Hey there! As a supplier of Acrylic Wall Putty, I often get asked about the best way to store opened acrylic wall putty. It's a crucial topic because proper storage can significantly extend the putty's shelf - life and maintain its quality. In this blog, I'll share some tips and tricks on how to do it right.
First things first, let's understand what acrylic wall putty is. It's a popular material used for smoothing and finishing walls. It typically contains Acrylic Powder For Wall Putty, 42.5portland Cement, and other additives. When the putty is opened, it starts to interact with the environment, and if not stored correctly, it can dry out, harden, or develop mold.
Keep It Sealed Tightly
The most basic rule for storing opened acrylic wall putty is to keep it sealed tightly. Once you're done using the putty, make sure to close the container properly. If it's a bucket, use a rubber mallet to tap the lid back on securely. This prevents air from getting in, which can cause the putty to dry out. Air contains moisture and oxygen, both of which can have a negative impact on the putty. Moisture can cause the putty to clump, while oxygen can start the oxidation process, making the putty less effective.
Store in a Cool, Dry Place
Temperature and humidity play a huge role in the storage of acrylic wall putty. You should store the opened putty in a cool, dry place. A basement or a storage room away from direct sunlight is a great option. High temperatures can speed up the drying process of the putty, and excessive humidity can introduce too much moisture, leading to mold growth. Ideally, the temperature should be between 50°F - 70°F (10°C - 21°C), and the relative humidity should be below 60%.
Use a Desiccant
To further protect the putty from moisture, you can use a desiccant. A desiccant is a substance that absorbs moisture from the air. You can buy silica gel packets from a hardware store and place them inside the container with the putty. These packets are commonly used in food packaging and electronics to keep them dry. Just make sure the silica gel packets are clean and don't come into direct contact with the putty.
Check Regularly
It's a good idea to check the putty regularly, especially if it's been stored for a long time. Look for any signs of drying, hardening, or mold growth. If you notice a thin layer of dry putty on the surface, you can try to mix it back in gently. However, if the putty has hardened significantly or has mold, it's probably best to discard it. Moldy putty can release spores that are harmful to your health, and hardened putty won't be suitable for use.
Label the Container
When you store the opened putty, label the container with the date it was opened. This helps you keep track of how long it's been stored. Acrylic wall putty usually has a shelf - life of about 6 - 12 months after opening, depending on the storage conditions. By knowing the opening date, you can decide when it's time to use it up or replace it.
Consider Transferring to a Smaller Container
If you have a large container of putty and you've only used a small amount, consider transferring the remaining putty to a smaller container. This reduces the amount of air space inside the container, minimizing the contact between the putty and the air. Make sure the smaller container is clean and dry before transferring the putty.
Mix Before Use
Even if you've stored the putty correctly, it's a good practice to mix it thoroughly before using it again. Over time, the components of the putty may settle, and mixing ensures that the putty has a consistent texture and performance. You can use a drill with a mixing attachment for large quantities or a putty knife for smaller amounts.
Avoid Contamination
When using the putty, make sure to use clean tools. Dirty tools can introduce contaminants such as dust, dirt, or old putty into the container, which can affect the quality of the remaining putty. After using the tools, clean them thoroughly with water and let them dry before using them again.
Be Aware of Chemical Reactions
Acrylic wall putty can react with certain chemicals. Keep it away from solvents, acids, and alkalis. If the putty comes into contact with these chemicals, it can change its properties and become unusable.
Store Away from Flammable Materials
Although acrylic wall putty is not highly flammable, it's still a good safety practice to store it away from flammable materials. This reduces the risk of fire in case of an accident.
In conclusion, proper storage of opened acrylic wall putty is essential to maintain its quality and usability.
