Product Use Instructions 

APPLICATION SURFACES

Use for the final removal of inks and certain spray can stains on painted and coated surfaces, plastics, concrete, cinder block, terrazzo, stone, marble, granite and most other surfaces. Do not use for cleaning aluminum or alkali-sensitive surfaces such as polished floors

Removing Ink and Dye Stains:

After removing as much of any graffiti marker as possible, pour a small quantity of FELTPEN FADEOUT (FPFO) into a small bucket and then apply as thickly as possible to the remaining shadows with a nylon brush. When shadows have disappeared, wipe clean with a damp toweling cloth.

On all smooth or porous surfaces including signage, plastics, stone, concrete, granite or marble, you must attempt to remove as much of the graffiti as possible by first applying SENSITIVE SURFACE REMOVER (SSR), in the case of marking pens, or BARE BRICK, STONE AND MASONRY REMOVER (BBSM) in the case of spray can paints.

The time taken to work completely will vary from instantly, to several minutes, to even overnight in some cases.On inks or dyes splashed or thrown onto concrete, brick or porous surfaces etc., it may be necessary to leave FPFO on overnight. When doing this, we suggest applying FPFO as thickly as possible and covering with black plastic. You can tape the plastic to the wall along the three bottom sides first, and then brush on as much FPFO as possible before sealing the top of the bag onto the wall. This will keep the product wetter for longer, as well as prevent anyone from rubbing up against the wall on the affected area.

Occasionally, some markers or spray can paint shadows may not appear to have been affected by FPFO. However, wiping off with a damp cloth in the case of smooth surfaces or pressure cleaning in the case of brick, stone or masonry surfaces can achieve quite surprising results. Do not be concerned if you need to apply this product more than once.

Removing Spray Can Stains:

FELTPEN FADEOUT is extremely beneficial in removing certain spray can stains on porous masonry and concrete. After dissolving as much graffiti as possible with BBSM, an application of FPFO during or after the final rinse will eliminate any remaining pigment or stain in the surface.

This method (which is illustrated in the sequence below) can be used on a variety of spray can colors, however it is especially useful on RED spray cans and ANY color containing red, ie: oranges, pinks, purples and browns. These colors all contain fine red oxide pigments and are the most likely to leave a residual stain. The stain can be easily removed with a generous application of FPFO.

Once FPFO is applied thickly to the stain, the fading process normally takes only a few minutes to less than half an hour, but longer dwell times may be necessary. Fortunately, once you begin to see the stain disappear (even marginally) you can fade the rest, so be patient and reapply FPFO if needed.

DILUTED CLEANING APPLICATIONS

FELTPEN FADEOUT (FPFO) can be used as a high foaming cleaning concentrate with bleaching action when diluted with water.

Dilute with water as follows:

Light soilage 1:100

Regular cleaning 1:20-50

Mold removal: 1:20

Heavy soilage: 1:10

1. Make up desired diluted solution of FPFO.

2. Wash the surface with solution.

3. If surface is rough, scrub the solution in with a nylon brush, try to reach into crevices.

4. Rinse with clean water. Dry or leave it out to dry. To remove oil or grease spots, scuff marks and hard to shift spills, use FELTPEN FADEOUT neat.

TIPS FOR EFFECTIVE USE OF FELTPEN FADEOUT

TIP 1. On painted walls FELTPEN FADEOUT can be applied first to thick feltpen markers without agitating with the brush. Immediately after this, apply SENSITIVE SURFACE REMOVER in the normal manner. The FELTPEN FADEOUT will absorb the dissolved staining inks thus avoiding ghosting.

TIP 2. Any spray can graffiti that changes color when BARE BRICK, STONE AND MASONRY REMOVER is applied, will also be affected by FELTPEN FADEOUT.  Many shadows will disappear if FELTPEN FADEOUT is applied during and after BARE BRICK, STONE AND MASONRY GRAFFITI REMOVER application. Remember to look out for subtle changes in colors such as greens turning grayish yellow and reds turning crimson. The effect of this technique can appear to be magic, leaving onlookers totally gobsmacked!

TIP 3. Boot polish markers (recognized by thin drips running down vertically from the ‘tag’) and some posca pens (recognized as chalky–style water based marking pens) are best removed with FELTPEN FADEOUT. Wet the tag first with water, leave for a minute or two, then apply FELTPEN FADEOUT. Either wipe, or pressure wash off depending on the surface type.

SAFETY ISSUES

FELTPEN FADEOUT is corrosive to skin and may produce severe burns if in contact with skin for extended periods. Wear protective gloves, clothing and safety glasses as shown in SDS.

CAUTION

1. Always wear alkali protective gloves, goggles and long sleeve clothing.

2. Always know where water is available in case of a splash.

3. Avoid splashing FELTPEN FADEOUT on clothing as it will bleach / burn holes in cotton and other fabrics.

ENVIRONMENTAL CARE

FPFO is non flammable, phosphate-free and biodegradable. FPFO conforms to all statutory

environmental requirements for graffiti removal including VOC limits. Designed to be fast, effective and non damaging to surfaces. If necessary, water can be collected using a wet vac and disposed of safely. We believe nothing other than rainwater should enter our precious storm water systems.

