Questions & Answers about Interlux Brushing Liquid 333:
2015-07-09NICK P asked: live in south florida , painting a 20'flats Boat looking at the interlux topside paint ( steel grey). Do I need to purchase the 333 to thin out the paint ? if so how much paint & 333 should I purchase and what ratio do I thin.
Thank you for all the help
2015-07-09ROBERT LATOURELLE: I used the brushing thinner to mix with Interlux filler stain not for paint thinning. Paint should only be thinned enough to be easily brushable and depending on the paint may not need any thinning. A 1 quart can of thinner should be enough for your job.
2015-07-09DAVID DAYAN: You'll have to move extremely fast and make no mistakes, but it's possible. I wouldn't recommend it though. I thinned mine about 1/3 while painting 30ft sailboat topsides in summer of the FL keys and could barely keep up.
2015-02-23A shopper asked: how much area does a qt cover?
2015-02-23Chuck Ford: I only used this product to mix and dilute Interlux mahogany stain. I stained an entire 20' Chris Craft runabout inside and out. I still have 2/3's of the container left. I also have used some of it as a solvent. I hope this helps.
2015-02-23JOHN MARTIN: I use this to apply Interlux Brightside paint. I use the brushing liquid at a ratio of 10%, so a little goes a really long way. I painted my entire 16 ft Power Cat (with an 8' beam) with less than a quart. I recommend reading the label on the intended paint for coverage estimates and thinning instructions. Also, I use rollers and brushes to paint, the instructions are different if you are going to spray.
2015-02-02A shopper asked: is interlux brushing liquid 333 a thinner?
2015-02-02JOHN NOTCH: Yes, but the main purpose is to allow the paint to flow and level out, thus eliminating brush marks.
2015-02-02MARSHALL YOUNG: The short answer is yes. It works great for cutting Inerlux's Brightside paint for applying via roll and tip method. It's also very expensive and I've found in most of my uses that normal, everyday, run of the mill, mineral spirits from any hardware store works just as well although I continue to use 333 in the most conspicuous locations. Chemically, 333 is kerosene with some naptha added so it's vapors are not much nastier to breath than any other solvent. It may give you a little more time than mineral spirits to work to your last wet edge when applying your next section of paint. Hope this helps - Good luck.
2015-02-23JOHN MARTIN: Yes it is a thinner. I use it with Brightsides paint.
2013-07-30A shopper asked: Can this be used to clean brushes which have applied brightside paint?
2013-07-30RON YATCH: Yes, 333 can be used to clean your brush after using Briteside; but mineral spirits is less expensive and just as effective. Don't re-use the same brush for varnish though. Re-use for paint is fine.
2013-07-31HOWARD SPRUIT: I assume you can clean brushes with the stuff.
I bought it to use as the label suggests.
I use less expensive solvents for general cleanup.
2013-06-14A shopper asked: What do I use to stop the Brightside White from yellowing inside?
2013-06-14WILLIAM MICHNE: If the paint appears yellow inside the can when you open it, it's most likely to be due to separation of the solvent from the pigment. This is normal. Be sure to have the product well stirred before use, and stir occasionally during use. I have use Brightside White that was a couple of years old. I stirred it well and the final result was excellent. As for brushing liquid 333, I only use that when applying varnish. I thin the varnish for the first coat or two on bare wood. I also use it when varnishing on particularly warm days. It helps the varnish flow out smoothly instead of being very thick. I hope this helps.
2013-06-14CHARLES SMITH: You can add a Very small amount of blue to the white. However I painted my first boat inside with bright side and perfection out side and it never yellowed
2012-07-03JOE PACENTI asked: can I use solvent333 to thin 2 part epoxy primer?
2012-07-03HOWARD SPRUIT: On page 14 of the Interlux "boat painting Guide" it says to use
2333N thiner for brush, or 2316N for spray!
I assume this guide is available from James town.
I know I got my copy from WESY MARINE.
On the front cover it says "For comprehensive product and maintenance advice visit
2012-06-02JOY K asked: do I clean my badger brush with this product??
