Aloha, I need to know the steps to take in preparing a house for exterior painting. (This is a very old house)

This is what I did, step by step:

1)Sprayed house with Clorox and water to remove mildew. Rinsed and let dry.
2)Patched holes and sand the house.
3)Now here is where my boyfriend and I buck heads. I would think to prime the whole house, and then paint. But, he says we don’t have to. Just wasting money on primer. So, he’s priming only the wood that had to be replaced.

Please advise me asap before I go bonkers! Oh, and one more thing: he’s priming in all different angles; like up and down, next section side to side. And it looks terrible! Will this show under the paint job? I thought, priming should be painted on just as your paint should be. Please help me, he won’t listen to a word I say. I might be wrong, but please clear the air so this house can be painted by the holidays.

The amount of priming you do depends on the overall condition of the wood and the paint. Also the type of paint currently on the house could affect the amount of priming. All repaired and sanded areas need priming. If the paint is in good shape then it does not need priming. But, if your home is painted with an oil base paint and you want to use a latex/arylic then the whole house needs priming.

It is difficult to know what is too much. It's my opinion that when in doubt prime it. The cost of primer is very cheap if you find yourself repainting in a couple of years.

You are correct that the primer needs to be applied is a similar manner as the paint. The different brushing directions could show when painted. I recommend rolling the primer and using a brush for the hard to reach areas.

It sounds like you are well on your way to getting ready for painting. I like the idea of starting with a clean surface and your washing has done that. Sanding is also a good idea. If a lot of sanding was necessary then priming the whole house is a good idea.
