I have materials left over after finishing my lime plastering, why could this be? Or I don’t have enough materials to complete my job, why could this be?
Our calculations are based on the information you provide and work on a simple sum based on square meterages and thicknesses. These have been tried and tested over many years and have been physically tested with sample panels of a set thickness set up within frames.
We round up to the nearest bag to make sure you are not short on materials.
If quantities are based, for example, on 2x 10mm coats and the actual application has been 2x8mm coats then over a large area this can drastically affect the quantities. Gauging of lime to sand should be accurate using buckets and not ‘off the shovel’.
The mixing times and additions of water will also affect coverage rates. Using premixed products such as the St Astier range of Ecomortars timing the mixing correctly will provide as much as 20% extra coverage due to air entrained in the products.
