THE PROCESS

GLASS STAIN REMOVAL

EVALUATE
The stain thickness is evaluated to determine the severity of the staining and the expected outcome result. The stained area is measured in square feet or square inches to determine the material use and the time of the job. Stained Glass is categorized in the following levels of severity:

LIGHT

MEDIUM

DEEP


SEVERE

The stain is not thick enough to obscure vision. Can be restored with no distortion and minimal abrasive steps.
The stain is a thicker layer than Light and the stain drops overlap to obscure safe driving vision. The stain can be removed with multiple steps with no distortion.
The stain is thick and widely overlapping. It appears like dried soap suds. Deep Staining requires multiple abrasive and polish steps to remove the stain build up and restore to clarity. The stain is white in color and widespread.
The stain is etched into the glass deeper than 3/100th of an inch and visible distortion will occur by removing the stains to the bottom of the etching.

EVALUATE THICKNESS & AREA
The stain thickness is measured to determine the abrasive steps that are needed to removed the buildup without creating distortion. The stain area is measured to determine the time spent using each abrasive step and estimate the total time of the job. The thickness of the glass can be measured throughout the process using an Ultrasonic Instrument.

MASK & PROTECT
The work area is completely covered with painter’s mask, plastic on the bottom and absorbent on the top, and taped into place. Carpets, walls and fixtures will be protected in buildings. Vehicles are masked to protect the paint from any overspray.

REMOVE STAIN
The initial scratch is removed using the least robust abrasives necessary that remove the stains in increments of less than 1/10,000th of an inch per application. When the stain is completely removed, the glass may be opaque and/or white from the abrasion.

RESTORE CLARITY
Clarity is restored by applying lesser abrasives in diminishing stages to create a smoother surface to the glass. As each application of lesser abrasive is applied, additional clarity is achieved. This process can be from one to three steps of various abrasives.

RESTORE FINISH
Using foam pads the final polish is made with a mixture of rare earths and oxides to remove the residual haze from the abrasives and restore the like-new clarity of the glass.

CLEAN
All masking materials, tape and debris is collected in waterproof containers and removed from the site. All polish residue is wiped clean. There is no trace of work being done in the area.
