Limpet BD6 armouring compound is a self-setting cement for internal, external and marine use as a protective layer over calcium silicate and all mineral wool insulants. Limpet BD6 does not require heat for the setting. For external applications, Limpet BD6 requires the protection by a flexible weatherproof coating as self-setting cement are not impervious to water.

Limpet BD6 is supplied in a dry powder form in strong polythene bags containing 25 kgs. This compound can be applied by hand or by using a sprayer system. The approximate usage of clean water per 25kg bag is 15 litres. Limpet BD6 and all other finishing compounds offered by IBSL are rated “Non-Combustible” to BS 476 Part 4: 1970. They act in accordance with the fire performance requirements of Class “0” as characterised in the Building Regulations.

Application and Finishing
Surfaces to be coated can be pre-damped. Materials should be used within two hours of mixing. Capyt SS100 and Limpet BD6 are normally hand applied at 6mm thickness. Limpet BD6 is also suitable for wet spray application at 5mm thickness. Wire mesh or expanded metal reinforcement can be incorporated in the applied layer where extra integrity is required. Note that self-setting cement does not require the application of heat source to induce set. Setting time is normally 24-36 hours, final drying time depends on ambient temperature and humidity. In areas of high expansion and contraction movement joints should be included to limit panel sizes to approximately 1.8m x 1.8m; for further advice see BS 5970:1981. Note that as self-setting cement contain Portland Cement, rubber or PVC gloves should be worn by all applicators, especially during hand mixing.
