White Wash Spray Painting Technique

White washed book case

White washing furniture has become very popular. By spray painting with a water based paint, a very smooth and professional look is possible. It is also very fast and you can be sure that the end product will be very pleasing.  I have done this with the book case shown here. The inside shelves have been painted in solid white to produce a professional effect.

The following materials are be needed:

• Off-white Acrylic paint
• Water based clear varnish
• Sand paper - 220 grit and 360 grit
• Wood filler
• Paint remover
• Dry cloth

Depending on the state of the piece of furniture, you will have to prepare it by doing the following:

• Remove all hardware from the piece of furniture
• Remove old paint or varnish by sanding with 220 grit sandpaper
• If necessary, use paint stripper to remove stuborn varnish or paint ( remember to nutralise paint stripper with wet cloth when finished)
• If necessary, fill small nicks and scratches with wood filler and sand down to a smooth finish
• When bare wood is visible, finish off with 360 grit sand paper to get smooth surface

When the preparation is complete, wipe down the piece to make sure that no dust or grit remains. You can now proceed with spray painting . I use an air spray gun with a big enough nozzle to spray thick Agrylic paint. I also use a water-based varnish. These can be diluted with water and produces a very nice, smooth finish. Do not dilute too much to avoid paint from running. The process is as follows:

• Seal the wood with one coat of water - based varnish
• When dry, flatten unevenness with 360 grit sand paper to a smooth finish
• Dilute paint with water - 10% water
• Spray lightly over whole piece of furniture
• Try and avoid praying edges too heavily
• The inside shelves are painted to a solid white finish

After painting, leave for at least 12 hours to completely dry the paint. Now the fun part starts. Sand down certain areas and edges with 360 grit sand paper to expose wood surface.

The last step is to seal the piece with water-based clear varnish. I find that at least 2 coats are needed to get a nice finish. It should be noted that not all wood is suitable for washing. Pine has a nice solid wood grain that shows up nicely when sanded and lends itself to white washing.

Tip: Always work along with the grain of the wood and try to avoid circular movements.

PAINTING OLD FURNITURE

 How to prepare the wood for painting

  Painting old furniture is easier than many people think. It gives a professional look and gives your old furniture new life. The first step is to prepare the piece for painting. This is a very important phase of the process. The quality of the finished product is totally dependent on the thoroughness of preparation of the wood surface. A distinction is made between new and previously painted wood surfaces.

Preparation Techniques

 1. New unpainted furniture:

New furniture needs only to be smoothed with a fine sand paper such as 220 grit.  If there are any scratches or chips, fill with wood filler . Allow to fully dry. Sand smooth with 220 grit sandpaper, always sanding with the direction of the wood grain. Clean the wood surface with a dry, damp cloth to remove dust particles. Let wood dry.The piece is now ready to be painted, varnished or stained. 

2.   Old painted, varnished, stained or waxed furniture:

Before used furniture can be painted, all old paint or varnish must be removed to the original wood surface. Firstly, remove all hardware such as handles. Depending on the amount of old paint, use a coarse sand paper such as 40 or 60 grit to remove old layers. If this does not work satisfactory, use paint stripper. Paint stripper is a dangerous substance to work with. Read and follow the manufacturer’s instructions carefully. After the old paint is removed, fill all dents with wood filler and sand with finer sandpaper such as 220 grit. Clean the surface with a dry, damp cloth and let dry. The piece is now ready for painting.

Remember that before applying the final coat of paint, the wood must first be primed or sealed. I use a water based clear varnish. Wait until the varnish is dry, sand down lightly and clean before applying final coats.
