When coverage is difficult to estimate, add more rather than less when doing DIY wall painting. You can always pour the leftover back into cans. For large jobs, use the bucket and a roller screen rather than a roller tray. It’s much faster to load your roller with the screen than to use a roller pan. Simply dunk the roller into the paint bucket, then roll it along the screen until it stops dripping.
The materials of the home’s facade should be considered before painting your home. When painting flat surfaces like siding or wood, you can opt for standard outdoor paint. When painting a textured surface like stucco or brick, “elastomeric” paint is a much better choice. This type of paint can stretch more than normal paint, which allows it to bridge over small gaps and crevices, painting smoothly over texture. Home Painters Centennial CO
For interior paint I prefer the semi-gloss, provides a very subtle sheen and is super easy to clean -no flaking, chipping, etc. I've painted a lot, and found that Sherwin Williams Ovation paint has been the easiest to use, and provides the best coverage. I even painted my ceilings with it and WOW! I was done it no time at all, with perfect coverage. House Painting Centennial CO
