How to whitewash a deck

White outdoor decking area with planters and boots.

Overview

Whitewashing a deck can introduce a unique look to your outdoor area, brightening the wood to allow the natural grain to shine through. It adds a touch of added coastal flair, while also remaining texturally interesting and contributing to the idea of a summer retreat. Best of all, it’s incredibly simple and easy to complete in just a few hours. 

The techniques required for whitewashing are very similar to painting, making it an accessible project for any keen D.I.Yers. All you’ll need is a paintbrush, sandpaper and timber stain finish to ensure your new deck lasts for years to come. 

Steps

1

Gather your tools and materials

Below are all of the tools and materials you'll need to complete this project.
Brushes and brooms and paint.

2

Prepare your deck

If your deck already has a stain or varnish on it, you will need to get it back to a clean slate before you whitewash. Remove all furniture so that you can easily access the entire surface. Lightly sand the timber to remove all existing varnish and help the new paint adhere to the surface. Sweep away all dust before whitewashing.

Deck clean

Mix deck clean with water in a 1:4 ratio in a bucket. Once you have cleaned your deck with an applicator, leave it to dry for 24 hours.
