If you don't have any water to use, Elmer's Glue is probably your best option for a Floetrol substitute. You will get the same pouring consistency as Floetrol if you dilute your glue with water. Elmer's Glue-all (similar to Floetrol) will dry your painting to a matte finish.
In Acrylic Painting, you use water to dilute your acrylic paints. This works well, but is not recommended for Acrylic Pouring. Water not only changes the consistency, but also the pigment density and the adhesion of the paint to the painting surface. This means that the colors are lightened and no longer so bright.
Pouring medium recipe: Mix equal parts water and white glue in a jar and shake to mix. Add the pouring medium to the paint. I like to add it to half empty bottles of paint but you can mix it in other cups if your bottles are full.
If you want to try it without the price rage of expensive name brand mediums and the messiness of silicone, you can use Elmers Glue All (not school glue) and acrylic paints . It is important that you use liquid body acrylics for they lend themselves to be poured.
Well... you DO NEED a pouring medium, however, it doesn't necessarily have to be Floetrol. However, Floetrol is one of the cheapest options when it comes to pouring mediums. Even though Floetrol works great with acrylic paints, keep in mind that it has not been tested for art archivability over time.
Silicone Oil – Known for creating bulk, slightly larger cells in acrylic pouring. There are many different brands and you only need to add a few drops! 100% Dimethicone (In some hair oils) – The verdict is that yes this additive does create larger cells too. If you want to explore new substances give it a try.
A ratio of one part paint to three parts water should be enough to break down the acrylic binder so that the paint acts like watercolor. Also use fluid acrylics for glazing over another color, for creating drips (an eye dropper works well for this), for bleeding colors into each other, and for pouring.
a mix of equal parts water and white glue in a jar, shake it up a little to mix it out. Make sure your paint is covered in a medium that is poured. If you have enough bottles of paint, you can add it to half empty cups and mix it with other cups.
Most PVA glues, like School Glue, Clear Glue, and Elmer's Glue-All are slightly acidic. These glues will last years but will break down over time in part because of the acid. However, based on what we've seen from other artists, this time tends to be in the decades for acrylic pour art.
The pour – all poured the same, and tilted the same on the tile. No difference seen. Cells – the 100% Floetrol seemed to give better cells. There were fewer cells in the 100% Liquitex and the 50/50 mix did have cells, but they seemed to break up and go feathery where the paints seemed to mix.
Floetrol is not to be used as a paint thinner. It's best to use flat, eggshell or semi–gloss sheens. If you use Floetrol with a high-gloss sheen, it can minimize the shine. While it is milky in color but will not change the color of your paint because it dries clear.
The key to success for many beautiful acrylic pouring cells is the consistency of your acrylic colors mixed with pouring medium. Only if this consistency fits, you will prevent the different colors from mixing too firmly and the cells from running (too liquid) and cells from forming at all (too thick).
Why do you use a torch on acrylic pours? The use of a heat source on the surface of an acrylic pour helps break the surface tension of the top layer of paint. This allows lighter weight colors rise through the heavier colors and it helps close air pockets and bubbles that may form.
Elmer's Glue-All is a multi-purpose glue that works well as a budget pouring medium. It's non-toxic and has a similar look to professional pouring mediums that cost much more.
