Installing Allure Vinyl Flooring from Home Depot in the 13' Scamp.  Just tore out the rug, came out ok except for that yellowish orange foam that didn't easily remove in some areas.  We pulled off all the fuzz portion but the reallly light layer stuck to the glue stayed on.  We sanded/scraped it pretty good.  I'm nervous if we scrape anymore we're going to start sanding the wood,  is this ok can we just put the floor on or does this need to be removed?  This vinyl floor is floating and fairly heavy seems like it won't be effected at all but also don't want any reprocussions from not doing it propertly.  Thanks!
