Additive Formula Concrete Additive Formulations
Waterproofing Agents. Concrete Waterproofing Agents are additives formulated to increase the concrete's electrical resistance. They can be either liquid or powdered and are often added to the mixture during manufacture. Many substances, including silicates, resins, stearates, and other compounds, may be present in the additions.1. Concrete deflocculants. These concrete additives depressurise the water, improving workability while at the same time reducing or maintaining the prescribed water-cement ratio. 2. Plasticising admixtures. These concrete additives are advanced deflocculants. They have a particularly strong deflocculant action and enable efficient 6 MOST COMMON TYPE OF ADDITIVES FOR CONCRETE

Micro Cement The complete Guide to Micro Concrete
Now, you need to apply about 1 mm of micro cement and let it dry. Lightly sand the area once it is dry, then repeat the process with another coat. Typically, micro cement should get a sealer once it is dry. A sealer will prevent any potential absorption the micro cement has, making it more waterproof.
