Surface/styling

The proper surface preparation is essential for a successful application .For concrete surfaces applications, remove all deteriorated and loose concrete, form release agents, oil, grease, laitance, dust, dirt and efflorescence by dry or wet sandblast, shot blast, or high-pressure water .Repair deeper areas using isoflex recommended material. For steel surface should be sand blasted to commercial grade.

Mixing:

Mix both components in a clean container as per specified ratio until a homogenous mixture obtained .It is very essential that both components are thoroughly mixed .Keep still for 5 to 7 minutes induction time to allow bubbles burst prior to application.

Application

Can be applied conventionally by brush or roller and air less spray (.Nozzle Orifice 0.38 – 0.46 mm. Nozzle Pressure 1138 - 1710 psi. Dilution 0 - 5% Thinner #135) It is recommended to apply several coats instead of one thick coat to prevent entrapments of bubbles.

Safety Precautions: isocoalta in its liquid state is harmful if swallowed. Keep uncured epoxy materials away from the mouth, food or drink.
