I am trying to use General Finishes (ESPRESSO) water based stain on cypress. I tried some on a scrap piece and it looks blotchy. The stain is a semi gel stain and I have never used a gel stain before so I may be doing something wrong. I wiped it on with a rag, let it set for a minute or two then wiped it off. Is this the correct technique? if not how should I do it or should I put something on the wood first like shellac or something. Thanks for any replies!!!
