what do i use to keep paint from spreading on canvas

The number one error all beginners make is buying a pre-stretched canvas or canvas board from a discount bookstore and not unwrapping the cellophane from information technology.

The number two mistake is leaving the sheet white when they start painting.

The showtime technique I always teach in painting (and a technique I use on 99% of my work) is to cover the white sheet with one solid paint colour which is called a ' toned basis'.

This is short for 'toned background' and is No. ane of my painting principles.

It can exist called a 'toned basis' or 'coloured footing' as it tin can exist used in cartoon and painting.

Using a coloured footing does a number of fantastic things that are not to be underestimated when starting to larn how to paint.

Information technology can transform your paintings by making them look more professional person, increase the speed in creating your paintings and give you a fool-proof method of creating a tonal mood in your work…Different artists throughout the ages have used toned grounds in their work,  from Turner to Jack Vettriano.

Turner used pre-coloured sheets of watercolour newspaper with different hues (colours) of browns, blues and greys.

When faced with a scene he would expect through his pre-painted watercolour sheets and select the most appropriate colour.

For example, a warm brown for an Autumnal tree scene.

You can utilize a toned basis (also chosen a coloured basis) opaquely or as a transparent stain (chosen an Imprimatura)

For our initial purpose  an opaque finish  is best as information technology stops the acrylic painting looking too 'watercolour'

Pro tip: It is applied afterpriming a canvas with gessoif you lot're working on a raw sail.

What colours do yous use for the toned basis?

It depends on the mood and feel you're after in your painting. You lot're trying to imagine what's underneath the painting and and so build opaque layers of colour ontop of this.

My preferred choice for landscapes, still life'due south or portraits about ever stem from 1 of the Earth colours. See: What are my paints made from?

Normally either Burnt Umber + white, Raw Umber + white or Xanthous Ochre.

For the absolute beginner, I recommend using Yellow Ochre.

Why?

It'due south usually included in most beginner sets and tin can be used diluted with a footling water.

It'due south likewise brighter than yous think so is good at taking yous out of your comfort zone.

Using Yellow Ochre can cause some hesitation if you lot are first starting painting as the xanthous tin can seem too potent, but you but need to have a lilliputian faith!

For example, if you are painting a blueish seascape the warm undertone of the xanthous can rest perfectly to the cool dejection in the scene, adding the feeling of the sun striking parts of your painting.

Pro Tip: If yous try using the Yellow ochre direct from the tube but still find information technology a piddling too strong in intensity for your taste simply add together some Titanium white to the mix to mute it down – it will give you a colour close to Naples yellow.

Are your watercolour techniques ruining your acrylics?

If y'all're coming to Acrylics or Oils from Watercolour you will naturally use too petty paint.

Watercolour is based on diluting, Acrylic is based on adding.

If you combine scratchy, watery paint onto a white canvass your painting will look non-expert.

If you accept the same scratchy watery paint on an opaque footing colour your painting will look rocking!

The coloured basis is doing all the work for y'all.

How does a coloured basis help me?

Bought canvases and boards are near always white.

When you have a white sheet any colour you paint onto information technology looks drastically unlike because of the optical effects and tricks colour plays on you.
As a beginner, this can be disconcerting. For case, if you paint a light grey onto your white canvass it will look black.

With an untrained artistic eye, it'due south really difficult to judge colours and tones accurately because of the effects of 'Simultaneous contrast.'

Pro tip: Have a await at the video half mode down this article to see the furnishings of simultaneous contrast

How much do I dilute my Acrylics? (and practice I just use h2o?)

It depends on the brand of pigment you're using.

Heavy trunk paint volition demand more water than a soft body paint. As I use this technique on most of my paintings I utilise a fluid acrylic from Gold paints. This has already been mixed in the factory to a thin consistency and has a skilful level of acrylic binder in the paint and a actually overnice strong saturation of colour. You lot can add a touch of water into information technology and it volition still hold the acrylic bail really nicely.

