The formula is as follows:
Multiply the height of the wall by the length of the wall.
Multiply the height of the door by the width of the door.
Subtract the total of the area of the door from the total of the area of the wall and the resultant number is the total square footage.
10 X 20 - (7 X3) =
You do the math.
If it is just finished drywall then yes, it needs to be painted.
The answer depends on the preparation of the surface to be painted and on the paint, itself. Read the coverage information on the paint can.
No! It is better to say 'The paint on the condensor body has been burnt so it needs to be painted again'.
Different types of paint have different coverage. The answer will also depend on the the surface to be painted. Porous surfaces will require more paint. A surface with a strong colour that needs to be hidden will require more paint. A surface that is smoothed and well primed will require less. The paint tin should give an indicative answer.
Polyethylene can be painted with a moderate amount of success if properly prepared. You should only use acrylic paint on polyethylene. The surface needs to be cleaned and scuffed up with a fine grit sandpaper to hold the paint.
The price per can is unnecessary information. What we do need to know is the area (or dimensions) of the surface[s] to be painted.
It is "have painted" or "has painted."
The coverage depends on a number of factors such as the paint itself, the porosity of the surface being painted, preparation and do on. Your best option is to read the label on the paint container.
Who painted is correct.
Paint can be applied over varnish, but it needs to be a compatible type of paint for the type of varnish, and the surface needs to be prepared by removing loose material, dirt and sanding. If it is not a compatible paint the surface needs to be etch primed. Contact a local paint supplier for advice.
The past tense of paint is painted. Had painted is the past perfect tense.
The coverage will depend on the paint itself and on the state and preparation of the surface being painted. Look at the pain tin for its coverage.
