Packaging: 110 gallon kits 

VOC Content:  0gms/1 or 0.0 lbs/gal

Pot Life:   Acrylic n/a 

Curing Time:  Depends on set time of the product. Recoat as soon as possible or not more then 1-1.5 hours after first application.  Full cure in 24 to 48 @ 70°F.  Acrylic elastomeric is humidity and temperature dependent.

1. Surface Preparation

• Clean the surface thoroughly. Remove all dirt, grease, or debris that might impair bonding. If applying over urethane foam, ensure it is fully cured.

2. Substrate Priming (1–2 Hour Window).

• Apply Optimus 7010, 6200 water-reducible epoxy, or 6010R moisture-tolerant epoxy. For optimal adhesion, let the primer cure for 1 to 2 hours before moving to the next step.

3. Mix and Pre-heat Drums

• Always thoroughly mix Part B before starting. If ambient temperatures are low, pre-heat the drums according to environmental requirements.

4. Apply Aromatic Base Coat (Fast-setting)

• Spray apply the gray Optimus 2010 base coat at a rate of 2.5 gallons per 100 sq. ft. (40 mils dry film thickness) in two separate coats. Spray the second coat at a 90-degree angle (cross-hatch pattern) to the first. Note: Gel time is 5–8 seconds; tack-free in 30 seconds.

5. Apply Acrylic Top Coat (Within 1.5 Hours)

• Spray or roll the single-component white acrylic top coat over the base coat at a thickness of 20–35 mils. To prevent adhesion loss, apply this within 1 to 1.5 hours of the base coat. If using standard roof aggregate, broadcast it to refusal immediately into the wet top coat.

Unique Characteristics: Optimus ERM contains extremely small, high strength fibers.  These “nano” type fibers are stronger than steel of the same size and add additional strength to the elastomeric system. These fibers do not detract from the overall appearance of the membrane and blend exceptionally well within the matrix of the system. 

Uses:

• Industrial roof applications

• Waterproofing parapet walls

• Sealing roof penetrations

• CMU sealing

• Sealing over exposed foam

• Sealing air ducts exterior

• Waterproofing roof walkways

Advantages – ERM:

• a true monolithic roof system

• Great cold weather stability

• high tensile strength in fabric

• excellent high elongation

• Building energy consumption reduction

• high UV resistance

• sets quickly, good ponding water resistance

• good working time 

• excellent abrasive resistance

• highly adhesive – bonds to many substrates

Preparation: 

• The roof must be clean.  All repairs must have been completed, replacement of any structural elements and sheet items, etc. shall have been completed well before the application of the ERM.  The roof should be dry and any materials containing moisture shall be replaced or vented and dried.

• The surface shall be free of any contaminants that would effect bonding, i.e., dirt, grease, peeling paint and loose or foreign materials.

• Prepare parapet by removing cap, flashings as needed for replacement.  Prepare all roof penetrations using an application of ERM and the specified fabric. Apply a base coat of product, imbed the fabric and seal using a thin top coat. Make sure that crack, separations, etc. have been repaired properly with a compatible approved product.  Check mechanical units and structures for structural soundness.  Tighten and/or repair as needed before the application begins. 

• Repaired roof sections:  apply ERM at a rate of approximately 1 gallon per 100 square feet of surface area and allow to set before proceeding with the overall application.

Exposed Concrete Surfaces: where applicable, concrete must have a minimum 28 day cure prior to application.  Remove any curing agent, form release materials, oils, wax, moisture or any material that may effect bonding.  Clean and wash to remove contaminants and maintain pH 8.0-11.0.  *Perform a Moisture Vapor Test before making the coating application on concrete.  Provide rough profile minimum 2 mils. Review ASTM D4259 Abrading Concrete and ASTM F1869 Measuring Moisture Vapor Emission.  Seal/repair all bug-holes, cracks and spalls, see Madison data sheets on 820. 

Steel ladders, steel structural elements to be coated; Near white sand blast per SSPC-SP10/NACE 2.  Welds, seams, edges, etc. grind/blast smooth and provide 2 mil profile. Wood, Fiberglass: Water-blast and dry. Fill wood and fiberglass cracks, splits, voids or holidays using a compatible filler (Madsion 820). 

Steel/metal Priming – use Optimus 7010, allow a set time of about one to two hours before coating with a top coat specified for application over metal.  Consult Madison for product information.    Do not exceed 4 to 6 hours before primer is coated.  

Note:  Always test the primer and top coat for your application and before proceeding with the application.

Moisture Vapor Reduction:  Since concrete will out-gas causing pinholes, using the CMW  vapor barrier treatment for the concrete will reduce pinholes.

