MLC Pigmented Agualente Stacking Issues1/16
Current finish schedule I am using on MDF.
- One coat Agualente stain blocking primer (two coats on fronts) 3-5 wet mils per coat
I have discovered that stacking products is a very touchy issue with this product.
I finished 80 pcs of 6" wide MDF T&G for an island back just before Christmas. The products stayed racked in the heated drying area while I escaped for Florida for 6 days. When I got back I had the guys pack up the parts and deliver to the jobsite. I got a call two days later when the carpenters opened up the packages and all of the boards were adhered together. I discounted this issue when I discovered that the guys had wrapped everything face to face with nothing between. I fabricated more T&G (the boards were literally breaking apart) and shipped after two days drying time with packing paper in between and packed front to back. I wrapped them lightly and asked them to open them up as soon as they arrived. No major issues, but they noted that even the paper stuck in areas! Keep in mind that these items were wrapped up for less than 4 hours!
Since this time, I have discovered that the primer with even stick to itself or paper after a day or more of dry time. Using fabric sheets is a no go as well as it will literally imprint the fabric in areas. I am at at loss...especially when dealing with product finished on both sides.
MLC PI sheet shows 4-6 hours for stacking and although I would never push that I am concerned that something is going on.
I haven't had this issue in the past when using the Agualente clear topcoat. Should I be topcoating the color with clear? What would you recommend using when packing or stacking parts? Wax paper??
In a few months, this will be a non-issue, as I will be going back to nearly 100% CV in my new booth/shop location. However, I would like to know if this is something others are experiencing.
Yep, pretty typical for most WB finishes and some brands are worse than others. A full cure takes closer to 3 days. Regular masking paper in between should do the trick. For the record, I'm a regular user of Agualente. I like the product, but I avoid stacking my finished parts.
You'd think that a cabinet grade finish would have these issues addressed.. This stuff passes all the KCMA tests, but I can't help but be concerned with overall durability if it's exhibiting these issues a week or more after application.
