## Questions & Answers

**Q: Can you use this to paint over exterior brick.  If so, are there directions for mixture on the package?**
A: The product is natural hydraulic line 
It is a building material which is a binder

There are no directions ever for making Lime paint also all the writing is in German

However it is very easy to make a lime wash simply add enough water to create the consistency you desire probably about three times more water than lime by volume

Also historically a small amount of Linseed Oil
Or other options to change the consistency
