• If a stucco cover coat is applied, its application should take place within 48 hours.If time is longer than 48 hours, a suitable bonding agent is recommended.
• In hot or dry climate conditions, lightly mist BMI Bond 290 with water to ensure proper curing.

Application Steps

• BMI Bond 290 is mixed only with clean, potable water in a mechanical mixer or with a drill mixer in a five gallon pail.
• Mix for a minimum of 3 minutes until a paste like consistency is achieved.
• Do not overmix, although mixture can be retempered if needed.
• Do not mix any additives with BMI Bond 290 unless recommended by manufacturer.

• BMI Bond 290 requires the use of a mesh product (fiberglass or synthetic) over the foam substrate.
• BMI Bond 290 can be applied to foam substrate and mesh utilizing an air induced application gun or by hand trowel.
• Following EIMA guidelines, BMI Bond 290 is applied to architectural foam details, the mesh is then imbedded into the wet foam layer with a trowel and additional BMI Bond 290 mixture is applied (if necessary) to “hide” the mesh and to smooth out the BMI Bond 290 layer.

• BMI Bond 290 is highly adhesive.
• Before material dries, tools and machinery require only water and sponge for simple cleanup.
• Spillage and overspray should be re-moved before BMI Bond 290 dries.
• If dry, residue will require time consuming removal.
