Tips on using Latex resist

Don't use good brushes.  
Latex will eventually ruin your brushes, no matter how well you clean them.  

Don't wear nice clothes. 
Latex will also ruin your clothes.

Mix a little liquid dish soap with water.  
Before using latex, wet your brush in the soapy water to help with brushability and cleanup.  (After you're finished use the same soapy water to clean your brushes.)

Application:
Apply 1 thick coat of latex.  Thinner coats may be difficult to remove.

You may thin latex resist with a little water if necessary.

When the top surface of the latex begins to yellow, it can be removed using a needle tool to gently lift edges.  

Wear a dust mask when removing the latex.  Dried glaze particles on top of the latex will create dust.
