E814RCP Co-Polymer Reflective White Roof Coating 

E814CP is a solar heat reflective, white colored one part elastomeric co-polymer (SEBS based) liquid rubber coating modified for excellent 500%+ elongation, tensile strength, UV resistance and exceptional weathering characteristics.

Wth a solar reflectance index (SRI) of 102 the white colored E814CP helps reduce energy costs by reflecting heat away from the roof surface.  This extremely flexible roof membrane has excellent waterproofing performance and resistance to ozone as well as low temperature flexibility.  The E814RCP is Class A Fire Rated and UL Tested and Certified.

E814RCP works on flat roofs and slightly sloped roofs that may be subject to periodic ponded or pooled water. The E814RCP works on a wide range of roof surfaces including EPDM, APP, TPO, Hypalon, BUR, Fiberglass, PVC, Polyurethane Foam, Modified Bitumen, concrete, wood and metal.  For Modified Bitumen surfaces you can get color bleed through which may require an additional coat.  Not recommended for application over tar based roofing.

For roof projects requiring a non-slip walkway as part of the roof coating system, see our E814R Co-Polymer Liquid Rubber Roof Walkway Coating.

E814RCP Reflective White Roof Paint is available in 1 gallon, 2.5 gallon, 5 gallon and 50 gallon drums (ships LTL freight only).

For roof projects requiring colors besides white, please see our E814CP Co-Polymer Roof Coating which offers 11 different colors. Coverage rate depends on surface conditions and application procedures. Normally, 1 gallon per 100 square feet of a base coat and 1 gallon per 100 square feet of a topcoat combine to achieve the recommended 32 mils wet thickness (16 mils each coat).

E814RCP participates in the CRRC (Cool Roof Rating Council) Product Rating Program which describes the radiative performance of a roofing material.  The E814RCP is listed in the CRRC Rating Program Directory  Do a search using CRRC Prod ID: 0982-0004 for specific rating details on the E814RCP (also shown on our Specifications Tab).   The CRRC is an independent organization that evaluates reflectivity capabilities of roofing products initially and 3 years after installation.  The 3- year or aged testing results provide evidence as to the quality and ingredients in the roof coating as well as how it will perform in the future.

PRIMER: None required.

TOPCOAT: None required

SRI (Solar Reflective Index 3 year aged) 102     The Solar Reflectance Index (SRI) is a measure of the Solar Reflectance and Thermal Emittance (emissivity) of materials that can be used as an indicator of how hot they are likely to become when solar radiation is incident on their surface. The lower the SRI, the hotter a material is likely to become in the sunshine.  SRI is calculated with a complex formula spelled out in ASTM E 1980 and is a scale of 1 to 100 that is a measure of a roof’s combined thermal properties. It is defined so that a standard black (reflectance 0.05, emittance 0.90) is 0 and a standard white (reflectance 0.80, emittance 0.90) is 100.

PRODUCT STORAGE: Store product in an area so as to bring the material to normal room temperature before using. Continuous storage should be between 60 and 80 degree F.  Keep from freezing.

SURFACE PREPARATION: Make certain that the substrate where the product is to be applied is clean, sound and free of all laitance, dirt, dust, oil, grease, water, dew or foreign contaminants. Power washing will be an effective preparation method for most substrates. Wire brush or abrasive blast all loose and scaling rust from metal surfaces. When topcoating EPDM or seamed roofs, make sure all seams are secure. Precautions should be exercised when coating surfaces with insulation boards such as EPS to determine that the coating will not affect the underlying insulation. When the type of insulation board is unknown, a suitable test patch can be applied to determine suitability. Surface must be dry before application.

ENVIRONMENTAL CONDITIONS:Do not apply material when temperature is below 40°F during the application time or drying period. Apply material when RH is below 90% for best results. Allow for adequate dry times between coats and before inclement weather or rain. Higher humidity or lower temperatures will slow the dry time.

APPLICATION:This product may be applied by roller, brush, or spray. Spray applications may require masking and possible erection of wind screens to prevent over-spray damage to surrounding structures, vehicles, and other property. Be sure to apply this product at the specified coverage rate or recommended mil thickness. For larger flat roof areas, when spraying is not practical, the product can be applied with a suitable serrated squeegee and then backrolled with a 3/8” nap roller tool. Too thick of an application may result in solvent entrapment or rumpling of substrates such as EPDM. Some adhesives on existing structures (used to bond the rubber sheets to the deck/structures) may degrade, or are of a poor quality and may not re-bond when the swelling has recovered. Should this occur, you may need to re-bond the sheet rubber with quality adhesives. As we have no control over the type of adhesives used on existing structures, we cannot be held responsible for such occurrences.  Apply one gallon per 100 square feet per coat (two coats recommended). Always check the previous coat for foreign contamination before recoating. First coat must be free from water and dry before second coat application. NOTE: If applying over porous substrates, such as concrete but not limited to only concrete, always apply a test patch to determine suitability concerning out-gassing, which could result in pin-holing in both the first coat and subsequent coats as well as potential blisters from the out-gassing.

For best mixing results and proper blending  recommend a Jiffy Mixer style drill mixer.

REOPEN SERVICE TIME:  Take notice of the full cure time and do not open the area to abusive use before the full characteristics of the coating is achieved. Apply when weather permits 24 hours of rain free curing.

MAINTENANCE: Provide for routine maintenance of your roof to assure years of trouble free performance. Ponded water areas without positive flow of debris to drain where the debris is left to build up and accumulate and cycle through drying cycles can eventually cause the debris to bond to the coating and restrict the natural elongation of the coating. This can cause delaminations and tearing over substrates by preventing the coating from moving (expansion and contraction) with the substrate it is applied over. Accordingly, remove debris or flush the debris to drain as routine maintenance before it can build up and affect the coating.


  • Allow material to cure (24 hours) before exposure to rain or dew.
  • Do not apply a second coat until the first coat is dry.
  • Close all sources of air intake from roof into building to prevent solvent odor transfer into building.
  • Do not use indoors. Product cures from solvent evaporation-
  • Do not apply thicker than recommended. Too thick of an application can effect insulation boards such as EPS.
  • Read the MSDS before using this product.
  • Product is not resistant to solvent exposure.
  • Too thick of an application can effect insulation boards such as EPS.
  • Physical properties are typical values and not specifications.
