Concria™ Trowel Hard – Finishing Aid and Densifier
Finish concrete and dry shake floors faster and better
Concria™ Trowel Hard is superior quality nano silica finishing aid which makes flatwork finishing easier, faster, and better. It can be used also for as a concrete densifier and hardener for existing concrete floor during grinding and polishing process. The chemical reaction produces a denser concrete surface, which reduces abrasion wear and dust formation.
Applied during floating and troweling, Trowel Hard lubricates the surface, increases cream for a better finish, slows surface drying and premature set, and eliminates the need for additional water. Because it slows moisture-loss workability time extends under adverse conditions such as wind, high heat, sun, or low humidity.
Better concrete and dry shake surface – shiny, hard and dense!
Using Concria™ Trowel Hard as a finishing aid, this nano-sized technology creates barrier which minimize water to evaporate which ultimately eliminates volume loss cracking and curling. It highly reduces the potential for efflorescence and also minimizes the potential for crazing, and other drying-related surface issues.
Using Trowel Hard during the floating it makes cement hydration more efficient, so there is more cement paste available for the finisher. Well hydrated, dense cement paste slows moisture loss during finishing and permanently improves slab performance. The surface which is treated with Trowel Hard during the casting, doesn’t need any silicate (Lithium, Sodium, Potassium) treatment later. This is huge time saver for example in the concrete polishing projects. Trowel Hard becomes a permanent part of the slab, there is nothing to remove, and curing is effectively extended, reducing water vapor transmission through the slab. Improved surface consolidation and densifying reaction result in increased surface compressive strength and durability.
FEATURES & BENEFITS:
- Helps finishing under hot, dry, sunny & windy conditions
- Harden and dustproof concrete surface
- Extend workability of slab surface to achieve best possible finish
- Does not alter the water the water to cement ratio
- Helps to receive lower RA and higher DOI number
- Easy to use, densifies “green” or existing surface
