I went to look at a building built in 1840 today. The guy wants the 70,s render removed and re-render in sand & lime. I can get putty lime locally and have a book on using lime in buildings (Building in Lime by Stafford Holmes).
The books states for plain render finish:
1st coat: 1.5 lime to 3-4 sand
2nd coat 1.5 Lime to 1.5-2 sand this is for using Hydraulic lime.
There is a similar common stucco render mix which is:
1st coat: 2 lime to 4-5 sand
2nd coat: 2 lime to 5 sand
3rd coat 1 lime to 3 sand.
Sand to be coarse washed getting finer towards the 2nd or 3rd coat and the use of hair on the backing coats and possibly in the top coat. Allow each coat to fully cure before the next coat is applied. Any reason why I cant use glass fibre strands instead of hair?
Anyone on here familiar with external lime renders? The job is to be started about May next year.
