Application steps

SUBSTRATE PREPARATION

The substrate must be clean, dry, frost-free, sound and free of any oils, greases or incompatible sealers, paints or coatings that may interfere with adhesion.

 
Porous substrates: Clean by mechanical methods to expose a sound surface free of contamination and laitance.

Non-porous substrates: For cleaning non-porous substrates, use ''two rag wipe'' method combined with alcohol, xylene or an approved commercial solvent. Allow solvent to evaporate prior to sealant application.

  

Priming

SikaHyflex®-150 LM is designed to obtain adhesion without the use of a primer; however, certain substrates may require a primer. Test by applying the sealant and/or primer sealant combination to confirm results and proposed application methods. In the situation where primer is needed on porous surfaces use Sikaflex® Primer-429. For non-porous surfaces, contact Sika Canada for proper recommendation.

CLEAN UP

Uncured material can be removed from equipment and tools using Sika® Urethane Cleaner and Thinner. Cured material can only be removed manually or mechanically.
