Just a quick pick… I wanted to share my successful experiment.
It is one of my mixed-media acrylic paintings I had been working on for a long time… I was not sure about material I used for the textured effect and let it sit in my studio for months, just to make sure that finished painting will not have any problems with time.
It is 12×12 in canvas heavily textured with “Flex bond” and flexible Modeling paste. For me it was an experiment. “Flex bond” is a Crack Prevention Mortar which I used in my home tiling project. If it flexes to prevent cracks in tiles, why not to try it on canvas?!
First I prepared the mixture of Mortar and water following directions for the product exactly how it is recommended for tile work. Paste like consistency mortar I applied to the canvas using a palette knife. Texture was interesting already. Right away I made impressions in mortar using different found objects. I let it dry for two days and covered surface with black gesso. I had already decided to paint a night scene, and black gesso provides a perfect rich ground.
After next two days of drying I examined my canvas: everything looked great, no cracks or peeling off the base. Mortar was adhered perfectly. I even hit it a few times like a drum to check if it may crack or break and was very pleased to find no problems with the canvas. It was ready to paint.
Then I decided on composition and added some more texture for the rocks in foreground for my future seascape. This time I used Molding paste (didn’t want to prepare the Mortar mix again for such a small amount needed). This part I covered with black gesso, too.
Here is the close up detail of the painting. I named the piece “Vivid sunset” and considering all this beautiful unexpected texture, painted it in semi-abstract style.
This painting will be available in my online Etsy shop.
Later I used the same Mortar mix for bigger canvases (two 20”x24”canvas painting).I did not risk to cover entire canvas as heavily as I did for my 12”x12” painting, to prevent future sagging, because Mortar has more density than acrylic mediums. Lightly applied Mortar on small areas of a big canvas works fine.
