The above values depend on reaching the concrete strength designated for full operation and will be affected by changes in ambient conditions, especially temperature and relative humidity. Consumption ~5–7 kg/m 2 The consumption will depend on the application method and the concrete mixture (water/cement ratio). This value does not take into account the surface profile or losses. SUPPORT QUALITY The delivered concrete must be of adequate quality and comply with local standards. A concrete settlement between 75 and 110 mm (4.33 in) will normally give the best results. The slab shall be of good quality concrete with a minimum water/cement ratio consistent with the production of a fully compacted slab. The compressive strength must be at least 25 N/mm 2 (3626 psi) . It is recommended to use superplasticizers such as Sikament® or Sika Viscocrete® to ensure the optimal quality of the concrete, and where dispersed reinforcing fibers are used, for optimal dispersion in the mix. Air-entrained concrete is not a suitable support for the application of floor hardener. APPLICATION Mechanical application – Automatic sprayer in combination with laser screed Spread Sikafloor®-1 MetalTop evenly on the freshly poured concrete immediately after leveling in a single application and in consumption of 5 - 7 kg/m 2 . Manual application Depending on the conditions, excess water is removed from the concrete surface or allowed to evaporate. Spread Sikafloor®-1 MetalTop evenly on the freshly leveled concrete in 2 stages (first stage: 3 - 4 kg/m 2 ; second stage: 2 - 3 kg/m 2 ). Recommended consumption: 5 - 7 kg/m 2 . The product is applied taking care not to create unevenness on the concrete surface. Spreading Sikafloor®-1 MetalTop powder carelessly or at a distance greater than 2 meters will reduce the consistency of the finish. Compaction The first application of the floor hardener must be worked into the concrete slab and is immediately followed by the second application of the amount of Sikafloor®-1 MetalTop. Notes:
Application time The application time for floor hardeners is conditioned by each variable that influences the pouring of the concrete and therefore can vary substantially depending on the prevailing conditions. In the case of mechanical application with automatic sprayer and laser screed, spreading can begin immediately after leveling the concrete to allow the hardener to hydrate. Compaction can begin as soon as the concrete supports the weight of the concrete chipping and finishing machine (helicopter finishing). In the case of manual application, spreading the floor hardener can be done when stepping on the fresh concrete does not leave traces deeper than 3 - 5 mm (0.118 - 0.197 in). The periodic check of the state and evolution of the concrete will determine a correct time frame for each stage or sequence of application. STRENGTHENING TREATMENT Protect and seal Sikafloor®-1 MetalTop immediately after finishing using any solvent-based curing anti-evaporation product from the Sikafloor® ProSeal range (see product data sheet for the product used). Apply in a continuous and even film using a low pressure sprayer. Spread the excess material by rolling with the stencil. Joints: After finishing operations and complete cutting of the joints, immediately clean the traces of lubricant or the resulting cement paste. Joints can be sealed with Sikaflex® PRO-3 or other suitable Sikaflex® sealant according to the requirements imposed by the floor project. CLEANING OF TOOLS Clean all application tools and equipment with water immediately after use. Hardened material can only be removed mechanically. |
