The final coat should always be cut in first and then rolled, preferably while the cut in paint is still wet. While it’s sometimes ok to take a wet paint roller and switch it directly to primer, you should never switch top coats without cleaning the cover up first!Click to see full answer. Likewise, people ask, can you use damp paint rollers?Before you do anything else, you actually want to wet the paint roller cover with water. “This primes the roller cover to soak up as much paint as possible,” Jessica explains. But don’t go too crazy—Jessica suggests removing excess moisture with a paper towel and a good shake of the roller so it’s just slightly damp.Additionally, how long can you use a paint roller? If you’re not going to be able to get back to painting for more than 12 hours or so, pull the sleeve off the roller frame and pop it into the refrigerator. There, it will stay fresh for up to four days. Take it out of the refrigerator—but don’t unwrap it—at least two hours before you’re ready to resume painting. Consequently, should you wet a paint roller before use? Before using a roller cover, it should be pre-wetted with water if a latex paint is being used, or mineral spirits for an oil base paint. The cover should then be spun or dabbed with a rag or paper towel to remove the excess liquid.Will roller marks go away when paint dries?Roller marks, which painters sometimes call “holidays,” are a routine hazard when painting with a roller, and there are many ways to avoid them. When you notice holidays after the paint has dried, you can usually make them disappear by applying another coat after sanding lightly—if necessary—to remove drips and humps.
