The Xpert Plus Gyproc Gypsum Plaster, which we present to our clients is comprehensive of high quality and is widely acknowledged in th The story of Gypsum Plaster started thousands of years ago. The earliest example of usage of gypsum plaster is at the Tomb of Tutankhamun at the Giza Pyramids which was internally lined with gypsum plasters. Today Gyproc’s range of gypsum plaster has replaced sand and cement plaster as the preferred choice for all internal plastering with all leading builders and contractors across India. Gyproc Plasters offer a full range of specific and multi-purpose solutions for all internal plastering needs and backgrounds. Gyproc plaster products are designed to suit either hand or machine application. Their consistent performance, workability and reliability is assured, thanks to our exacting manufacturing standards, which enable plasterers to maximise productivity and cut product wastage on site. Gypsum Plaster Laveling Solution For Ceilings & Drywalls Xpert+ / Xpert Xpert is available in North Markets Saint Gobain Gyproc Xpert+ / Xpert is a stucco gypsum suitable for application like POP punning (over Sand & Cement Plaster), bull marks, level strips, etc. Its enhanced setting (10 – 12 minutes) helps in controlling the on-site wastage of the product as compared to local POP with setting time of 5-6 minutes. Saint Gobain Gyproc Xpert is ideal for Plaster of Paris (POP) punning application on sand cement plastered surface giving a perfectly levelled surface which is ready for painting. Application Areas: Saint Gobain Gyproc Xpert + / Xpert can be applied on most internal surfaces like Sand Cement plaster, Bricks, Blocks & RCC (Concrete) surfaces Gyproc Xpert is a stucco gypsum plaster made for application on al- most all backgrounds, e.g. brickwork, block work or concrete, as punning agent, creating bull marks and level strips. It consists of Gypsum Hemihy- drate formulated with special additives for enhanced working and set- ting characteristics (10 minutes). It provides perfectly lined and leveled shiny surface without the worry of wastage giving a class leading coverage. Features • Extra whiteness • Doesn’t require water curing • No shrinkage cracks • Non-combustible (when tested in accordance with BS: 476: part 4:1970), therefore a good form of thermal protection to the building structure. • Use of light weight aggregates in the plaster mix help to improve the Thermal resistance. (Thermal Resis- tance R = 0.07m²K/W at 13mm thickness) • GRIHA and Greenpro Certified Technical & Physical Parameters Dry Bulk Density 880 Kg/m3 (Max) Wet Bulk Density 1.4-1.5 g/cm3 Water To Powder Ratio 1:2 Setting Time 8-12 min Chemical Composition Calcium Sulphate Hemihydrate : CaS04. ½ H2O Drying Type Setting Identification & Packing Xpert is packed in HDPE bags.

In addition, before plastering concrete backgrounds, ensure that any mould oil or other agents present are removed from the surface. No-fines concrete does not require wetting prior to plastering. Plas- ter should not be applied onto a ‘green’ background or when any free water is visible. Clean water should be applied 5-10 minutes before plaster application to control the suction. In-situ or pre-cast concrete which are exceptionally smooth or having low suction will require pre-treatment with Gyproc Bond-It bonding agent. Mixing Gyproc Xpert is pre-mixed with aggregate and only clean water is needed for preparation. Mixing should be carried out in a clean tray or bath. Excessive mechanical mixing should be avoided. Tools and water used in mixing must be clean. Contamination from previous mixes can shorten the setting time and in turn reduce the strength of the plaster when set. Water to plaster ratio (1 part of water: 2 part of plaster by weight) should be maintained to have good cohesive workable mix. Prepare plaster mix as much as required depending upon the immediate scope of work. Once the mix has begun to set, water addition is not recommended, as performance properties of plaster will get altered, thus affecting workability, cohesiveness, adhesion properties and strength. Application Gyproc Xpert should be applied with firm pressure, built out to the required thickness, and ruled to an even surface and left as an undercoat to form a key for finish coat. A thin plaster mix is made and applied as a finish coat to provide smooth surface.
