Looking for info on how to strip the Behr Deck Redo/Paint off of 30 yr old deck. Attempting to low budget strip, clean, and stain the wood with minimal repairs. Behr was applied last year and is holding strong, just trying to remove because undesirable and trying to prep for a traditional cedar semitransparent wood stain/sealer.

This was after 2 hrs sanding with 36grain. Additional 5% success (paint removal).
First, tried a standard premium stripper, scrubbed, and power washed. 5% success rate.

    Hi there, I would check and see if you can rent a sandblaster in your area. If a pressure washer didn't cut that will be your next best bet besides sanding the entire deck.

    Since you already did a power wash, from there I would sand to remove the remainder.

    A half sheet sander by Milwakee or Makita goes fairly quick.It takes 1/2 sheet of sandpaper at t time (you cut a whole sheet in half to fit two spring clamps on the edges). While you are at it get some knee pads and face masks or respirator. Gives a nice finish. Ready to restain.

  • I would power wash and sand it. Let dry for a couple weeks after power washing before you paint again.

    I agree that power washing is your first, best thing to do. It will save you lots of scraping and sanding. A large rental floor sander will help smooth the surface before refinishing. If there are some stubborn spots, you could strip them out, but, odds are you won't need to. Good luck and stay safe!

    The absolute best way is to heavy power wash. Let it dry completely before sanding to avoid splintering the wood

    You will have to sand to get all that product off. I used a belt sander and a medium grit sanding belt to begin with. Do NOT use a coarse belt because it will chew up the wood badly. You may have to use a palm sander as well to get to smaller areas. I followed with a finer grit sandpaper to smooth everything out. You may not be able to get all of this product out of cracks that have developed over the years. The first time I removed some nasty deck products my deck was 30 years old as well. This is a backbreaking job!! I followed 3 days of sanding , sanding, sanding with a good power wash and a deck cleaner. I let it dry for a few days in hot sunny weather and then applied an oil based deck product that soaks into the wood rather than laying on top like paint. I will never ever use any other kind of deck product that is a paint like product.

    Power washing is the first step. Scraping off what you can second. Sanding with with power sander next.


    There is a problem with the deckover products. They are known to crack and peel within two years. Hard to remove. Many Hometalkers have used them and regret it and have mention their misfortunes in discussions. Many people had o replace deck boards and even complete decks. There are class action lawsuits against the manufacturers. Also notice they are not advertised anymore. You can do some online research and find more cons than pros. I have been advising Hometalkers not to use the products and to spread the word. Some have tried scraping and sanding with fair results.


    Lots of law firms with class action lawsuits.

    Start with a high power pressure wash. Then see what you have.

    Hello Alaric,

    Use a sanding machine to do the job. You can buy or hire them.....

    I would get a rental floor sander from Home Depot and lots of the stick on sandpapers in coarse to get that paint up. Then I have used oil-based stains like Olympia for good results and no peeling.

    Rent a sanding machine from your local big box store for one day.
