Hi all, I am using a HVLP sprayer to do my kitchen cabinets. I am using Inslx Cabinet Coat mixed with Floetrol and water (1/1/1). The Cabinet Coat didn't recommend thinning, but it was just way to thick to put through the sprayer that I have (Wagner Control Sprayer Model# 0518080). I spayed my first coat of paint and and it's a disaster! All over the doors are these little areas where the paint just DID NOT STICK...see picture. primed/sanded/primed/sanded/primed/sanded with cleanings and dustings in between all of them. The "craters" seem to form around where there are grooves in the wood door from the oak grain of the cabinet. Oddly enough, the paint seemed to adhere to the actual groove part, but not any of the surrounding area. Please does any one know what's going on? I've already put SO much work into this project, this is the last thing I need.

I did use an oil-based primer, but I didn't think this mattered since I read that you can use just about anything over an oil-based primer. I also didn't have any trouble with this when I was painting the kitchen cabinet boxes. I did not add any thinner then.

Please note that I was not laying on the paint as heavy as it looks in this picture. The heavy paint shown is a result of me trying to compensate for the craters on this particular cabinet. The craters happened even with just a very thin layer of paint.

Good thought! But not it.



Hi Bud- Yes, that would make sense, and from the picture it would appear that could be a culprit. However, there is a consistent pattern of this happening around where there is a deep grain in the wood, and also where there are gouges or nail holes So unless I went and specifically put my fingertips on each of these spots, I don't think that is the case! Thank you for your thoughts though!

Some of the new formulated paints and thinner especially Flotrol don't play well together. If you need to thin just use water. I have a couple small HVLP sprayers sitting on the shelf in the garage gathering dust. I thought they would be great for small jobs, but they created more problems than they solved. And most of them were from thinning.

I went back to airless no more thinning eliminated almost all the problems. To get real HVLP results it takes like a 4 stage unit and that gets quite pricey.

Crater Update

Hi Again!

Update on the cabinet doors. I attempted again this afternoon to spray the doors. This time I used the very minimum amount of thinner and only used water (not Floetrol). The cabinets turned out BEAUTIFULLY. They are still drying so they still have a little bit of leveling to do, but I can already see that the finish is going to be smooth as glass and not a "crater" in sight. So it looks like either too much thinner or the Floetrol was the culprit or a combination of the two.

In response to the above posts about the HVLP sprayers. In general I would tend to agree with you, but I did my research and bought this sprayer specifically because it was designed to use with heavier (generally latex based) paints. As a DIYer and not a professional contractor, I just couldn't afford to spend all that $$$ for a fancier sprayer. The finish might not be AS GOOD as it would have been with one of those, but it looks like it will be good enough for my tastes. And is sure is an improvement over rolling/brushing in terms of finish and time!

THANKS EVERYONE for your input on this!!!

I may have to buy one of those guns. They're cheap enough.
