U.S. Art Supply Black Gesso Primer - 16.9oz (500ml) for Oil & Acrylic Paint - Superior Coverage, Canvas Prep, Mixable White Gesso Paint Artists

Very nice, and smooth coverage over the canvas. I wait about 20 minutes then start painting. I like painting wet on wet.

I’m going to enjoy experimenting with black gesso instead of always using white to cover my bare canvases. Seems to have a nice consistency.

works like a charm, but you are better off buying this through one of Amazon's many competitors, like I will from now on.

Perfect cover for PBN painting. Glides on easily, doesnt clump, and dries quickly and clearly. Makes it easier to blend the paint and cover the canvas so the final product doesn't look quite so "painted by number."

I do Paint by Number and was told to apply this prior to painting since the colors would go on better. I did. Frankly I don't know if it helps or not. However, it certainly doesn't harm the canvas and my paints seem to cover well. I do think the main thing is to buy your painting from a reliable company. Good qulity canvas, and paints that are true to the picture.

This has great coverage to cover up a plain canvas or a print you no longer want. It goes on easy ~ washes out of brushes easily. Dries quickly. I had a beach themed picture and wanted a contrast piece instead.

Easy to use, does good job, fair price for a big bottle

I like doing pbn but get so frustrated with not being able to get clean lines due to the roughness of the canvases. One coat of this was enough to make that possible and since it's clear it didn't hide the numbers. Game changer for the quality of the finished product.

Unused can be returned to container, very easy to apply onto paint by. Numbers canvas. Looks good so far
