Step 1
To create the marble effect on your canvas, you’ll need at least two different shades of acrylic paint. You can make your own shades by mixing colours with white acrylic paint.
Step 2
Before painting, protect your work surface with newspaper or a plastic dust sheet. Prepare the canvas by painting the entire surface with a pale base shade using a paintbrush. Allow to dry.
Step 3
Mix the glazing fluid with your paint using the ratio recommended on the pot – generally around two parts glaze to one part paint. The consistency may take some trial and error to get right – it needs to be easy to pour, without being too thin.
Step 4
Prop your canvas onto upturned cups or egg cartons at each corner and place a drip tray or plastic sheet below it to protect your work surface. Pour the paint glaze mixes onto your canvas one by one, then move and tilt the canvas around so the poured paint spreads and mixes together to create the marble effect.
Step 5
Once your paint is dry, you can add some light finishing touches. Use a small feather brush and white paint to create the veined look of real marble, or add some darker shades to create different bands of colour. Use an artist’s brush to add a few small blobs of the paler base colour to break up the fluid lines of the main colour.
Step 6
Once you’re happy with the result, leave the artwork to dry, then finish with a coat of polyurethane varnish to seal and protect your canvas.
