PITCH PINE WOOD GRAINING WITH DONAL QUIGLEY

Donal Quigley is an Irish painter and decorator who has a passion for wood graining and tells us about his process and techniques for reproducing pitch pine.

ABOUT DONAL

Donal Quigley is a third generation painter and decorator from County Kilkenny in Ireland.  His apprenticeship was served under the guidance of his father in the eighties and after completing his training, Donal founded his own decorating business in 1992.

Besides the standard painting and decorating work, Donal found himself working in more and more specialized areas such as hand painted signs, gilded hand-carved signs and sandblasted glass signs as well as different wall finishes.

In 2014, Donal studied at the SWR Decart Studio in Dublin under the tutelage of Michel Nadai, the respected French decorative painting artist.

For the past five years, Donal has found himself focusing on wall panelling systems due to their growing popularity in Ireland.

WHAT IS PITCH PINE?

pitch-pine-floorboards

Indigenous to the United States and the eastern seaboard in particular, the Pitch Pine can grow upwards of 60 feet and has a lifespan of some 200 years.  A hardy species, not even fire or severe trauma can destroy it.

The reason for its centuries old popularity is due to its high resin content.  Indeed, as well as being used for woodwork, the pitch pine is a source for turpentine and tar, otherwise known as pitch!

These days it has a less glamorous purpose, being used for fuel, pulping and making crates.  In the past however, it was used to create anything from railroads and wooden ships to church pews, panels and flooring.

Pitch pine is not a strong wood and has a rough texture to the grain, however the high resin content leaves it resistant to decay, hence its popularity.  The resinous nature of the wood has its down side however, as it makes it difficult to machine and sand.

Previously pitch pine was sought after due to the vibrant shades and figuring of the grain, however since the boom of railroads and mass planting and forced early foresting of the trees, the quality of the grain began to suffer which is why it is currently used for less elegant tasks.

As a result, the only way to obtain finer specimens is through reclamation, which means in turn that demand has outweighed supply causing a worldwide shortage and rising prices.

This has led to a resurgence in demand for painted reproductions to match already present architectural elements.

  1. Begin to form the figure.

2

  1. Join the sap and continue up.

  1. Main figure is now formed.  It is important to soften after each line is drawn to avoid smudging into the next line.

4

  1. Now using some burlap begin to do the side grain.

5

  1. Glaze the other side.

6

  1. Then burlap to form tight side grain effect.

7

  1. Finished central panel.

8

  1. Next tape off top rail.

9

  1. Pencil in figure and soften as you go.

10

  1. Finish rail.

11

  1. Repeat process on lower rail.

12

  1. Last two styles to do.  These can be plain straight grain if you prefer.

16

  1. Add a thin line of colour to emphasise the joints.

17

  1. Overglaze with same colour, adding some Vandyke brown to create      highlights and moirés.  Then badger lightly.

DECORATIVE SANDBLASTED AND REVERSE PAINTED MIRRORS

2013-11-12 17.59.56

Mike O’Regan fitting the reverse painted pub mirror!

 

As a natural progression from the traditional sign writing side of my business, I developed an interest in reverse painted and gilded glasswork and have been honing techniques and styles ever since.

Here is a brief introduction into some of the work I have been commissioned to produce and an insight into the skills and methods I am learning and developing while doing so.

SANDBLASTED AND REVERSE PAINTED MIRROR

I was commissioned by a local public house to produce a vintage style oval mirror featuring the name of the establishment.  As I had produced many pieces for them previously, I was given a free reign with the design, the only condition being that it featured green and gold.

The first step was to come up with the design, ensuring that it both kept to the client brief and was a workable design using the method I had selected.

Once approved, the design was vectorized and produced on my plotter to cut a vinyl mask in reverse for the back of the mirror.

The mirror itself was then completely masked for protection so that only the cut away parts of my design were visible.  I then sandblasted the design into the mirror using a standard glass etching abrasive and fortunately I have the use of an industrial sandblasting cabinet for good measure!

The masking was then removed and the mirror cleaned with methylated spirits before painting.

At this point, the mirror could be framed and reverse lit if one so wished, however this one was for painting so I decided to use metallic gold paint sparingly on the shadows of the lettering and some of the minor details.  Hammerite was used in this case as it is has a thick consistency so a single application gives the required coverage.

A golden tone of gloss paint was used on the acanthus design and of course the required green was applied – ordinary oil based gloss paints are fine for this. My trusty mahl stick came in handy for the detailed picking out process, both to steady my hand and to keep it out of the wet paint.

Once completely dry, the painting was backed up with an oil based undercoat and the mirror framed and fitted onsite.

STRIPPED PAINT AND CHEMICALLY REMOVED SILVERING

This is a slightly more tedious process due to modern strippers taking on average two days to remove the backing paint from the mirror in order for you to work directly on the silvering.

It does however, open up a whole new choice of techniques as you can oxidize, antique or completely remove the silvering once you have it exposed. An added bonus is that Gold leaf can be applied to stripped areas without losing any of its lustre as it would with a sandblasted piece.

Here is an early experimental project that was distressed a bit more than I would have liked, however you can see how sharp the graphics look and the effect of the gold leaf.

For this example I produced a ‘sea shanty’ mirror using a graphic that I liked the look of so I just vectorized in a sign program to make it useable.  I wanted this piece to have an antique rustic appearance about it, and was very pleased at how it came out.

The backing paint was removed from the mirror using paint stripper – it is important to let it soften completely, then carefully scrape it off using a plastic scraper to prevent the silvering underneath becoming damaged.

Once the paint is off and the glass is cleaned with methylated spirits, a cut vinyl stencil is applied as in the previous project.  All other exposed areas are masked off for protection.

I removed the silvering through the stencil using household bleach at full strength.  This is best done with a cotton bud and wearing gloves of course!  In a matter of seconds, the silver dissolves.

Once the area has been de-silvered the glass is thoroughly rinsed under cold running water to remove all traces of bleach. The stencil can then be removed.

I decided to antique the piece at the edges and this was accomplished by gently dabbing wrinkled newspaper in bleach then applying to the silvering.  Again, rinse immediately in cold water.

The glass was then backed up with a chestnut brown spray paint (Painters Touch) to add colour to the clear areas and protect the remaining silvering.  I then made my own frame as detailed below.

A BRIEF NOTE ON ANTIQUING THE FRAME

The frame for this piece was made of pine which was then whacked about and beaten and bruised with a wire brush and other implements.  A rough coat of black satin was lashed on and force dried with a heat gun to make it blister.

Crackle glaze was then applied and dried before top coating in powder blue. The heat gun was then applied immediately which caused the dramatic cracking effect.

A wash of walnut wood stain was then applied and sanded when dry.  The wash reactivated the crackle glaze and some of the powder blue flaked off to reveal the black.

When completely dry I applied a coat of oil based matt varnish to strap down the layers.

As an afterthought I added patinated corner brackets to give the look of an aged frame that had been reinforced.

I hope you enjoyed following these processes, more to come!
