Gypsum Plaster

Description
Gyproc Xpert+ is a stucco gypsum plaster made for application on almost all backgrounds, e.g. brickwork, block work or concrete, suitable for application like POP punning (over Sand & Cement Plaster), bull marks, level strips, etc. It has special additives for enhanced setting time helps in controlling the onsite wastages. It provides perfectly lined and leveled surface providing a perfectly flat surface ready for painting. 
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.
• With improved Thermal resistance properties. (Thermal Resistance R = 0.07m²K/W at 13mm thickness)
• GRIHA and Greenpro Certified. 

Application

Storage & Handling
Gyproc Xpert+ is supplied both in 25Kg & 20 Kg bags. The dimensions of the bag ensure that a well-filled appearance is presented when filled and the bags can be stacked on a pallet in a stable and wellstacked array. Bags should be stored dry, as absorption of water shortens the setting time, causes set lumps to form in the bags and may reduce the strength of the set plasterwork. No hooks or any sharp tools should be used to carry bags from one location to another

Background Preparation
Surfaces should be reasonably dry, clean and protected from the weather, and suitable for the chosen specification. 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. Plaster 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 mixed with only clean water for preparation. Mixing should be carried out in a clean tray or bucket. 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: 1.25 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 
Precautions
• Dissimilar expansion and contraction of RCC and brick / stone masonry could cause stresses and at times separation. To reduce the separation cracks, use of 145 GSM glass fiber mesh (at the junction) is recommended. • It is not suitable for use in long continuously damp or severely humid conditions
