About
Glazing:
Glaze refers to a substance that is thinned to
create a transparent or translucent film of color. Diluting any
paint substance, tinted varnish or tinted water essentially can
produce a glaze.
Oil-based glazes should be applied over an oil-based
undercoat of the color of your choice. Eggshell sheen is preferable, but never
use a flat (matte) finish.

Wall surfaces:
A variety of
decorative effects can be created using oil-based glazes. For wall surfaces the
glaze essentially stays the same in composition. Only the color and fluidity of
the glaze varies.
Method of
Approach -
On large wall surfaces it is generally necessary for at
least two people to efficiently apply and work the glaze. Though oil glaze is
slower to dry and hence has an extended working time, it will still set up
rather quickly. A first-time
glazer may find darker areas appearing as irregular lines, known as ‘burn’
marks. These occur because the glaze must be methodically applied in segments,
always moving from top to bottom, then across the wall in a regular fashion
(see diagram).
Glazing application diagram for wall surfaces

Apply glaze in irregular sections.
This insures a random overall appearance and helps diminish potential 'burn'
lines (glaze build up from section to section).
For
Striee glazing and dragging
the wall application methods vary. Refer to the wall diagrams in the appropriate
section.
When a new segment is started, the area previously treated has
already begun to set. With the application of glaze on the new segment, a
buildup of color may appear and create a ‘floating line’ where old meets
new. This is unattractive and may
interfere with the overall look of the textured or faux glaze appearance.
However, it is an effect that is overcome with experience and can
usually be avoided if an area can be used for “practice” before a big
project is begun.
Always start the glaze application in the least
visible area of the room. As you continue glazing, a rhythm is achieved and the
overall appearance of the glaze treatment improves.
Application:
Using two glazers, saturate rag with mineral spirits and work over surface to allow
glaze to flow freely. Wear respirators, gloves and protective clothing. Once
the surface is damp the first artist should begin by applying the glaze
with a brush over an area only large enough to create the desired finish.
Keep the exposed areas ‘wet’ by leaving a buildup of glaze. The
second glazer should begin the desired finish (color-wash, rag-roll, striee,
etc.) while the first artist continues
the glaze application on the next segment. Working in tandem, they should
continue until the wall area is completed, without resting. Clean up any excess
glaze that may appear on adjoining (and yet untreated) walls with a rag
moistened with mineral spirits.

Wall edges:
Apply glaze to within ˝ inch of wall edge and work to edge with a dry brush.
This should prevent you from getting any fresh glaze on a previously treated
wall surface.
Important Tip - How to fix drips and spills
–
If wet glaze gets onto an area that has already been finished and has begun to
set, it may dissolve the previous finish. Simply blot area with a dry rag to
remove excess. Any attempt to repair area before completely dry may result in a
mess that is virtually irreparable. Small areas are manageable. Large areas may
require the complete area to be removed then re-treated
Small area
repair - Once completely dry (24 hrs.) fresh glaze may be touched in
with an artist’s brush until desired results are achieved.
Large area
repair - Treat before drying is complete.
If a large area of glaze is affected and begins to burn away, or
dissolve, the removal of the entire glazed surface may be required. To do this,
dampen a rag with mineral spirits and wipe surface until clean, using multiple
rags if necessary.
Alternatively; you may allow wall to completely dry (24 hrs.) then
repaint base coat and begin again.
WARNING
- Always dispose of rags and waste spirits appropriately. To find a
