Replacing doors and windows often means the new trim doesn’t cover all or part of the old, and where the old trim was cut free the texture is often so difficult to touch up that it rarely comes out well.
A few days ago that happened at work, with the painters ready to spray the walls the next day and it was the end of the day, so no time for a coat of mud to even out the area as with a typical texture repair.
The old caulking was carefully scraped from the wall leaving a jagged depression about 1/4″ wide extending from the base to level with the top of the new casing. Then using a small artist brush I brushed on taping mud in small dabs mimicing as best I could the surrounding moderate orange peel texture. With the extremely fine bristles of the artist brush, some smoothing is possible of very small areas when needed, especially with a little thinned down mud or water.
The process was continued down the wall with the intent of providing a level base for the new texture. Paying close attention to anything that showed the verticle line, the high and low points started to fade from view.
Next a water based texture in a can was applied over the brushed on wet mud. The next morning everyone from our sheetrock guy to the painter were amazed that the line disapeared. In all honesty I was amazed as well.
Hope this helps someone on those annoying verticle lines.
Cheers,
Don
