Sacrificial Graffiti Resistant Coating
PERMASHIELD SACRIFICIAL is a water-based modified wax emulsion that dries to a clear/transparent, non-yellowing tough film. It shields the surface from the penetration of spray paint, marking pens, chemical attacks, crayons, and lipstick into the substrate.
Tagging can be removed by using MONOCHEM CITRUS CLEAN (9700) or a hot water power washer. After the graffiti is removed and the substrate is damp, reapply PERMASHIELD SACRIFICIAL to the stripped sections.
PERMASHIELD is also available as a NON-SACRIFICIAL and PERMANENT (10-Year Warranted for unlimited graffiti removals) Graffiti Control System.

BASIC USES:
PERMASHIELD SACRIFICIAL offers a low-cost graffiti barrier. It may be used on interior or exterior, painted or unpainted vertical surfaces including concrete, stucco, and masonry walls, highway structures, shopping malls, civic or mass transit stations, municipal facilities, factories, office buildings, apartments, schools, libraries, etc.
PREPARATION:
- All surfaces must be clean, dry (< 15% moisture), free from adhesion affecting contaminants like dirt, wax, oil, grease, scale, efflorescence, loose or peeling paint,
- Cracks, gaps, seams, nail holes, or other imperfections larger than 1/16” must be properly filled before the application
- Concrete, stucco, and plaster surfaces must be cured for a minimum of 28 days before applying PERMASHIELD SACRIFICIAL.

NOTE: Red brick or stained deep-colored block might show haziness after applying PERMASHIELD SACRIFICIAL.
This accentuation is normal. Conduct a test patch for visual and performance approvals before proceeding with the entire job.

UNPAINTED SURFACES: Two Options:
OPTION 1: Application With Water Repellent.
- The surface must be unsealed and moisture-absorbent.
- Apply one coat of AQUASEAL ME12 to the entire exterior elevation (corner to corner or for taller walls under the product and for the first 15 feet above the cut-off line) and allow 4-8 hours to dry before applying PERMASHIELD SACRIFICIAL.
- AQUASEAL ME12 is used for protection against water penetration and to help neutralize the alkalinity of the surface, which causes the cracking and flaking of paint and coatings.
- Apply 2-3 coats of PERMASHIELD SACRIFICIAL wet-on-wet to the elevation as specified.
- Make sure the surface is pinhole free after the PERMASHIELD SACRIFICIAL is applied. If not, an additional coat will be required.
OPTION 2: Application without a Water Repellent.
- If PERMASHIELD SACRIFICIAL is applied to the substrate's entire elevation (corner to corner), the use of AQUASEAL ME12 as a sealer barrier coat can be skipped.
- Apply two coats (wet-on-wet) of PERMASHIELD SACRIFICIAL to the entire surface elevation. Porous and textured surfaces will require a third coat.
PAINTED SURFACES:
If the surface is painted for the entire elevation, skip AQUASEAL ME12, apply 2-3 coats of PERMASHIELD SACRIFICIAL, and conduct a test patch to ensure the proper adhesion and performance.
- To prevent bleeding, surfaces damaged with graffiti must be cleaned before applying PERMASHIELD SACRIFICIAL.
- Apply when the temperature is between 50°F and 100°F. Do not apply if rain is imminent within 24 hours.
- For the best application, use a conventional sprayer at the normal painting pressure with a tip size ranging from .010 to .015. Do not allow the product run-downs to dry on the surface. Pick up any excess material immediately with a dry roller.
- Do not apply too heavily; it will cause whitening or yellowing.
- Do not thin; apply at the packaged consistency.
COVERAGE:
Covers approximately 200-300 square feet per gallon. It will vary according to the surface texture, porosity, and application methods. Porous and textured surfaces such as block and stucco will require a third coat. Two coats are required for smoother surfaces. The surface must have enough coats to be pinhole free.
