EPDM
Liquid Rubber®
Application |
|||||||||||||||||||||||||||||||||
| This product is a high solids solution of EPDM Rubber. It converts from liquid to solid elastomer via a unique free radical cure mechanism which works at temperatures of 55° F and higher. The characteristic high viscosity and tackiness of Liquid Rubber requires modified application methods from those of conventional coatings. It is the shape of the surface (flat, curved, corrugated, standing seam, etc.) that will determine the methods of application to be used. | |||||||||||||||||||||||||||||||||
|
EPDM Liquid Rubber® can be applied directly on many types of substrates that have solid, stable, non-porous and uniform surfaces such as flat roofs. For most substrates, primers are not necessary. As an example, some types of substrates that can be coated with EPDM Liquid Rubber® without a primer are: |

There are two basic Methods of Application, match your roof type to one of the methods below for the most likely application procedure. |

| Airless Spray | Squeegee and Roller | ||||||||||||||||||||||||||||||||
| Standing Seam | Flat Roofs | ||||||||||||||||||||||||||||||||
| Corrugated | 5,000 sq ft & below | ||||||||||||||||||||||||||||||||
| Irregular Surfaces | |||||||||||||||||||||||||||||||||
| 5,000 sq. ft. & above | |||||||||||||||||||||||||||||||||

Applying over Non Porous Surfaces: Applying over EPDM Rubber Sheets Our EPDM Liquid Rubber® can be directly applied over EPDM Rubber Sheets with little preparation other than cleaning. It is recommended, however, that for larger and older projects you use our Surface Conditioner F9910 prior to application of our EPDM Liquid Rubber®. Surface Conditioner F9910 was formulated to promote better adhesion on EPDM Rubber Sheets when a thorough cleaning is not practical. |

|
On some materials, such as EPDM rubber sheets, some swelling may occur due to solvent absorptions after applying EPDM Liquid Rubber®. This is normal. This swelling will recover with time and heat. In 80° F or so, allow 7 to 14 days to recover. In colder temperatures, recovering will take several weeks, as much as 6 to 8 weeks in 60° F. |
