Recapping from Part II…
For every type of finished surface you have in the area, there is a specific method of repair that you can follow if one of those surfaces has been damaged.
Generally, two types of repairs that can be made. The first method is the quick fix. It involves patchwork, with a little spackling or caulking. This method is suitable, if there is no real time to do the repair properly, or quality work is not essential.
The second method of repairing a flaw in the wall involves cutting out the damaged portion of the wall or wood substrate, and replacing it with a new piece. To do this, one needs patience and a knowledge of patching methods where the surrounding surface is matched and blended to match the patched area. Having experience here will guarantee a detailed, and qualitative, repair job. Remember: It should look like no repair was ever made.
Repairing a wall painted with semi-gloss or gloss paint.
One of the most difficult repairs to complete satisfactorily relates to a wall where the surface has been painted with semi-gloss or gloss paint. Have you ever seen a wall where something under the paint is magnified and stands out for all to see?
You think,” What an eye sore.” And, you wish that you could do something about it. Usually, you don’t do anything. Common sense says “Good luck with that.” “I have no idea where to start.”
The hardest thing to do is to try and match the surrounding surface texture even if it appears to be smooth. Generally, if the surrounding area has a slightly stippled surface, the surface of your repair needs to match that as closely as possible. Then the sheen of the paint will blend in.
Here are the steps to follow in this procedure:
1. Begin by sanding smooth the damaged are, a using #220 or #400 sandpaper.
2. Use a dry mix joint compound to patch the area. Wait for it to harden. You may have to make a couple of applications to complete this step.
3. Sand in sequence in the area, with #220 and #400 sandpaper, until smooth and feather edged with surrounding wall.
4. Apply an oil-based or latex primer with a small roller cover, 3/16” or 3/8.” Make sure the paint is applied evenly over the repaired area.
5. When dry, sand with #220 or #400 sandpaper depending on how the roller stipple dried. The patched area may have a slight difference from the surrounding wall.
6. Now, take the #400 sandpaper and lightly sand an area which is at least twice the area of the original repair. This helps reduce the amount of flash from the difference in paint sheen.
7. You can now apply the finish coat by using the same sized roller cover you used when priming. This time, roll the paint out past the point where you stopped sanding. Make sure the paint is rolled out thinly along the edges. This will aid in the blending process.
8. Multiple finish coats may be need to be applied.
If everything has gone successfully and the area is now fully dry, you should be able to judge for yourself how the procedure worked. There’s a good chance that it has.
