Our company recently purchased a new set of aluminum forms for use in constructing residential poured wall basements. Please recommend a product and procedure for seasoning our new forms.

All new unseasoned aluminum forms must be seasoned prior to the first use. Before seasoning a new set of aluminum forms, all traces of mill oil must first be removed. To remove, spray a solution of trisodium phosphate (TSP) detergent and water on the form surfaces to be seasoned, scrub with a stiff bristle brush and rinse with water.

A uniform coat of Nox-Crete’s Seasonox should then be applied to the form surfaces. After 20-30 minutes, the form surfaces should be gently rinsed with water to remove any unreacted Seasonox . Prior to use, the forms should be treated with Nox-Crete’s Form Clean and used as the release agent for the first 3-4 pours. After this, Alumi-Con or Alumi-Nox chemically active aluminum form release agents can be used. Note: For cold rolled aluminum forms, apply Seasonox EXT and allow the product to work on the surface for 48 hours before pouring.
