When you have to have latex paint during the colder months, freezing can become a problem. This is particularly bad because as the water in the paint freezes, the entire substance can become thick and grainy, making it completely unusable. However, if you detect freezing early enough, all hope is not lost. Here are some steps you can take to see if it is recoverable.
Step 1 – Stop freezing with proper storage
Prevention is always the best and easiest remedy. Instead of storing your latex paint in a place where freezing may be a problem, be sure to keep it in a dry, temperature-controlled environment, such as a basement (in a state) or the bottom of a closet. Avoid places with high humidity, as the metal in the can will rust around the lid. Also avoid places that can get too hot; high temperatures can destroy water-based paint as easily as low temperatures.
Step 2 – Defrost
For starters, your frozen paint needs to be thawed. Placing the newspaper on a flat surface, then place the can on top. Let it sit at room temperature for several hours until the ice has had a chance to melt. Do not try to speed up the process by adding heat; This will only make problems worse.
Step 3 – Stir
Then you must remove it. Open the paint can and quickly check the color so the freezing temperatures haven’t quickly altered it. You should also check for consistency. If it hasn’t been frozen for too long, its color and consistency may be fine.
Step 4 – Filter the grain
If you have noticed that your color is fine, but that the paint looks thick and grainy, you may be done. At best, its consistency will be smooth when shaking, as a cottage cheese-like texture almost always means that the paint is worthless. However, if the paint is not too thick and the grains are few and far between, you can sift them and use the rest.
Place a sieve bowl in or on top of a container (something you obviously don’t mind painting) and pour the paint through it. The bowl should catch all the granulated pieces, leaving behind the ideal smooth consistency you are looking for.
In the event that your attempts to restore your painting have been unsuccessful, be sure to dispose of it properly. Check your local household hazardous waste laws for instructions on what to do.
At the end of summer, a Twitter follower (thank you Laura) recommended the entry Tempera Ice from the blog En el mundo de las fadas . In it the author explained a very cool activity she had done in the summer with her children. I loved it and as soon as the course started I got down to work.
The material needed is: 1. Tempera 2. Ice buckets (with a coarse) 3. Continuous paper or DinA3 card stock 4. Little bowls to leave the ice 5. Fine or medium brushes
The first thing we have to do is fill the ice buckets with tempera and water and stir well with a stick (or with the back of a brush) and quickly take them to the freezer. If you want to get bright colors, fill almost all the tempera hole and very little water. The first time I poured enough water (look at the images) and I had pastel colors. In addition, in the time that passes from the time the water is mixed with the tempera until it freezes, the tempera “settles” at the bottom of the hole in the ice bucket, so if you add little paint, part of the ice cube will be very clear ( practically just water) and all the paint will be on the other end.
I put on all the colors and my partner only shades of blue and green because she wanted to make a seabed. This time I have used some new tempera from La Pajarita that are super washable and great because they really are (the sleeve of a white shirt stained purple and it has been removed !!).
We left them one day in the school freezer and the next morning, just before the activity began, we went to look for them. I made the paintings in the art corner. I left each cube in a small custard jar and the children who went to the corner painted with them completely independently. We maintained this phase of the activity throughout the week, so each day I had to replace the ice buckets and take them back to the freezer so that they would be frozen the next day.
As you can imagine, they loved it! Painting with something so cool caught their attention a lot and it was almost magical that as they used the ice cubes they melted. Also, it seems to me that it is a very good activity to work fine motor skills because taking the ice cube without it leaking and handling it on the paper requires a firm grip with your fingers and it was not always easy for them.
Throughout this week we also left colorless cubes in the class to observe how they changed from solids to liquids throughout the morning. The following week, also in the art corner, we painted on the background that we had made with the cubes. In this case I wanted something similar to what I had seen on the blog My plastic techniques for hangers (my colleagues say that I have many ideas … but if there is so much generously shared on the internet … !!).
I left them only red, purple and black tempera not at all watery and fine brushes and I proposed to draw them (as it was the beginning of the course I was interested in seeing how the drawing of the human figure had evolved ). And this was the wonderful result !!
I have done the activity with my 4-year-old students but I think it can be done perfectly in 5 years with autumn hues now that we enter this season, and it is also ideal for the end of the 3-year course, when it starts to get warm .
