Gypsum Plaster - 25kg Packaging, Off White Color, High Coverage With Smooth Finish, Zero Maintenance And High Light Reflectance

Gypsum Plaster

Introduction

Plaster is suitable for application on most internal backgrounds including brick, block and concrete. It consists essentially of gypsum hemihydrate formulated with special additives to control working and setting characteristics. It dries to provide a white, smooth and matt finish.

Features

Directly applied, single coat application
Free of shrinkage crack
High coverage of 90m 2/MT*
Very smooth finish is possible
Requires zero maintenance
Enhanced light reflectance, imparts true colour tone and gloss for paint
It is compatible with all types of paints
Available in 25kg packaging

Application Methodology

- The background to be plastered should be thoroughly brushed with broom to be free from all loose particles and dust. Wash and clean traces of mould oil.
- Recommended usage of Gyploc plaster, a high performance bonding agent to eliminate hacking.
- It is recommended to pre wet the surface before application so as to achieve more spread and higher coverage.
- Mix gypsum plaster ot water (not vice versa), use a mixing rod to mix the paste thoroughly.
- Water to plaster ratio (1 Part of Water: 1.5 Part of Plaster) 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, additional dry material should not be added, as performance properties of plaster will get altered, thus affecting workability, cohesiveness, adhesion and strength.
- Avoid using a wet brush on to the finished surface, as that would leave permanent brush marks and spoil the surface.
- A single coat should not exceed 10 to 13 mm in thickness. If at all thickness required is more than 13 mm, plaster should be applied in multiple coats.
- After complete drying (which takes usually 72 hrs depending on the thickness and weather conditions), the plain smooth leveled surface is ready for painting.

The Advantages
- No Water curing - Excellent Bonding
- Pre -mixed plaster - Ecomomical
- Lightweight - Non Combustible as per BS:476:Part 4:1970
- Total strength on drying - Thermal Resistance is R=0.07 m2K/W at 13mm Thickness
