Endurable Concrete Hardener


When looking to choose the best hardener, one should look at the superior technology of colloidal silica over the other silicate families. The size of particle should also be considered. The smaller the particle size, the better the results as there are more reaction points and the product can travel farther into the concrete at the smaller size. Endurable Concrete Hardener is a colloidal silica with the smallest particle size available at 3 to 8 nanometers, making it the best choice for a concrete hardener.
