I was very nervous before using the Bona Mega One product after reading other reviews BUT, after following instructions and DEFINITELY using a paint screen/filter to filter product before using it went down EASILY, I was so worried about puddles and lines but everything just Layed flat and ended up absolutely BEAUTIFUL!! It was my first time doing this size of a refinish product and glad I spent the money for this. You do need to work fast though, have everything ready and a plan. I did one bedroom first as a test and found i could do my entire 3 bedroom/living room in a couple hrs. Wait to dry, light sanding to knock off any imperfections with a screening machine, repeat a couple times, stand back enjoy your work! ( it's only going to be as good as the time you take to prep...sanding, vacuum, clean clean clean)
