How do I sandblast a house before painting it?

Question

I have a historic house with intricate exterior woodwork, and it hasn't been painted in 50 years.. It looks salt and peppered. I need to sandblast the house, which will be the quickest and easiest way. It would be impossible to scrape this house.

My question is, can someone help me understand what type of sandblasting equipment I need to buy to get this done? I've seen smaller sandblasting equipment at lowes and homedepot, but it would take forever. What do painters use? where can i buy something a little more heavy duty to get this process done?

Thanks!

Answer 1

Use a pressure washer. Unless the house is concrete, you will destroy the intricate details with a sandblaster. You can rent or buy pressure washers with 3000 pounds of pressure. This pressure will cut into wood if you get too close.

You can power wash or sandblast if you want, you can also wire brush the places where the paint is peeling. Once you have taken the paint down to where there is no more peeling or bubbling, apply PRIMER!!!!! The reasons your paint is not lasting are, # 1 - you haven't applied a base primer to give the top coat something to stick to. # 2 - You are painting when it's too hot or too cold.,You must always read the manufacturers directions for use, and pay attention to the proper temperature as to when to paint, somewhere between 58 deg. and 78 deg. # 3 - Always give each coat of paint , (primer or base coat) 24 hrs. to properly cure before applying a new coat. Always start with a Clean, Sound, Dry surface to paint on. Paint at the right temperature and let paint cure 24 hours before applying additional coats.

Answer 6

You really can't control a sand blaster well enough to keep from doing serious damage. The old fashioned ways are going to be the best. Heat gun and scrapper, sandpaper, scrapper and elbow grease. Some selected use of paint remover.

If you really want to try sandblasting. I suggest you use a very fine grit that some call dust blasting. You will also need to have very careful control of the air flow both volume and pressure.

a large sandblasting rig is very expensive. You might consider hiring someone who does that for a living. It would be cheaper than buying the equipment yourself. Good Luck :)

Answer 8

get a couple of gallons of bleach and a handheld weed sprayed and mix 50/50 bleach and water spay enuff to put a light mist on the area and use a pressure washer alot of the paint will come off and what is left you can use a oil base primer and paint the primer on before you repaint the house

Answer 9

Abrasive blasting is not recommended because it removes the skin coat of the material, exposing wood that has been protected by the skin coat for year and which is more fragile. If you don't have a business, don't buy. Pressure washers can be rented from industrial tool rental companies.

Answer 10

Sand blasting a house will be very expensive and may cause damage to the wood work. If you want to have the house sand blasted you will have to hire a contractor for this because the house will have to be tented during the actual sand blasting because of EPA air quality laws and regulations. A good pressure washing is the best choice followed by a wire brush and scrapper to remove anything that is left after the pressure washer is finished.
I would never recommend sand blasting unless you have an older brick home and you want to renew the brick.
