Primer over old paint after washed and scraped?

by Palmer from Louisville, Kentucky

I am unsure of what type of paint was used last on the house. I plan to powerwash and scrape before painting. I will be using Permanizer (Porter Paint) acrylic exterior paint. Should I use a primer first even though it says self priming?

Priming is a good idea, especially if you don't know what type of paint originally was used. Be aware that "Self Priming" is over itself or same type of paint. Every manufacture recommends primer when in doubt.

At the vary least you will need to spot prime any raw areas after prepping. If your house is in bad shape and requires a lot of priming, go ahead and prime everything. With a complete prime coat you know your house won't need repainting any time soon. Skipping the priming gives you a 50-50 chance of failure.
