Q. The bottom shelf of our the medicine cabinet in our bathroom is solid but rusted and the cabinet as a whole needs to be painted. There is contact paper, applied years ago, on the inside door and the back wall of the medicine cabinet. It’s smooth, intact, and not shiny. If I wash the contact paper well and let it dry, and I sand to get as much rust off the bottom shelf as I can, would it be OK to paint the whole interior of the cabinet (over the contact paper) with Rust-o-leum paint?
Q. We have a garage floor that had “vinyl” tile. We removed the tile, but there is a black adhesive on it. The person who painted my house said that BM makes a concrete paint that you can apply directly over the adhesive. Is that true? If not, how is the adhesive removed?
Q. My son just had a 6-foot cedar stockade fence put in a few weeks ago. I’m wondering whether he should apply a wood preservative to seal the cedar pickets now before the winter starts. Also, what is the best preservative to use, if necessary.
Q. This question is unusual, if not unique, because the handyman is asking the question because he is assuming others have the problem: The invasion of ants. Not 2 or 3 a day or week, but 12 or more a day, simply appearing in the kitchen and bathrooms mostly, medium sized, and quite active. How to get rid of them and stay free of ants?
Q. I am trying to find out if using [a particular] house wash causes permanent clouding of the window glass. It was used per the instructions and within days all window glass became cloudy and spotted. The spots cannot be removed. I found one of your columns that suggested using Mr. Clean Magic Eraser, then Windex. Ammonia, baking soda -- nothing has worked -- not even cerium oxide polishing powder.
Q. Can you tell me what to use on my wooden thresholds so that they won’t swell from heavy rainstorms?CAROL SCHENAA. Sure can, but I have to guess on what and where the thresholds are. There are 2 thresholds, one under an exterior door front and back. They are unfinished oak, and are exposed to weather because there is no roof over the entries. And maybe there are interior thresholds, one between each doorway, whether it has a door or not.
Q. Some of the paint in our bathroom has blistered, just in one place — the corner with the chimney behind it. (We don’t have a fireplace -- just used for the gas burner, I guess.) There are numerous places where the paint is cracked and some holes (about 1 inch diameter at the most) in the paint.
Q. Around 22 years ago, in my backyard, some friends, my children and I put in a 1/2 basketball court. The children are grown and have moved on and now I would like to use it as a patio. It has held up well, no cracks and is level but it has an overall spotty, dirty look to it. I have power washed it but the dark areas are still there.
Q. I have not seen an answer to this: I am having trouble with both my doors. We just moved in, so I have no history of the problems. We wanted to change the locks: one’s complicated, so I’d call a locksmith. But that door doesn’t stay closed if it’s not locked. And the storm door won’t close by itself. How do I know if it’s the door or the frame?
Q. I re-sided an old barn with clapboards, and applied an oil-based opaque stain, which lasted 20 years. What should I do now, after scraping and sanding?JOHN HAYES, New HampshireA. That is remarkable endurance, and it might be the fact that the finish is oil-based. Try it all over again, although any oil-based opaque stain that you can buy at a paint store may not be the same as your original coat. One thing I think helped is that you put the clapboards on rough side out.
Q. In cleaning out the attic while preparing to sell my 1939 Cape in Newton, I discovered way in the back three containers, one with water in it, (the others too far in the back for me to dare peek at) and a punky spot on a board nearby. The bottoms of some cardboard boxes in the area were damp too. The last time anyone was back that far in the attic, that I know of, was 22 years ago (1992) when skylights were installed.
Q. My current home was built in 1985 and has solid wood sliding double pane windows, made by Lousiana Pacific. The windows are no longer available and most of them have leaks allowing moisture between the panes. I know I can easily have the glass in each slider replaced (the wood in most of them is fine and can be refinished and the others restored (some have minor rot). But the bigger concern is most of them ride on plastic tracks which have broken due to becoming brittle.
