UsageIt is designed to provide a high bonding and impact resistant base coat over:
- Expanded Polystyrene foam work (EPS)
- Decorative foam shapes
- Provides suitable base for different texture finishes
- Easy and quick to apply
- Easy to mix and store
50 lb (22.7 kg) bag
12 months from date of production if stored properly in original, unopened and undamaged sealed packaging
Store dry at 40–95 °F (4–35 °C) Protect from moisture. If damp, discard material
3 qts (2.8 L) per bag
Min.: 1/16”–1/8” (1.6–3.2 mm)
- BMI 280 Foam must cure for 72 hours before application of polymer finish coat.
- If a stucco cover coat is applied, its application should take place within 48 hours. If longer than 48 hours, a suitable bonding agent is recommended.
- In hot or dry climate conditions, lightly mist BMI 280 Foam with water to ensure proper curing.

|1/8” notched trowel||45–60 ft2|
(Coverage figures do not include allowance for surface profile and porosity or material waste)
- BMI 280 Foam should be 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 the mixture can be retempered if needed.
- Do not mix any additives with BMI 280 Foam unless recommended by the manufacturer.
- BMI 280 Foam requires the use of a mesh product (fiberglass or synthetic) over the foam substrate.
- Can be applied to foam substrate and mesh utilizing an air induced application gun or by hand trowel.
- Following EIMA guidelines, BMI 280 Foam is applied to architectural foam details, the mesh is then imbedded into the wet foam layer with a trowel and additional BMI 280 Foam mixture is applied (if necessary) to “hide” the mesh and to smooth out the BMI 280 Foam layer.
CLEANING OF TOOLS
- BMI 280 Foam is highly adhesive.
- Before material dries, tools and machinery require only water and sponge for simple cleanup.
- Spillage and overspray should be removed before BMI 280 Foam dries.
- If dry, residue will require time consuming removal.
