SUBSTRATE PREPARATION
Concrete substrates must be sound and of sufficient compressive strength (minimum 25 N/mm²) with a minimum pull-off strength of 1.5 N/mm².
The substrate must be clean, dry and free of all contaminants such as dirt, oil, grease, coatings, surface treatments, etc. If in doubt, apply a test area first.
Concrete substrates must be prepared mechanically using abrasive blast cleaning or grinding equipment to remove cement laitance and achieve an open textured surface.
Weak concrete must be removed and surface defects such as blowholes and voids must be fully exposed.
Repairs to the substrate, filling of blowholes/voids and surface levelling must be carried out using appropriate products from Sika® MonoTop® or SikaCor® VE MY screed.
The concrete or screed substrate has to be primed or levelled in order to achieve an even surface.
High spots must be removed by grinding.
All dust, loose and friable material must be completely removed from all surfaces before application of the product, preferably by brush and/or vacuum.
For more information, please refer to "Method Statement-Evaluation and Preparation of Concrete Surfaces for Sika's Flooring System (Doc. No. CA/006/21082018)
MIXING
Prior to mixing, stir part A mechanically. When all of part B has been added to part A, mix continuously for 1–2 minutes until a uniform mix has been achieved.
To ensure thorough mixing pour materials into another container and mix again to achieve a consistent mix.
Over mixing must be avoided to minimise air entrainment.
When adding Extender-T or Quartz Sand, mix these components with part A for ~1 minute before adding part B.
APPLICATION
Prior to application, confirm substrate moisture content, r.h. and dew point.
Primer
Apply 1 primer coat of SikaCor® VE MY using a roller and let it cure.
Scratch Coat
Rough surface need to be levelled first. Apply 1–2 layers of scratch coat by trowel to the required thickness and let it cure.
Laminate Layer
Apply the first layer of SikaCor® VE MY by roller, imbed the glass fabric. Apply the second and third layer in the same way, wet on wet. After application of the final glass fabric, de-aerate and wet out the glass fabric using a laminating or disk roller
Important Note: Ensure a min. 5 cm overlapping of the glass fabric.
Top Coat
Apply 2 coats of SikaCor® VE MY by roller.
Important Notes:
- During application a high air change rate has to be provided.
- Water, even in the smallest amount, could affect the hardening and block the curing process. Tools and equipment have to be totally dry.
- Appropriate eye protection shall be worn at all times while handling and mixing products.
- Approved respiratory protection masks (eg. Half face-piece reusable respirator 6200, respiratory protection with replaceable cartridges/filters from 3M) shall be worn at all times to protect the nose and mouth from inhaling fumes from the material.
- Safety shoes, rubber gloves and other appropriate skin protection shall be worn at all times.
CLEANING OF TOOLS
Clean all tools and application equipment with acetone immediately after use. Hardened and/or cured material can only be removed mechanically.
Attention: Acetone is a flammable liquid, please handle with care. The use of Personal Protection Equipment (PPE) is mandatory.
