System structure
* In normal conditions on cement-based substrate, no primer is required. However, for very high absorbent substrates (e.g. drywalls) or non-absorbent substrates, please contact Sika Technical Service for recommendation.
Application
Backing material
Use closed cell, polyethylene foam backing rod.

SUBSTRATE PREPARATION
The substrate must be sound, clean, dry and free of contaminants such as dirt, oil, grease, cement laitance, sealant residues and poorly bonded coatings which could affect adhesion of the primer and sealant.
The substrate must be of sufficient strength to withstand the stress induced by the sealant during movement.
- Use techniques such as wire brushing, grinding, grit blasting or other suitable mechanical methods to remove all weak substrate material.
- Repair all damaged joint edges with suitable Sika repair products.
- Remove dust, loose and friable material from all surfaces before applying the sealant.
Never apply the Product to damp or wet concrete, to asphalt, or during rain.
APPLICATION
IMPORTANT
Strictly follow installation procedures
Strictly follow installation procedures as defined in Method Statements, application manuals and working instructions which must always be adjusted to the actual site conditions.
Ambient temperature
Note: In colder temperatures, reactions happen slower, leading to longer open and curing times.
In warmer temperatures, reactions occur faster, resulting in shorter open and curing times.
To guarantee complete curing, maintain material and structure temperatures above the minimum limit at any location and any point during the curing process.
- Install the cartridge into a manual or air-operated gun.
- Fill from the bottom up to within 3 mm of the roadway.
- Where required, strike off just below surface level and remove any excess material.
CLEANING OF EQUIPMENT
Clean all tools and application equipment immediately after use with Sika® Remover-208 or Sika® Cleaning Wipes-100. Once cured, hardened material can only be removed mechanically.