CAUTION

Before commencing any large scale use, always test first in an inconspicuous area. This product is designed to remove all types of markers and stains, and may have an

unpredictable or even damaging result on certain man-made or stained surfaces. If necessary wait for surface to dry to ensure perfect results.

What is FeltPen graffiti remover?

FeltPen Graffiti Remover (often called “Fadeout”) is a specialized cleaner designed to remove ink, dye, and marker stains left behind after graffiti removal. It targets the “shadow” or “ghosting” that remains after spray paint or marker has penetrated a surface.

What does FeltPen remover do that other graffiti removers don’t?

Most graffiti removers remove the bulk paint—but not the stain underneath.

FeltPen is designed to:

• Pull ink and dye out of the surface pores
• Eliminate ghosting and shadow stains
• Remove stubborn pigments (especially reds and dyes)
• Finish the job after primary removal

It’s a second-step product that delivers a truly clean surface. Can be used along side Bare Brick Stone & Masonry Graffiti Remover or Sensitive Surface Graffiti Remover, dissolving as much of the graffiti as possible (choice of remover depends on type of substrate). For help on YOUR project reach out to us at 630-675-4509 or [email protected].

When should I use FeltPen graffiti remover?

Use it after removing the main graffiti layer.

Typical process:

1. Use a primary remover (like Bare Brick for spray paint)
2. Rinse or wipe off
3. Apply FeltPen to remaining stains or shadows
4. Allow dwell time and rinse or wipe clean

It’s specifically designed for final cleanup and stain elimination.

Does FeltPen remove spray paint?

Yes—but it’s best for residual spray paint stains, not heavy coatings.

It works especially well on:

• “Ghosting” left after spray paint removal
• Red, pink, orange, and purple pigments (hardest to remove)
• Light overspray or embedded pigments

For thick spray paint, use a primary remover first.

What surfaces can FeltPen be used on?

FeltPen works on both porous and non-porous surfaces, including:

• Walls
• Driveways
• Fences
• Commercial Buildings
• Transit Stations
• Highway Overpasses
• Train bridges
• Concrete Driveways

It’s one of the few products designed to work across multiple surface types safely.

Will FeltPen remove graffiti shadows completely?

In most cases, yes—with proper application.

For best results:

• Apply generously
• Allow sufficient dwell time
• Reapply if needed

Deep stains may require multiple treatments, but the product is specifically designed to eliminate shadowing that other removers leave behind. With purchase, Exterior Performance Coatings offers free application consultation to schedule reach out to us at 630-675-4509 or [email protected].

How do you apply FeltPen graffiti remover?

Basic steps:

1. Apply thickly to the stained area
2. Let it dwell (minutes to overnight for deep stains)
3. Keep the surface wet for best results
4. Agitate lightly if needed
5. Wipe or rinse clean

For deep stains, covering the area can help extend dwell time.

Can FeltPen be used by itself?

It can—but it works best as part of a system.

• Standalone: Light stains, marker, dyes
• With other removers: Heavy graffiti or spray paint

Using it after a primary remover gives the best overall results. Can be used along side Bare Brick Stone & Masonry Graffiti Remover or Sensitive Surface Graffiti Remover, dissolving as much of the graffiti as possible (choice of remover depends on type of substrate). For help on YOUR project reach out to us at 630-675-4509 or [email protected].

How much area does FeltPen cover?

Coverage varies by surface:

• Up to 1,000 sq ft per gallon (smooth surfaces)
• Around 300 sq ft per gallon (porous surfaces)

More porous surfaces require more product and possibly multiple applications.

Can FeltPen remove other stains besides graffiti?

Yes—it’s multi-purpose.

When diluted, it can clean:

• Grease and oil
• Smoke residue
• Carbon buildup
• Mold and mildew
• Food and organic stains

It functions as both a graffiti remover and heavy-duty cleaner.

Is FeltPen safe to use?

It is effective—but strong.

• Biodegradable and VOC-compliant
• Corrosive in concentrated form
• Requires gloves and eye protection

Always test a small area first and follow safety guidelines.

Why do some graffiti stains come back after cleaning?

This is usually due to deep pigment penetration.

If the stain:

• Was not fully extracted
• Didn’t have enough dwell time
• Was only pressure washed

…it can reappear as it dries.

FeltPen solves this by pulling pigments out instead of just washing them away.

What temperatures can it be used in?

• Works in both warm and cold conditions
• Slower reaction below ~50°F
• Faster drying in heat (keep surface damp)

Cold weather may require longer dwell times.

What are common mistakes when using FeltPen?

Avoid these:

• Not using a primary remover first (for heavy graffiti)
• Letting the product dry out too quickly
• Not applying enough product
• Rushing the dwell time

Patience is key—deep stains take time to extract.

Is FeltPen better than standard graffiti removers?

For ink, dye, and shadow removal—yes.

Most removers:

• Remove surface paint
• Leave behind staining

FeltPen is specifically designed to:

• Remove what others leave behind
• Finish the job completely

How do Bare Brick and FeltPen work together?

They are designed as a 2-step system:

• Bare Brick: Removes bulk spray paint and graffiti
• FeltPen: Removes leftover shadows, dyes, and stains

Using both gives a professional, fully restored finish.
