For the most part I am very happy so far with spraying with General Endurovar. This is my first time spraying finish so I do expect some learning curve. I am spraying the finish on my A&C bathroom vanity so everything except for the vanity frame was laid out on tables on painter's pyramids and given 3 coats as it was all horizontal work. This includes the top, 8 slats, 2 doors and 1 backsplash. All of these turned out very well and I am pleased with the finish. But my issue is with the vanity frame as this has vertical surfaces and I am having some issues with running. Of course the runs have occured only on the front and the side that will face out into the room as opposed to the back and the side that faces the walls in the corner. In my discussions with my friend at the local Rockler store as well as the General Finishes rep at the Las Vegas woodworking show they said to spray it undiluted which is what I did.

 

So any suggestions on how I can do better on vertical surfaces?

 

I am using a small cup sprayer hooked up to my compressor running between 50-60psi which is what the directions call for. I also have a dedicated hose for the sprayer to avoid cross contamination and dust and a dedicated water/oil seperation filter.

 

Thanks.

There are several things that can cause the runs on the vertical surfaces. One is too much product being spayed. You may have to adjust back a bit. I usually setup a piece of cardboard and spay on it till I get the setting where I want it. I also had a person that was demonstrating spray guns to give this tip. Close the adjustment that controls the amount of product and then turn it 1/4 turn 5 times and start at that point. It has worked pretty good to give me a consistent starting point.

You might also be too close if you are getting run or moving across the surface too slow. It is one of those things that you just have to experiment with how it works best for you.

 

The cardboard thing has helped me get it pretty close or a scrap piece of 1/4" plywood.

 

And as usual the runs as you said are always on the side that shows, never on the side against the wall.

You have to spray just wet enough before it will run. Takes lots of practice. For me, a raking light is key. If you can take a hanging shop light and hook it to the shop wall between shoulder and belt high where you spray. Then you will be better able to see how much finish is going down. Google a few automotive paint spray booths to see how they light their spray booths.

 

.....ugh the runs!!!!!

 

By spray the finish straight from the can without thinning as was suggested. The finish has more stick or hang time.

I agree with John and Ace. I use a HVLP sprayer myself, but have been painting cars for years. The too close, too much is most likely whats causing your problem. To get rid of the runs, you will have to sand then out, sorry but that's they way. Once the runs are gone sand the surface again and apply light coats. Just enough to get it wet and no more.

Allen, all the advice above is right on. With water base, you have to respray the whole front. You cannot just touchup the area like with a solvent. One thing is it does sand easy. Good luck and let us know how it goes. bob

Thanks for the input guys.

 

After my first coat I realized that I needed more light than what I had so I brought in my portable construction light that is on an adjustable stand with 2 halogen lights with adjustable heads. That made a very big difference especially on the flat work. On the vanity frame I had to spray a side and then rotate the table it was sitting on in order to see it well. Today I will sand things out and will probably just brush the areas with the runs as the probelm areas are on the legs and cross pieces as opposed to the side panels which turned out fine.  

Allen don't brush it.    At some point again you will have that spray gun in your hand again. Why not keep pushing through and get things worked out. Don't get disappointed, you can do it!
