Professional Mobile Repear System
The system is a well-designed rolling work platform. Think of it as the leather technician’s office, tools, and primary workspace. Roll it on-site, plug it in to any outlet and your in business.
It’s the tech’s entire livelihood encased in a rolling kit. You will quickly become as familiar with the contents, their purpose and uses as you are familiar with driving a car. There is a purpose for all components. However, if you examined all kits in use today by experienced leather technicians, there will be no two kits exactly alike. Through experience, technicians personalize their kits, adding a “this” or a “that,” and eliminating component(s) that they don’t use.
Each kit will go through this same evolution, adding and eliminating repair products and tools. This is the starting point.
Professional Mobile Repair Workstation
The system is a well-designed working platform. It is an excellent starting point that you will adapt to your own style. There is a purpose for all components. All bottles are 8 oz unless otherwise noted.
As you can see, it’s a two-level box, made of durable plastic with wheels and a retractable handle. The box is a Craftsman product modified for the leather technician. The box currently available may not be exactly as shown as newer models may arise and older models may no longer be stocked.
Repair Chemistry System Contents -
There are two types of primers in the kit.
Aniline and Semi-Aniline and Finished Leather Primer Resin (PR-1)
PR- 1 is a water-based resin, used both to promote adhesion on problematic unfinished leathers such as stain-treated anilines, pull-ups, or oil-tans, and semi-aniline very lightly coated leather. It is also appropriate for areas of finished leather where the topical finish is worn away, seriously compromised, or pH damaged. And finally, will be used to promote adhesion on finished leather. It is a solvent-tolerant soft resin that is able to penetrate the fiber structure and provide a good base for adhesion of colors or fillers on open leather and create a solid interface for adhesion on pigmented coated leathers from furniture to automotive applications.
If you have adhesion inhibitors (body oils, silicone-based products like Armor All) on or in the leather, they should be removed before application of PR-2. Consult our technical team for advice in these circumstances.
PR -1 is a concentrate and is reduce 3:1 (3 parts alcohol or acetone to 1 part primer concentrate. So, 8 oz of primer concentrate yields 32 oz of end product primer. It’s best to keep it in concentrate form, mix as you need it to prolong shelf life.
PR -1 is the best primer of choice when using a spray application for color and top coat.
SG – 4 PIMER
This is a general-purpose cleaner/primer is used predominantly with rub-coat color application. SG – 4 is also typically the primer of choice for full refinishes when using a rub technique.
There are three types of fillers:
SOFT FILLER -
Soft, flexible, water-based filler for damage on flex panels (e.g. seat cushion). It can be force-cured (quick cured) with a heat-gun using light swipes of compound, or can be bulb-cured (slow curing) with thicker swipes. It is wet and dry sand-able.
THICK FILLER –
For filling on non-flex panels (standing panels) where flexibility is not so much an issue. Higher solid content, takes less swipes to fill damage. Resin is not as flexible as soft filler. Can be force-cured with a heat-gun using lighter swipes, or bulb-cured with heavier swipes. It is wet and dry sand-able.
HIDE HEALER –
For use on highly vulnerable leather as a way to strengthen a damaged section. It’s especially useful when repairing old cracked, and chaffed leather where the integrity of the leather is challenged. Used in conjunction with the fillers, it will provide some strength to the offended area. It’s not a panacea. If the leather is totally worn out, then there is no saving it.
FINISHES - Colors
The finishes are a blended-resin binder combined with pigment producing excellent adhesive and cohesive properties. They have a low profile and good “break” characteristics. The word break refers to the flex characteristics of the finish. There are three types of finishes.
HIGH-COVERAGE COLORS – These colors are base-match colors. They have excellent coverage due to larger pigment particulate size. The larger the pigment molecule, the better the covering power. These colors include: Yellow Oxide and Red Oxide, Black, White.
MEDIUM-COVERAGE COLORS – These colors have good coverage characteristics. They include Lemon Yellow, Violet, Orange Green, and Burgundy.
LOW-COVERAGE OR TINT COLORS – These colors are used more for shifting the hue of base-match colors, or to mix print colors for when doing mottling work. They have a lower coverage due to a smaller pigment particulate size. These colors include: Blue, Red, Lemon Yellow, and Organic Brown.
The color coatings are a water-based, pigmented resin designed for both spray and rub-on applications on a wide range of leather types. They have been engineered for maximum flexibility and extension and have good adhesive and cohesive properties. They are intended for use on most upholstery-grade leathers, including furniture and automotive applications.
