Hello Everyone,

I'm new to this forum, and I'm looking for some input. I'm trying to "dial" in a limewash recipe. The problem that has arisen is chalking. Not, as in completely coming off the wall, but very subtle. I'm trying to keep the recipe simple,economical, & "green" as possible.
So I've allowed 5 lbs. hydrated type "S" lime stand in 1gal. h2o for a day. Then mixed hydrated type "S" lime powder with 1.5 lbs. dissolved salt & 2 qts. h2o. Been actuallly overall pleased with results.
However, the chalking is a concern. As I'm an interior natural clay plasterer, and want to keep chalking to a minimal. The product I use, is compatiable with limewashing. Only thing I've heard is possibly adding potash alum to mix. Any other suggestions would greatly be appreciated. Thanks everybody. Ck
