Wondering how to weatherproof acacia wood? You’ve come to the right place!
Acacia wood is a beautiful and unique type of wood that can be used for a variety of different projects. However, if it’s not properly weatherproofed, the wood can become damaged and weakened by the elements.
One of the best options to protect acacia wood outdoors is to get some patio furniture covers. These are easy to store, light-weight, and a simple solution that keeps your outdoor patio furniture in-tact.
However, if you’d prefer to avoid using covers, keep reading and we’ll show you how to weatherproof acacia wood using a few simple steps.
Waterproof Finish for Acacia Wood
If you want to put your acacia wood furniture outside, you’ll need to use a waterproof finish. Acacia wood is water-resistant but not completely waterproof. If water penetrates the wood for a prolonged period of time, rot or mold can form inside.
A waterproof finish for acacia wood is ideal if you plan to keep your wood outside. However, equally important to consider is how the sun will impact your outdoor furniture. Regardless of whether or not you choose to use a finish for your acacia, we recommend using covers if you plan to store it outdoors.

You can seal the wood yourself to protect it from the elements. Look for a sealant that is oil-based like Seal Once for maximum protection.
To apply the finish, start by sanding the wood thoroughly. This process will create a smooth surface for you to work with. Wipe off any dust or dirt particles. Once it’s completely clean, apply your waterproof finish using a brush or spray.
Another option for water protection is applying tung oil, teak oil, or linseed oil. The oils offer less protection from water than sealants do, but they are easier to apply.
Protecting Acacia Wood From UV Rays
Acacia wood can also be damaged by too much sun exposure. If you place your acacia wood furniture outside, it is likely that it will be exposed to direct sunlight for at least part of the day. Sunlight can cause the wood to fade and crack as well as make it more prone to water damage.
Luckily, there are ways for you to protect your acacia furniture from direct sunlight as well as indirect sunlight. You can stain your wood after applying a sealant, or use a pigmented oil finish for enhanced UV protection.
Simply cover the outside furniture when it is not in use. This will prevent UV rays from reaching the wood and causing any damage. Rotate the furniture periodically as well as move it to a shaded area if possible.

Closing on How to Weatherproof Acacia Wood
Protecting your acacia wood from the sun is important to keep it looking beautiful. Applying a sealant or tung oil will make sure that moisture doesn’t seep in and cause any damage, but you can also rotate your furniture periodically so one side isn’t always exposed to direct sunlight.
It’s best if you can cover up your outside furniture when not in use as well due to UV rays which are harmful for all types of materials including acacia wood.
