The key to any painting job is having the right tools.
These basic painting tools (tray, roller, cover, handle, and brush) are all you need for touch-up painting jobs.
If you are like most homeowners you'll wind up doing some painting, finishing, or refinishing over the next few years. Even if you decide to hire a professional painter for the big jobs, consider investing in a basic tool kit for painting projects. You always can expand it later as need arises and your are more comfortable with your painting skills.
A basic painting tool kit will include these items:
Paint brushes or paint pads for applying paint and other finishes to smaller surfaces (better brushes will cost more, but will last a lot longer and spread paint more easily and evenly)
Paint roller (frame and cover) and tray for applying paint and other finishes to larger surfaces (a better quality roller cover will last for years and apply paint more easily and evenly)
Cartridge gun for applying caulking and other sealers
Scrapers and sandpaper for removing paint and other finishes from wood, metal, or plastic
A-frame ladder or sturdy stepstool for reaching higher locations
