How much thinner do I mix with lacquer?

Mixing Lacquer If you do need to add lacquer thinner, you usually fill the spray cup about three-fourths full of lacquer and then add the thinner. You shouldn’t have to thin by more than 20 percent. Mixing catalyzed lacquer requires more precision.

Applying Clearcoat/ Clear Lacquers Normally the mixing ratio will be 2 parts clear and 1 part Activator plus 2K thinners to adjust for spraying viscosity. Some Clears might have slightly different mix ratio so essential to read manufacturers instructions to obtain the best results.
