We’re big fans of the standard ScotchBlue painter’s tape ($7.30, Amazon) for taping off trim and ceilings. For detailed work, like creating stripes or working around glass, FrogTape ($5.63, Amazon) creates a tighter seal around the edges.
Having a drop cloth will mean less clean up later. Use it to protect floors and furniture from drips of paint. Really, no matter how careful you are, there will be drips. Scotch Plastic Drop Cloth ($12.58, Blick) is a great temporary option – just crumple it up and dump it in the garbage when finished. If you think you’ll be painting again the future, consider investing in Blue Hawk Canvas Drop Cloth($21.98, Lowes). You can always use it to make a slipcover or curtains later. Another option is to buy a Kraft Paper Roll ($26, Uline) to protect your floors. The extra kraft paper has myriad uses!
One annoying thing about most paint trays is that you have to refill them repeatedly throughout the job. The clever thing abuot the Bercom Handy Paint Tray ($11.15, ThePaintStore.com) is that it fits an entire gallon of paint. Plus, it includes a magnetic brush holder and handle.