The pigment-to-binder ratio in all of our color coatings is the same. However, the particulate size of each individual pigment varies, so the coverage per coat varies as well from color to color. A general rule of thumb is that as the chroma (purity or intensity) of the color increases, the pigment size diminishes, and the coverage decreases. The following table outlines the coverage of our individual colors.
14 Colors: (8 oz bottles)
· Organic Yellow
· Yellow oxide
· Red Oxide
· Primary Red
· Organic Brown
· HC Brown
· Lemon Yellow
High and medium coverage colors would be used for a base-match, and lower coverage colors would be used for tinting.
All colors are softer than the clear-coats (topcoats) due to the presence of pigment in the film and the chemical nature of the resin-based binders. Clear coats are urethanes. They offer toughness to the finish, promoting durability. Pigments are a particulate matter that interferes with the cohesion prosperities of a topcoat. As such, it is not wise to attempt a “one-pass” coloring solution to a repair by mixing an abundance of color with topcoat, as the repaired area will not wear well.
Four types provided:
These are the un-pigmented clear-coats that provide the bulk of the chemical- and wear-resistance for the surface coating. They are applied after the color-coat to provide a stronger film, and to determine the final sheen (reflective value) of the application area. The three provided in your kit are Dull, Satin and High-Gloss. These are fully compatible and can be mixed to provide the appropriate sheen for a repair.
Note: The “Dull” must be shaken and filtered at each use for best results as the dulling agents must be properly distributed within the topcoat for the best results.
Our top-coats are designed as a final coating to add chemical- and wear-resistance to areas where color-coats are used, as well as determining the final sheen (or reflective value) in the application area.
The gloss top-coat (TC-1), the dull top-coat (TC-2), and satin top-coat (TC-3) are concentrates and are reduced 1:1 with water, doubling the yield. We do this in order to maintain shelf-life longevity for our dull top-coat (TC-2). Once reduced from concentrate form, each can be combined with another to achieve any sheen.
They can be applied directly to the leather surface using a sponge or brush, but for uniform application results, an air-brush or HVLP spray system is recommended.
Any product mixture remaining can be stored and re-used but should be well-shaken and filtered prior to re-use.
Once applied, top-coats can air-dry (oxidation), or can be force-cured using a heat-gun or radiant heat source. Oxidation curing times will be dictated by ambient issues such as temperature or humidity. A typical cure time to full cure is 72 hours assuming normal household ambient values for temperature and humidity.
All top-coats are water-based and non-toxic, though proper ventilation and safety measures are recommended.
Topcoat by itself may be applied to delicate (typically unfinished) leather to offer a higher degree of stain resistance. However, always test in a non-obvious area as the topcoat may alter (darken) the color in the leather, and the feel of the leather.
Spray Grain -
Spray grain is a fairly thick, (more viscous) modification of filler. It allows you to create a texture to a repair site. The repair compounds, when applied to leather, tend to create a flat surface, which may change the natural uneven topography of the leather, especially if the leather has a pronounced grain pattern. Spray grain’s purpose is to add texture to the repaired area, altering the topography and restoring as necessary the way light reflects off the leather. If the leather is heavily grained, without this texturing step the repaired areas will have a tendency to draw the eye of an observer. So, a closely matching grain is second only to color in importance for establishing an aesthetically pleasing repair.

Leather Protector --
A cream-based leather conditioner with a resin. This product has excellent properties when used on a stand-alone basis. On finished leather that has suffered chaffing of the finish coat, SG – 50, when rubbed onto the chaffed area of the leather will lay the chaffed area down, fill in minor voids in the leather, and darken the offended area. The resin in the SG – 50 is useful for resolving surface chaffing and even light scratching. The conditioning component will introduce moisture into the leather.
It has also been used as a simple primer for finished leather that is presenting adhesion problems as a result of silicone or waxes applied through products such as Pledge or Armor All. As can be seen, SG – 50 is a versatile product with multiple applications. You can add color to SG – 50 for very light scratch repair.
RUB-COAT ADDITIVE (RCA) -
RCA can be mixed with color (60% color to 40% RCA) and used as a rub-on coloring process. This is particularly useful when the client is not interested in resolving their problem with HVLP equipment or air-brush application. Nonetheless, it can be sprayed. It provides a softer feel. It can be used in conjunction with the standard spray on procedure. However, unaltered, the RCA and color mix in its natural state tends to be glossy. For this reason, RCA based coloring system can have the sheen reduced by adding DULLER CONCENTRATE. Keep in mind when using RCA based system, there is no need to apply top coat, else you could control the sheen with the addition of a top coat applied over the color coat.
