A. Apply 1-3 coats of our primer, ONE COAT ™. You should clearly see evidence of the primer on the wall after it has dried to the touch. You have sealed the base of the material/substrate.

ONE COAT™ - PRODUCT APPLICATION DIRECTIONS FOR ND GRAFFITI SHIELD SYSTEM™:

DIRECTIONS FOR USE ON OLD AND NEW PAINTS, HOUSE PAINT, WOODS, VINYL, METALS, SIGNS, WALL COVERINGS, FURNITURE, ALL MASONRY, AND OTHER SMOOTH AND ROUGH MATERIALS AND SUBSTRATES AND OVER OTHER APPLIED COATINGS.

NOTE: USE THE RECOMMENDED SPONGE SYSTEM BELOW. SMOOTH AREAS MAY HAVE BUMPS, GROOVES, INDENTATIONS, ETC. USE A QUALITY SPONGE MOP IF ALL THESE AREAS ARE SMOOTH. A FINE BRISTLED BRUSH CAN BE USED FOR HARD TO REACH AREAS. A urethane type sponge mop is available at hardware/paint/janitorial stores. This is a very soft sponge with no holes on top. It is very resistant to tearing and cracking. It is available with a wringer and on a pole.

Our glossy version of ONE COAT™ does not need shaking. The satin/matte finish version requires vigorous shaking in small containers. Use an electric drill to mix it in 5 gallon pails for about 5 minutes. Test mixed material appearance after mixing by spreading it on a small inconspicuous area. The appearance should look dull.

1. Pre-clean all materials (new or used) with a neutral cleaner (PH of 7) to degrease and remove all soils and residues before sealing with ONE COAT™. Allow cleaned area to dry. Use a fan indoors to speed drying.

ON SMOOTH AREAS:

2. For small areas, apply product directly to sponge mop and squeeze out excess into clean tray or bucket. For larger areas, pour product into tray or bucket. Dip sponge mop directly into product and squeeze out excess with handle. Sponge mop should be damp with product, not soaking, nor dripping.

3. Apply product dampened sponge mop directly to the paint/material to be sealed and draw the sponge across the surface. Treated area should look wet. Do not rub the product on the area - doing so can disturb the film which forms quickly! Blend in any "runs" or "drips immediately. Continue applying the product until you cannot see the wetness of the product. Dip the sponge mop back into the product, squeeze out excess product, and continue the application.

4. Start at the top far end and move the wet sponge mop across from one end to the other. Then, repeat this technique until you have reached the bottom. Use sponge mop with or without pole for convenience.

5. We suggest that you apply 1-3 separate applications depending on the porosity of the substrate. Non-porous surfaces require only one application, semi-porous and some porous substrates require 2 applications. There are some porous substrates that require 3 applications of ONE COAT™. Allow each application to thoroughly dry to the touch before applying the next one.

6. Rinse the sponge mop in water to avoid it being sealed and ruined by the drying sealer after use.

ON ROUGH MATERIALS SUCH AS BRICK:

1. Use an airless sprayer with 13" or 15" reversible tip at 300-500 psi. Or, use a clean brush.

2. Spray mist the product over the area. Seeing the wetness of the product as applied is sufficient coverage for each coat.

3. When the first coat is "dry to the touch", repeat the procedure above to apply the additional coats.

 
VERY IMPORTANT:

Do not use yellow colored sponges either new or used with rough surfaces to spread ONE COAT™. Use a smooth surface urethane type sponge material, which is commonly available at hardware/paint, and at janitorial supply stores. Pre-rinse the sponge and allow it to thoroughly dry before dipping it in ONE COAT™. Use a painters foam pad brush for applying ONE COAT™ to walls and for touch ups to any area. Rinse and allow the foam pad brush to dry out before use.

Keeping the sponge/pad resting in a quantity of WET ONE COAT™, as in the bottle/container, will prevent the sponge/pad from drying out while you are waiting for any single coat of ONE COAT™ to dry out thoroughly. Wring out excess wet ONE COAT™ from the sponge/pad before applying the next coat so that the tool is damp with ONE COAT™, not dripping wet in ONE COAT™.

It is extremely important NOT to rub ONE COAT™ around on the wall with the tool! Simply move the tool across the area in one direction until you do not see any more wetness, then, rewet in ONE COAT™, and continue. Allow each coat to be thoroughly DRY TO THE TOUCH before applying the next coat.

