Application Details Substrate Quality Mortar and concrete should be cured for 21-28 days or, it must achieve a minimum

strength requirement as per ACI 503R recommendations, where a minimum compressive strength of 20.70 Mpa and pull off strength greater than 1.20 Mpa. Verify the substrate strength (concrete, natural stone etc.). The substrate surface (all types) must be clean, dry and free from contaminants such as dirt, oil, grease, existing surface treatments and coatings etc. Steel substrates must be de-rusted to a standard equivalent to SA 2.5. The substrate must be sound and all loose particles must be removed. Substrate must be dry or mat damp and free from any standing water, ice etc.

Substrate Preparation Concrete, mortar, stone: Substrates must be sound, dry, clean and free from laitance, ice, standing water, grease, oils, old surface treatments or coatings and all loose or friable particles must be removed to achieve a laitance and contaminant free, open textured surface. Steel: Must be cleaned and prepared thoroughly to an acceptable quality standard equivalent to SA 2.5 i.e. by blastcleaning and vacuuming. Avoid dew point conditions. Surface and base plate contact area must be clean and sound. For best results, the substrate shall be dry. Remove dust, laitance, oils, grease, curing compounds, impregnations, waxes, foreign particles, coatings, and disintegrated materials by mechanical means, i.e. chipping with a chisel, blastcleaning etc. All anchor pockets or sleeves must be free of water. Apply grout immediately to prevent re-oxidizing / rust formation.

Substrate Temperature +8C min. / +40C max.

Application Temperature +8C min. / +40C max.

Material Temperature Sikadur-42 PC PLUS is recommended to be applied and mixed within a temperature range between +18C and +32C. (As per ACI 351.1R-12) Store material at temperatures of between 20C -25C (room temperature) for at least 48 hours prior to its use.

Substrate Moisture Content

4% pbw

Dew Point Beware of condensation! Substrate temperature during application must be at least 3C above dew point to avoid condensation.

Application Instructions

Mix Ratio Standard pourable consistency : Solid / liquid ;Part (A + B) : C = 1 : 8 by weight Highest flowable consistency : Solid / liquid ;Part (A + B) : C = 1 : 6.77 by weight

Mixing Time Pour all of component B into the component A container. Mix with a basket type stirrer connected to an electric mixer of low speed (300-450 rpm). Mix thoroughly until uniformly blended in colour and viscosity and avoid entraining air. Pour the

mixture into a suitable mixing vessel and slowly add component C (to keep air entrapment at a minimum). Stir for approximately 5 minutes until mortar of a homogeneous consistency is obtained. Mix only that quantity which can be used within its potlife. Note: Never mix only Component A and B without adding component C (as the exothermic reaction between A and B alone generates excess heat)

Application Methods/ Tools

Prior to application, allow the mix to stand for a short time to allow entrained air to escape. The consistency of the Sikadur-42 PC PLUS epoxy grout system requires the use of forms to contain the material on top of pile head or pile cap and around base plates. In order to prevent leakage or seepage, all of these formers must be sealed. Pour the Sikadur-42 PC PLUS mortar onto the pile cap surface or into a prepared opening (hopper) and maintain enough static pressure to achieve the desired flow. The mortar may be spread by steel trowel to the required thickness levels. Ensure that entrapped air can easily escape. Large volumes have to be poured in layers. Pour next layer as soon as the previously applied layer has hardened and started to cool. Allow the grout to harden and set prior to removal of formwork Opened containers (Comp A & B) must be closed immediately after use.

Cleaning of Tools Clean all tools and application equipment with Sika Colma Cleaner immediately after use. Hardened/cured material can only be mechanically removed. Sweep excess grout into appropriate containers for disposal before it has hardened. Dispose of in accordance with applicable local regulations.

Notes on Application / Limitations

Do not thin with solvents. Solvents will prevent proper curing and change mechanical properties. Sikadur-42 PC PLUS is a vapour barrier when cured. Cold ambient, substrate or material temperatures will influence the curing and flow characteristics of Sikadur-42 PC PLUS. Do not subject cured epoxy grout to sudden temperature changes especially during early curing stages. Protect from direct sunlight. The higher the temperature of the product the quicker the reaction time and the shorter the potlife. For large or specific grouting projects please contact Sika Technical Services Department for advice.
