The Boy Scout motto "Be Prepared"also applies to do-it-yourselfers and homeowners planning to purchase paint. Although the quality of the paint should always be top-of-the-line, the quantity of paint needed will vary, depending on the type of project undertaken.

You can save time and money by estimating your paint needs before you come into buy your paint. Below are some tips to help size up your paint job, and determine the number of gallons required for your project.

The easiest way to estimate the amount of paint you'll need is to measure each surface area to be painted - multiplying the height by the length or width. Duplicate this calculation for the areas that won't be painted over, like doorways and windows. Then, subtract the non painted areas from the overall surface area to get an estimate of the square footage to be painted.

The next step is to look at the paint can label to determine the spread rate, which is usually 250 to 350 square feet per gallon. Divide the total surface area to be painted by the spread rate to determine the number of gallons you'll need for each coat.

A number of factors -like the type of paint, the color you are applying and the nature of the surface -dictate the number of coats you should apply. For example, you will likely need a second coat of paint when covering a dark color with a lighter one. Also, masonry surfaces like stucco are very porous and absorb a great deal of paint. Hence, a second coat is often needed on these types of materials in order to get a uniform appearance.

For exterior paint jobs, we recommend applying two coats of top qualitypaint for the best durability and colorfastness. Two-coat coverage stands up to the demands of weather and environment better than one-coat painting.

The worksheet below will help you calculate how much paint you'll need for your project. If you have any questions, your salesperson can also help you with your estimate.

In the final analysis, taking time to think through your painting projects before you begin will pay big dividends in time and money saved. It's the smart way to paint.

To compute the number of gallons of paint you'll need to cover the exterior of your house based on a 2000 sq. ft. home, use this worksheet.

Remember, the worksheet below is for one coat. Double the total if you are applying two coats.

1 quart will do approximately 4 doors 1 side only. 1 quart is generally more than enough.

2 gallons is enough to do approximately all gutters, facias and window trim. Buy more as needed, especially if you are doing more trim areas than mentioned.

width of all walls added together _______ X heigth of house from foundation to roofline _______= wall surface ______ (make no deduction for door and window openings and you will have enough paint for the gables and a 2 foot eave overhang, if there is a flat roof deduct window and door opening areas. You may need more paint for extra large eave over hangs)

Divide wall surface area by 250 to 350 sq. ft. per gallon (see paint can lable and use lower quoted coverage) = gallons needed for walls ________.

*note. Previously unpainted stucco sided homes (stucco that is color coated - that is where the stucco was dyed) will use a tremendous amount of paint.
