Has anyone tried the Benron EZ tex spray all mist coat and backer coat sprayer. Is it worth trying it? Im a wet cast guy and have recently started GFRC and looking for an easier and quicker way to apply the backer coat rather than hand placing.

Mortar sprayers .com . Nolan Schied is the man with the sprayer. He is one of the most humble and helpful people in this industry.

I just tried the Benron for the first time last night. Well worth it. I'm looking forward to using it more.

The compressor used was way underpowered at 5 horse 20 gallon 125 psi but it still performed well. More cfm and less plasticizer would make it hang better on verticals and set up quicker between lifts.
If you mind your spraying technnique this also gives you very clean and even layering. The backside looks much neater and uniform with much less effort.

I will be ordering a new compressor with more than enough cfm. You probably do not need the 100 cfm at 100 psi to be happy but more air flow is better.

The Maxair I'm ordering could probably run two guns at once and is a great deal from Air Compressors Direct. 18.5 cfm at 100 psi, 60 gallon, 170 psi max, $1,099.99, free shipping, no tax (except Illinois).
I love mime , I just panic the hopper is gonna fall off as it doesn't sit well on my gun no matter how hard I tighten it . Don't know if it is the same wlth other guns . I also like that it runs off the smaller compressor

Mark, I have to disagree with this statement: "There is no need to spray a flat, just cast an SCC backcoat and get done in seconds." Orientation of fibers is essential, which is why you must apply thin backer coats and roll them with compaction rollers. See this article: http://www.concretecountertopinstitute.com/blog/2013/06/scc-backer-...

Really interesting in this range of cement content @ 40 %  + you all know that water is the enemy right ??

Mark, your post simply stated "you can just pour SCC", without qualifying that they need to use your products to do it, and NOT use standard liquid polymer. Assuming your products do work, I would still have to disagree with the statement as you made it. :-)

But to address your response: Standard GFRC is standard because it works, and it has been scientifically proven over decades to work, by university level research using the scientific method, not by product vendors using proof by example.

Why do the big commercial building panel producers use liquid polymers and >6% fiber loads? Because it works. And that's a massive industry that most certainly has done their research and has major incentive to save cost and time.

I'm not saying your products can't or don't work, I'm saying we need a whole lot of scientific evidence that they do. (And I believe you've been gathering some, that's great.) In the past, we've been burned by other vendors' proprietary products that simply did not stand up to their claims when tested scientifically, even though lots of people said "it worked for me".

This is one of the biggest misunderstandings I've seen in the concrete countertop industry. People don't understand that you cannot *prove* anything by example. You need carefully designed experiments that test a clear hypothesis and are repeatable - the scientific method.

CCI would be happy to test the Trinic products, and we'll work with you to design our experiment. Give me a call if you'd like to discuss further.

I wont name any companies so my comment wont be unqualified, I dont use any Trinic products and i can " just pour an SCC backer" to make countertops, sinks, wall panels, etc. Not only will i not have any problems, but it will be stronger than the "standard GFRC" that "works"! It is nice to know there are companies like trinic & the one i use who want to make concrete better and who are making products that push past the "standard GFRC" that works. Just imagine how far behind we would be if not for people who wanted more from their product, im glad there are people who dont settle for what has proven to work. I would be willing to bet that the companies making products that push past standard GFRC do a lot more testing than someone trying to sell something they took no part in developing. Why would anyone want CCI to test their product, CCI has never set any standards for concrete or testing? Other than google ranking and a marketing strategy what has CCI ever developed on their own?

O snap when concrete personality collide. I am with Mark on this one. I do not use his additives but I have poured hundreds if not thousands of GFRC ,ECC, and SCC mixes and I have never used a roller and I have never sprayed a flat  piece of concrete nor will I ever. I do not need any body's products to do this with the exception of AR fibers and cement. I also have never had a call back due to strength ,compression or tension failure.

  I respect both Marks opinion and CCI opinions in these maters but at the end of the day my ass is on the line and I have more faith in the techniques I have learned threw my own blood sweat and tears over any guy in a lab with a microscope and a engineering stamp.

I guess anyone that does not have the CCI badge will have to close their doors.  If Mark is not qualified to test concrete with all his experience.  I had respect for what CCI was doing but thats gone now.  I don't know why CCI joined this forum if they know so much better.  I checked out Buddy Rhodes GFRC video and he is doing it all wrong too.  Look out guys only shops that have the CCI badge are going to make it.  I have not tried Marks additives but had good results.  I don't care what anyone says but I say Mark has This one by a mile.

PS- The thing I would like to know is how does CCI qualify to be the ones giving Badges setting the standard?

Ouch!

We are not making exterior wall panels that hang on buildings.  I also have a problem with people over complicating our products, always trying to sell us on what is optimal.  We don't need optimal, good is nice in this industry.