2012-06-05TONY THATCHER: You probably could, but it would be expensive. I use Mineral Spirits. I keep three large solvent resistant paint buckets for cleaning. One with my "dirty" Spirits for the initial cleaning with about a quart of spirits in it. This gets pretty mucky after a cleaning. Thoroughly clean the brush in this first bucket, use a brush spinner to get rid of the excess, do it again, and again. Then go to the "Clean Spirits" bucket that has about half a quart of spirits in it. Clean, spin, clean, spin, clean spin. There should be essentially no discoloring in the clean bucket. Let the dirty spirits sit for a day. All the varnish will settle to the bottom of the bucket. Carefully pour off the relatively clean spirits off the top into the empty bucket you have. Dispose of the scum in the bottom of the first and you are ready to go again.
2012-06-05BRUCE COLLEMER: I've only used this for help in applying product and it work very good. What material are you trying to get out of the badger brush?
2012-06-05GARY SOWARD: I clean badger brushes with the reducer recommended for the product that I am using.I then wash with warm soapy water, shape the bristles and let dry.
2012-06-05MICHAEL WARREN: You can but it's an expensive way to go. Paint thinner will work for 1/4 the price.
2012-06-11THOMAS BERGER: I have used this product to thin paint for a better application. I also used it to clean brushes however, I also used product #216 which is more of a thinner and cleaner. Hope this helps.
2012-03-21A shopper asked: do i use this after applying varnish ?
2012-03-23HOWARD SPRUIT: NO
2012-03-23MATT MAHONEY: Use it to thin varnish
2012-03-23WILLIAM MICHNE: No. It has two uses. One is to wipe down bare wood just before your first coat of varnish. The second is to add to the varnish for thinning (the first two coats). You can add a small amount to the varnish for later coats, especially if you are in a hot climate, as it allows the varnish to flow smoothly and extends the drying time on hot days. I live in North Carolina and it can get pretty hot here. Note, however, that when the humidity comes up, I forget about applying varnish and go do something else where there is air conditioning.
2012-03-24Gene Quenneville: I used it more or less as a varnish after I sanded all the old finish off the wood.
2012-03-25KERRY BRANT: 333 is a great thinner for brushing brush/roller use on one part polyurethane paint. Not sure your purpose in using it after varnish, but I've used brushes dipped in it to smooth brush-lines in recently applied polyurethane paint.
2012-03-26JOSEPH WHARTON: I use the 333 as a thinner for Brightsides one part LPU paint, which is a bit thick to lay down well when brushed right from the quart can. Works fine. I estimate I thin at 5% maximum.
Always thin after pouring some from the can, that way, if the cup is too thin, you can pour the small cup full back into the can and start over, more conservatively adding thinner. I clean brushes in cheap thinner from Home Depot.
2012-03-12JOHN LABINE asked: Is it generally recommended to thin Brightsides w/ Brushing Liquid 333? If so, what's the ratio and does the ration change from the first to last coat? I'll be painting a wooden kayak.
2012-03-12JOEL HORNE: My experience is to thin it very little , about 10%. You get a smoother surface and your tipping isn't rushed so. If you thin it too much it will sag.
2012-03-12John LaBine: Much appreciated, Joel. Thank you. J
2012-03-13THOMAS BERGER: I actually used Brightsides full strength. I painted a wooden lap strake boat.
2012-03-13John LaBine: Thank you very much, Thomas! J
2012-02-22A shopper asked: how much do you mix, say with a quart of pre kote or brightside? so i know how much to buy
2012-02-23SAMUEL M ALLEN: In my experience you would only use a small amount, 1 tablespoon or less, per quart of paint.
2012-02-24ANTHONY MERLIS: Sorry, can't help. I use it only as a surface prep for prekote, not as a thinner or enhancer.
2012-03-25KERRY BRANT: I use about a 1/2 cup per quart of brightsides and prekote when using it as a thinner for rolling and spraying. I've used special thinner 216 for the same purpose, but I find it is the same with rolling and 333 seems superior when I was using it to spray with my HVLP spray gun.
At the hint of a professional varnisher in St. Lucia, added it to Epifanes Clear varnish to do brightwork in the tropical sun. Really makes a difference in how easy the varnish flows on, and creates a mirror smooth finish. The only drawback is that the final thickness is less than before so more coats are required.
Bottom Line Yes, I would recommend this to a friend
