We would like to apply Duro-Nox liquid floor hardener to the casting slab/floor slab of a large tilt-up distribution center project. Should we apply Duro-Nox to the floor before or after the tilt-up operation has been performed?  

Although a liquid floor hardener can be applied prior to tilt-up panel placement, it is generally recommended that the tilt-up operation be performed first. Duro-Nox can then be applied to the floor after the panels have been raised and the floors have been cleaned. The application of any liquid floor hardener prior to the application of a Silcoseal bondbreaker reduces the bondbreaker’s surface reactivity, which can reduce rain and scour resistance and result in wall panel surface dusting - or in severe cases, stuck panels.

If the hardener must be applied first, ensure the product is compatible with the tilt-up bondbreaker and special precautions are followed during the tilt-up process. Contact us for more details or a specific recommendation.