If you're simply starting with the technique using standard Acrylics will work fine.

Pro tip: Some manufacturers recommend you don't dilute Acrylics with more than than xl – 50%  water due to diluting some of the acrylics adhesive qualities (every bit y'all are diluting the amount of acrylic 'binder' in the mix). However, for this stage of the painting this doesn't matter, as we're painting direct onto the canvas. Nosotros want the paint to 'grab' onto the canvas and soak information technology. If you mix in too much medium at this stage it can cause a resist to the further layers of paint adhering onto them as hands. Continue the mix thin and 'lean'.

Pro tip: If you are finding the paint is pooling in pocket-size droplets on the surface when y'all are simply using water yous need to add a dash of 'menses release medium' (now called wetting amanuensis) to the paint. This will help to break down the surface tension and make the thin layer of paint soak into the canvas.

How do I employ an Acrylic Coloured Basis?

Fourth dimension :10 Mins

Level: Accented beginner

Materials:

Yellowish Ochre Acrylic pigment ( I demonstrate with Golden Acrylics Heavy body paint) white canvas or canvas board, decorators brush (I use a Purdy two inch decorators castor), kitchen roll (paper towel), water, newspaper, Cranked handle palette knife ( I employ a number 45 RGM palette pocketknife)

Pro Materials: (Tear off the disposable palette, Cranked handle palette knife ( I use a number 45 RGM palette pocketknife), h2o mister, Aureate fluid Acrylic.

So here's what y'all exercise:

1. Lay old newspaper on the floor, or piece of work on a really one-time flooring or table.

2. Mix the Yellow ochre in a jam jar/old mug or plastic tray with water until it's the consistency of milk/single cream. Student Quality paints will need less h2o than artist quality paints.

3. Grab some kitchen gyre in your left mitt (considering your jump to get some unwanted drips when you first start).
Pick upwards the canvas. Paint effectually the edges first, trying not to get likewise much overflow onto the front of the sail. Angle the brush to minimize beard sneaking over the front end of the canvas. Apply the paint with a scrubbing motion to 'push button it' into the canvass so it soaks into the canvas.

four. Place the sail on the floor or depression table. Then working quickly brush the paint from left to right to cover the canvas.

5. When you paint there will be darker streaks of pigment on the border of the canvas  because the bristles push it out. You have to keep working backwards and frontwards to smooth out the indiscretions.

6. squeeze the brush in the kitchen towel to take out nearly of the moisture and so gently go over the canvas again working from left to right, overlapping strokes and lifting the brush at the end rather than working dorsum and forth.

Watch out for drips on the side of the sail and if your too enthusiastic picket out for spray from the brush.

Pro Tip: I premix a whole airtight plastic container with a ground colour and then I don't have to mix the perfect consistency every time.

Pro Tip: If you are mixing the pigment and the water together don't employ the decorators castor, it will selection up too much of the paint and exist tricky to mix together. Try using a plastic kitchen spatula, old paintbrush

Pro Tip : I Use Golden Fluid Acrylic paint as information technology has a stronger staining effect than watering down Heavy trunk pigment.

Pro Tip: If using Acrylic footing for oil paint make sure you add h2o to the acrylic. As acrylic is plastic based it tin crusade a pare that the oil paint will sit down on pinnacle rather than sinking into the canvas.

Pro Tip: If you add too much paint to the initial layer the paint won't behave the same on the weave of the sheet.

So where practice nosotros go from hither?
You lot've unwrapped your sail and got a lovely coloured ground painted. Now we need to take a quick understanding of brushes so we have the right tools for the task.

Resource

These brushes are off the hook, bright for decorating at dwelling as well, come with a footling cardboard 'brush firm' to keep the brush in shape between uses. Look out for sets for sale every bit these tin exist really skillful value.

I predominantly use Gilt paints as I find the colour saturation actually skillful and the Titanium White has some amazing opacity. They also take a huge range of mediums, Gels & varnishes.
