Method Statement for Plastering Internal and External Walls

In building construction, plastering of walls is a vital aspect for offering a great finish to the wall. Plastering usually provides a smooth finish and durable surface to both external and internal walls. At First Choice Speciality chemicals, we achieve great results over high-quality plaster finish by including ideal preparation, appropriate ratio mixing and proper execution under the supervision of experienced professionals. In this blog we will discover FCSC's expert guide or method statement on plastering internal and external walls for a durable and smooth finish.

Internal wall plastering

  • Before going into further details, our first priority is to clean the surface to ensure no existence of dirt, debris or any other loose particles. We at First Choice Speciality chemicals are highly committed to this surface cleaning by using several techniques to ensure good adhesion of the plaster on both sides of the wall.
  • After cleaning the surface, we performed two stages in which the first stage includes creating a slurry by mixing with SBR latex(CEMBOND SBR) and water in the ratio of 1:4. Once this process is done, gradually add 6-7 parts of cement to this mixture that ensures uniformity and smoothness in the mixture. While doing work, we usually prefer to use the slurry form by using a brush or Trowel for improving the bonding between plaster and wall surface.
  • Once the first coat is done, the second coat may follow the mixture of CEMBOND SBR while it becomes slightly tacky within 30 minutes. Second coat to the wall ensures the robustness and durability to the wall.
  • In the third step, your focus should prepare Cementitious Repair Mortar to achieve optimal performance and highest dispersion throughout the mixture. In doing so, you can use AQUAPROOF IW into the Cementitious Mortar mix which must be 0.1%-0.4% with water before mixing to the Mortar. In doing so, you can mainyaya low water/ cement ratio to achieve the optimal performance. Imbalance in water/ cement ratio can lower the adhesion in plaster that may hamper in durability.
  • Once the Mortar has been prepared, plaster should be allowed for 5-7 days for proper drying of the wall. Drying of plastered walls can give it strength and increase capability to work against damage. After drying the plastered wall, applying polymer modified wall putty in which you can use FCSC Wall Safe putty to get a smooth and lucrative finish to the wall.
  • We at First Choice Speciality chemicals also take care of the walls that will not be painted. In doing so, we suggest applying a protective coat of Cemocoat AR with water in the ratio of 1:4. You can use two coat as well depending upon the walls capabilities to achieve better durability.

External plaster Wall

  • Plastering the external wall, initial preparation is to clean the external surface just like the internal wall. It can be followed by the step of creating a slurry by mixing 1 part of CEMBOND SBR latex with 4 parts of water to get uniformity in that mixture. After preparing slurry , you can add 6-7 parts of cement to bring smoothness in the solution. Later, the mixture can be used on the external wall with the help of a Trowel.
  • In the second coat, we suggest to use the same slurry within 30 minutes after completion of the first coat, it becomes tacky. We at First Choice Speciality chemicals take significant care of managing appropriate ratios to ensure strong and durability in the plastered wall.
  • Finishing coating followed by Mortar preparation in which you can use FCSC prepared AQUAPROOF IW at 0.1%- 0.4% with measured quantity of water and mix it uniformly. While plastering the external side of the wall we recommend to use less water and much cement as it protects it from the rain and other complexities. Following the steps and guides, you can get maximum workability and also be able to provide strength to the wall for a longer period.
  • In this stage, we suggest leaving the plastered wall for maximum 10 days to ensure proper cure along with the durability. While drying the wall, you can use FCSC Wall Safe putty just like internal wall plastering because this product is equally effective to give a robust platform for further painting.
