Importance of Plastering Specifications
As per the work, there are different specifications for different kinds of plastering work. If these specifications are not followed to the T, then the final work will resemble a ghost house. Also the specification guidelines help keep the new areas moisture free and basically keeps the areas in hold.
There are various specifications for plastering depending on the number of coats. The specification for a single coat will differ from that required for a three coat and so on.
For a single coat, there are specified ratios for the mixing of cement, lime and sand. The ratio depends on the amount of sand used. For example, be it for internal or external plastering, the ratio of cement to lime to sand can be 1:0:3 to 6 and then, 1:1:6 and 1:2:9.
In double coats, for the under coat ratio, the sand used has to be thrice or, four times or six times the cement used. Lime isn’t used in the process.
For the final coat in double coat plastering, the ration ranges from 1:0:3 to 6 and the other ratios are where same quantity of cement and lime are used but sand taken is 6 times. Other specification is where lime is used double the quantity of cement and sand used is around 9 times.
For a three coat plaster, ratio of cement to lime to sand ranges from 1:0:3 to 6 and even 1:1:6 for the first or base coat. For the second coat too, this ratio remains the same and there can be one more which is 1:2:9. For the final or finishing coat, the lime and sand used are in equal quantity.
It should also be noted that for double and triple coats, coarse sand is preferred for the first coat and for single coat; the fineness modulus of sand can be around 1.5. If you take sand which has lesser fineness modulus, then, the plaster will not have enough strength.
Hence, it is important to get the best skilled person for the job. Though there might be many plasterers near your neighbourhood, you should try and get the most qualified and skilled plasterer.
