When do you use latex water-based primer and when do you use oil-based primer? What's the advantage of each?
Question:
Answers:
The latex primer is marketed to those people who don't like the messy clean-up and fumes that come with an oil-based primer. For a pro, there is no comparison. Go with the original, oil-based Kilz every time. The latex is thicker, may leave brush marks, and doesn't hold up as well over time.
BUT...
If this is just a small house-hold project, and you don't want to mess with an oil based primer...feel free to use the latex.
Good luck.
Latex primers have come a long why since they first came out. With that said, I would recommend the use of latex primer for all non-metallic surfaces that are interior surfaces not in high moisture areas. While people use latex primer for painting exterior house painting I would prefer oil.
Use Oil based primer for all exterior surfaces metal and wood. Oil adheres to metal well. On wood the oil in the primer will penetrate the wood helping to preserve the wood and create a strong bond with the primer pigment on the wood surface. This creates a moisture free barrier allowing for a good adhesive bond for paint. At this point you can use either latex or oil-based paint. Not knowing your application this is the best advise I can give you.
