Application Steps:
Step 1 : Substrate Preparation
- Ensure the substrate is sound, clean, dry and free of all contaminants such as dirt, oil, grease, cement laitance, old sealants and poorly bonded paint coatings (which affect adhesive)
Non-porous substrates:
Aluminium, anodised aluminium, stainless steel, PVC, galvanised steel, powder coated metals or glazed tiles, slightly roughen surface with a fine abrasive pad.
Step 2 :
Pre-treat using Sika® Cleaner P or Sika® Aktivator-205 with a clean cloth. Before bonding / sealing, allow a waiting time of > 15 minutes (< 6 hours).
Step 3 :
PVC has to be cleaned and pre-treated using Sika® Primer-215 applied with a brush. Before bonding / sealing, allow a waiting time of > 15 minutes (< 8 hours).
Porous substrates:
Step 2 :
Concrete, aerated concrete and cement based renders, mortars and bricks, prime surface using Sika® Primer-3 N applied by brush.
Before bonding / sealing, allow a waiting time of > 30 minutes (< 8 hours).
Note: Primers and activators are adhesion promoters and not an alternative to improve poor preparation / cleaning of the joint surface. Primers also improve the long term adhesion performance of the sealed joint.
CLEANING OF TOOLS
Clean all tools and application equipment with Sika® Remover-208 immediately after use. Once cured, hardened material can only be removed mechanically. For cleaning skin use Sika® Cleaning Wipes-100.
