How to Apply Poultices to Large Areas

First of all, don’t waste too much time in applying poultices to large areas if it would be easier and cheaper to replace the material.

Here are some suggestions for applying poultices to large areas:

1. Use multiple poultices and work in sections. 
2. Make sure you are consistent with the thickness of the poultice and the amount of time it is left on the surface. This will help to ensure that the poultice works evenly and effectively across the entire area. 

TIP: If you need to apply a large amount of poultice to a large area, here is another technique you could try. The poultice can be applied using a stucco spray gun. Mix the poultice thin, and spray it on the stone. You can cover a lot of area in a very short time using this method.