Applications: Application range: 50°F to 125°F. Apply not less 5°F above dew point.   Hot surface above 125°F will accelerate set and dry time, too hot of a surface should be allowed to cool before the application begins.  Viscosity can be lowered with the addition of about 5% water into the product.

Moisture & Rain:  Check the weather before the application.  Avoid making an application if freezing weather or rain is eminent within 24 hours.  

Rate:  Apply ERM at a rate of three gallon per 100 square feet of surface area in combination with the specified fabric.  

Final finish dry mil thickness shall be not less then 24 mils, not to exceed 40 mils dry.

Note:  The surface profile of the roof will often dictate the actual amount of product needed per square (100 square feet of surface area)  Some application may use more then three gallons per square.  A simple test can be done to determine the need material for the existing roof surface profile.  Consult your applicator for this prior to ordering product.

Remember to calculate for walls, penetrations, etc.  – these areas often require more product per square then the roof area.

Airless Equipment: 

• minimum of three gallons per minute

• 3000 psi

• equipment shall be capable of pumping a product with a viscosity of 120 K.U.

• Hose 5/8 inch i.d. @ 150 linear feet of hose.

• Reverse-a-tip @ .028 - .050

Rollers:  18 inch & 9 inch contractor coating rollers, standard industrial roller,  short nap roller, about 1” nap or small hand roller with 1/8-1/4 inch nap or may be applied via a notched squeegee. 

Fabric Installation:  Imbed specified fabric on any perimeter parapet walls first.  Set fabric into wet ERM  at the full height of the wall section or  vertical surfaces extending a lap of about 12 inches on to the roof area. Immediately roll the fabric into the wet product to saturate the fabric.  Assure that the fabric is properly rolled into the wet product eliminating folds, air pockets, etc. Apply the top coat of product as soon as possible.  Lap successive applications of fabric at least 2 to 3 inches.

Roof Protrusions:  Cut specified fabric in a round shape with an “X” cut in the center to allow for the protrusion to enter through the fabric.  Apply a base coat of product, imbed the fabric using a roller or brush, smooth out and eliminate bubbles, etc.  apply a top coat as needed.

Coat #1 – 1.5 to 2 gallons per square

Coat #2 – 1 to 1.5 gallons per square

Surface coverage is profile (surface) dependent of the existing roof.

Recoat time window: 2-12 hours. Do not exceed twelve hours before recoating additional coats as needed.  If recoat window is exceeded, sand lightly to produce a profile, wipe with acetone and re-coat.  

Curing Time:   Approximately two-four hours for low foot traffic volume. Cure 5 to 8 hours for more foot traffic.  Test surface cure to be sure surface is ready before allowing access.  Cure is  dependent on environmental temperature and humidity.

If using product that is excessively warm, apply a small amount first to determine the effect of heat on the set time.

• This product is for use by professional applicators only. Wear Protective Clothing. Read MSDS before using this product. DOT/Flash Point – Non-flammable Liquid Classification, not regulated.

1. Preparation & Repairs

• Ensure the roof is completely dry. Replace or vent any moisture-laden materials. Clean off all grease, dirt, and peeling paint. Perform a Moisture Vapor Test if coating concrete (must have a 28-day cure, pH 8–11, and minimum 2 mil profile).

2. Detailing & Metal Priming

• Prepare parapets and roof penetrations by applying a base coat of ERM, embedding the specified fabric, and sealing it with a thin top coat. For steel/metal elements, sandblast to an SSPC-SP10 near-white finish with a 2 mil profile, prime with Optimus 7010, and coat within a 1 to 6-hour window.

3. Pre-Treat Repair Sections

• Apply ERM to any previously repaired or patched roof sections at a localized rate of roughly 1 gallon per 100 sq. ft. Allow these spots to set before starting the main application.

4. Perimeter Fabric Installation

• Embed the fabric on perimeter parapet walls and vertical surfaces first. Apply ERM, press the fabric into the wet product to saturate it completely (eliminating wrinkles and air pockets), and extend it 12 inches onto the flat roof area. Overlap fabric seams by 2 to 3 inches.

5. Main Body Coating (Coat #1)

• Apply the first overall coat at a rate of 1.5 to 2 gallons per 100 sq. ft. directly into the remaining main body fabric layout. If the product is setting too fast on hot surfaces, you can lower viscosity by mixing in up to 5% water.

6. Main Body Coating (Coat #2) (2-12 Hour Window)

• Apply the second coat at a rate of 1 to 1.5 gallons per 100 sq. ft. totalized to achieve a final dry thickness between 24 and 40 mils. Crucial: This must be applied within 2 to 12 hours of the first coat. If you exceed 12 hours, you must lightly sand the surface and wipe it down with acetone before coating.
