Divide the previous number by the calculated square foot coverage pointed out on the paint’s cans. This number will give us the correct quantity of gallons for every single coat.

However, it is safer to add an additional gallon to the number collected after the division.

For the gable ends, calculate the needed amount of the extra paint by measuring the height and width of every gable end. Multiply these numbers and then divide it by 2.

You will receive the square-foot dimensions of the gables to add in your paint estimation.

Always remember that different exterior wall surfaces including masonry, shingles, and stucco may need 10%-15% extra paint than the smoother and flatter walls with the similar square footage.

Spraying needs more paint since the sprayer will atomize all the paint prepared into smaller droplets. Then, most of them end up covering on the wall surface while the others may drift away. Paint spraying can’t control the issue effectively.

To decrease the paint amount required when you spray your house, follow these following steps:

Avoid the wind: A slight 5-mph wind can blow away the sprayed paint. Avoid the windy days if you don’t want the paint consumption is up to 50% of your estimated paint.

Pump the paint back: Once you finish your project, spray out all the rest paint into the air. Alternatively, pump the paint back in the hose into the previous can.
