The brand CSE characterizes a group of liquid deactivators for the production of exposed aggregate concrete surfaces, for example, to make architectural prefabricated/precast concrete panels, small precast elements and products, cast stone, cast-in place walls and pavings and "rough" constructions joints.To reach exposed aggregate concrete, the first layer of cementitious material is removed so that the aggregates become visible. To control and ease this process, the CSE® Deactivator reacts chemically upon surface contact with the fresh concrete during the hydration and stops the cement from hardening there. The fresh concrete below this surface layer hydrates and hardens like normal. Later, usually after 24 hours, the surface can be washed off, which means that the "deactivated" cementitious material is removed by water jet and the aggregates are revealed. The depth of this wash-out texture is called and specified by the exposure depth in millimeters.CSE Deactivator is available in 4 different versions and each comes in 11 different exposure depths. All versions have been developed with special features to reach perfect results when used in the two main ways of application - the "negative" application (when the CSE Deactivator is applied onto a mold surface) and the "positive" application (when the CSE Deactivator is sprayed onto a freshly poured concrete surface).The version CSE Nova has been modified to perform excellently, especially when precast/prefab concrete is produced. CSE Nova is available in 11 different exposure depth types.CSE Nova is mainly used in the negative application, also called "face down" cast, which is widely used in the precast concrete industry to produce exposed aggregate concretesurfaces. CSE Nova can also be used to create exposed aggregate surfaces even when making cast-in-place walls and floors, or for construction joints with a rough surface for good adhesion.Features & Benefits water-based film-forming after drying good mold surface bond and adhesion contains best and approved active ingredient based on CSE Deactivator technology chemically engineered formulation available in 11 different exposure depth type color-coded / pigment added made to be compatible to all mold material made for "negative" and "positive" way of use eco-friendly and non-hazardous suitable for horizontal and vertical molds good abrasion resistance during pouring/casting and vibration works with all kinds of concrete, also SCC, HPC, GRC for reliable performance, regardless of consumption rate for easy application and low consumption for fast and easy mold cleaning all architectural or functional options possible for good visibility of coat after application for spray-application option no limitations in mold material selection for fast and easy wash-out more than one exposed aggregate side possible on same element Type Size of Aggregate (in mm) Exposure Depth (in mm) Color Code CSE Mino 0-4/8 approx 0.3 Light Blue CSE 01 0-4/8 approx 0.5 Blue CSE 02 2-8 approx 1.0 Brown CSE 10 2-8 approx 1.5 Green CSE 25 4-8 approx 2.0 Yellow CSE 50 6-8/12 approx 2.5 Pink CSE 70 8-16 approx 3.0 Gray CSE 130 8-16/22 approx 4.0 White CSE 200 12-16/32 approx 5.0 Orange CSE 300 16-32 approx 6.0 Violet CSE 400 16-32/54 approx 7.0 Violet Note: All the information about the exposure depths and recommended CSE types is only a guideline. The final exposure-depth is not only controlled by the chosen type of CSE Deactivator, but also affected by many other factors, for example by the amount of cement and sand, by the type of cement (gray/white, fast setting/slow setting), from the water-cement-ratio, by the demolding period.
