Thanks for knowing the differences are. Though I have lingering questions, as this is related to primers: 1. I've seen some people using GAC to size their canvas or paper before priming it with gesso. I've read that GAC is made PVA and water, and I have thought if Elmer's glue diluted with water would be a substitute or if acrylic gesso is already enough since it's both sizing and primer according to Blick. I would assume that gessos from several brands have differing ingredients and proportions. I have considered making my own gesso out of household materials to save money. 2. I have a big bottle of acrylic emulsion (the flowy milky fluid that dries clear and glossy) my art teacher recommended me as a varnish for canvas. The acrylic paints I used when I stared in acrylic painting was house paint that dried matte. That emulsion is intended as a sealant and varnish for concrete walls. I have bought an acrylic medium intended for artwork and I noticed the emulsion and the medium have the same flow and coloration. Does the emulsion have additives that would prevent me from using it as an affordable acrylic medium and/or an ingredient for a homemade gesso?
1. You can yeah, but too much water and the canvas will absorb it and mold over but too little and it can get cracking issues so getting the ratio right is the tricky part, which i dont know the ratio since ive never done that. I've always just used gesso or gac. 2. I'd have to know the brand and generally varnishes are chemically different than binders so you cant use one as a primer per say.
@MrPigments 1. I think I'll settle for gesso in my sketchbooks and canvases for now, as I have been doing acrylics again for the past few months. I have been aiming on homemade gesso with acrylic, PVA glue, and chalk, though I'm not sure what would be the disadvantage if I pick the wrong proportion. 2. I'm using a Filipino brand called Bronco. There's another Filipino brand named Boysen that has this. It's primaily used as a waterproofing sealer and coat for concrete and stonework. Not sure what emulsion is called in America. I'm not sure if hardware stores sell acrylic medium binders or an equivalent to it.

Thank you for making this, I think I'd like to keep on the lookout for some high flow medium. I have run into some issues with making washes some paints with water, so it sees useful to have on hand. Maybe get closer to what you can do with acrylic inks.
@@SentientTent it's very useful to have on hand in my opinion. It's watery thin so it has great applications for washes and thinning heavy bodied acrylics down a lot
Sadly brand matters with this stuff. When I started airbrushing I used the Airbrush Thinner and Flow Improver from Vallejo in a mix like Vince Venturella suggested it on his channel, which doesnt work for me well "somehow". I used the mix for brush work once and found that the Flow Improver doesnt really act like a drying retarder. I got Flow Improver and "Slo Dri" from Liquitex and that stuff works like a charm. I dont have to think about how to use it, since it exactly does what it states on the lable
@@alternate3787that is because Vallejo does not use proper chemicals in their products. It is also not a reputable brand as in the professional art scene, their reputation is very lackluster to put it nicely. Their flow improver is butoxy ethanol which is a speed dryer in paint not a flow improver but can help with improving flow rates in theory.
I was told at some point that Airbrush Flow Improver and "regular" or Flow Improver intended for use with brushes are two different things and that regular flow improver isn't very good to use through an airbrush because it means the paint won't atomise properly, or at least as easily. Is there any truth to this?
Thanks for the video, appreciate it!

@AlexYorim 1. I'll make a gesso video at some point. I just need to get more chalk as I'm out.
2. I'll look into those brands, thanks.
@MrPigments 👍🏽🧡
