FloodPenetrol 1-Qt. Clear Paint Additive

I was a bit hesitant to buying this product because in the initial picture of product on Amazon showed a gallon container but as you scrolled down the page it only showed a quart size unless you bought two gallons. That was a bit confusing, but in reviews a couple said they received the gallon container so I ordered it to see what would arrive. Happily I did get the gallon container. This is the best buy I have come across for this product. I had been paying over $10 for a quart, and those who di sell the gallon containers were asking any where from $27.00 -$57.00 , so this is much more economical.Product was delivered much quicker than I expected. The container was wrapped in plastic to keep leaks from getting in the box I had to clean the outside of container and approx. A third of liquid had leaked out because of a bad seal under the cap, but the container was easily cleaned under hot water, and having it wrapped in plastic helped contain the leakage, so I appreciated that. The cap just needs tightened down before packaging.Other than this small inconvenience I will definitely buy this product again as long as it's available.

This stuff works!The consistency is a lot like the paint itself, it’s not goopy and it’s very easy to work with!! I originally painted my doors and there were so many streaks in them so I added this for my second and third coat and WOW it actually works! Very effective at hiding the streaks in paint and giving a smooth even layer!

Great to mix with paint for a variety of projects. Gives a fun result.

The product is a good product. Liquids should be shipped in a box in the upright position to avoid spillage. A previous order the itemLeaked out. There is barely in packaging to cushion the liquid as you can see.

Very experienced DIY'er here. Been painting and refinishing various things for a lot of years. Can't believe it took me this long to discover this stuff.I'm working on a big built-in cabinet project. All scratch built. Started painting some of it with sprayer because I didn't want brush or roller marks. But what a nuisance that sprayer is. Wastes paint, takes way too long to set up, gotta put up plastic everywhere, takes too much space to do the spraying. And the CLEANUP -- yuck -- takes forever!I've got a lot of painting left to do on these cabinets. About twelve feet wide by nine feet high. Need to paint the cabinet interiors, face frames, shelves, and 20 doors.So I started Googling to see if I could find a way to paint by hand without leaving brush or roller marks. I found mention of Floetrol on a forum somewhere. Dug further. Bought some. Figured I'd try it on a few of the adjustable shelves to see if I could avoid hauling out the sprayer and all that plastic sheeting for the rest of the project.Just tried it. Shelves were already painted with primer and sanded. Added eight oz of Floetrol to a little less than a gallon of Sherwin Williams Emerald Interior Acrylic Latex Paint (semigloss). Definitely need to make sure you mix up the Floetrol itself -- very gloppy. Then when I added to the paint, I mixed the heck out of it with the paint mixer drill attachment. Used Ace best quality small (4" x 3/8" nap) white woven paint roller to spread the paint. I was pretty generous with the amount I applied.Great news: looks like it was sprayed. No trace of a roller mark. Nice, smooth, uniform coverage.No need to do another coat either. I do think the resulting finish is a little less glossy than it would have been without the Floetrol, but definitely worth it.With so much more painting to do on this project, I'm very glad I found Floetrol. Saved from the sprayer!

Have been using this stuff to treat metal and prevent rust for as long as I can remember. My dad showed me this back in the 80s, and I always keep a can in the garage. Works great for maintaining car/truck frames and keeping rust at bay. I typically wire brush the rusty area, apply a coat of Penetrol, let it dry overnight...... Then hit it with a bit of flat black spray paint then next day. Those small single use brushes from Harbor Freight work great to apply this stuff. I have never actually used it to thin paint, so I can't speak to that application. I am glad they still make it.

I've used this product for years and wouldn't be without it. I use it with Latex paint when painting faux finishes, like a wood grain or marble look, etc, when I paint furniture or when I paint walls with a paint that is hard to spread. I use it with acrylic paint for art painting and wall murals. It extends the open time (prolongs drying time) and makes your paint flow and apply SO smoothly, it prevents brush and roller marks and allows latex paint to self level like an oil base. It does not change the quality, color or opacity of the paint. You can either apply it directly onto the surface you are painting or you can mix it into the paint. It actually extends paint so it goes further. After using it so many years, I don't follow the mixing directions. I have a good feel for how much to use depending on what I'm working on and what I'm looking for it to do. The more you put into your paint, the slower the paint will dry and longer you'll have to work with it. It is white in color, like Elmer's glue, but it dries clear. As long as the cover is sealed tightly, it will be as good as new even after sitting on the shelf for a long time. I've had opened (and well sealed) bottles sit for several years and it's never gotten thick or lumpy, it never changes. I don't know what the deal is with the reviewers who have problems with it being lumpy, chunky or stringy. I never have. Just be sure to shake well before every use. When it sits for a long time, it turns clear but returns to its normal white color when you shake it up....and shake it well! This is a great product, and I recommend it for anyone doing any project using water based paint.
