PREP COAT NCP, Non-cementitious Prep Coat, is formulated with a 100% styrene acrylic emulsion. It is a trowelapplied high performance coating for use as an optional base coat on the DuROCK PUCCS RMC and InsulROCK RMC Systems, as well as the DuROCK Exterior Finish Systems. NCP is a factory-mixed base coat that does not require the addition of water or Portland cement. NCP is normally used only as a base coat on combustible construction. However, on existing EIFS installations where it may be necessary to re-finish the system, NCP is recommended for skimming over-top of existing EIFS finish coats to level the surface prior to application of a new DuROCK Finish. NCP is a flexible and durable base coat that has greater flexibility than polymer based cement base coats, hence, it is ideal for areas where greater flexibility may be required. When used as a skim coat, it is intended to be applied very tight.
