Sacrificial Coating SC-1 Anti-Graffiti Shield

Sacrificial Coating SC-1 – Removable Anti-Graffiti Barrier for Building Surfaces

Sacrificial Coating SC-1 is a clear, water-based sacrificial coating engineered for graffiti control on most building surfaces. It forms a removable barrier that prevents spray paints, crayons, and ink from penetrating and staining the underlying substrate. Designed for contractors and facilities professionals managing chronic graffiti exposure, SC-1 is formulated as a water-thin liquid suited to spray application on porous and textured surfaces. Once graffiti is removed, the coating can be reapplied the same day to restore full protection.

Unlike permanent anti-graffiti coatings or abrasive removal methods, SC-1 is sacrificial — it is removed along with the graffiti using PROSOCO Graffiti Remover, SafStrip, or high-pressure hot water, eliminating the need for chemical strippers or abrasives that can damage surfaces or the surrounding environment. It does not darken, alter natural color, or add shine or gloss, making spot reapplication seamless across an existing facade.

Key Features & Benefits

Broad Surface Compatibility

SC-1 is suitable for masonry, wood, metal, and most painted and synthetic surfaces, making it a versatile solution across a wide range of project types. Contractors can apply a single product across mixed-material facades rather than specifying separate coatings for each substrate.

No Color or Appearance Change

The coating does not darken or alter the natural color of treated surfaces and adds no shine or gloss. This is critical on historically sensitive structures or architecturally detailed facades where visual impact must be minimized, and it allows for spot reapplication without a noticeable change in overall appearance.

Same-Day Re-Protection

After graffiti removal, SC-1 allows same-day reapplication to restore the graffiti barrier. For high-traffic or chronic graffiti locations, this minimizes downtime and keeps surfaces continuously protected.

Good UV Stability – Minimum 5 Years Exterior Performance

SC-1 is formulated with good UV stability, providing a minimum 5 years of exterior performance. This long service life reduces the frequency of baseline reapplication on protected surfaces that haven't been tagged.

Breathable Protection

Protected areas remain breathable, preventing heavy buildup on the substrate. This is particularly important on masonry and other porous surfaces where moisture vapor transmission must be maintained to avoid long-term surface damage.

VOC Compliant

SC-1 is compliant with all national, state, and district AIM VOC regulations, with a VOC content of less than 30 g/L as a low solids coating. This ensures the product can be used on projects in the most restrictive regulatory jurisdictions without special approvals.

Common Applications

Chronic Graffiti Zones on Masonry

SC-1 is well-suited for brick, concrete, and stone surfaces in high-vandalism areas, allowing repeated graffiti removal and recoating without surface degradation.

Metal Surfaces

Painted and bare metal surfaces such as utility boxes, railings, and panels can be protected with SC-1, with treatment possible 20 minutes to one hour after cleaning.

Wood Substrates

SC-1 can be applied to wood surfaces to prevent graffiti staining, providing a removable barrier that does not alter the appearance of the wood.

Painted Surfaces

Most painted and synthetic surfaces are compatible with SC-1, allowing graffiti protection on previously finished walls and panels without stripping or refinishing.

Porous and Textured Surfaces

The water-thin liquid formula is specifically designed for spray application to porous and textured surfaces, ensuring adequate penetration and even coverage on rough substrates.

Application Instructions

Surface Preparation

1. Protect people, vehicles, property, and all surfaces not meant for application from product, splash, fumes, residue, and wind drift.
2. Remove spill and overspray immediately from horizontal surfaces, as they will become extremely slippery.
3. Ensure the surface is clean, dry, and absorbent before application. Do not apply after rain until the surface is thoroughly dry.
4. If cleaning is needed, use the appropriate PROSOCO cleaner. For previously painted or metal surfaces, most can be coated 20 minutes to one hour after cleaning. Other surfaces should be allowed to thoroughly dry before treatment.
5. On unpainted surfaces previously tagged with graffiti, remove graffiti using PROSOCO Graffiti Remover or SafStrip. Rinse thoroughly. Application of SC-1 can begin once the surface appears dry.
6. On painted surfaces previously tagged with graffiti, cover graffiti with a fresh coat of paint. Let the new paint dry thoroughly per manufacturer's recommendations before applying SC-1.

Temperature Requirements

1. Surface and air temperatures should be between 40–90°F (4–32°C).
2. Do not apply during rain showers. Protect freshly coated surfaces from rain for two hours following application.

Equipment and Application

1. Apply using a garden tank sprayer or conventional airless spray equipment. Adjust tips and pressure for a wide spray pattern.
2. Use only low pressure for application. Do not atomize.
3. SC-1 may also be applied with a brush or roller.
4. Always test each type of surface for suitability and results before overall application, including any previous repairs, patches, and aesthetic cementitious finishes.

Storage and Handling

1. Keep from freezing. Store in a cool, dry place.
2. Always seal container when not dispensing.
3. Do not alter or mix with other chemicals.
4. Maintain storage temperatures of 45–100°F (7–38°C). Do not double stack pallets.
5. Dispose of unused product and container in accordance with local, state, and federal regulations.

Technical Specifications

Frequently Asked Questions

Q: Can SC-1 be reapplied the same day graffiti is removed?
A: Yes. SC-1 allows same-day re-protection after graffiti removal, minimizing downtime on high-traffic or chronically vandalized surfaces.

Q: Will SC-1 change the appearance of the treated surface?
A: No. SC-1 does not darken or alter natural color and adds no shine or gloss. Spot reapplication can be made without a noticeable change in overall color or appearance.

Q: What is the recommended method for removing graffiti from SC-1-protected surfaces?
A: Graffiti is removed using PROSOCO Graffiti Remover, SafStrip, or high-pressure hot water at a minimum of 180°F. After removal, the coating must be reapplied to restore the graffiti barrier.

Q: Is SC-1 suitable for horizontal surfaces?
A: No. SC-1 is not suitable for horizontal surfaces. It is intended for vertical and near-vertical applications only.

Q: Can SC-1 be applied over existing water repellents?
A: No. SC-1 is not suitable for application over existing water repellents.

Q: How long will SC-1 perform on exterior surfaces?
A: SC-1's good UV stability provides a minimum of 5 years exterior performance on surfaces that have not been tagged and required removal and recoating.
