   Deft is not water based, it's nitrocellulose lacquer but it can get milky for a different reason than water based finishes. With the water based, you don't want multiple coats. Actually, most finishes don't want to be done in more than 2 or 3 coats. It's not the thickness of the finish that gives depth, it's flattening and polishing it, so it acts like a lens.

   Thanks for the reply hammer1.  I understand that Deft is not a water based finish. I was trying to understand if there was any benefit or disadvantage to applying more coats on the water based finishes. I usually use oil based varnishes. These water based finishes are new to me.

   Hi GRW, I've had mixed results with the water based products. I've used quite a few different brands including WB sanding sealers. Most of the manufacturers don't recommend building multiple coats. They seem to give the work a blue or green cast if you do. In part this is due to the actual color of the product. It also can be caused by second coating too soon, trapping the solvents. Some add a little dye to the product. Some shops are using curing ovens.There are also some hybrid WB finishes that are very popular. They have an amber tint, are less toxic than solvent finishes, great durability and a workable surface. Below are a couple of the more popular brands. http://www.vtcoatings.com/topcoats.html

   Thanks Hammer1,

   I just completed a kitchen with Oxford EMTech 8000, one of the Target coating products. I had good luck with it. I put samples side by side with my oil varnishes, and the customer chose the Oxford waterbased products.  I want to switch to water based finishes, but have little experiance with them. I know what I did on this project, and I know the result. It helps me to understand what would/can happen if I change my finishing process by adding coats and such. I want to get the best results from this finishing process, and with help from good folks like you I can climb the learning curve much faster.

   In High School I was a finisher for a 2 man WW shop. I learned alot in those few years. But when I stared working there the finishing process was already in tact.  They knew what they wanted, and just asked me to do it. (the owner was a retired chemist from Exxon, and knew his stuff). Now I'm trying to build my own new process. New spray equipment, finishes, methods, and in time a new spray area. Having help from people who have graduated from the school of hard knocks(knots) sure does help.

   Thanks much,

   GRW
