How to Stretch a Canvas for Painting

Monday, December 4th, 2017

When I first started painting, the thought of stretching my own canvas was frightening, but after a few attempts of stretching a canvas it came to me automatically. I was able to make canvases for half the price of store bought ones. Also, stretching your own canvas can trigger off the beginning of the creation through the hands on process of doing it yourself. Hope this helps.

Materials and equipment

Pre- made stretcher frame/ or self-made

Canvas material cut 10cm approx larger than your stretcher frame

Canvas staple gun

How to Stretch a Canvas

Lay your canvas on a flat surface wrong side up then lay your stretcher right side down on top of canvas. Pull the sides of your canvas up and round to the top of the stretcher.

DIAGRAM 1 Secure the 4 points with staples or tacks to create a diamond shaped wrinkle in the canvas. Check diagonals and adjust the stretcher for squareness before going further.

 

CANVAS DIA 1DIAGRAM 2– Secure the canvas to the stretcher with staples approx. every 6 cm. around the edge, working from the center points outwards. Pulling the canvas as you go. Continue working out to the corners in this pattern. Do not overstretch the canvas. When applying tension, the canvas pliers should not be forced to pull the canvas in place. The tension of course will become greater as you work towards the corners.

CANVAS DIA 2FOLD– the corners under; as neatly as you can, leaving no exposed tab that maybe caught and damaged. Staple or tack excess canvas that wraps around to the back of the frame.

HINT– Once finished and your canvas and is not as tight as you would like, fill a small spray bottle with luke-warm water and spray the canvas on the back. Once dry your canvas will be as tight as a drum. Happy painting!

Homemade Gesso Paint!

Saturday, November 18th, 2017

I love Gesso paint and use heaps of it in my work. It’s gritty, chalky and can be applied to artwork to give a translucent or opaque look. It’s also very expensive so I decided to make my own.

 

Gesso is used for many things such as a primer for canvas or on paper to give a good base for painting, drawing or mixed media work.  When making collage I use it as a gluing medium to stick on papers, in-between, painting and drawing layers.

The recipe below makes 2 litres of Gesso paint

( If not using straight away, this Gesso will last approx. 4-6 weeks)

Homemade Gesso

PLASTER MIX

1 cup Plaster of Paris or fine white plaster powder

1 cup of PVA or white glue

1 cup hot water

PAINT

3 cups white acrylic paint

UTENSILS

Container, cup and mixing stick or spoon

RATIO: 1-3

Plaster Mix 1 – Acrylic paint 3

Method

To make the plaster mix. Add the plaster to the hot water and stir ( Safety purposes: always add the plaster powder to the liquid, not liquid to plaster, as it will blow up into your face and always wear a dust mask)

Dust Mask

“Plaster of Paris” and cup

Hot water and mix

Next add the PVA or white glue, stir.

Finally add the white acrylic paint and mix. ( I used some acrylic powder paint I had and made it up with water) You can use any kind of acrylic paint or colour .

 

Result

I was very happy with the result. The gesso is translucent with the gritty bits I like. You can also do several layers of gesso to give a more opaque appearance. It covered my canvas very well with only 1 coat. When adding more than 1 coat you can sand in- between to give a really smooth surface for detailed work .
