HELP! I had a concrete ceiling "plastered" smooth; I then primed it with a milky substance to decrease absorbancy. I tried putting a semi-glossy white latex on (2 coats), but it looked bad in the light, so I then put on flat latex over. The first coat looked almost OK, except for some skips and lap marks. The next coat looked worse. I am using top-of-the-line paint, lambwool roller, taking time to do it well. Why do I keep getting lap marks and skips? Is my technique so lousy? A local painter told me to start from the window end of the room and work across perpendicular to the light. The ceiling is about 210 sq. ft.

I have heard of a process called rose-on, but have been unable to find much information.I would really appreciate any information that one might have. I was told about a product called Flotrol. I was told that it can be used in place of the glaze, but they did not know what ratio to use or if you had to use something else with it ,as well as the paint. I watched a video that suggested that if you add water to your paint you get a translucent appearance like the glaze is that so? I called the number on the back of the flotrol and asked if the flotrol would give a tranclucentappearance like the glaze does and the lady told me no. If water would give such a look why wouldn't the flotrol, or does it, and the lady just is not that familiar with it? Help I need more information,please.
