Cement Plaster CP-200
Description
Stucco® CP-200 is factory blended cement plaster / render for internal and external use. CP-200 provides exceptional bonding and creates a base for AAC blocks. It can be applied manually or by a suitable plastering machine.
Composition
Ordinary Portland cement, hydrated lime, processed natural mineral aggregates and special chemical additives.

Method of Application
-
Surface Prearation
- Surface must be free of dirt, oil, grease, scaling paint, releasing agents, curing agents, dust, loose particles, efflorescence or other foreign materials.
- Spray sufficient amount of clean potable water to neutralize the suction of the background.
- Allow the free water to evaporate completely before the application of the render.
- The fixing of all attachments such as pipe, electrical fittings, corner beads etc should be carried out before commencement of rendering.
- Preparation on normal concrete surface Apply rush coat for Normal concrete Surface RC-200 on the prepared concrete surface. A rough texture has to be obtained to provide a mechanical key for the subsequent coat of CP-200.
- Preparation on micro silica concrete or concrete with curing compound Apply rush coat Special for Concrete Surface RC-300 on the prepared smooth concrete, which is modified with micro silica or curing compound or any other special admixture.
- Curing Curing of rush coat with potable water is absolutely necessary, 3-4 times daily for 48 hours.
- In the event of dissimilar backgrounds At all junctions of dissimilar backgrounds, fix Expanded metal lath / fibre glass mesh (as approved by the consultant) or a groove has to be formed at the junction while the plaster is still soft.
- Application On Internal and External walls of AAC – lightweight blocks
CP-200 has to be carried out in two coats with plastering machine. The base coat (spatter dash) of the same CP-200 must be applied in a thickness of 8-10 mm to provide a surface of even suction and roughness for the adhesion of final coat. The base coat must be cured with potable water for a minimum of 48 hours with 3-4 times a day. After two days when the base coat becomes hard and dry, the final coat of CP-200 must be applied to achieve a total average thickness of 15 mm on interior and 20 mm on exterior walls. When applied with plastering machine the water is adjusted by the flow meter and mixing is carried out automatically. - Curing Moist curing for 3 days (3-4 times daily) is necessary due to the absorption of moisture as well as the evaporation of surface moisture.
- Precautions Newly installed plaster should be protected from hot, dry winds and excessive ventilation. Do not apply if raining. Protect from rain for 48 hrs after application. Hard or lumpy material must not be used. The plaster has to be allowed to dry out completely devoid of any moisture, before applying any kind of stucco finish, paint or wall paper.
- Storage CP-200 200 must be protected from moisture and direct sunlight. Store off the ground in a cool and dry place.
