When your brush is loaded with paint, it's easy to create runs by applying too much paint in corners or along trim. To avoid that, start brushing about 1/2 inch away from the cut-in area to apply the paint. As the brush unloads, move over and slowly drag the brush along the trim or corner. Let the bristles gently push the paint against the cut-in area where the walls meet. You may have to do this a couple of times to get complete coverage, but it'll avoid excess paint along woodwork and in corners.
Whether you buy cheap or expensive roller covers, washing them before their first use gets rid of the fuzz that inevitably comes off once you start painting. Wash them with water and a little bit of liquid soap, and run your hands up and down the covers to pull off any loose fibers (a practice called "preconditioning covers"). You can start using the roller covers right away—you don't need to let them dry.
Thanks, all, for your time & efforts adding to the article & comments, especially Dave urging requesting both General Liability AND Worker Compensation insurance certificates to protect from real & fraudulent liability--from my experience especially in California, where insurance fraud is a popular income thief, even causing car collisions to collect.
Just like with roller paint application, painters are not limited to using just one stroke when cutting in. It is important, however, to work towards the edge of the corners applying even pressure. If time permits, painters should allow their cut in work to dry completely before applying paint with rollers, keeping in mind that light touchups on corners and edges will always be required at the end.
I would not recommend this company for the following reasons:1. Original appointment was very specific to them on what was needed and to take photos for 3 apartment unit plumbing fixture repairs. One unit had a bathroom tub/shower backup.2. No photos taken, 3 trips later and only 1 unit completed to satisfaction. (Backup) 3. Other faucets unable to find on line with their suppliers and repair 4. Had to find another plumbing company to complete the jobs. 5. Invoicing had to be redone as not in detail of job address for tax purposes 6. Bad communication throughout the project process with their internal customer service. Their technician and project manager ordering parts. 7. For the back up. Did not bring out correct snake on both trips and had to replace lines as too small to break through backup. Costing over $800 for 3 trips just to complete that situation out. 8. Ordered the wrong parts when 2nd trip out since no photos taken to confirm what was needed. Very dissatisfied and will never ask them to work in any of our rental properties again.
