Paint prep  (post #188291)

Hello

I need to paint the outside of my house.  I did it 7 years ago - it's time again.  I used BM oil base paint followed by BM exterior finish coat.  Cedar ribbed shingles -  no heavy mold - no peeling paint presently.  The house is not too high - low ranch -

How do I prep for new paint.  Do I need to power wash ?  or can I just wash the painted surface with a nylon brush and TSP or something like that. 

I rather not rent a powerwasher -  any suggestions please -  Thank You,

That's a tough surface to try and clean with a brush. You can do it but you'll never get every nook and cranny like you would with a pressure washer. By the time you're done with the brush the $50.00 it would cost you to rent a pressure washer will look real cheap. The TSP running down the brush handle all day  will just about take your fingerprints off too so make sure to wear good gloves with cuffs if you brush.

Thanks for the reply -  it wasn't the rental fee that bothered me - it was getting water up under the shingles from the pressure washer  force I want to prevent. I have strong Son's for the brush scrubbing - and the house is not very big - so hand washing isn't a difficult task for us but I don't want to waste effort if you think hand washing is ineffective and should totally be avoided    Please tell me more about pressure washing  What settings on the pressure washer do I use - what type of soap -  can you give me some tips -

 

Thanks,

Use the sprayer tip with the  BIG hole, and chemical injector to spray the walls down with bleach  or bleach and  TSP solution  first. Try to stay on the shady side of the house if possible and keep they wall wet while you work.  When you have the wall covered good go back to where you started and go over the wall carefully with the pressure washer. Work down so you don't force water under the shinges any more than is necessary. Also turn the tip so that the spray pattern covers the width of the shingle. And, most important of all, keep the tip back from the wall at least a couple of feet so it doesn't cut into the shingles. Make sure you wait 3 or 4 days after washing to start painting.
