The Importance of Measuring

Before we get into the nitty-gritty of how many gallons to paint exterior of house, it’s essential to measure your house correctly.

Calculating the Surface Area

To determine how many gallons to paint exterior of house, you need to calculate the surface area of your house. This includes the walls, trim, doors, windows, and any other areas you want to paint. Use the following formula:

Surface Area = 2 x (Length x Width) + (Perimeter x Height)

You can use online calculators or Excel to make the calculation process easier.

Factors Affecting Paint Consumption

When figuring out how many gallons to paint exterior of house, you need to consider several factors that can affect paint consumption:

Surface texture: Rough surfaces require more paint than smooth ones.
Color change: If you’re changing the color of your house, you’ll need more paint.
Primer: If you need a primer, you’ll need to add that to your overall paint consumption.
Number of coats: The more coats you apply, the more paint you’ll need.

Types of Paint and Their Coverage

Different types of paint have varying coverage rates. Here are some common types of exterior paint and their coverage rates:

Latex paint: 350-400 square feet per gallon
Oil-based paint: 300-350 square feet per gallon
Epoxy paint: 250-300 square feet per gallon

How Many Gallons to Paint Exterior of House: A Step-by-Step Guide

Now that you know the factors that affect paint consumption, let’s calculate how many gallons to paint exterior of house.

Step 1: Measure Your House

Measure the length and width of each wall, including the height.
Measure the perimeter of your house, including doors and windows.

Step 2: Calculate the Surface Area

Use the formula: Surface Area = 2 x (Length x Width) + (Perimeter x Height)
Calculate the surface area of each wall and add them up.

Step 3: Determine the Coverage Rate

Choose the type of paint you’re using and check its coverage rate.
Calculate the total number of gallons needed based on the coverage rate.

Step 4: Add 10% to the Total

To account for any mistakes or uneven surfaces, add 10% to the total number of gallons.

Example Calculation

Let’s say your house has a surface area of 2,500 square feet, and you’re using latex paint with a coverage rate of 375 square feet per gallon.

Calculate the total number of gallons needed: 2,500 square feet / 375 square feet per gallon = 6.67 gallons
Add 10% to the total: 6.67 gallons x 0.10 = 0.67 gallons
Round up to the nearest half gallon: 6.67 + 0.67 = 7.34 gallons

So, you would need approximately 7.5 gallons of paint.
