How To Paint Anything Outside

Painting Wood Siding and Trim

Paint flaking wood.

Whether it’s lap siding, board and battens, or porch railings, if you want a successful paint job, it all starts with preparation. As is often the case with wood surfaces that have to deal with Mother Nature, the old paint begins to flake, exposing raw wood. Before you pick up your paintbrush, you need to remove as much of the old, flaking paint as possible with a paint scraper.

If you have a large area in need of scraping, you’re best bet is to use a drill motor or cordless drill with an attachment specifically designed for stripping paint. A synthetic fiber wheel does a great job and lasts much longer than the old sandpaper wheels that are often used.

For very stubborn spots, you could also apply a chemical paint stripper. This, however, will mean that the job is going to take you longer to complete because the surface needs to be completely dry before moving on to the next step. Once the loose paint is removed, prime the raw wood with a good quality primer before applying a finished coat of paint.

  1. We are almost done with the prep work for painting the outside of our home. My question is, what if the weather turns bad and we can only get the primer on. We live in north Idaho. Will we need have to put primer on again in the Spring? Our home was built in 1920 and has never had any of the paint removed, just layer after layer of paint. Thanks for any help you can give me.

  2. I am hiring a contractor to install a custom wrought iron metal fence at my house in Minneapolis. We want to paint it black.

    I am hearing different stories about whether to galvanize the iron before painting.

    Any advise out there on whether to galvanize?

  3. What is the best way to prep masonite for repainting? The original white paint is now shows dark areas possible mildew.

    Awaiting your reply.

  4. Jacqui,
    It is best to paint over primer within 30 days of application. After that it might begin to chaulk and the top coat will not adhere to it as well. Perhaps you could prime and paint part of the house before winter rather than priming it all.

  5. J. Wargacki,
    Be sure to remove any mildew first using a bleach and water solution. If the mildew/mold has gotten underneath the painted surface, you have a bigger problem on your hands, and you might have to replace it.

  6. I have a mobile home that needs painting.what kind of paint should I use should I prime first should I roll it on or spray if I spray paint it paint goes everywhere.

  7. We would like to paint the outside wood fascia board of our house at the end of November when my brother comes to help me. Can we paint when the weather is between 40 to 60 degrees?? I have been told that the paint will flake if it is applied when it’s too cold.

  8. We would like to repaint our concrete porch, it has been painted and the paint chipped, then outdoor carpet glued on it and we eventually pulled it up. I would like to make it look like it has flat rocks with grout in between, how would I start and what products would I need.

  9. We want to paint a logo on the outside wall of a cinder-block concession stand. What kind of paint would we need? Thanks

  11. Hi Danny:

    Concerning painting metal roof vents: Is it better to paint over bare galvanized metal as above or paint over one of the manufacturers colors to achieve your specific color?

    For instance: Paint terra cotta color over dark brown O’Hagin composistion roof vent.

  12. To Whom it may concern,
    I am in the process of trying to strip a metal roof in preparation to repaint it.
    The porch roof has several layers of old roof paint which has flaked off in sections, and areas which are still solid. I do not want to just paint over the old, because of the uneven holes which will make the roof uneven.
    I have tried several strippers combined with scraping such as “clean strip” the task is daunting and I have already committed many hours. I seem to be getting no where.
    I have tried a grinder with a sanding attachment, a paint stripping hand tool, to little effect.
    I really want to prep this roof properly and make the surface even when painted.
    Any tricks or guidance?,
    Thank You in advance,
    Frustrated in New Castle,
    Tom

  13. What other paint can I use on plastic. I have lots of large plastic pots which would take more paint. I have a spray gun and would like to use it and will be able to cover more with the gun.
    Thanks

  14. 10-2-09, Hello! I would like to paint an outdoor plastic Nativity figure. It is the kind of Nativity Set where each figure is lighted with a light bulb inside. What type of paint would you recommend ? I’d like to brush the paint on and not spray it. Thanks so much! Sandy Smith

  15. I would like to know the answer to the questions being asked about the outdoor lighted Navitivity figures and what type of paint to paint them!
    Thank you
    Ron

  16. I have an outdoor plastic nativity scene that needs touch up. Each peace is lighted from within. Please advise on the type of paint to use. Thank you.

