Brief Description: Left Seat Ceconite, 4 - Painting
|
|
Painted the Ceconite covered left seat with Stewart Systems EkoPoly.
After letting the EkoFill cure for a couple of days, I lightly sanded it with a maroon scotchbrite pad, and cleaned it with the Stewart Systems EkoClean water-based cleaner. I had decided, mainly becasue I don't have an air compressor large enough for spray-painting, to use a foam roller to paint the seat. This is an acceptable method, and I talked to the Stewart folks about it at Sun N Fun. I wanted to try the roller to see how it works with the paint, as an alternative to spraying. I want a slightly textured finish for the interior of the plane (not shiny) so I thought this may be a good way. Overall it worked pretty well. But I did have some problems.
The water-borne polyurethane is "HIGHLY" susceptable to any oil or grease on the surface. The EkoBond fabric cement and the EkoFill fabric sealer worked very well, with no noticable response to any oils on the seat frame. But when I put on the EkoPoly - it just beaded up everywhere as if the seat had been waxed like a car. Especially right around the frame. I washed the first coat off because it wouldn't stick - a very positive benefit of the water-borne paint. I thoroughly cleaned the seat parts with the EkoClean again and washed them down with water. This helped, and the second try went much better - but it still fish-eyed around the rear of the frame. So there must have been some oil or something on the frame still - or oil from my hands - who knows. I'll have to make sure I clean the next frame much better before I put on the fabric, and maybe wear gloves (if they're oil-free!).
Rolling the paint worked pretty well. The instructions from the Stewarts on rolling call for using the finest the foam roller you can get, and then tipping out with a brush to remove the bubbles that pop up after rolling. This was a pretty good pain in the butt. I think for this application, just using a brush would have worked better. It tried brushing the left-over paint onto a piece of fab
