Achieving maximum performance with the FlexRock Fluid Reinforced Roofing System couldrequire the important additional step of applying one of our elastomeric top coats. The right topcoat will offer extra elasticity, tensile strength, and superior UV protection. Need help deciding?Our team can help you determine which one is right for you, taking into account aspects likecurrent roof condition and repair budget. Let us help you evaluate your specific roof coatingneeds, so you can get the most out of your investment!Fluid Applied Reinforcement Roofing SystemCoating and sealing a flat roof is a process of important step that requires properpreparation and addressing potential problems by using various techniques and materials.Please read our roofing coating instructions and follow important steps before starting anyproject. It is imperative to use different materials based on the roof type and the problemarea. Not all roofs are the same and not all will use the same materials.See our full line ofRecommended TopCoats and Primers atFlexRockCoatings.com

1. The owner/installer must prepare the substrate for the roof by addressing all of theconditions outlined in this document. Examine substrates to receive new roofing. Pleasedo not proceed with the FlexRock Coating installation until unsatisfactory conditionshave been corrected appropriately.2. Make sure the substrate is free of delamination and defects (holes & other openings,tears, cuts, and open or partially opened seams).If the defects are larger than 1/8”, repair before coating application.3. Clean, dry and clear surfaces must be used to apply coatings or repair, free from dust,grease, wax, or other incompatible substances to facilitate appropriate adhesion. Ifgrease, oils or heavy contaminants are present on the roof surface, remove them with amild detergent prior to final cleaning. The use of bleach mixed with water can be used toremove algae, fungi, or vegetation. Thoroughly rinse surface and allow to dry prior tocoating.4. Roof decks that are deteriorated or structurally unsound should be replaced. It isimperative that the roof substrate and decking be completely dry with no moisture.(Read other considerations in this document)G E T C O A T E DSTRONG BY NATURE • HIGH PERFORMANCE INDUSTRIAL COATING SYSTEMRoof Surface PreparationA thoroughly dry and cleaned roofis critical for a long lastingapplication.

STORAGE AND MIXING Natural Minerals, and Plant-base Oils in the PartA mix will separate over time.Safety glasses, gloves, and protective clothing must be worn at all times.Part A:1. It’s recommended that Part A be stored at room temperature. Noless than 32°F (0°C).2. The Part A bucket should be stored upside down for ease of mixingwhen used. Flip over several (minimum one day) days before use.Part B:1. It’s recommended that Part B be stored at temperatures between 75° to 105°F(24° to 41°C).2. Product must be kept free of moisture. Keep container closed because the product absorbs moisturefrom the air over time.Moisture in the product causes it to produce CO2 gas which may causepressure build-up inside a sealed container.FlexRockCoatings.com | 800.808.0414 | info@flexrockcoatings.comFLEXROCK™ROOF BASE COATING INSTRUCTIONS|Visit: FlexRockCoatings.com/resourcesBe Prepared to CoatYou will only have 30 to 40 minutes (See curing estimates chart) to apply your coatingmaterial (after Part A and Part B are mixed together) to the surfaces before thecoating material starts to harden.1.In order to begin coating, the substrate must be dry which is generally not achievablewithout having the dew point temperature being at least 5°C or 10°F below thesubstrate temperature. Application temperature should be 45°F and above.2.When you finish mixing the Part A and Part B, the pot life will be about a half hourtemperature and a 24 hour cure. 3.FLEXROCK FX-100

After curing, inspect for defects and repair asnecessary.Note: Total minimum coating System Dry Film Thickness(DFT) for theentire coating system shall be a minimum of 32 mils nominally.METAL ROOFSFlexRockCoatings.com | 800.808.0414 | info@flexrockcoatings.comFluid Applied Reinforced Roof Systems

