Suggestions: use a bigger brush like 1” ; allow 1st coat of rabbit glue on board to set, apply second coat then attach paper. 1st coat of rabbit glue may seal the board. Don’t know if that solves the acid problem mention by previous commenter. For the short run, I’d give it a try…
If u want to glue paper to a board etc, the glue have to be stronger - about 12 percent. Glue for just overgluing the paper should be at least half of this percentage, ideally about 7 percent. Before gluing on the paper, paper HAVE TO be gently wetted first, you ALWAYS aply glue on wet paper and by that - already loosened paper - never directly on dry paper. A mistake is also that you press the paper to much and with a wrong sharp tool - your tool leaves marks. more glue of low percentage leaves bubbles - thats a mistake too. Proper way: U get your paper wet, aply one even coat of 12% glue and just gently press the paper using your palm to previously doublesidedly overglued and dried board. No extensive pressing and irritating of paper. Imprimitura on paper should me made not with oil but with slightly coloured glue of low percentage around 6 to 7 percent. You just add a little of pigment into small amount of glue and quickly apply it over paper. This is how they made imprimitura on paper in old times. Your imprimitura looks like the oil and turpentine are soaking into the paper - it means that paper is not overglued properly. Glue on paper works as isolation layer - oil SHOULD NOT have any acces to paper tissues. If the oil sinks into the paper after overgluing it means that the layer of glue is to thin /too little glue, too weak glue/ - each paper is diffrent, each glue is diffrent - this is why u always have to make tests first. Overgluing layer should be tight enough to just not let any oil go through it and get into the body of paper. Oil should stay completely on the surface of the glue. This is why u have to very carefully measure the percentage - for overgluing it should be about 7 percent, if the paper is glued onto board - glue can be stronger than 7 percent. In fact paintings on acid-free paper are way stronger and stable than grounded canvas. Many painters have sketched on glued paper and those sketches are preserved excellently what cant be said about their works on canvas.
We’ll put. Perhaps I engage in overkill as I hand rub a second thin layer of calcium and glue on the stretched and sized paper followed by a third hand rubbed layer of glue calcium and oil. I know this sounds thick but it really isn’t. I use very heavy weight linen rag.
Are you suggesting you leave the paper glued to that board? If so you are in for a disaster. The board you show is not plywood, it is some form of particle board. It is full of acid.

Can you please do a video about a quick and easy lighting setup for best results? Thanks
Cool idea. Thanks!
Really interesting practice surface. I kinda want a bigger brush, but the squeegee is genius.

hi guys!
Is the relationship between glue and water the same for sewing fabrics?
Great video. Greetings from Brazil
thx greatings from mexico

what happens then? and why is it bad if it has a lot of acid?
