How to even dents and scrape marks over entire wall
I usually lightly sand and use standard Sheetrock mud, after it is dry I sand again if I think this looks good I then use a can of spray texture and blend some new texture with the old, after the spray texture is dry and a fresh coat of paint when we’ll done you really won’t see the repair. Never tape off an area when using spray texture that makes lines that stand out after painting (one of the best DIY repairs I have seen was spoiled because they taped off the area instead of blending.
