When spray painting my kitchen cupboards, how much do i need to thin my paint to spray without clogging the spraygun?
Welcome to Workshop @dswes and thanks for making your first post. I trust you will find plenty of great information and ideas on the site, plus have plenty of fun.
I haven't had a lot of experience using spray guns (I used one for the first time a few weeks ago to do my backyard fence) but I believe the answer to your question will depend on what spray gun you are using and what paint you are using. Could you please tell us a bit more about what you are planning to use so the community can provide some assistance and advice?
Definitely depends on the spray gun and the type of paint. Some paint is designed to be sprayed and you don't need to add any water.
@dswes Depending on the surface you may need to use a laminate or grip lock style primer as paint will not adhere to glossy surfaces.
