Correcting errors in Watercolour

One of the very many Myths surrounding watercolour painting is that ‘you can’t correct mistakes’…

At the off,  let me say that this is completely untrue. If you react quickly with a slightly moist brush, clean water and tissue you can, say lift off splashes in your perfect sky with this method.

WHAT IF SOMETHING MORE DRAMATIC IS NEEDED ?

Let’s take one of my recent disasters I painted recently (thankfully they are few and far between these days), but it happens to us all.

This is the painting in question, over-worked, little tonal value, no light source, dodgy shadows etc. etc.

So I decided to remove the whole painting, what I call ‘The Sink Treatment’. If you are unhappy with a small section, that can be lifted of with a moist brush and tissue. You may only be unhappy with, say the sky, if this is the case you can simply remove that offending part using the same sink method.

Let me say at this point, that most pigments do stain, in varying degrees depending on the colour, so you will never get back to pure white paper. Also in my case I had painted the stone wall using permanent ink so that stayed put.

STEP 1

Run the tap until it is luke warm, this helps loosen the pigment.

STEP 2

Use a hogs hair (oil) brush or a stiff bristled household paint brush,  gently go back and forth over the painting until the pigment starts to move. Tip your board at an angle so the paint falls into the sink. If you are too vigorous you can damage the surface of the paper.

STEP 3

Keep repeating until you are either happy with the results, or until the water runs clear.

STEP4

Clean around your board with tissue, and let it dry naturally. I would only recommend this on paper taped to a board, if not the paper may cockle badly as it dries. Mop the water from the tape, and the painting with kitchen roll.

Don’t forget to keep checking the tape to ensure it’s still sticking until it’s completely dry.

Once you have done the ‘sink treatment’ you end up with a pale ghosty image, giving you an ideal ground to start again. I ended up with a misty image which gave me an idea for the subsequent painting.

The following day, I re-painted the painting, using White Gouache to create a misty atmospheric picture I was happy with.

This was the finished painting called ‘Misty morning in the Bluebell Woods’.
