Rust-Oleum B95 High Build Flexible Epoxy

Rust-Oleum B95 High Build Flexible Epoxy is based on two-component, modified low molecular epoxy resins and is practically solvent free. Designed for application on concrete, masonry, and hand tool prepared, blasted, primed or galvanized steel. Primarily intended for airless spray application but may also be applied by brush and roller.

Features & Benefits

  • Flexible, high build epoxy for metal and concrete
  • Excellent corrosion, wear and impact resistance
  • Resistant against humidity and moisture
  • Remains flexible to prevent cracking and peeling
  • Virtually solvent free and low odour
  • Twice as thick as regular epoxies (150μm dry)

Rust-Oleum B95 High Build Flexible Epoxy offers appropriate corrosion resistance in severe industrial and coastal exposures; high humidity and moisture conditions. Rust-Oleum B95 High Build Flexible Epoxy is, due to its flexibility, especially suitable for concrete and steel floors showing good abrasion and impact resistance; porous substrates should first be primed with Rust-Oleum 5401 Epoxy Impregnation Primer; very dense substrates, like ceramic tiles, should be primed with Rust-Oleum 3333 Super Adhesion Primer.

Rust-Oleum B95 High Build Flexible Epoxy can be applied directly on properly prepared steel or galvanized steel, on itself, on Rust-Oleum 9170 Epoxy Metal Primer, Rust-Oleum 9180 Epoxy Metal Primer or Rust-Oleum 9169 Epoxy Rust Primer. This product is also suitable for application on old, reversible coatings such as Chlorinated Rubbers, Vinyls, etc. If good U.V. and/or chemical resistance is required Rust-Oleum 9600 Rust-O-Thane Polyurethane should be applied.

Surface Preparation
Remove grease, oil and all other surface contamination by alkaline or high pressure (steam) cleaning in combination with appropriate detergents. Sand intact coatings to roughen the surface slightly. Check compatibility, especially when applied on reversible coatings, the application of a test-patch is strongly recommended. The surface must be clean and dry during application.

Concrete and masonry: New concrete or masonry should cure and dry for at least 30 days before applying the coating system. Remove laitance, any loose or unsound concrete or deteriorated coatings. Smooth concrete should be roughened. Remove curing compounds.

Steel: Remove loose rust, mill scale and deteriorated coatings by hand or power tool cleaning to St 2/3 (ISO 8501-01 : 1988). Large areas may be thorough blast-cleaned to Sa 2 (ISO 8501-01 : 1988), blast profile max. 50μm.

Directions for Use
Stir individual components thoroughly before mixing them together. Use the boxing method or use a low speed mixer.

  • Mixing ratio: base (B95): activator (9501) = 1 : 1 by volume.
  • Induction time: 15 minutes for a 10 litre. mix at 20°C.
  • Pot-life: 45 minutes for a 10 litre. mix at 20°C.
  • Dilution with at least 10% Thinner 160 extends pot-life 30 minutes.

Application & Thinning

  • Brush: 10 to 15 vol.%; Rust-Oleum Thinner 160. Use natural bristles, long hair brushes.
  • Roller: 10 to 15 vol.%; Rust-Oleum Thinner 160. Use medium nap polyamide (perlon 16-20mm.) rollers. Roller application requires 2 coats to achieve recommended d.f.t.
  • Airless spray: 5 to 15 vol.%; Rust-Oleum Thinner 160. Pneumatic and electric airless equipment. Tip size: 0.015-0.025 inch. Fluid pressure: 250 - 300 bar.

Cleanup: Use Rust-Oleum Thinner 160. Preferably use disposable brushes and/or rollers.

Application Conditions
Temperature of air, substrate and coating material between 10 and 35°C and relative humidity below 85%. The substrate temperature must be at least 3°C above dew point. Maximum dry film thickness per coat: 500μm dry, equals 505μm wet.
