Securing Half Pans: Preventing Watercolor Falls

how prevent half pan watercolors falling out

Watercolour pans can sometimes fall out of their slots, especially when the box is turned upside down. This is a common problem with plastic box sets, where the pans are not a tight fit. One way to prevent this is to use Blu-tack or White Tack to secure the pans. Another solution is to fill the pans with watercolour tubes, which can save money compared to buying new pans. When filling pans, it is important to allow the paint to dry completely in a well-ventilated area to prevent mould. Some manufacturers use honey to keep paints moist, but this can attract insects and make the paint too wet for certain climates. Glycerine can also be added to watercolours to prevent cracking and falling out of the pan.

Characteristics and Values

Blu-tack or White Tack Tear off a tiny bit and stick it on the back of the pan
Water Put a drop or two of water in the bottom of the pan and leave it to dry
Gum Arabic Put a drop or two at the bottom of the pan
Honey Use a small amount to make the surface sticky
Glycerine Add a drop or two to each pan
Distilled water Add a drop or two to each pan
Drying time Leave the pan to dry for at least 24 to 48 hours; avoid speeding up the process by heating

Use Blu-tack or White Tack

If you want to prevent half pans of watercolours from falling out, one way to secure them is to use Blu-tack or White Tack. These adhesive substances can be moulded into any shape and size, making them ideal for this purpose.

To use Blu-tack or White Tack effectively, start by tearing off a small piece and rolling it into a ball. You only need a tiny amount, so the ball should be quite small. Then, gently press the ball of adhesive onto the back of the half pan. Squeeze the tack gently so that it adheres to the pan, creating a flat surface that will stick to the palette.

Blu-tack and White Tack are useful for securing pans in place because they are removable and won't damage the palette or the pans. They are also inexpensive and widely available, making them a convenient option for artists.

It is important to note that Blu-tack and White Tack are not the only options for securing watercolour pans. Some artists prefer to use honey or glycerine to keep the paints moist and prevent them from falling out. Others suggest drying the pans completely and then refilling them, ensuring that the paint adheres to the inside of the pan. Additionally, some artists recommend using distilled water to soften the paint and then adding glycerine to prevent cracking and falling out.

Add a drop of water or Gum Arabic

If you are looking for a quick fix to prevent your half pan watercolours from falling out, adding a drop of water or Gum Arabic to the bottom of the pan is a simple and effective solution. This method is particularly useful if you are in a hurry and need a temporary solution to secure your pans in place.

To use this method, start by adding a small amount of water or Gum Arabic to the bottom of each pan. You only need a drop or two; a little goes a long way. Using a toothpick or a blunt needle, gently stir the liquid to ensure it is evenly distributed. If you are using water, you can also gently press your finger into each pan before it dries to create a small dent that will hold the water.

Gum Arabic is an excellent choice as it is already an ingredient in watercolour paints, so it will not affect the quality or performance of your paints. It is a natural adhesive and preservative, helping to keep your pans secure and your paint fresh.

If you are using water, this method may need to be repeated over time as the water will evaporate, especially if you are not using all the pans regularly. However, it is a quick and easy solution that can be done in just a few minutes.

This simple hack will help you secure your half pan watercolours and ensure they do not fall out, allowing you to focus on creating beautiful artwork without worrying about messy accidents.

Try using glycerine

Glycerine is a great option to prevent half pan watercolours from falling out. It is a substance that helps to keep the paint moist and less brittle. This is especially useful for watercolours that dry hard and crack, making them difficult to rewet.

When filling half pans, it is recommended to add a drop or two of distilled water to each pan first. Allow the paint to soften, and then add a drop of glycerine, along with more paint if there is room. Stir the mixture with a toothpick or a blunt needle. For Cotman watercolours, two drops of glycerine are recommended, while for Art Spectrum, one or two drops may be needed, depending on the amount of cracking.

Some brands, like QoR, do not require the addition of glycerine as they do not dry hard and crack. However, for brands like Daniel Smith, particularly the primatek colours, adding a touch of glycerine can improve the consistency and prevent cracking.

It is important to note that glycerine is not the only solution to prevent watercolours from falling out. Other options include using gum arabic, honey, or simply wetting the bottom of the pan with water.

Don't fill pans completely

When filling your half pans with paint, it is important not to fill them to the very top. This is because the paint will need to be stirred, and you will need to leave space for the paint to expand as it dries.

Firstly, squeeze the paint into the corners of the pan, rather than just squirting it in the middle. You don't want to fill the pan more than halfway. Stir the paint with a stick to avoid air bubbles from forming, and to help the paint adhere to the inside of the pan as it dries. You can also tap the pan on the tabletop to bring any remaining bubbles to the surface.

The pans will then need to be left to dry for at least 24 to 48 hours, but the exact drying time will depend on temperature and humidity. It may take a few days. It is important not to try to speed up the process by applying heat, as this could melt the pan or cause mess. It is best to let the paint dry naturally in a well-ventilated place, like a windowsill.

If your paint is taking a long time to dry, you could try placing the pan in sunlight, but be sure to leave the watercolour box slightly open to avoid melting.

Dry in a well-ventilated area

Drying your half pan watercolours in a well-ventilated area is essential to prevent mould and ensure proper drying. Here are some tips to guide you through the process:

First, squeeze the paint into the corners of the pan, filling it no more than halfway. This step helps avoid air bubbles and ensures the paint adheres to the pan as it dries. You can also gently tap the pan on a tabletop to bring any air bubbles to the surface.

Next, leave the pan to dry in a well-ventilated area, such as a windowsill. Avoid closing the palette and consider angling the pans for better airflow. The drying time can vary depending on temperature and humidity, typically taking a couple of days to a week. Avoid speeding up the process by using a heater or hairdryer, as this may cause mess or even melt the pans.

If you're filling half pans with tube watercolours, be aware that some paints may take longer to dry and may still feel a bit rubbery even after a week. However, you can use them at any stage of the drying process. Just add a few drops of water to rewet and reactivate the paint before each painting session.

Additionally, some brands may dry too hard and crack, which could cause the paint to fall out of the pans. To prevent this, you can add a drop or two of glycerine to the paint when making your pans. This is especially recommended for brands like Cotman and Art Spectrum.

By following these steps and allowing your half pan watercolours to dry thoroughly in a well-ventilated area, you can ensure the paint adheres properly and prevent any issues with mould or cracking.
