MLC Agualente + & Surf Prep Pads9/14
I have been using MLC Agualente (Clear and Pigment) and Valspar Zenith for years. About 2 years ago I tried the Surf Prep and have used it ever since. It worked great with both MLC & Valspar products.
I just started a new job with the new Agualente Plus (Pigmented). The primer was fine. It powered perfectly and the pads had no build up as usual. When I sanded the Agualente Plus between coats, It started clogging almost immediately with very little powder. At first they were small nail head sized blotches that took a great deal of compressed air to remove and then larger spots. It was so bad I had to go back to 320 sand paper by hand.
I always let the Waterborne dry at least one hour before I sand. Tried it on more doors after I let dry longer and the last one I let dry over night. No change.
I contacted the Regional MLC rep that I have dealt with for years. He said he was not surprised, since they have had other issues concerning the new formula. (Dry Times, Stacking Time, Wraping Time etc The primer has not changed.
He said the new formula appears to affect how long it needs to dry and suggested using very thin coats and a lot of moving air over the items after it skins over.
Curious, if anyone else has had other issues with the Agualente Plus. So far I'm not very impressed.
The Surp Prep has really spoiled me and I definitely do not want to revert back to sanding with paper.
I used Mlc waterborne a few times
We have had the same problem with the new Agualente. Its horrile. Drytimes are abysnal. The last gallon we had went into the trash and no more. The old formula dried fine and scuffed fine. This stuff is horrible. God forbid its 95 and humid. Your dead.
I notice it being soft and gummy, but not unsandable. I have a problem with it cratering terribly out of my airless after the first coat. I thought I had it fixed with a diffeerent tip, but the problem is back. Its totally bumming me out
Well, I have been really frustrated with the Plus. It is like starting over. I have been using waterborne for about 10 years and had the old Agualente working pretty good.
Since I made my post, I have been experimenting, trying to get a handle on it. I have wasted a lot of valuable time. Not much luck. One more thing I found that helps, is after sanding between coats, place it back under the fans for a while. Its almost like sanding exposes paint that needs more drying. It definitely reduces bubbling.
I do use a CAT AAA. I still can't get the settings right. As I said I feel like I have started all over. Waterborne is a pain to learn anyway, I sure don't want to go through it again. I am going to call CAT and see if they have any recommendations since they work so closely with MLC.
I talked to someone from MLC sometime this past year after Plus came out. The "new" primer is the same as the original formula. However, the topcoat is different.
I use the clear Plus for the topcoat. I do not use the clear primer. I tried it once (rep gave me a test gallon), but did not see much benefit. To be fair, with my old gravity cup guns I did have to thin it a lot. I never tried it with my new pressure pot systems. The clear Plus seems to work ok for me. I have learned to do both topcoats on one side (the "back" side), then let set overnight. The next day I do two coats on the "front" or "show" side, then let set overnight again. Otherwise I get blocking marks from the drying racks.
For pigmented, I gave up on the original Agualente since I experienced mineral streak bleed-through with the primer too many times. That cost me $$$. I believe the primer for pigmented Plus is the same as the original primer formula.
I use MagnaClaw and HP White (tinted if needed) solvent borne for paint-grade projects. Very nice results with this combination.