  17. I too have a nativity scene with life-size plastic figures that need touch-up. What kind of paint should be used? It needs to be somewhat translucent so that the light can shine through. They appear to be made of the same plastic as milk jugs. Also, what kind of clear-coat would you recommend to keep the existing paint from chipping every time one of the figures falls over?

    Thanks,

  18. I too have an outdoor plastic nativity scene that needs touch up. Each piece is lighted from within, with a light bulb. What type of paint, other than spray paint, would you reccomend, I would like it to be durable, translucent and not melt because of the heat of the bulbs. Any suggestions would be greatly appreciated. Thank you.

  19. I have the same question as others… And also I would like to add one thing, for the Nativity scenes, what material would I use to repair wholes in areas (like the nose of the wise man). I don’t care if it is spray paint unlike the others who asked before.

  20. I am spray painting a wrought iron fense that I can’t remove. I do not want to get paint all over the house. What do you suggest I put around it to keep the paint only on the fense?

    • Hi Lori,
      I use plastic sheeting to keep spray paint off nearby objects, but avoid laying plastic on grass or shrubs, since the heat from the sun can kill it. Old sheets or blankets also work well. Good luck with your project!

  21. In regards to all the Nativity questions about paint. You can repaint them. Use 3M Easy Stripper to take remaining paint off, mask area’s off for painting using green automotive tape and you can use the spray paints for plastic such as Krylon Fusion. Check out planetchristmas.com for a complete write-up on there. It has a complete how-to on repainting your blowmolded plastic Nativity items.

  22. I have a window in my living room. When looking out you see a fence. I would like to paint a scenic picture on it.Can I do this? If so, what do i use. Thanks, Deb.

  23. Hello I bet you get this alot but how would you tape the bricks or would you to paint with a portable sprayer (a wagner) to keep paint off the bricks.Would you have to use paper that would hong over the bricks or plastiic. Ive never done this before so just thought I would ask we have a nice but for a few things to fix about it

    • Hi Melody,
      Since painter’s tape doesn’t stick well to bricks, I would either paint carefully when using a brush, or use a paint shield for spraying. You can buy a large metal paint shield for spraying at painting stores, or make your own from a piece of sheet metal or cardboard, as we did in our video on How to Make a Homemade Paint Shield. For painting with a brush, I prefer to just be careful, or you can use a drywall knife as a paint shield. Check out our video on How to Use a Drywall Knife as a Paint Shield to find out more. Good luck with your project!

  24. Hello,
    I have wood trim on our house that is just awful. I would like to paint certain areas to make it look like wrought iron, without the rust. I know there is a spray paint Rustoleum makes, but the areas are rather large. Is there any paint that comes in a bucket I can use for exterior wood trim to give the appearance of unrusted wrought iron? Thanks for your help.

  25. I have an old plastic santa that has faided over the years and I would like to give it a freash coat of paint. is there any brush on paint I could use? I’m just thinking spraying it might difficult because it is detailed with many different colors.

  26. I have a white baby jesus from a 4 foot nativity. Someone stole my original one the day after I put it out and I was able to get it but not in color. How can I paint it and what type of paint should I buy. i have someone that is willing to paint it but I need the right type of paint so it will hold up in the weather as it is for the yard. Can you please tell me what I can buy for them to paint it and what color would you suggest for the eyes as they are shut as he is asleep. Thank you for your suggestions.

  27. I have 6 different garden gnomes, all plastic and expensive. Weather has taken it’s toll on them and I am looking to hand paint them. Any suggestions on what paints I should use to refresh the gnomes and keep them looking that way for a few more years?

  28. Painting natitive set for out doors. Thank you , on the right road with your help . Will let you no what they look like 🙂

  29. The wood siding outside of our home is old and was not maintained. I would like to paint it an off white. I believe I will need to prime then paint. The wood is dry. Do I need to oil it first and then give it time to cure before painting?

  30. I’m getting ready to paint a 104 year old train car..A Pullman, with a lot of oxidation, and some rust..I’m guessing its just iron, possibly old lead paint..But any and all tips would be greatly appreciated..Thanks so much

  31. I’m spray paining my snowmobile suspension to get rid of rust. I started with rust encapsulator. Now I need to put on the top coat of paint. Now it states that I need to apply that in 70 degree weather. What would happen if I painted while it is only mid fifties? Would it just take longer? Of would I not get the adhesion I[ need?
