Decorative Finish Techniques
Slower drying paints are an advantage when blending large areas so that a “wet edge” is available for working the paint. If a multi colour blend consisting of say 4 colours is to be applied, they should be mixed and brushed onto a test panel first. What you are looking for on your test panel is:
a. Colour difference is visible when viewed from the appropriate distance.
b. Suitable opacity from the colours.
c. Viscosity is correct.
1. Coatings should be applied by brush or roller, a brush is used to blend these colours together.
2. Then a stipple brush is incorporated to produce the final blend and also remove any brush marks. Blending may be used on decorative panels as a finish in itself, or as a background to a sign or similar. Panels can be done as bands from the top to the bottom of an area, or from the centre of a panel moving out to the perimeter of the area. Use opaque colours or translucent glazes.
1. Bands of Colour Blended Together
2. Colours Blended from Centre of Panel to the Permeter
Most important is that the cloth be “lint free”. Most suitable are muslin, cotton, linen. The cloth should be reasonably absorbent and colour fast when used with solvents. Newspaper would also qualify as a rag in this area. A common tool to use is a chamois leather.
The decorator should asses the job and determine the type of glaze which is most suitable, keeping in mind the size of the area to be worked, if it is a one person operation or more, conditions regarding temperature. A water Of oil glaze should then be chosen
1. Apply the glaze to the surface with brush or roller then it should be stippled to give an all-over even appearance. If the glaze has been applied by roller there is no need to stipple. (Two people are an advantage on a large area).
2.The cloth/chamois chosen should then be rolled up into a sausage shape, and then rolled over the surface, changing direction as you move and rearranging the folds in the cloth to avoid monotonous print. The rags should be changed as they become soaked with glaze.
3.The other system of creating a pattern with a rolled up rag is to do it in reverse. This time the same type of cloth is used, but it is firstly rolled into the glaze, then the decorator proceeds to roll the rag over the dry ground thus creating a patterned effect as the rag deposits the glaze onto the surface. Care must be taken to achieve a similar all over effect if this method is used.
Note: Rags used for this purpose should never be left about at days end in a crumpled heap, especially if flammable thinners have been used. They may ignite spontaneously, dry them out or put them in a covered tin with water.
