Exterior Painting Preparation: Top 3 Ways to Sand Exterior Paint

Painting your house exteriors is fairly easy. All you need to do is to choose right paint, select proper painting equipment, and prepare the exterior surface. The preparation of the exterior is the most important task and often encompasses most of the time and effort. If you want to get a quality paint job you must prepare your surfaces well. A good surface preparation ensures that the paint job will last long years. If you do a poor paint preparation job, you will need to paint the exterior of your house again next year.

Sanding the old paint on your exterior walls, wooden trims, and siding is the most critical job. The durabilityof the exterior paint job mostly depends on successful sanding of old paint from the surfaces.

Mentioned below are the points how you need to proceed with the sand job:

Remove All Loose Paint:

You need to take a scraper and scrape all painted surfaces in order to remove loose or flaking paint. It is vital to apply enough pressure to get rid of all loose paint from the exterior surfaces. When doing so, you need to be extra careful in not applying too much pressure so that the surface may be gouged. You can use a wide scraper for siding and a smaller scraper for trim, windows, and doors.

Use coarse Sandpaper:

It is recommended to use coarse sandpaper sand all surfaces smoothly. This would gradually remove the differences between paint and any adjacent wood that is exposed during the scraping process. You can use an orbital sand paper for larger areas if necessary. However, for trim and tight spaces, it is better to use a sanding block since that would make the thing easier. It is important to make sure that you sand off any paint that didn’t need scraping to coarsen the surface to ensure better adhesion.

Use Power Sanders:

If you find that the paint is peeling from the outside wall, you can scrape the paint manually. Similarly, you can also use power sander in order to eliminate pieces of loose paint and smooth any particular edges. If the paint is applied thickly, you may require a rough sanding disc as well. This ensures that you will get rid of any marks from the exterior surfaces.
