Product Description
MuralShield is designed for the protection and conservation of fine art acrylic murals. It offers UV protection, consolidation, and weatherproofing.
It will restore a weathered, uncoated mural, and is recommended for the preservation of new acrylic and aerosol murals. It is a conservation-grade flexible coating designed as a protective and isolation layer. However, it will not protect against graffiti vandalism alone.
For long-lasting, durable graffiti protection, World's Best Graffiti Coating must be applied over MuralShield. Once a mural is preserved with MuralShield, World's Best Graffiti Coating is easily applied as a sacrificial barrier for graffiti protection, enabling quick removal of all types of graffiti vandalism without damage to the underlying surface.
The final outcome will be a highly maintainable, durable, vibrant mural.
MuralShield builds up to a gloss finish. For a satin finish, apply 2-3 coats of World's Best Graffiti Coating over MuralShield.
Muralshield is compatible with artist-grade acrylic paints, fine art aerosols, collage-based, or digitally printed murals. Compatible substrates include building structures such as uncoated concrete, wood and signage grade panels, most exterior insulated finishing systems (EIFS) and stuccos, CMU block walls, brick walls (depending on the brick condition), painted and coated surfaces.
Features & Benefits
- Long-Lasting Preservation: Provides durable UV protection, weatherproofing, and is compatible with various mural substrates, it enhances the longevity of new artworks.
- Superior Mural Restoration & Protection: Revives color and flexibility in sun-damaged murals and strengthens weakened paint binders.
- Paintable Surface: Can be painted over indefinitely with an additional coat of MuralShield applied to newly painted sections.
- Preparation for Painting: MuralShield can also be used to prepare concrete, CMU, stucco, and both painted and unpainted walls for painting. Apply two coats before gessoing or priming.
Application
- Surface Preparation
Allow the newly painted artwork to thoroughly cure before applying MuralShield. Ensure the surface is clean, dry, and free of contaminants. - Apply MuralShield
Apply a first coat, lightly misted (fog coat) using using an airless spray gun (515 spray tip recommended), HVLP, or acetone rated compression sprayer. Apply two to three generous coats, allowing at least 20-30 minutes of drying time between coats. Make sure to overlap your passes to ensure a thorough coating. - Graffiti Protection
For comprehensive graffiti resistance, apply World's Best Graffiti Coating over the cured MuralShield Matte. This combination creates a sacrificial barrier that allows for easy removal of graffiti without damaging the underlying mural.
Coverage Guidelines
Approximately 300 sq. ft. of coverage per gallon on painted or unpainted surfaces, depending on the substrate and application technique, for 2-3 coats of the product. (For example, an 800 sq. ft. mural will require 2-3 gallons of MuralShield).
Exact coverage varies depending on type of stain and the porosity of surface material.

Instructions for Use
Use the product as supplied. Shake well before use.
Do not dilute or add water to the product. Do not apply product with water-wet sprayer or recently washed equipment, over dew or moist surfaces, or when there is a possibility of rain or very high humidity.
MuralShield should only be sprayed using an airless spray gun (515 tip recommended), HVLP, or acetone rated compression sprayer. Remember MuralShield contains solvents and sprayers should be compatible with clean hoses, so residual paint does not dissolve in the line.
It is best practice to mask and protect windows in a suitable manner.
Application
Begin by testing MuralShield on an inconspicuous section of the mural. You should see a noticeable increase in color vibrancy and luster. Allow to dry. Use adequate solvent-rated masks, protective goggles, and solvent-rated gloves.
Apply by airless spray gun, Gravity Feed or Siphon HVLP spray guns, or Acetone-rated pump-up Sprayer. Using rental equipment is discouraged. Should it be used, inspect for paint contaminants in all hoses, containers, and fittings. Dry paint within spray equipment should be thoroughly removed before spraying MuralShield. Avoid applying MuralShield with brushes or rollers as the coating may damage the artwork.
Step 1 Allow a newly painted artwork to thoroughly cure before applying MuralShield.
Step 2 Apply a first coat, lightly misted (fog coat), to ensure initial wall adhesion.
Step 3 Apply two to three generous coats of MuralShield, allowing at least 20-30 minutes of drying time between coats. Make sure to over lap your passes to ensure a thorough coating.
Step 4 Allow the final coat to dry thoroughly for at least 1-2 hours before applying World's Best Graffiti Coating (WBGC). Apply at least two coats of WBGC (or more if the artwork is highly susceptible to vandalism) using a clean HVLP sprayer. Use a paint brush to gently fan out any drips or beading.
For additional instructions on how to apply WBGC, see World's Best Graffiti Coating.