 

B. Apply 4 coats of our ND GRAFFITI SHIELD™, one at a time so that each separate coat is absolutely dry to the touch. On a warm sunny day outside, each coat can dry in minutes!

Note: If you are sealing a very porous surface - do this test: Apply only 1 coat of ND GRAFFITI SHIELD™ on a very small area and wait for it to completely dry. If it dries clear - proceed with the rest of the job and apply all 4 coats of ND GRAFFITI SHIELD™. If, however, the small area does not dry clear, and looks whitish, that means that not all pores were sealed with ONE COAT™, and therefore you need to do one more application of ONE COAT™ before using ND GRAFFITI SHIELD™.

ND GRAFFITI SHIELD™ APPLICATION DIRECTIONS:

The substrate must be first primed with ONE COAT™ Water Based Primer/Sealer/Finish in sufficient quantity so that it is visible and can be felt on the surface. After it is dry to the touch apply ND GRAFFITI SHIELD™ by spray (airless sprayer with 0.015 or 0.013 tip at about 300-500 PSI is recommended for most large painted and all porous surfaces; low pressure hand pump sprayer at about 35 PSI could be used on very porous surfaces). The application should be thin and ND GRAFFITI SHIELD™ should appear water clear when applied. THE GRAFFITI SHIELD SYSTEM™ is a total of 4 separate coats of ND GRAFFITI SHIELD™ over the base application of ONE COAT™. Each coat must be dry to the touch before next coat is applied. Drying time may vary between few minutes to an hour depending upon the weather, humidity and ventilation.

THE GRAFFITI SHIELD SYSTEM™ should be used after 96 hours which is the cure time. You can protect the wall while it is curing by covering it with a drop cloth or securing the area. Should cleaning be necessary before 96 hours, reapply ND GRAFFITI SHIELD™ to the needed areas only. Do not allow this product to freeze and do not use it in freezing temperatures. However, once it is applied and cured, freeze/thaw cycles will have no effect on proper product performance.

Remove new graffiti from THE GRAFFITI SHIELD SYSTEM™ in 24 hours or less for better results. Use our DISAPPEAR Organic Graffiti/Adhesive Remover™ - apply to area and allow it to soak on graffiti for 5 minutes to about 15 minutes and flush with water, clean with a soft cloth, or powerwash the area. When necessary, touch up cleaned areas with a light coat of ND GRAFFITI SHIELD™.

Please test this product on a small inconspicuous area before proceeding with the job.

WARNING: THIS PRODUCT CANNOT BE ALLOWED TO FREEZE IN THE CONTAINER AS IT WILL RUINED WHEN THAWED!

 

Questions - Answers

*The best method to determine the spread rate for these products on your material is to pre-test them on a small inconspicuous area. Our estimates should not be relied on to be accurate for your application.

How do I remove graffiti from The Graffiti Shield System™?
Use DISAPPEAR Organic Graffiti/Adhesive Remover™. Apply it to the affected area. Let the remover soak on the graffiti for 5 minutes to about 15 minutes. Do not use any abrasive pads, brushes. Then, remove the loosened graffiti with a powerwasher, or, soft cloth and then rinse with plain water. Reapply our remover and repeat, if necessary. You should be able to remove most graffiti without any damage to the shield. If you observe any change in appearance of The Graffiti Shield System, after the cleaning simply add a coat ND GRAFFITI SHIELD™ to the affected area. We recommend that you remove all new graffiti within 2-3 days.

Can it be damaged when removing graffiti?
Yes, using wrong remover can even strip it. Abrasive brushes, or not following our directions can damage it. It can be scratched as anything else. Simply reapply more ND GRAFFITI SHIELD™ to the affected areas after the graffiti removal, which will blend into the look of the rest of the wall without any seams.

How do I apply it on different types of materials?
A. On smooth materials such as paints, signs, vinyl use our recommended sponge mop because you can cover large areas in minutes. Fill a painter's tray with our product. Dip the sponge mop in it. Squeeze out the excess so it is wet, but not dripping, and apply over the area until dry spots are seen. Repeat the procedure covering the entire area. Spread any runs and drips immediately before they dry. When finished, clean the tools in plain water.
B. On porous materials use an airless sprayer with a 13" or 15" self cleaning reversible tip at about 500 PSI. With a fine bristled brush blend any runs or drips immediately. Clean the tools with plain water.

How should I clean the "Shield" from normal dirt and soils?
Hose it down, or scrub it using plain water, or with a neutral cleaner.
