    You can add an acrylic medium to your paint to thicken it up and give you the option to add texture. You don't mention what you are painting that needs texture. That information would be helpful in getting some more specific answers to what you are trying to do.

  • Here is a great video that shows some products you can add to thicken it:

    Hi Grandma Pat. You can thicken acrylic paint with corn starch. Before you add the corn starch to the acrylic paint, you must first mix it with water. Use a ratio of one and a half-cups of cold water to two tablespoons of corn starch. Once it is well mixed, put it on the stove over low heat. Heat the mixture while stirring continuously until it forms into a paste. Let it cool completely before adding it to the paint. Add a little at a time mixing well after each addition. Good luck Grandma Pat. Hope all is well with you.

    you can use hardware store materials for texture. Try adding stucco patch or cement mixed with glue. Works great and a ton cheaper than texture you get from liquitex. Experiment.... It won't be as smooth but if you are just trying to add texture to a painting, this might be all you need. If you don't want to make it and price doesn't matter you can buy texture (liquitex) already made. Here is an artists site. You will have to search around for just the type of texture you need:

    Hello Grandma Pat: Here are some sites that should help you out:;

    It is possible that cornstarch as a thickening medium will not allow the painting to age well. The same with flour and baby powder. However, if you want to give it a shot, using cornstarch is pretty simple: Combine 1.5 cups of water with 2 tablespoons of cornstarch in a saucepan over low heat until a thick consistency is formed.

    Good luck
