Mortar and concrete must be older than 28 days (dependent on minimum strength requirements). 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.



Surface and base plate contact area must be clean and sound. For best results, the substrate should 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. Blastcleaning metal base plates to an acceptable quality standard equivalent to SA 2.5 for maximum adhesion. Apply grout immediately to prevent re-oxidizing.

The consistency of the Sikadur®-42 HF epoxy grout system requires the use of permanent or temporary forms to contain the material around base plates, for example. In order to prevent leakage or seepage, all of these formers must be sealed. Apply polyethylene film or wax to all forms to prevent adhesion of the grout. Prepare the formwork to maintain more than 100 mm liquid head to facilitate placement. A grout box
equipped with an inclined trough attached to the form will enhance the grout flow and minimize air encapsulation.



Prior to mixing the components should be stored at 15-20°C for the previous 24 hours. Mix all of component A (Grey Resin) with all of component B (Hardener) using a slow speed drill (maximum 600 rpm) and windmill stirrer. Mix until a homogeneous and streak free mixture results.

However, we are not responsible for the colour accuracy of the device you are viewing our swatches on. These variations arise due to different computer monitors and devices (make, model and technology, as well as resolution, contrast and brightness control settings) in much the same way a scan will differ from an original image and a colour photocopy. Furthermore, coatings can exhibit variation in perceived colour depending on gloss level and application method. If you require a very specific colour match, please make your selection via actual swatches and colour boards available at our showroom.
