SUBSTRATE QUALITY
IMPORTANT
Incorrect treatment of cracks
The incorrect assessment and treatment of cracks may lead to a reduced service life and reflective cracking.
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.
SUBSTRATE CONDITION
Cementitious substrates must be structurally sound and of sufficient compressive strength (minimum 25 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.
Maximum slope gradient
Note: Do not apply on substrates with a slope > 1 % gradient.
SUBSTRATE PREPARATION
MECHANICAL SUBSTRATE PREPARATION
IMPORTANT
Surface defects due to voids in the substrate
Voids and blow holes in the substrate will weaken the surface and damage the covering Product if not repaired during the preparation process.
- Fully expose blow holes and voids during surface preparation to identify the required repairs.
- Remove weak cementitious substrates.
- Prepare cementitious substrates mechanically using abrasive blast cleaning, abrasive planing or scarifying equipment to remove cement laitance.
- Before applying thin layer resins, remove high spots by grinding.
- Use industrial vacuuming equipment to remove all dust, loose and friable material from the application surface before applying the Product.
- Use products from the Sikafloor®, Sikadur® and Sikagard® range of materials to level the surface or fill cracks, blow holes and voids.
Contact Sika® Technical Services for additional information on products for levelling and repairing defects.
SUBSTRATE PREPARATION OF NON-CEMENTITIOUS SUBSTRATES
For information on substrate preparation of non-cementitious substrates, contact Sika® Technical Services.
MIXING
- Mix part A until a uniform colour and mix has been achieved.
- Add Part B (hardener) to Part A.
- IMPORTANT Do not mix excessively. Mix Part A + B continuously for ~3 minutes until a uniformly coloured mix is achieved.
- To ensure thorough mixing, pour materials into another container and mix again to achieve a smooth and uniform mix.
- During the final mixing stage, scrape down the sides and bottom of the mixing container with a flat or straight edge trowel at least once to ensure complete mixing.
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.
IMPORTANT
Protect from moisture
After application, protect the Product from damp, condensation and direct water contact for at least 24 hours.
IMPORTANT
Uncured material reacts with water
Uncured material reacts with water of any kind, which leads to foaming.
- During the application, wear head and wrist bands to avoid sweat falling onto the uncured material.
IMPORTANT
No application on rising moisture
Do not apply on substrates with rising moisture.
IMPORTANT
Damaged finish due to heating with fossil fuel heaters
Fossil fuel heaters powered by gas, oil or paraffin produce large quantities of both carbon dioxide and water vapour, which may adversely affect the finish.
- For temporary heating, use only electrically powered warm air blower systems. Do not use gas, oil, paraffin or other fossil fuel heaters.
IMPORTANT
Indentations in resin due to high temperature combined with high point loading
Under certain conditions, underfloor heating or high ambient temperatures combined with high point loading may lead to indentations in the resin.
Exact colour matching
Note: For exact colour matching, ensure the Product in each area is applied from the same control batch number.
SELF-SMOOTHING WEARING LAYER
- Pour the mixed Product onto the substrate. Note The consumption is specified in Application Information.
- Apply the Product evenly over the surface with a serrated trowel.
- To achieve a smooth finish, smooth the surface with the flat side of a trowel.
- Back roll the surface in two directions at right angles with a steel spike roller.
CLEANING OF TOOLS
Clean all tools and application equipment with Sika® Thinner C immediately after use. Hardened material can only be removed mechanically.
