Dimensional paint is a type of paint which expands as it dries, creating a raised pattern. This popular craft product is also known as puff paint or puffy paint, reflecting the fact that it puffs up during the drying process. Many craft stores carry it in a range of colors and order special colors by request. It is also possible to order dimensional paint over the Internet, with some manufacturers selling directly to consumers.

Classically, dimensional paint comes in an applicator tube. Using a nozzle on the tip, a crafter can create a line of paint. Some come with tips which can be switched out, akin to pastry tips, to create other types of patterns and lines with the paint. Dimensional paint also comes in tubs, with people using a paint scraper or brush to apply the paint. The paint may also be mixed with glitter or glow in the dark materials to make it more visually interesting.

This paint was originally designed and marketed for use on fabrics. As a fabric paint, it usually weathers well through washing and drying, although it can start to crack and peel on a garment which has been worn a long time. The lifetime of a dimensional paint design on fabric can be greatly increased by handwashing and storing the garment flat, without folding, so that the paint does not develop creases or cracks. Exposure to high heat is also not recommended.

In addition to using it on fabrics, dimensional paint can be used on a wide variety of other surfaces. This paint adheres well to wood, paper, and other materials, although it can have difficulty sticking to things with a glossy finish. Puff paint can be used to make posters, unique greeting cards, and a wide variety of other crafts projects. As a general rule, dimensional paint does not mix well, so if additional colors are needed, they will need to be purchased.

One use for dimensional paint which people may not think of is as a tool for marking things for people with low vision. Vision impairments can make it difficult for people to determine whether switches are off and on and to perform other tasks requiring visual acuity, such as accurately identifying currency. Dimensional paint can be used to create small raised markers which people can use to assist themselves without having to rely on the assistance of someone else to help them identify something.
