I bought my first home a year ago and I've recently discovered that it was painted with primer, but no regular paint over the primer.
I discovered this when I was looking through some paint tins from under the house. There's a big tin on Dulux 1Step primer/sealer/undercoat, which has been fully tinted blue. After some quick research I found that primer is only usually tinted "towards" the final colour and not usually fully tinted the final colour.
I've since used some of it for touch ups and it's definitely the exact same colour.
I think the house was "painted" with the tinted primer 2-4 years ago.
Is this the previous owner cutting corners? The house had been a rental for a decade or so before I bought it so they may have been looking to save a bit of money on an investment property. Can I get by just leaving it as is, or should I be looking to paint the house ASAP?
Any help is appreciated.
