Why wax is important for mushroom logs
Waxing mushroom logs is important for several reasons. Firstly, it helps control the water content inside the logs, ensuring that the mushrooms have access to the right amount of moisture for optimal growth. Secondly, wax acts as a protective barrier, preventing insects, birds, and other contaminants from reaching the mycelium, which is the sweet-smelling part of the mushroom log that attracts pests.
Wax also seals the inoculation sites on the logs, protecting the spawn from drying out and contamination. This is critical to the success of mushroom cultivation as it creates an optimal environment for the mushrooms to grow and thrive. Without proper sealing, the spawn may be exposed to harmful elements that can hinder their growth or cause them to rot.
The type of wax used is also important. Food-grade paraffin wax is commonly used for sealing mushroom logs as it is safe for consumption and effective at creating a protective barrier. However, some people choose to use alternative waxes such as beeswax, as there are concerns about the potential hazards of using paraffin wax, especially when melted and applied with a flame.
When waxing mushroom logs, it is essential to consider the temperature and application method. Wax can be applied using a paintbrush, dauber, or specialised tools such as the Okuda Wax Application Tool. If using a flame to melt the wax, it is important to monitor the temperature as wax can get extremely hot, posing potential safety hazards. Additionally, when applying wax in temperatures below 50 degrees Fahrenheit, it is recommended to use a plugged-in crockpot to prevent the wax from hardening quickly.

Types of wax to use
When sealing mushroom logs, it is important to use the right type of wax to protect the spawn from drying out and contamination. Here are some types of wax that can be used for this purpose:
Paraffin Wax
Paraffin wax is a commonly used option for sealing mushroom logs. It is available in blocks or granules, with the latter melting more quickly and smoothly. It is important to note that some sources advise against using paraffin wax due to potential hazards and the preference for more natural alternatives.
Soy Wax
Soy wax is a natural alternative to paraffin wax. It is durable yet flexible and has a lower melting temperature, making it safer to use. Soy wax is also easy to use and comes with detailed instructions, making it a popular choice for those seeking a more sustainable option.
Beeswax
Beeswax is another natural option that can be melted and brushed onto mushroom plugs. It is a good alternative for those looking for a more eco-friendly and sustainable choice compared to paraffin wax.
Plug Wax
Plug wax is specifically designed to protect plug spawn inoculation sites without the need for hot wax. It is pliable and can be applied using daubers or wool balls, making it a convenient and safe option for sealing mushroom logs.
When choosing a wax for mushroom logs, it is important to consider factors such as ease of use, melting temperature, and environmental impact. Each type of wax has unique characteristics that may make it more or less suitable for specific needs and preferences.

How to melt wax
To melt wax, you can use a double boiler, a microwave, a wax melter, or a hair dryer/heat gun. Here is a step-by-step guide for each method:
Double Boiler Method:
- Fill a large pan with water, about halfway full, and place it on a stove or hotplate to heat.
- Place your wax in a smaller pan, glass bowl, or pouring jug. Do not fill the container more than halfway to avoid spilling hot wax when moving or pouring it.
- Put the smaller container with the wax inside the large pan. Heat over medium heat until the wax has melted.
- If desired, you can add colourant to the wax when it reaches 70°C.
- Remove the wax from the heat and let it cool to 65°C. At this point, you can add your chosen fragrance, if desired. Stir gently for about a minute.
- Your wax is now ready to be poured into a mould or used for its intended purpose, such as sealing mushroom logs.
Microwave Method:
- Use a microwave-safe container, such as a glass or ceramic bowl, or certain types of plastic containers that are labelled microwave-safe or heatproof.
- Pour your wax into the container, taking care not to fill it more than halfway.
- Place the container in the microwave and heat for one minute at a time, monitoring the temperature until it reaches 80°C.
- In between each interval, stir the wax and use a thermometer to monitor its temperature.
- Once the wax is completely melted, remove it from the microwave and set it aside to cool.
Wax Melter:
- Place the wax melter on a table or counter, with the spigot over the edge, so you can easily pour out the melted wax later.
- Plug in the wax melter and set the temperature according to the type of wax you are using.
- Place the solid wax directly into the wax melter pot.
- The wax will melt and can be poured out through the spigot at the bottom.
Hair Dryer or Heat Gun:
- Wipe away any dust or debris from the top of the wax with a paper towel.
- Turn on the heat gun or hair dryer and set it to high heat.
- Hold the heat source about 6 inches above the surface of the wax.
- Use a wick dipper or a toothpick to gently prod any unmelted wax stuck on the sides.
- Continue until the wax has liquefied evenly across the surface.
When melting wax, it is important to take safety precautions. Never let the temperature of the wax exceed 80°C or 250°F. Always use a thermometer to monitor the temperature and never melt wax over direct heat, such as placing it directly in a pot over a stove. Keep melted wax away from children and pets, and always use potholders or oven mitts when handling hot containers.

Application methods
When applying hot wax to mushroom logs, it is important to consider the type of wax, the tools required, and the specific application process.
Wax type:
It is recommended to use a high-quality, food-grade wax specifically designed for sealing mushroom plugs and logs. Some sources suggest using natural soy wax, as it performs better than paraffin wax. Soy wax remains flexible in cold temperatures and adheres well to the plugged logs. Granules are also preferred over blocks as they melt more quickly and smoothly.
Tools:
To melt the wax, you will need a heat source such as a stove, camp stove, or rice cooker. Use a double boiler or a can placed in a pot of water to melt the wax indirectly. A brush, dauber, or turkey baster can be used to apply the melted wax to the inoculation sites. The Okuda Wax Application Tool is specifically designed for sealing sawdust or plug spawn.
Application process:
Before starting, ensure your mushroom kit is fresh, as they are best started within a week of receiving them. If necessary, you can safely refrigerate the kit for up to 4 weeks. Pick out your mushroom plugs and logs, then follow these steps:
- Place the wax in a heat-safe container, such as a can or a double boiler, and heat it indirectly over your heat source until melted.
- Use a brush, dauber, or turkey baster to apply the melted wax to the inoculation sites, covering the mushroom plugs and log ends.
- Allow the wax to cool and solidify, creating a seal that controls the water content inside the logs and protects against insects and birds.
Remember to exercise caution when working with hot wax, and always follow the specific instructions provided with your chosen wax product.
