Do you have everything you need for your project?
Polished concrete kits contain the essentials for carrying out your project. Depending on the surface, the room, and the intended use, certain tools or maintenance products may also be helpful to ensure you can complete the job with ease.
Tools for a clean application
If you are not already equipped, these tools facilitate application and prevent marks.
The Accelerator for Concrete is a chlorine-free additive specifically designed to speed up the setting time of concrete mixtures. It enables high mechanical strength in the short term through faster hardening. This additive reduces application time, making it ideal for projects requiring rapid drying, especially in cold weather conditions. In low temperatures, it also helps freshly poured concrete resist freezing.
Harmony Liquefying Agent is a liquid additive specifically formulated to improve the fluidity and workability of concrete, mortars, and screeds without increasing their water content. By facilitating application, this high-performance plasticizer reduces the water-to-cement ratio, enhancing mechanical strength.
Our fibers are in the form of fibers, polypropylene, white, 12 mm packaged in pouch pre-measured for ease of proper dosage and proper use. The fibers are intended to replace the mesh anti-cracking, as well as to reinforce concretes, mortars and plasters. Dosing is easy : 1 dose for 1 sack of cement of 35 kg.
