Application
Application Information
Ambient Air Temperature40-100 °F (4-38 °C). Sealant should be installed when joint is at midrange of its anticipated movement.
Application Steps
SUBSTRATE PREPARATIONThe 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 using 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 Sika® Primer 429. For non-porous surfaces contact Technical Services for proper recommendation.
