COSMO CSE REACTIVE SURFACE DEACTIVATOR
Cosmo CSE® Characterises 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“Construction 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 Waterjet And The Aggregates Are Revealed. The Depth Of This Wash-Out Texture Is Called And Specified By The Exposure Depth In Millimetres. 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 Mould Surface) And The „Positive“ Application (When The CSE® Deactivator Is Sprayed Onto A Freshly Poured Concrete Surface).
