    Thinner Extends the Drying Time of the Varnish
  

*by M***L on Reviewed in the United States on May 20, 2019*

This product does not act like a normal thinner.I followed the instructions and applied the 1st coat of Schooner Gold varnish thinned 50% with the Interlux #333 thinner.  That coat of varnish did not want to dry.  It was still sticky after 24 hours.  Interlux tech service (he called back very quickly) suggested that I lightly sand or steel wool the surface to tear open the film that had formed on the top surface of the varnish.  That worked for the flat areas but not the routed moulding on the door.  It was too thick in those crevices.  There I had to use small detailing brass and plastic brushes; a plastic scraper, and working off and on for 6 hours while the door sat in the sun during an 85°F May afternoon to get the excess removed.The Interlux #333 thinner's label states that it "is a slow drying solvent" and "extends the drying"; no joke!  I had to wait 48 hours (including 6 hours in the hot Texas sun) for the thinned varnish to dry before applying the next coat of varnish.The 2nd and 3rd coats were 100% varnish and they dried well but rough surface.  I found that the 100% Schooner Gold dried in 1/3 to 1/2 the time of the varnish thinned with #333.  The 4th coat I diluted 25% with normal mineral spirits and it gave a much smoother surface.  I did a few test pieces and settled on a 50% dilution with mineral spirits using a foam brush for the 5th and final coating.  The cheep foam brush did better than the expensive Purdy.  This is what you see in the photo.I also used the Interlux #333 to thin the Schooner Gold varnish for a Wash Coat before staining and the Interstain per the instructions.  I did not have any drying problems but on both situations the liquid was ~75% Interlux #333 thinner and the stain was wiped off after a few minutes.I am happy with the final finish.  I just wish that following the instruction with the Interlux #333 thinner did not cause me the problems that I experienced.I worked in chemical plants/refineries for 35 years and this stuff has a really bad odor.  I am glad I had a good twin canister organic vapor respirator.

    Without it your interlux brightsides will be thicker than it's supposed to be
  

*by B***G on Reviewed in the United States on October 16, 2018*

Thinning did cause my foam roller to sew bubbles all over the place, but they pop easier. 1 part polyurethane paint is spongy and weak so it's essential you follow the directions to apply insanely thin coats. This thinner makes that easy. The smell is intense.. must be good.

Need this to  dilute interlux bright side in hot temperatures.
