Glue-Tempera Paint Ratios For Plastic: Achieving The Best Adhesion

Tempera paint is a permanent, quick-drying coating, consisting of pigment and a glutinous binding agent, like egg yolk. It will not stick to unsanded plastic, but you can add white glue to it and it will adhere. You can also add water to the glue and paint mixture to make it similar to acrylic paint.

Tempera paint won't stick to plastic

However, there are ways to make tempera paint stick to plastic. One way is to add white glue to the paint. You can also mix tempera paint with other elements such as salt, flour or sand to create a thick textured paint. Another option is to cover the plastic surface with strips of masking tape and then paint on top of that.

If you are decorating a plastic bottle, you can try tearing off pieces of tissue paper, painting a liquid glue/water mixture over the bottle, adding the tissue paper, and then painting another layer of glue/water mixture. This method does not use tempera paint, but it is a way to add colour and decoration to plastic.

It is important to note that tempera paint will not adhere to unsanded plastic. Therefore, if you are trying to paint plastic, it is recommended to sand the surface first to ensure proper adhesion.

You can also mix tempera with other elements such as salt, flour or sand to create thick textured paint, or add white glue and water to make tempera similar to acrylic paint.

Storing tempera paint

To store premade tempera paints, you need a sturdy, reliable container. Plastic squeeze bottles are especially convenient as they double as applicators, allowing you to easily dispense just what you need. If their lids are secure, they can also be used as mixing vessels. These plastic bottles may be unassuming, but a good-quality product can prove to be more useful than you might think. Each features clearly printed fluid ounce and millilitre measurements so you can easily stick to your desired ratios when mixing media.

Plastic tubs with airtight lids are the best way to store water-based paints.

Small paint holders are ideal for saving small amounts of leftover paint or for experiments with mixing colours. Each features a soft plastic lid that pops on and off with ease. This is not a super-secure seal, but the jars do provide quick and frustration-free access to paints as well as a simple solution for short-term storage.

Colorations’ cups are smaller than Melissa & Doug’s—each well holds four ounces of liquid—but they too feature lids with holes for paintbrushes and a top that snaps on tightly to guard against spillage. Sargent’s cups are sold by the dozen, which makes this an economical pick for artists who work with many colours.

Each 12-ounce cup features a smart pairing of two lids: a funnel top that screws on, with an opening for dipping brushes, and one that snaps on top of it when you’re done painting. And as long as you maintain paint levels below the cup’s fill line, the design will prevent accidental spills and leaks.
