Eternabond Eternaprime Surface Primer

For surface preparation

Eternabond EternaPrime Surface Primer is an adhesive and surface conditioner intended to aid adhesion of Eternabond MicroSealant tapes, or other non- MicroSealant tapes such as butyl tapes and other self adhesive seaming tapes. EternaPrime is also an excellent primer for use with self-adhered modified bitumen membranes. Use EternaPrime when surfaces to be bonded are very dirty (oxidised and cannot be easily cleaned), or dusty (like on a tar and gravel roof). It will prepare the surface by coalescing all loose particles into a solid platform for the Eternabond tape to adhere to. EternaPrime allows Eternabond MicroSealant tapes to be installed in temperatures as low as -20°F (-29°C). It also prepares most contaminated surfaces for tape application.

Composition
EternaPrime is based on a VOC exempt solvent with a blend of Eternabond's elastomers and resins infused into the solvent.

Surface Preparation
Surface must be clean and dry. Remove heavy accumulations of loose rust and scale, dust, talc, and dirt. Oil and grease, and other contaminants should be removed with EternaClean or a non-residue cleaner. Do not use EternaPrime on PVC roofs as reactivation of some plasticisers may occur.
