How far should a concrete hardener penetrate? And why does it matter?

Most concrete surface hardening products will penetrate 2-4 mm into the slab. With time and usage, there is real risk of “crust” formation. The hardened crust is so thin, that it can potentially craze or crack, or even delaminate from the rest of the slab. Where the slab is subject to heavy traffic — for example, a warehouse where forklifts operate — the risk is particularly high.

The better method is to use a penetrating hydrogel treatment. This involves a catalytic process which works its way into the porosity of the concrete. The resulting hydrogel penetrates and hardens up to 150 mm deep. The integrity and durability of the concrete are significantly enhanced.

The hydrogel remains in the concrete permanently - no re-treatment is required - and is not subject to surface damage or abrasion.

The resulting concrete surface remains hard and durable for its entire life. Additionally, the surface has anti-dusting qualities, is easy to clean, resists contaminant attack, and is ideal for line marking.

If you've tried using catalytic silicate #hydrogel for concrete hardening, I'd like to hear about your positive or negative experiences. Share a comment!
