SUBSTRATE PREPARATION
IMPORTANT
Reduced service life due to incorrect treatment of cracks
The incorrect assessment and treatment of cracks may lead to a reduced service life and reflective cracking.
- For static cracks, ensure the width is suitable for overcoating with Sika® Ucrete® HF 100 RT.
- For dynamic cracks, ensure the movement is within the movement capacity of Sika® Ucrete® HF 100 RT.
TREATMENT OF JOINTS AND CRACKS
Construction joints and existing static surface cracks in substrate require pre-treating before full layer application. Use Sikadur® or Sikafloor® resins.
The Product can be applied on green or damp concrete with no standing water. Allow for at least 3 days for early concrete shrinkage to occur to prevent shrinkage cracks from appearing on the wearing surface.
Cementitious substrates must be structurally sound and of sufficient compressive strength (minimum 30 N/mm2) with a minimum tensile strength of 1.5 N/mm2.
Substrates must be clean, dry and free of contaminants such as dirt, oil, grease, coatings, laitance, surface treatments and loose friable material.
APPLICATION
Application must be undertaken by a fully trained and licensed Sika® Ucrete® applicator.
