Before you start thinking about painting, you should consider that you must have certain tools at hand, to make it easier and faster.
Cloth: This is essential to clean as necessary the paint that is falling and thus avoid having a bad result.
Paint tray. They are essential for any interior wall that requires a roller, preferably one that hooks onto the ladder for greater mobility.
Brushes and rollers. There are many options for painting but consider the spaces you are painting; Smaller ones can help get the hard-to-reach spaces, while wider rollers can cover larger walls.