Small Scale ‘Tag’ Removal Jobs (When used with World’s Best Graffiti Coating)
Step 1 Use Heritage Graffiti Remover, Sensitive Surface Graffiti Remover / Safewipes. For removal of spray paint Heritage Graffiti Remover is the best choice. Apply with a solvent-rated brush. Agitate the graffiti with your brush as the product is applied.
Step 2 Wipe away dissolved graffiti with a damp toweling cloth.
Step 3 Once satisfied with the results, thoroughly rinse the affected area and allow the surface to dry. Re-apply two to three coats of World's Best Graffiti Coating by spray, roller, or brush.
Large Scale Graffiti Removal Jobs (When used with World’s Best Graffiti Coating)
For large scale removals, such as bombs, heavy tagging, filled in bubble writing, buffed or painted over murals.
Step 1 Work in sections of 5-10 sq ft. Apply Heritage Graffiti Remover using a pump-up sprayer, nylon brush or broom, and agitate.
Step 2 You will see the graffiti gradually dissolve on the surface. Rinse the dissolved graffiti using a pressure washer with a 25º tip maintaining a distance of 6” - 12” away from the mural surface in order to ensure no damage to the acrylic paint layer.
Step 3 Any remaining graffiti can be spot cleaned using Heritage Graffiti Remover or Sensitive Surface Graffiti Remover and a nylon bristle brush.
Step 4 Once all graffiti is removed, rinse the entire mural clean. Allow 15-30 minutes before reapplying World's Best Graffiti Coating.
Step 5 Apply two coats of World's Best Graffiti Coating by spray, roller, or brush.
Restoring a Coated or Uncoated Mural
Step 1 Remove sacrificial or non-sacrificial coatings.
Contact the original artist and collect any historical information on the mural or artwork. Follow appropriate methods for obtaining artist permission as per the Visual Artist Rights Act, 17 U.S. Code § 106A. Follow conservation procedures and American Institute of Conservation Code of Ethics and Guidelines for Practice. Document and assess the condition of the mural for any delamination or sensitive areas.
Secure delaminating areas prior to removing any graffiti. Identify any previously used graffiti coating. If it is a sacrificial coating, follow the manufacturer’s instructions for removal. If it is a non-sacrificial coating, contact the manufacturer for best removal practices. Remove the previous graffiti coating and go on to Step 2.
Step 2 Test the condition of a mural.
Assess the condition of the mural by wiping the acrylic paint layer with a damp white cloth. A damaged binder will release a substantial amount of pigment. If you are able to wipe off a substantial amount of color, avoid washing the mural with harsh chemicals or pressure washers. Go to Step 3.
If a little color comes off of the mural, consider using a biodegradable soap, and a low PSI pressure wash with a water temperature of 80-150ºF (26.67º -65.56ºC".
Step 3 Apply MuralShield.
Apply 2-3 coats of MuralShield. You should see a significant color shift in damaged areas.
Step 4 In-painting.
Select an artist grade acrylic paint. We suggest using Golden Artist Colors. Proceed as per normal conservation practices.
Step 5 Reapply MuralShield.
Apply 2-3 coats of MuralShield. Follow the application instructions in the section, “How to Apply MuralShield.”
Step 6 Apply World's Best Graffiti Coating.
Apply 2-3 coats of World's Best Graffiti Coating. Document the final conservation results.
Modifying a Mural Previously Coated with MuralShield and World's Best Graffiti Coating
Step 1 For touch-ups or artwork modifications, or in-painting projects, thoroughly remove World's Best Graffiti Coating (WBGC) by using Heritage Graffiti Remover with a cold or hot pressure washer at 120°F / 49°C - 200°F / 93°C. You will see a visible difference in the areas where WBGC has been removed.
Step 2 Test your mural by lightly scraping the surface with a blunt blade or fingernail. If you do not see a waxy residue on your tool, then you are ready to commence in-painting.
Step 3 Allow the freshly painted areas to thoroughly cure.
Step 4 Apply two to three generous coats of MuralShield to the entire mural, followed by two final coats of WBGC.
Preparing New Walls
For Uncoated or Unpainted Walls
Step 1 Wash an uncoated wall using TSP (Trisodium Phosphate and / or biodegradable soap. Allow the surface to thoroughly dry.
Step 2 Apply 2-3 coats of MuralShield.
Step 3 Gesso or prime the wall surface.
Step 4 (Optional) Reapply 1-2 additional coats of MuralShield.
For Coated or Painted Walls
Step 1 Assess the condition of the coated or painted surface. If the coating or paint easily delaminates off of the wall, consider removing this first. If there is adequate adhesion, wash the wall using a bio degradable soap and allow the surface to thoroughly dry.
Step 2 Apply 2-3 coats of MuralShield
Step 3 Gesso or prime the wall surface.
Step 4 (Optional) Reapply 1-2 additional coats of MuralShield.
Caution
Before commencing any large scale coating application, be sure to test thoroughly on an inconspicuous area to determine finish and compatibility with your materials. Please be aware the use of solvent based sharpies for outlining your mural may bleed through paint after application of MuralShield. We do not recommend using sharpies for this reason.

Thank you for all the help and guidance! Protecting our murals for many years to come!

It does not make any sense to put so much time, effort and creativity into a masterpiece and not seal it. Mural Shield is that Glaze and its made to amaze! Not only does it hold up and keep your work vibrant for many years but it also brings your work back to life if you are looking to restore it. This product should be the go to for every mural. I highly recommend and is always satisfying to apply as the last step in any creation. Use a good respirator and clean off your surface prior to application. You will need an industrial grade sipon and pump hose that holds up to chemical grade applications. you can find those spray nozzles at a hardware store. Tune to a fine mist and apply gently and evenly across top to bottom. Set dry and hit it again for a good second and even coat.
use gloves , face shield, respirator and paint clothes. Do Not Breath this in. Read all the instructions and run a test swatch. Excellent choice for all your works on walls. add to budget on comissions as its worth its weight in gold.

This is a fantastic product for preserving murals. We painted our mural with acrylic paints on concrete board and sprayed it with this product. Nothing has cracked, faded or peeled. We could not be happier!
