What’s the application recommendation for “stack cast” panels?

Due to job site area restrictions, it will be necessary for my company to “stack cast” panels on top of each other. Are there any precautions I should be aware of when using Silcoseal Select in a “stack cast” application?

Knowing when a sufficient amount of bondbreaker has been applied between panels to ensure clean separation can be challenging. Unlike traditional tilt-up construction, where it might be a week or longer between placing and finishing a floor/casting slab and the placement of wall panel concrete, in a stack cast tilt-up application, 2-3 wall panels are placed on top of each other within 2-3 days. Due to the lack of time for cement hydration before the placement of additional wall panel concrete, the wall panel concrete is still very porous. This makes it difficult to achieve sufficient bondbreaker holdout on the stacked panel/casting surface(s).

This results in an increased potential for stuck panels. To ensure that an adequate amount of Silcoseal Select is applied between panels, saturate the top side of the panel to receive bondbreaker with water prior to application of the bondbreaker. The water will control the absorption of Silcoseal Select into panel surfaces, providing uniform film holdout.
