I have been working with medium-texture canvas. I applied about 4 coats of Gesso (liquitex brand, the best I can find locally). Despite all the coats, the canvas' texture still makes it through. I even sanded one of the layers.


When bright pictures are panned on-screen, the texture shows through. I would appreciate any advice on getting the smoothest surface on canvas. I was unable to find any finer-texture canvas that is available in 72-inch widths.

safaa,


That's an interesting idea to check out. I was originally looking for any creative ideas to smooth out a canvas, such as using powdered gesso, mixing it thick, applying it and then sanding it. The liquid gesso just does not go on thick enough or I am missing something.

Hi Rich,

Why start with canvas to begin with? If you're going to paint it anyway, is there a strong reason you want to start with canvas and not some of the other smooth cloth choices that have been discussed here?

Bandrsnatch,


I was unable to find the blackout material locally in the width I need. The Home Depot drop-cloth is not wide enough and has a middle seam. I went to cloth stores and only found single-layer blackout clock that felt cheap. I did not find any other decent alternatives.


I could also use a stretchable cloth that could be painted. I am mixing my own paint, using regular and pearlescent paint, and the test results so far have been very good.


This is my first choice, followed by the ever-popular Parkland Plastic sheet...
