  • Sikalastic 100 EP Primer must be used as the primer for potable water applications.
  • If Sikalastic 100 EP Primer/Sikafloor 160 is being overcoated with Sikalastic®-888 Hybrid within 24 hours of application, sand broadcasting is not required.
  • Please note for substrates containing moisture (up to 6%) we suggest substituting primer for Sikalastic Moisture Seal.
  • For adhesion to other substrates than concrete please contact Sika Technical for advice.
