Add vial to quart of MEK to make PVC stain. Will not chip off like paint, stain is embedded in the plastic. Stain can be sprayed or rubbed on. 14 ml vial
To use the stain, add the entire vial (14 ml) to one (1) quart of MEK (methyl-ethyl-ketone). MEK will melt a plastic container; it must be metal or glass.
Apply it to the pipe with a brush or spray applicator. This should be done outdoors. The pipe does not need to be prepared; the MEK will de-gloss it. Several light applications will give better results.