DULLER CONCENTRATE –
Used to reduce the sheen of either top coat or more appropriately and RCA based color.
Oil Extractor –
There may have accumulation of body oils in leather. They may be from an animal, (e.g. dog that lies on the furniture) or a person. If so, it is important to remove it for two reasons: 1. Body oils have a different pH than leather, as such, accelerates the fibrous breakdown of the hide, and 2. oils are an inhibitor to quality adhesion of color.
Deep Penetrating Moisturizer (Gel) -
This product is used on leather that has experienced significant drying. It is chemically engineered to penetrate the fiber structure, restoring suppleness without interfering with adhesion of any subsequent color application.
There are other products that we have available but are so rarely used that it doesn’t make sense to take up real estate inside the kit. For example, Oil Blocker. This product is intended to block the migration of oils from inside the leather which would potentially create adhesion issues. IT IS NOT TO BE USED IN REPLACE OF OIL EXTRACTOR. For application advice contact Advanced Leather Solutions, Inc. technical support team. Another example is Cross Linker. Our standard top coats provide excellent wear and chemical resistance. On occasion, based on the usage factors for the target piece, the top-coat may need an added boost of protection. This is accomplished with Cross Linker. An example might be a hotel lobby where the seating is used 24/7.
These are other chemicals and their purpose to be added to the kit from local supplier like Home Depot. As all but water are solvents, we are not permitted to ship these with a kit.
WATER – The most commonly used chemical in the kit. Water is pH neutral, often used as the first step in preparing the area to be repaired. It’s the least invasive, corrosive chemical, though it will stain unfinished veg.-tan leather. Water is useful for surface dirt removal, or to reconstitute water-borne solids (milk, coffee, juice, etc.) Water won’t harm surface finish, unless saturated for long periods, like a flood or such. However, it may stiffen unfinished leathers if used in large concentrations. It is always best to use distilled water to ensure that there are no minerals, or other chemicals in the water (e. g. hard water) that may cause swelling or stiffening of the leather.
OMS - Odorless Mineral Spirits. It’s the least aggressive of all the solvents. It is used primarily to remove adhesive residue. OMS won’t harm most finishes. It is slow to flash off, and will darken many unfinished leathers.
DEGREASER (e.g. D’Limonine) – is a mild solvent that is used on grease-based stains. Used primarily on finished leathers, as it may darken some unfinished leathers. Is fairly safe on most finishes but can be mixed with alcohols to increase chemical aggressiveness. Slow to flash off, however, mixing with alcohol will decrease flash off time.
ALCOHOL – is the primary prepping agent on repair areas. We recommend using denatured (Ethyl) alcohol, but Isopropyl and Methyl alcohols are also effective. Isopropyl alcohol (IPA) is less chemically aggressive than Methyl or denatured and will have the least darkening affect. Methyl alcohol flashes off slightly quicker than denatured, but can leave a milky haze, or streaking, on some finishes. Alcohols rarely stain unfinished leathers but can bleach them if excessive rubbing is used in application. Alcohol will soften and lift finish on all but the most chemically resistant finishes. It is usually quick to flash off. In all cases lab-grade alcohol (99%) is appropriate. Over the counter rubbing alcohol is 70% pure, therefore reducing effectiveness accordingly.
ACETONE – The most aggressive solvent for your kit. It will soften and lift all but the most chemically resistant finishes, although to varying degrees. Rarely stains unfinished leathers but can bleach them. It is very effective in neutralizing silicone treatments (Armor-All, Son-of-a-Gun) as well as Scotch-Guard type treatments on finished leathers prior to repair. Acetone is also effective in removing failed vinyl repairs, or at least feathering the edges of such repairs. Because of its inherent aggressive nature, it should be used with caution. It will flash off very quickly. Be sure to not allow it to sit on the finish for too long a period as it may coagulate the stripped finish into clumps, thereby increasing the amount of time required to strip the leather.
Application Tools and Equipment
Built-in Compressor – Professional grade, durable compressor. It is 1/3 HP compressor/vacuum pump to drive the air brushes.
Manifold – Constructed cast pipe connected to the compressor with two outlets to allow for multiple air brushes attached simultaneously. For example, color brush and top coat brush connected via quick connects.
