Morning after rasping can be tough going! No experience of the power rasps but id say its better to do it by hand for the finish though..

When possible prefer to use an i_beam. Normally scratch first coat with sand cement then one coat of krend and try scrape same day. Now on jobs where it's hander to double coat the krend but scrape next morn but the type of block are leaving it bit hard thought the electric scrapper mite break up the top and leave it easier to work
