In your project
Nothing measured yet. Your first wall takes about 20 seconds.
Will it fit?
A TV, a couch, a cabinet, a sign: enter the wall width and the object width and see it to scale.
Yes. Centered, it leaves 2 ft 3.5 in open on each side.
How much do I need?
Works for paint, tile, flooring or anything sold by coverage. Enter the coverage printed on your product's label; every product is different, so we never guess it for you.
You need about 4 gallons, boxes or bags. Most people get one spare for touch-ups. This is an estimate; the real amount depends on the surface and how it is applied.
