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 all contaminants such as dirt, oil, grease, coatings, laitance, surface treatments and loose friable material.
SUBSTRATE PREPARATION
MECHANICAL SUBSTRATE PREPARATION
IMPORTANT
Exposing blow holes and voids
When mechanically preparing the surface, make sure to fully expose blow holes and voids.
- Remove weak cementitious substrates.
- Prepare cementitious substrates mechanically using abrasive blast cleaning or planing / 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
COATING MIXING PROCEDURE
- Mix Part A (resin) until the coloured pigment is dispersed and a uniform colour is 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.
SELF-SMOOTHING WEARING LAYER MIXING PROCEDURE
- Mix Part A (resin) until the coloured pigment is dispersed and a uniform colour is achieved.
- Add Part B (hardener) to Part A.
- While mixing Parts A + B, gradually add the required filler or aggregates.
- IMPORTANT Do not mix excessivley. Mix for a further 2 minutes until a uniform 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
Protect from moisture
After application, protect the Product from damp, condensation and direct water contact for at least 24 hours.
IMPORTANT
Seal coat adhesion
Sikafloor®-304 W, Sikafloor®-305 W, Sikafloor®-316 or Sikafloor®-2540 W will not gain sufficient adhesion to the Product without proper preparation
- Abrade the surface with a red or black Scotch Brite pad or sand paper No 120
- Clean the prepared surface by industrial vacuum prior to applying the seal coat
IMPORTANT
Blinding the primer
Blinding the primer with aggregate can allow rising vapour from within the substrate to cause blisters and other surface defects in the Product.
- Do not blind the primer with aggregate to form a mechanical key
IMPORTANT
Temporary moisture barrier
If the substrate moisture content measured with the CM-method is > 4% by weight, apply a temporary moisture barrier consisting of Sikafloor® EpoCem®.
- Contact Sika technical services for more information.
IMPORTANT
No application on rising moisture
Do not apply on substrates with rising moisture.
IMPORTANT
Ensuring consistent colour matching
For consistent colour matching, make sure the Product in each area is applied from the same control batch numbers.
IMPORTANT
Temporary heating
If temporary heating is required, do not use gas, oil, paraffin or other fossil fuel heaters. These produce large quantities of both carbon dioxide and water vapour, which may adversely affect the finish.
- For heating, use only electric powered warm air blower systems.