OTHER CONSIDERATIONSTHICKENING: When a thicker product is needed to fill cracksor build up, follow small batch instructions and use any of thepre-approved thick-eners to achieve the thickness desired.Thickeners include: hemp hurd, crushed walnut shells, fumedsilica, crushed polyethylene, and powdered polystyrene.STORAGE: Ensure that stored products do not freeze. Store ina cool, dry place. Part B must be kept free of moisture. Keepthe container closed. Leave Part B open and it will absorbmoisture and create CO2 gas, which leads to pressure buildup.If possible, store part A pails upside down.SHELF LIFE: is recommended that you use all product within 1year. If product has been stored longer than 6 months, shakingcan aid in freeing settled minerals.FlexRockCoatings.com | 800.808.0414 | info@flexrockcoatings.comOur factory-direct program is straightforward and designed to save you money STRONG BY NATUREZero VOCsECO FRIENDLYECO FRIENDLYSafety glasses, gloves, and protective clothing must be worn at all times.

OTHER CONSIDERATIONSA FlexRock Coating should not be considered for:1. Surfaces prone to pedestrian traffic, decks, and frequent traffic bearing. Unless using atopcoat such as a polyaspartic.2. Surfaces that are not prepared, including but not limited to wet, dusty, oily, mildewed,heavily chalked, blistered, or otherwise structurally unsound surfaces.3. Oil-bleeding and solvent-bleeding materials. The list includes, but is not limited to,some vulcanized rubber products, tapes, failed sealants, some caulking compounds andasphaltic/mastic materials without appropriate preparation and the appropriate primer.4. Surfaces where adhesion has not been verified by testing.5. New EPDM may need a primer or surface prep.6. Any type of roof shinglesFlexRockCoatings.com | 800.808.0414 | info@flexrockcoatings.com1. **Moisture Entrapment:** When moisture is present on the roof's surface or within the substrate (the layer beneath thecoating), it can become trapped between the roofing material and the roof coating during the application process. Thistrapped moisture forms a barrier within the roofing system.2. **Heat and Expansion:** When the sun's heat or other environmental factors warm the roof, the trapped moisture begins toheat up as well. As moisture heats, it expands, creating pressure underneath the roof coating.3. **Blisters Form:** The increasing pressure from the expanding moisture seeks an escape route. This pressure forces theroof coating to separate from the substrate in the affected areas, creating pockets or bubbles known as blisters. Theseblisters can range in size and are typically visible on the surface of the roof coating.4. **Compromised Coating Integrity:** As the blisters expand and multiply, they weaken the adhesion between the roofcoating and the substrate. This compromised adhesion can lead to the roof coating separating or peeling away from the roofsurface.5. **Coating Failure:** The blisters and bubbling not only compromise the appearance of the roof but also reduce theprotective capabilities of the coating. Over time, these weakened areas may crack or rupture, allowing water to penetrate theroofing system, potentially causing leaks and further damage.In summary, trapped moisture creates blisters and bubbling in a roof coating by generating pressure as it expands due toheat, causing the coating to detach from the substrate. This compromised adhesion and structural integrity can lead to theeventual failure of the roof coating, necessitating repairs or reapplication to maintain the roof's protection and performance.Proper surface preparation, moisture testing, and adherence to manufacturer guidelines are crucial steps in preventing thisissue and ensuring the long-term success of a roof coating.Trapped moisture in a roof coating can create blisters and bubbling, ultimatelyleading to the failure of the roof coating.

OTHER CONSIDERATIONSIMPORTANT: FlexRock Coatings can only ensure product performance if the applicatorsstrictly adhere to this specification.FlexRock Coatings Management must approve any changes to specifications inwriting.5. DO NOT THIN6. Keep away from food. If rain is expected within an hour of applying theproduct at temperatures below 35°F (2°C), don’t apply it. Be sure to secure thepail and tighten the lid when transporting. Store in a cool, dry, shaded location.Ensure lid is completely sealed.ROOF COATING APPLICATIONPULL-TESTING (BEFORE APPLICATION): For best results, conduct a pull testpolyester high-performance reinforcement fabric to test the surface and toensure no contaminants are present before application.STANDARD APPLICATION: For 5 minutes, mechanically mix all of part A,making sure to scrape the sides and bottom.
