When the homeowner checks the outside of the house and finds that the paint looks dirty or dirty, the first thing he usually thinks of is that his home will soon need a new exterior paint job. However, in many cases, repainting the outside of the entire house is not only unnecessary, but actually harmful -- Especially if the existing paint work is only two or three years old and is still basically in good condition in most parts of the house. It may be dirty outside, just because some people (or even all) The paint is dirty and nothing makes more sense than painting it when the paint surface of a car or boat is dirty. Even if the paint starts to crack or peel off some small areas, it still doesn\'t mean that a new layer of paint is needed for the whole House; Maybe it is recommended to touch only these spots and leave the rest alone. Why? Because applying too much continuous paint coating without allowing each coating to wear is usually the basic reason for the paint failure outside the old house -- The paint is just loose from the absolute weight of the thick film built over the years. However, this does not mean that the homeowner must live in an ugly appearance; He can do what the owner does. That is, he can take a bath outside the house to restore the fresh and clean after painting. This is not as difficult or impractical as it seems, especially since a closer inspection will find that only certain parts are actually very dirty. Just as the ladder can reach all the ground areas around the outside when painting the house, the ladder can also be used to get where it needs to be cleaned. However, many climbing can be eliminated by using a long handle hose brush for car wash and exterior windows. This product is available in many hardware and department stores as well as automotive stores, which are connected to the end of the garden hose so that the water flows through the handle to the end of the brush. Some people have a built-in detergent dispenser and this type is smart for home washing work. The valve allows the distribution of washing water or ordinary flushing water. The same valve also allows to close the flow of water when needed without going back to the other end of the hose. When cleaning a large wall, the recommended method is to work from the bottom up as much as possible. The idea is that when you get to the top, the surface below will be clean and humid so the dirt will fall off easily. Allowing dirt to fall on a dry paint surface often causes dirt to soak in it and create stains that are harder to remove. In any case, always ensure that the area under the cleaned part remains moist. By tracking the sun around the house, it also helps to work in the shade and is as practical as possible. When scrubbing a section, first rinse the hose off with a lot of water and then scrub it with detergent -- Either by turning the valve that distributes the detergent, or by immersing the brush in a bucket of detergent, it is convenient for those who do not have this built-in detergent. Finally, rinse thoroughly before the detergent dries on the surface. In most homes, there is no need to scrub every inch of the wall, so deal with the obviously dirty parts first. The worst areas will be those that, at least to a certain extent, are protected from the natural clean effects of wind and rain -- For example, under the suspended eaves, under the porch roof, or under the roof gutter. For very stubborn places, you will find that it is not enough to scrub with a long handle brush; You have to use a hand-held wash brush so you can apply more pressure. You also need to use a more concentrated detergent solution in these sections ( After using standard dilu tion). For this purpose, it usually helps to keep a spray bottle that concentrates the household to clean the liquid. Use it on spots that resist the original wash, and then scrub them individually with a hand brush. Horizontal windowsills and other levels as well as entrance doors, blinds, garage doors require this close-up hand scrub, and similar areas tend to be much dirtier than the rest of the house. If some very stubborn stains even resist this scrub, try using a steel wool pad soaked with soap ( The kind of pot sold). This can make the paint lose some shine but not cause real damage and remove stains that nothing else will remove. Don\'t forget the window gauze and storm belt while scrubbing the body of the house. The easiest way to do this is to lay them flat in the driveway or on the terrace and then use a hose brush that is very long processed. If the house has a combined storm and screen window, don\'t forget to clean the window sill inside the frame -- Otherwise, dirt from there will run out and cause stripes after heavy rain. After washing the outside of the House, the owner can check where the paint actually needs contact. Look for a place where the paint is cracked, bubbling or peeled off. Each of these spots should be scraped to remove all loose material and then sanded with sandpaper to \"remove\" the edges of the remaining paint on each side. Wipe off the dust with a clean rag and then touch it with matching paint. If the bare wood is exposed, use the primer first and let it dry overnight before applying the finish coating. However, if there is still sound paint underneath, then just apply a finish coating. If the most obvious peeling or cracking around the window or door, please check the caulking around the frame before painting. Missing caulking or putty allows water to enter wood or masonry and behind the paint -- This is a common cause of blistering and peeling. These minor repairs are very important- Not only can the appearance of the paint operation be maintained for a long time, but also the service life of the entire paint operation can be extended. Ignoring a small crack or bare place will allow the water to enter and will accelerate the day when more paint is bubbling or peeling. ■ A version of this file was printed on page 82 of the New York edition on May 8, 1977 with the title: using a scrub brush Not a brush.
