DIY gesso and using PVA glue as a primer and varnish.

Brilliant DIY Dave👍👍👍👍

[@piltthom]

Thanks Dave, I was wondering how you introduced the chalk. Great DIY piece. Thanks very much. Getting ready for 3 rainy days here in Ohio. Looks like a wet Fathers day. Happy Fathers day to you. Enjoy

DIY DAVE...... LOVE IT , good to watch Dave great tips, wet wet wet up north no barbique for me that's for sure..lol

[@annettefournier9655]

Thanks for the demo Dave. Mixing it on the paper looks much easier than what I blindly did. 😂😂 It is a bit scary dumping glue onto a watercolor. My stomach did a little flip. 😨😂. Nice protective finish though. Thanks again. Enjoy the barbecue. Rain again here.💙💜

Hi Dave. I experimented with the varnish on a piece I wasn’t that concerned about. It disturbed the paint a bit. It had been sitting for a couple of weeks so it was dry. Any ideas?

[@DaveUsherArt]

I don't use it on watercolours Joe if that's what you did. I used it dilute to varnish acrylics. A couple of coats and the milky look is a bit scary but it dries transparent

[@joemenzaart]

Dave Usher oops lol. Actually when it dried it looks pretty good.

Enjoy your videos, and a nice tip. I assume PVA glue is the same thing as Elmers glue in the states?

[@piltthom]

Yes, that’s correct. Elmer’s glue or student glue, or school glue. When to get it here in the US and nobody knew what I was talking about when I said PVA.

[@piltthom]

PVA glue, or polyvinyl acetate, is also known as school glue or white glue. It can be made at home with ten ounces of water, three tablespoons white flour and one tablespoon of sugar. Chill two ounces of water and mix in flour until smooth. Boil the remaining eight ounces of water. Once boiling stir in flour mixture over heat until thick while mixing constantly. Remove from heat and mix in sugar. Refrigerate until cool and the substance is ready to use as glue. This home made glue is as durable and strong as store bought school glue. Found this on my search.

@@piltthom And how many magic beans? Where in your recipe is the PV part?

[@mikecomley]

Hi Dave.....Well explained. Love your work..........Could this method be used on canvas panels too?

[@DaveUsherArt]

It would, Mike but if the canvas is unprimed, you should use an acrylic gesso. Most canvases are pre primed with a white acrylic primer

[@zy6747]

are you able to use PVA without chalk/plaster? what's the purpose of chalk? thanks!

[@DaveUsherArt]

Yes, the chalk/plaster etc. powder thickens the gesso and makes the painting look as if you've used a lot of paint. Doesn't work with painting knife though. Try it and see. :)

@@DaveUsherArt thanks for your reply!:D

[@RaymondOreFineArt]

I wonder if you could put kaolin clay powder in there instead of the chalk and make clayboard?

[@TTomJohn]

Thanks, Dave. Very generous, very helpful! Clearly explained and demonstrated. 🖒 Same process for MDF?

Dear Dave I lost my recipe for covering an oil on canvas painting with homemade gesso. This must be stable to cover - paint over - with a ‘new’ oil painting. Can you help please. My professor showed me back in the day- she used household Dulux Velvaglo good quality paint, Coldglue / Whiteglue and liquid Glycerine . I forgot the proportions. The failed old oil painting will be very dry- even years old . I did this 21 years ago and the ‘new’ oil on canvas shows no signs of instability. Does the glycerine surprise? She said it was essential. Looking forward to your reply. Kind regards Adrienne

[@DaveUsherArt]

I use 2 coats of white acrylic household emulsion on watercolour paper for oil. I have so many paintings and no stretched canvases to fill the remaining space, Adrienne. You can prime with PVA glue diluted on canvas; also combined with acrylic paint. I only use a spray varnish on oil paintings, and the PVA for acrylic paintings, a couple of coats. :)

[@adriennesilva6707]

@@DaveUsherArt Dear Dave I hope I described my issue fluently! I am speaking about an older already made oil painting I want to cover over with a gesso - Dulux Velvaglo , PVA glue and glycerine. A valuable recipe, however I lost the proportions. This is a way to ‘start over’ . You know about this? I did this 21 years ago and the ‘new’ painting is 100% stable. So in other words I painted over an older oil painting with a gesso ground- just need to be re-informed about the proportions of the Acrylic paint, the PVA glue and the glycerine.

Please what is the name of material with blue color?

Obstetric Veterinary gel. It's an acrylic lubricant.

[@arturojimenez7087]

@@DaveUsherArt What exactly do you use it for? Does it keep acrylic paints from drying too quickly?

Maybe it's my OCD but the bits that were left at the edges really bugged me.

[@DaveUsherArt]

Hello Mike thanks for your comment: haven't got a clue what you're talking about, this was from 3 years ago, must be the OCD! Lol! :)

[@kuldipdegon7310]

Why don’t you leave and let if dry naturally

[@DaveUsherArt]

To answer your question, because I want to get on with the painting! :)

[@offrampt]

The idea of grinding up chalk sends shivers down me spine. Does this work for gouache?

[@DaveUsherArt]

The chalk is very fine and mixes with gesso very well, it's for chalk lines. I used it a lot when I was planning where to cut and plan carpets in my business.
