Deck Stain Definition

When you have decided to stain your deck, you can be left wondering how much stain you need to buy. It is not fun to get started on a project and realize shortly into it that you don’t have enough supplies. You also don’t want to have a lot of stain left over either. To determine how much stain you will need, use our calculator to help you out.

Measurements Needed to Use Calculator:

  1. Length of Deck
  2. Width of Deck
  3. Railing Length
  4. Railing Height
  5. Number of Steps
  6. Width of Steps

Measuring how much stain you will need is very easy. All that you are going to need is your tape measure and our calculator. Use the instructions below to help you find the measurements.

1. Measure both the lengths and the heights of the deck that you want to cover. If the area is irregular, fit that area in a rectangle and measure that rectangle for its length and height. Then add the amount into the calculator.

2. Now you will need to measure both the lengths and heights of the railings. When you have these measurements, put them into the calculator.

3. Next, you will need to first count the number of steps on your deck and then measure them. When you have the number of steps and their measurements, put those numbers into the calculator.

After entering all of the above information, the calculator will tell you how much square footage you have that needs to be covered and how much wood cleaner or stain you need to buy. When you buy the stain for your deck, make sure to read the maximum amount of square footage it can cover. Use this to determine how many gallons to buy in order to finish staining your deck.
