Color Render CR-101
Description
Stucco® CR-101 is dry premixed pigmented plaster that can be applied internally and externally. Being mineral based, it has water retention and breathing capacity and therefore, reduces condensation between plaster and the basic construction work. CR-101 is available in various colours and textures
Composition
White Portland Cement (High Strength 52.5 grade), processed mineral aggregates, graded fillers, U.V resistant colour pigments compatible with GCC climatic conditions and Special polymer additives for better workability , adhesion and water resistance properties.

Method of Application
- Surface preparation
- 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 gypsum plaster GP-100.
- 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 CR-101.
- Preparation on concrete with micro silica or 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.
- Mixing CR-101 when applied manually, mixing should be done in a clean non-corrosive, uncontaminated metal tub. Add 8.5 ltrs of clean potable water to 50 kg bag and mixing by an electrical agitator to ensure a homogeneous and uniform mix. When applied with plastering machine the water is adjusted by the flow meter and mixing is carried out automatically.
- Application CR -101 can be applied to a thickness of 15mm in one coat with spray machine. But where the thickness is expected to exceed more than 15mm it should be applied in multiple coats with receding thickness. In that case the previous coat of plaster must be cured for at least 2 days and final coat should always be done with the wooden trowel. Use of steel trowel should be avoided for the final finish. For external rendering it is recommended to apply in two coats.
- Curing 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.
- 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.
- Storage CR 101 must be protected from moisture and direct sunlight. Store off the ground in a cool and dry place.
