Product Description

Sika EPDM Primer is a single component, solvent based, synthetic rubber primer designed to deliver enhanced adhesion to EPDM rubber substrates prior to the application of Decothane roof waterproofing systems.

Best Uses

Sika EPDM Primer is designed as a one component primer for consistent and durable adhesion between Sika Liquid Plastics roof waterproofing systems and
EPDM.

  • Excellent adhesion to new and aged EPDM rubber
  • Fast drying and curing
  • Quick and easy application

Application

EPDM membranes must be thoroughly clean, free of grease and dry. Clean surface thoroughly and ensure substrate is well bonded. Ensure surface is free from grease and free from excessive mica. Clean appropriate to contamination at site. Usually a detergent water scrub and a thorough rinse will suffice. Where heavy or specific contamination is present please consult our technical team for for advice.

Prior to the commencement of works, adhesion / substrate compatibility trials should be carried out onto the EPDM membrane to confirm substrate suitability
and adhesion of the proposed system.

Stir thoroughly with an EPI or equivalent mixer in an electric drill until all settled pigments are dispersed and the material is consistent in colour. A minimum of 5
minutes stirring is recommended. Frequent stirring (every 15-20 minutes) is recommended. Do not thin. Thinning will affect performance. Apply one coat of Sika Liquid Plastics’ EPDM Primer to securely fixed, prepared, dry surfaces by brush or short pile roller, at a maximum spread rate of 7 square metres per litre (equivalent to a minimum quantity of 0.143 litre per square metre) and leave to dry. As advised above do not use if the ambient temperature is close to dew point as condensation will form on the wet primer affecting adhesion. If this occurs, allow the surface to dry and apply fresh primer.
