Through our cooperation partners, we can always connect you with reliable specialist companies who have many years of experience in processing Coolkrete products. ### Can Coolkrete products only be installed by professional installers? No, in principle, even a layperson can do it themselves. However, for larger damages and in the freezer area, professional installers have better tools, skills, and processes. ### Do I need to pretreat the concrete substrate when installing Fricon or Multikrete? No, pre-wetting or priming for our rapid-setting concrete and special concrete **is not necessary and must not be carried out.** ### Do I need to prepare the concrete substrate when installing Fricon or Multikrete? In contrast to cementitious products, milling, bush hammering or blasting of the substrate is **not necessary**, but **is helpful** in **cleaning** the substrate of foreign matter. ### Does the concrete substrate have to be dry if I use your special concrete or rapid-setting concrete? **Slight moisture** (Multikrete) and **condensation moisture** from breathing air (Fricon) on the installation surface are **not a problem**for our rapid-setting concrete and special concrete. ### Do I need any post-treatment after installing Fricon or Multikrete, like with cement-based products? **No**, post-treatment such as covering etc. does **not change the setting process**. ### Do further volume changes occur as the materials set? **No**, unlike cement-based products, the filling volume is **not** subject to shrinkage, which means there is **no shrinkage or creeping**. ### Can I influence the flowability of the special mortar? The viscosity of our special mortar can be reduced by **adding a maximum of 10% liquid component. Please never add water.** ### Do Fricon and Multikrete contain synthetic resins that need to be considered for fire protection? **No**, unlike resin-based rapid-setting mortars, **Coolkrete products have even *higher* fire protection qualities** than Portland cement-based products. ### Do Fricon and Multikrete contain acrylates whose volatile components react with food? **No**, unlike PMMA-based quick-setting mortar, Fricon and Multikrete are approved for use in food environments (**TÜV food approval**). ### Are there any health risks when using Fricon or Multikrete? **No**, unlike cement- or resin-based rapid-setting concrete or special concrete, there is **no risk of burns or allergies**. ### What influences the processing time of Fricon? **To extend** the **working time** of our special Fricon concrete, the **material** should be pre-cooled. Ideally, the **liquid containers** should be removed and stored at temperatures **around freezing, while the buckets containing the solid component should be cooled to subzero temperatures**. ### How can I quickly achieve the ideal processing time of Fricon? If there is insufficient pre-cooling time, spread the dry component briefly on the clean frozen floor over an area of ​​approx. 1 sqm in order to achieve rapid pre-cooling of our quick-setting mortar or special mortar Fricon. ### Which Fricon product should I use if the installation temperature is suitable for both quick-setting mortars? If a **longer processing period** is required, **Fricon 26** should be used; if **earlier further processing** - e.g. by surface grinding - is more important, **Fricon 45** should be used. ### What happens if the temperatures are lower than expected and no short-term curing takes place? Experience has shown that if the processing temperatures fall below the specified limits, the complete curing of our special concrete or rapid-setting concrete can take up to 24 hours. We are not aware of any other negative consequences.   ### How can I optimize the processing time of our Fricon rapid-setting mortar? Please position the mixing station as close to the installation site as possible. Immediately after the mortar is visibly mixed, you should apply it, mixing partial quantities if necessary, placing it as a team, and smoothing it. ### In what delivery forms are Coolkrete products available? All Coolkrete products are available as mortar with grain sizes below 2 mm ("Standard") and as concrete with a maximum grain size of 8 mm ("JM"). ## Make contact Do you have questions about concrete repair or would you like to order our products?
