During comparison in terms of performance, application becomes one of most critical element of evaluation. Application involves many aspects of performance like time of application, ease of application, ease of adaptation to new practices etc. Lets discuss them one by one.
During plastering- one person needs to bring sand and cement on-site and has to mix it thoroughly, then the application starts. This part is much more time consuming than simply bringing bags to site and applying after mixing with water.
Sand Cleaning on Site- For sand cleaning on site, one manpower is required always during conventional method of plastering. While in case of ready mix plaster, material is already premixed. Also ready mix material’s sand grading is far superior quality then what is done manually on site which ultimately results in really compact and smooth plaster.
Application Time- In ready mix plaster, polymer content has higher adhesion tendency on the substrate than normal sand cement mix. Due to this, the high retention rate of the material is obtained in each delivery on the substrate by applicator while using a ready mix plaster. It saves time during application. Also, rebound losses are less. In general practice in the market, these rebound losses are remixed in the material which also increases the time of mixing. So ineffective, time of mixing and application are both high in case of the conventional method of plastering as compared to ready mix plaster.
Curing Time- Polymeric content of ready mix plaster provides high water retention which reduces the need for long curing periods unlike in conventional method of plastering. In a conventional method, applicators cure the plastered surface for a week-long time. In the case of ready mix plaster, the same can be achieved in 3-4 days’ time. It saves lots of time and a very valuable resource i.e. water.
Mix Quality- Ready mix plaster is a machine mixed material which ensured thorough mixing of material. In the case of manual mixing on-site in conventional plaster, it is hard to achieve quality of mixing of sand and cement equivalent to ready mix plaster.
