My daughter asked for a desk to do her homework. I had an extra peice of MDF laying around so I used PVA to seal it. I then sanded it to a very smooth finish. I was quite impressed with the results.
I gave the desktop a day to dry completely and started with the painting. I choose an oil based enamel from Home Depot and sparyed it for the first coat. I then used a ROS to sand it smooth. I have spayed the second coat and the top look great, but I am able to take my finger nail and make and impression in the pait. It's been over a week since I painted the desktop and I'm suprised that I can make an impression with my finger nail.
What did I do wrong???
The PVA method was quick and easy. Was there a better choice of paint?
Any help would be appreciated.
