  • It Works. That's it, and that's all.
Style: 1 Quart
Before spraying this on a piece of plywood that I wanted to protect, I sprayed it on a big piece of corrugated cardboard. Which is what I use as kindling to start fires. And then I tried to light it with an Aim & Flame. It did not burn. I don't know how it works, and it's a tad pricey, but if you want to make something fireproof, this stuff seems to get the job done. I also mixed it with some primer on another project (which they say you can do). Made the paint thinner, which I expected. But then it started to really thicken up after awhile, like Thompson's waterproofing product. I applied it, and it went on fine, but a little grainy. I assumed from this that it has some active ingredients that really harden surfaces and paint. So I think this was a good buy. If it ever has to stop a fire, it's a great buy. ... show more

  • Seems to work, makes paint very thin & watery
Style: 1 Gallon
I bought this to mix with paint to paint my exposed basement posts, beams, and joists. I mixed a full gallon of this with a little less than a gallon of latex paint. I did a couple tests on some scrap boards first, and it didn't work when I first tried it, but I missed the part about waiting 24 hours. Tried it again the next day and board turned a little brown, but would not burn and hardly even smoked. This seems to work exactly as described and is way better than nothing. I used a small foam roller to apply this to the exposed wood in my basement, to give it a nicer finished look, while adding fire protection without having to wrap everything in a bunch of drywall. This product makes the paint super thin and watery, and it drips EVERYWHERE, so I ended up masking things off almost as much as i would have if spraying. Also, because of how thin it is, it takes many many coats to achieve a uniform opaque color. I think I did 5 coats before I couldn't see the old paint colors where some of the wood had been painted decades ago. This product also separates from paint really easily, so you have to keep mixing it throughout your project if using very much. It probably separates as much as 90% after sitting for just an hour, and after being left overnight I could probably pour the Master Flame back into the bottle, leaving the paint behind. I'm glad i found this product as it's saving me from having to wrap things in metal or drywall, and gave me justification for painting the entire basement ceiling (instead of just the areas that were previously painted blue, green, or cream. I used up the first jug and just bought another, I'll probably need a 3rd to finish the entire project, it's an 1100sf basement with 100 year old wood that sucks up the first 2 coats of paint. I took 1 star off for how thin it makes the paint and how quickly it separates. It would be nice if they had a thickening agent you could add or they could get it to bond with the paint. ... show more

  • TJI joist fire retardant
Style: 5 Gallon Pail
I use this stuff for fire code for TJI floor joist. I mix it with contractor paint and it works great in my airless sprayer. I will cause metal to rust so do not spray on metal surfaces. I usually use one bucket for a 1,800 sq ft house.

Style: 5 Gallon Pail
Though the instructions leave a bit to be desired; through a little research and trial by fire, we were able to get things moving with this stuff pretty quickly. We have currently used about 25 gallons and have not been disappointed. We use it 3 ways ---- We dip some articles, we spray wood and walls with a spray gun and compressor, and we mix it in our paint and roll it on. The best method is spraying, but if mixing in paint and using a roller, make sure to use a very thick nap roller. This stuff is the consistency of water and requires a 50/50 mix with latex paint. However, not all latex paints are created equal when it comes to this. There is one brand that we have found works the best. And another brand that doesn't work at all. The brand that doesn't work at all caused us to lose about 4 gallons of the retardant because the paint had a bad reaction to it. This is definitely the best buy for your buck when it comes to fire retardant and is the most versatile. ... show more

  • Vague Instructions

Sprayed this on the bottom of my utility closet walls in hopes to prevent any fire. Do I need to re-apply at some time intervals??

  • It does work takes half of a month to harden though
Style: 1 Quart
The media could not be loaded. You can hear the toughness of it. From soft to hard. It takes alot. Soak the hell out of it. It took almost a month to dry and harden. Turned yellow a little bit. Didn't know if it was actually going to work. I sprayed it every other day for like a week. Then let it sit. When I peeled it back on the lid. It only went through a few layers, not the entire thing. The outside is harden which is fine. The spray does work, some pieces fell or chipped off, and the inside of the furnace will need more soaking and spray, l hit and dragged my finger across it so that the toughness can be heard and seen. No video or pictures prove that it actually works. But it does, I'm using it for a furnace. ... show more

  • Fire safety
Style: 1 Gallon
I had to buy this to pass my life safety inspection We placed the master fire in all beams to ensure fire resistance. This product can be layered to increase fire rating. One coat does a 30 minute fire rating.
