wiping oil finishes.
Increases flow, reduces brush drag, and does not extend drying time noticeably.
Its evaporation rate is the same as many paints.
!! Do Not use with shellac, lacquers, and latex paints.
Cleaning:
Gum Turpentine leaves a slight rosin residue.
Clean painting tools while coating is still wet.
Will not soften dry paint films well.
WARNINGs:
Flammable. Read cautions on the label carefully.
Do not use a confined area without proper ventilation.
Toxic. (Death, Brain, and Nervious System disorders).


Mineral Turpentine
(AKA Mineral Spirits)
Use:
Thinning most oil based paints, varnishes, stains, polyurethanes and wiping oil finishes.
Increases flow, reduces brush drag, extends drying time slightly.
!! Do Not use with shellac, lacquers, and latex paints.
Cleaning:

Kerosene
Use:
The purest lowest sulphur grade (1-K) may be used in place of Paint Thinner but it increases drying time.
Kerosene is mainly a fuel.
Cleaning:
Clean painting tools while coating is still wet (oil based paints, stains, varnishes or polyurethanes).
Will not soften dry paint films well.
WARNINGs:
Flammable. Read cautions on the label carefully.
Do not use a confined area without proper ventilation.
Toxic. (Death, Brain, and Nervious System disorders).
