MLC Magnamax H2O Precat Water Borne Poly4/24
I have sprayed with waterborne finishes for over 10 years. I currently use MLC Agualente Plus products. My supplier has now started to push the MLC Magnamax H2O Precat Water Borne Poly. I have ordered some to try. Hoping it will provide a much harder surface than the Agualente plus.
Has anyone tried this product yet? It does cost more and I'd like to know what you think of it. Any suggestions on it's application. I spray with a CATech AAA.
My supplier gave me a sample quart to try and I used it yesterday. It looks good, and feels good. It is VERY thin unlike any other waterborne Iíve sprayed before. The PDS says to lay it down at I believe 4-5 wet mills, but I can tell you there is no way you could spray that thick on a vertical surface and not have run or sags.
I sprayed it through a 4 stage hvlp turbine because I just had two shelves to spray. I would like to try it through my AAA with a
Thanks Marc, I have received mine , but have not used it yet. Hope to try it today. I'll be using it in my AAA with the 409F tip.
I Finally had a chance to spray this on a job. It does lay down great. It feels great. It looks great. And It gives an immediate amber appearance.
But. It is very thin right out of the can. I found on vertical surfaces multiple very thin coats is the way to go. I think like all waterborne products it takes a lot of practice to get used to it. And Patience, Patience, and more Patience.
My MLC rep told me Magnamax H20 was put out in response to complaints that water bornes are crystal clear. It gives the Amber tint that comes with some oil based pre cats or Polyurethanes. Worked well for me.
I just finished a large job with MagnaMax H20 and learned a lot. I used both Aqualente and Sherwin Williams Kem-Acqua for the past 10 years. I love the feel and the look of it. I used to spray a first coat of de-waxed shellac to get the color, but the MagnaMax gives me that color without needing the shellac. I also like the way it scuffs; it powders up perfectly after about 20-30 minutes and doesn't clog the paper like the other products did.
As everyone else mentions, it is super thin. I was using the same 1.3 tip with my CA Technologies CPR gun, but it didn't seem to be atomizing well and a ton of material was coming out no matter what I did with the gun settings. It was getting a bit of orange peel and a lot of bubble pops and nibs. For fun, this morning, I switched to the only smaller tip I had which was 0.8; I was amazed that it even sprayed at all, but because it's so thin, it not only worked, but laid down perfectly. I had to slow down a lot to get enough material, but it worked very well.
I have contacted my rep to see what tip and settings are recommended by CA Technologies and ML Campbell. I had a horrible problem with drips on vertical surfaces with the 1.3 tip, so I'm curious what they recommend. I agree that 4-5 wet mils couldn't possibly hold on vertical surfaces, so several light coats seem to be the ticket.
I'm really happy with the coating so far and am looking forward to figuring it out. Practice, practice, practice, for sure...
I cannot turn my AAA pump fluid down any more and still get it to prime. I already use a 409F tip, which is pretty small.
I'm gonna order a 407F tip and experiment with it.
If I can get the sagging under control, I will be very happy with this product.
I have now sprayed 10 Gallons thru my Cat 14:1 AAA. The last seven with a 407F tip.
The 407F made everything much easier. I was able to control the spray in every way. I have found that several thin coats virtually stopped the sagging and runs.
what fluid pressure are you set at? and air?
Fluid pressure is 350. The air pressure I have found best at 19 to 20.
It's great to hear you had success with the smaller tip. I finally did get a 1.0 tip for my gun and it worked great. I still haven't had the opportunity to spray much vertical stuff and I'm a little worried about doing that successfully without runs, but I guess I'll just have to be careful and use multiple light coats.
I sprayed a lot of drawers, I only had to be extra careful in the corners. Light coats did it for me there.
On locations where gun/ hand control is not so restricted, runs were easily controlled with regular coats.
